EXECUTIVE SUMMARY

The Mississippi Department of Transportation (MDOT), the Federal Railroad Administration (FRA),

and the Hancock County Port and Harbor Commission (HCPHC) are preparing an Environmental 

Impact Statement (EIS) to evaluate a proposed new freight rail line that would provide a direct 

connection between the Port Bienville Railroad (PBVR) and the Norfolk Southern (NS) rail line near 

Interstate 59 (I-59), north of National Aeronautics and Space Administration’s (NASA’s) John C. 

Stennis Space Center. This railroad would provide a second Class I rail connection to Port Bienville 

and the Port Bienville Industrial Park. 

The project is approximately 24 miles in length and located in the southwestern part of the state of 

Mississippi. For the purpose of the wetland and Threatened and Endangered (T&E) species

investigations detailed in this report, a 200-foot (ft) survey corridor that buffered the reasonable

project (rail) alignment, as identified through the alternatives analysis, was used as the survey area. 

Throughout this document, “survey corridor” refers to this 200-ft wide area evaluated for wetlands 

and T&E. This survey corridor was evaluated in numbered segments (Chapter 4) of the reasonable

alignment for existing wetlands and protected species.

It is anticipated that the proposed project will cross six (6) named streams within the project area. 

From North to South, these include: Alligator Branch (currently bridged), Second Alligator Branch, 

Indian Camp Branch, Turtleskin Creek, Wolf Branch, and Bayou LaCroix. An additional seven (7) 

unnamed streams were also identified throughout the study corridor. These include one perennial 

stream, 5 intermittent streams and one ephemeral stream. The proposed project will also cross 

additional jurisdictional features including Lower Devils Swamp and Mulatto Bayou located 

immediately north and south of Old Lower Bay Road, respectively. 

A total of 83 wetland areas (343.02 acres total), 8 open waters (3.84 acres total) and 2 riverine 

areas (0.40 acres total) were identified within the approximately 575-acre survey corridor 

for the proposed rail line (See Appendix B). 13 (thirteen) streams cross the corridor for a total 

of approximately 4,065 linear feet (LF). Wetland habitats have been classified as emergent, 

bottomland hardwood, scrub-shrub, and pine savannah. Other waters were classified as either open 

waters or riverine. Streams were classified as ephemeral, intermittent and perennial. These 

wetlands and other waters are considered potentially jurisdictional (i.e., waters of the U.S.) until 

concurrence is given by a representative of the U.S. Army Corps of Engineers (USACE), Regulatory 

Branch, through the jurisdictional determination (JD) process. 

Federally listed, state listed, and federal candidate species that may occur in or near the project area 

are listed in Table 1.

We recommend a determination of no effect for the following federally protected species because the 

proposed action will not affect these listed species or critical habitat: Alabama (=inflated) heelsplitter 

(Potamilus inflatus), pearl darter (Percina aurora), Atlantic sturgeon (Acipenser oxyrinchus desotoi), 

smalltooth sawfish (Percina aurora), gopher tortoise (Gopherus polyphemus), ringed map turtle 

(Graptemys oculifera), black pine snake (Pituophis melanoleucus lodingi), Kemp’s ridley sea turtle 

(Lepidochelys kempii), leatherback sea turtle (Dermochelys coriacea), loggerhead sea turtle (Caretta

caretta), Hawksbill sea turtle (Eretmochelys imbricate), piping plover (Charadrius melodus), red knot

CHAPTER 1. INTRODUCTION

The purpose of this report for the proposed Port Bienville Railroad is to identify and describe the 

presence and approximate extent of jurisdictional wetlands and other waters of the U.S. as defined 

in Section 404 of the Clean Water Act, 33 U.S.C. 1251-1387 and/or Section 10 of the Rivers and 

Harbors Act of 1899. 

The proposed project will involve the construction of a railroad track on a new location, as well as 

the restoration and rehabilitation of approximately 5.4 miles of existing railroad track. The purpose 

of the project is to construct a new railroad line to support the needs of the Port Bienville Industrial 

Park, its tenants, and other industries in the area. A new dual Class I railroad connection to serve the 

Port Bienville Industrial Park and surrounding area would:

• improve rail transport time and reliability;

• foster greater economic opportunities and attract new industries to Hancock and Pearl River 

Counties; and

• allow/increase/create flexibility in rail transportation options during storms and other 

emergencies.

The project is approximately 24 miles in length and located in the southwestern part of the state of 

Mississippi (Figure 1). For the purpose of the wetland and Threatened and Endangered species

investigations detailed in this report, a 200-foot (ft) survey corridor that buffered the reasonable

project (rail) alignment, as identified through the alternatives analysis, was used as the survey 

corridor (Figure 2). The rail line would require a 100-ft Right-Of-Way (ROW). Using a 200-ft corridor 

provides a 50-ft buffer on either side of the ROW limits, allowing for minor adjust if required. 

Throughout this document, “survey corridor” refers to this 200-ft wide area evaluated for wetlands 

and T&E. This survey corridor was evaluated in numbered segments (Chapter 4) of the preferred 

alignment for existing wetlands and protected species.

Resources having the potential to be jurisdictional were delineated in the survey corridor centered 

along the reasonable alignment, which begins at the existing Port Bienville Railroad and travels north 

approximately 24 miles to the Norfolk Southern railroad near U.S. Highway 11 and Jackson Landing 

Road (Figures 1, 2, and 3). In addition to documenting wetland and water features, this report 

documents the findings of any potential occurrence and/or effect to any state or federally listed 

threatened or endangered species found within the wetlands and T&E survey corridors.

In the absence of a permit application and Jurisdictional Determination (JD) for the proposed project, 

a planning-level waters of the U.S. evaluation was developed by staff scientists in order to facilitate 

discussion of water resources within the survey corridor in the EIS, as well as potential impacts to 

water resources as a result of the proposed project and its alternatives. The planning-level data were 

first modeled using Geographic Information Systems (GIS). This dataset was then ground-truthed 

and refined by wetlands staff of CDM Smith and HDR, Engineering, Inc. (HDR) in March/April 2016 

and in June 2016 to determine the accuracy of streams and wetlands identified by GIS. Streams and 

wetlands were identified in the field using the three-parameter approach as defined in the USACE 

1987 Manual mentioned in Chapter 2. All wetland/upland boundaries found within the 200-ft wide 

survey corridor were mapped using Trimble Geo XH Differential Global Positioning Systems (GPS) 

technology with a Global Navigation Satellite System (GNSS), which reports to sub-meter accuracy. 

The GPS data were collected using ArcPad and Terrasync software and exported to shapefile format. 

The information gathered in the field was used to verify the presence of the predicted stream and 

wetland features, to add features not predicted, and to adjust boundaries of wetlands, open water, or 

streams. It is assumed that all wetlands within the survey corridor have the potential to be 

jurisdictional; however, their jurisdictional status has not been verified with the regulatory agencies.

CHAPTER 2. METHODS 

An evaluation of the presence and approximate extent of jurisdictional wetlands and other waters of 

the U.S. as defined in Section 404 of the Clean Water Act was conducted for the Port Bienville Railroad 

project. The term “jurisdictional” refers to the legal authority assigned to the U.S. Army Corps of 

Engineers (USACE) to regulate wetlands and other waters. For the purposes of this report, the term 

“wetland” as defined by the USACE and the U.S. Environmental Project Agency (EPA) shall mean:

Those areas that are inundated or saturated by surface water or ground water at a 

frequency and duration sufficient to support, and that under normal circumstances do 

support, a prevalence of vegetation typically adapted for life in saturated soil conditions.

For the purposes of this report, the term “other waters of the U.S. (OWUS)” as defined by the USACE 

shall mean: 

All other waters such as intrastate lakes, rivers, streams (including intermittent 

streams), mudflats, sandflats, sloughs, prairie potholes, wet meadows, playa lakes, or 

natural ponds, which the use, degradation or destruction of could affect interstate or 

foreign commerce including any such waters:

i. which are or could be used by interstate or foreign travelers for 

recreational or other purposes; or

ii. from which fish or shellfish are or could be taken and sold in interstate 

or foreign commerce; or 

iii. which are used or could be used for industrial purposes by industries 

in interstate commerce.

The wetland delineation methods follow the procedures outlined in Part IV of the USACE Wetland 

Delineation Manual dated 1987 and the Regional Supplement to the Corps of Engineers Wetland 

Delineation Manual: Atlantic and Gulf Coastal Plain Region dated 2010. A full list of the methods and 

tools used may be found in Appendix A at the end of this document. Other sources of information 

used in the wetland delineation include:

• “Soil Survey for Hancock County, MS,” US Department of Agriculture Natural Resources Soil 

Conservation Service (NRCS), 1981 (U.S. Department of Agriculture [USDA] 1981);

• “Redoximorphic Features for Identifying Aquic Conditions,” North Carolina Agricultural 

Research Service (ARS), Technical Bulletin 301 (N.C. ARS 1992);

• Field Indicators of Hydric Soils. Version 7. NRCS, 2010 (USDA 2010).

• English Lookout, Logtown, Dead Tiger Creek and Nicholson, Mississippi USGS Topographic 

Quadrangle maps, U.S. Geological Survey (USGS 2012);

• Onsite evaluation of soils, vegetation, and hydrology. 

Streams and drains within the survey corridor were inspected on-site to determine if they should be 

considered OWUS. Current terminology for jurisdictional streams and drains is Traditional 

Navigable Waters (TNW) and Relatively Permanent Waters (RPW) (Rapanos 2008, USACE 2007a). 
Draft Wetlands and Threatened and Endangered Species Report • Methods

7 Project No. FRA-0023-00(003)/105494 101000-102000

Perennial and intermittent streams addressed in this report are considered to be RPWs. Ephemeral 

streams (i.e., none identified with a significant nexus to a TNW) addressed in this report are 

considered to be non-RPW wet-weather conveyances through uplands. Final jurisdictional 

determinations of all streams are given only by a representative of the USACE.

The presence of an “ordinary high water mark” (OHWM) was used as a primary guide to determine 

potential jurisdictional limits for OWUS. In accordance with USACE (2005), this is indicated by the 

following flow characteristics: natural line impressed on the bank; the presence of litter and debris; 

changes in the character of soil; destruction of terrestrial vegetation; shelving; the presence of a 

wrack line; vegetation matted down, bent, or absent; sediment sorting; leaf litter disturbed or washed 

away; scour; sediment deposition; multiple observed or predicted flow events; water staining; and 

abrupt change in plant community. Three USACE documents were used as secondary guides to help 

determine jurisdictional status of potential OWUS: 

• The Approved Jurisdictional Determination Form, “JD form”, 30 May 2007 (USACE 2007a);

• Regulatory Guidance Letter (RGL) 07-01, 5 June 2007 (USACE 2007b); and

• RGL 05-05, 7 December 2005 (USACE 2005). 

2.1 STREAM CLASSIFICATION

Jurisdictional boundaries for streams and open waters were delineated at the OHWM in the field. 

Methods used to determine the category of each stream (e.g., perennial, intermittent, or ephemeral) 

include characterizing the type of substrate, evidence of groundwater seepage, percentage of reaches 

with gain and loss, type of vegetation, and evidence of flow volume. Data was also collected on the 

apparent condition of each stream reach such as channel condition, riparian buffer vegetation, instream habitat, and hydrologic setting. Streams are classified based on potential navigability and flow 

regime, and include: TNWs, RPWs (perennial or seasonal), and non-RPWs (i.e., ephemeral streams).

The jurisdictional status of constructed ponds depends on whether they were constructed as an 

impoundment of a jurisdictional stream or if they were constructed in uplands, away from waters of 

the U.S. However, the jurisdictional status of constructed ponds also depends on whether they have 

a surface hydrological connection to a water of the U.S. under normal conditions. If a pond lacks a 

drainage pipe (or other means) that provides flow sufficient to establish an OHWM directly 

downstream to a water of the U.S., then it may be considered a non-jurisdictional aquatic feature. 

Ditches (including roadside ditches) excavated wholly in and draining only uplands, that did not 

carry a relatively permanent flow of water, were omitted as tributaries and did not have a significant 

nexus to a TNW were not considered OWUS. Swales, ephemeral streams, and erosion features (e.g., 

gullies, small washes characterized by low volume, infrequent, and short duration flow) were, 

likewise, not considered jurisdictional if they were not tributaries and did not have a significant 

nexus to a TNW. Even when not OWUS, these geographic features (e.g., swales, ditches) could, 

however, still contribute to a surface hydrologic connection between an adjacent wetland and a TNW. 

Manmade ponds, sediment control basins, borrow pits, and other non-flowing open water areas were 

assumed to be OWUS.

A Wide Area Augmentation System (WAAS)-enabled GPS was used to determine the latitude and 

longitude of the areas where data were collected and where site photographs were taken. Accuracy 

of the positions shown is typically one to three feet depending on tree cover. GPS track data were

collected and used as an aid to accurately depict wetland/non-wetland boundaries on maps used in 

this report. 

Field surveys were conducted during March/April 2016 and June 2016. All wetlands, streams, and 

waterbody features found within the survey corridor were identified, described, and documented. 

After field work was completed, data was entered into GIS software (ESRI ArcMap 10.2.1), potentially 

jurisdictional areas were mapped, and areas and lengths of existing waters and wetlands within the 

survey corridor were calculated. Results from the GIS analysis can be found in Chapter 4 and 

Appendix B. All areas identified should be considered potentially jurisdictional until concurrence is 

given by a representative of the USACE, Regulatory Branch, through the JD process.

CHAPTER 3. EXISTING CONDITIONS

Based upon the field delineation, there were a total of 83 (eighty-three) wetland areas (343.02 

acres), 8 (eight) open water areas (3.84 acres) and 2 (two) riverine areas (0.40 acres), 

identified within the survey corridor (See Appendix B). A total of thirteen streams were identified 

throughout the corridor for an approximate total of 4,065 linear feet. All potential jurisdictional 

areas should be considered preliminary prior to confirmation by the USACE Regulatory Branch. 

Findings for each segment are shown in Tables 4 through 13 in Chapter 4, as well a complete dataset 

in Appendix C.

3.1 TERRAIN

The majority of the survey corridor consists of prior-converted pine plantations of loblolly (Pinus 

taeda) and slash (Pinus elliottii) pines. The terrain is very flat with minor changes in elevations 

around drainages and bayous. The elevations for the survey corridor range from the high point at 

approximately 25 ft Above Sea Level (ASL) to the low point of approximately 8 ft ASL.

3.2 LANDSCAPE SETTING

The proposed project is located within the Southern Coastal Plain physiographic province (EPA 

Ecoregion Level III). This area extends from Virginia to Louisiana and Mississippi of the Coastal Plain 

Province of the Atlantic Plain. Longleaf pine flatwoods and savannas historically dominated the 

Southern Coastal Plain, but it now consists of a variety of other communities including slash pine 

(Pinus eliotii), pond pine (Pinus serotina), pond cypress (Taxodium ascendens), American beech 

(Fagus grandifolia), sweetgum (Liquidambar styraciflua), southern magnolia (Magnolia grandiflora), 

white oak (Quercus alba), and laurel oak (Quercus laurifolia) forests. Most of the floodplains consist 

of bald cypress (Taxodium distichum), pond cypress, water tupelo (Nyssa aquatica), bottomland oaks, 

sweetgum, green ash (Fraxinus pennsylvanica), and water hickory (Carya aquatica). 

Defined further, the survey corridor lies primarily within the Gulf Coast Flatwoods (EPA Ecoregion 

Level IV), which is described as a narrow region of nearly level terraces and delta deposits composed 

of Quaternary sands and clays. The Gulf Coast Flatwoods consists of wet, sandy flats and broad 

depressions that are locally swampy and usually forested, while some of the better-drained land has 

been cleared for pasture or crops. The area includes bottomland hardwood forests, scrub-shrub 

wetlands, emergent wetlands, upland scrub-shrub, agriculture (rice farming), and residential 

properties. 

3.3 LAND USES

The majority of the survey corridor runs through the approximately 125,000 acre Stennis Space 

Center acoustical buffer zone. The buffer zone surrounding Stennis was established by NASA to 

enable testing of large rocket engines, etc. The buffer zone is critical to NASA’s missions and is 

considered a national asset. The United States government owns a perpetual easement restricting 

certain uses in, on, across and over the land in the buffer zone, and has the right to prohibit habitation 

or occupancy of dwellings and other buildings. The government also has the right to prohibit the 

construction of buildings allowing for, or susceptible to, habitation and reserves the right to remove 

structures in violation of this easement. The easement does permit other uses when those activities 
Draft Wetlands and Threatened and Endangered Species Report • Existing Conditions

10 Project No. FRA-0023-00(003)/105494 101000-102000

do not interfere with or reduce the rights of the government. Examples of these other uses include 

hunting, fishing, or general silviculture practices.

The remaining area of the survey corridor that lies outside of the Stennis Space Center acoustical 

buffer zone is primarily rural, with a few residences north of Port Bienville. The area contains several 

rights of way for utility uses including gas pipelines and electric transmission lines. 

3.4 HYDROLOGY

3.4.1 Watershed

The survey corridor is comprised of many bayous and unnamed tributaries of the Pearl River Basin. 

The Pearl River Basin is found in central and southern Mississippi and covers over 8,700 square 

miles. The basins’ rivers and tributaries drains all or parts of 24 counties in Mississippi and three 

parishes in Louisiana. Over 16,000 miles of streams and rivers flow through the basin. Subwatersheds of the Pearl River Basin include Fannegusha Creek, Mill Creek, the Strong River, Magees 

Creek, West Boley Creek, and Mike’s River (MDEQ, 2007). The project’s survey corridor falls within 

the Lower Pearl River watershed. 

The natural hydrology has been heavily altered in the area due to silvicultural activities including 

ditching, rowing, and logging within the numerous pine plantations that account for most of the 

survey corridor. The saturated and flooded conditions in portions of the area can be attributed to 

riverine influences of the Pearl River through its bayous and tributaries, a high-water table, and 

geographic location within the 100-year floodplain. The 100-year floodplain is identified as those 

areas with the 1 percent annual chance flood (100-year flood). Also, known as the base flood, it is the 

flood that has a 1 percent chance of being equaled or exceeded in a given year. This Special Flood 

Hazard Area is the area subject to flooding by the annual 1 percent chance flood. Areas of Special 

Flood Hazard include Zones A, AE, AH, AO, AR, A99, V, and VE. Areas classified as Zone X include the 

area subject to 0.2 percent annual chance flood (500-year flood). Approximately 192 acres of the 

survey corridor falls within Zones A and AE (1 percent chance annual flood) and 327 acres falls in 

Zone X. 

Flood data obtained from FEMA is detailed in Table 2 and shown on exhibits in Appendix D.

3.4.2 Climate

Hancock County, Mississippi and Pearl River County, Mississippi receive 65 inches and 63 inches of 

rain per year, respectively, on average. The number of days with any measurable precipitation in 

Hancock County is 101 and 105 for Pearl River County (Sperling’s Best Places 2016). 

In the days prior to the first field survey, Louisiana and parts of Southwest Mississippi experienced 

record rainfall and flooding with totals of over 26 inches of rain between March 8 and March 11, 

2016.2 The project survey corridor is situated within the Pearl River Basin. Due to flooding, the Pearl 

River experienced its second highest crest in history of 20.35 ft on March 14, 2016, the day fieldwork 

began.3 Flood stage for the Pearl River is 14 ft.

4 The recent heavy rainfall and flood stage of the Pearl 

River caused flooding throughout the extent of the area and conditions may have been wetter than 

normal. During a second field visit for the southern alignment in June 2016 under normal conditions, 

portions of the proposed corridor were still heavily saturated or ponded with standing water varying 

between 3 to 12 inches.

Although a defined surface hydrologic connection to the Pearl River is not clearly apparent in all 

areas, it is assumed that wetlands and streams in the survey corridor would be considered 

jurisdictional due to their location within the floodplain.

Zone A: 1 percent annual chance flood. No Base Flood Elevations determined.

 Zone AE: 1 percent annual chance flood. Base Flood Elevations Determined. Floodways, such as channels or streams plus any adjacent floodplain, 

must be kept free of encroachment so that the 1 percent annual chance flood can be carried without substantial increase in flood heights. 

 Zone X: Areas of 0.2 percent annual chance flood; areas of 1percent annual chance flood with average depths of less than 1 foot or with drainage 

areas less than 1 square mile; and areas protected by levees from the 1 percent annual chance flood.

3.5 VEGETATION

The survey corridor contains six general habitat types (Table 3). These are broadly determined from 

the dominant vegetation and may contain some overlap of species. 

Table 3. Habitat Types

Dominant Vegetation Types Wetland/Upland Classification

Pine Plantation Upland

Early Succession Pine Plantation Upland

Pine Savannah/Pine Flatwoods Wetland

Bottomland Hardwoods Wetland

Scrub-Shrub Wetland

Emergent Wetland

3.5.1 Pine Plantation – Upland

Areas of planted pine are very common throughout Mississippi. This major component of 

Mississippi’s economic base covers approximately 19.6 million acres, or 65 percent of the state’s total 

land area. This habitat was characterized by an overstory composed primarily of loblolly pine. These 

areas were intensively managed for silviculture with a first thinning occurring typically at ages 12 to 

15 years, followed by a clearcut at typically 25 to 30 years old. These areas were bedded and 

extensively ditched. The survey corridor spanned multiple stands of pines, ranging from open 

thinned (60 to 80 Basal Area) stands to dense, pre-merchantable stands (120 to 140 Basal Area). As 

a result of recent clearcut harvests, some areas were devoid of overstory or midstory. In the thinned 

pine areas (60 to 80 BA), the midstory consisted of sweet gum and red maple (Acer rubrum) with 

approximately 10 to 25 percent cover. In the denser pine areas (120 to 140 BA) no midstory or shrub 

layer was present due to 90 to 100 percent overstory cover. In the open thinned pine stands the 

shrub layer consisted of wax myrtle (Morella cerifera), redbay, (Magnolia virginiana), fetterbush 

(Lyonia lucida), and Vaccinium, with 10 to 30 percent cover. The herbaceous layer was also 

somewhat sparse, approximately 0 to 10 percent cover, and was composed primarily of dwarf 

palmetto (Sabal minor), longleaf woodoats (Chasmanthium sessiliflorum), plumegrass (Saccharum 

giganteum), giant cane (Arundinaria gigantea), Virginia chain fern (Woodwardia virginiana), 

cinnamon fern (Osmundastrum cinnamomeum), and netted chain fern (Woodwardia areolata). These 

areas were bedded, ditched, and drained extensively.

3.5.2 Early Succession Pine Plantation - Upland

Early successional pine plantation habitat originates from the harvest and replanting of a mature 

upland pine plantation community that previously existed in the area. Soils and hydrology are 

characteristic of an upland pine plantation, including well-drained soils with no indication of 

saturation or presence of surface water. Regrowth in early successional habitats includes a sapling 

and scrub/shrub overstory interspersed with a grass and forb understory.

During the survey, these areas were identified among intermediate-aged and mature upland pine 

plantations. Dominant species observed during field surveys include loblolly pine saplings and 

gallberry, interspersed with broomsedge bluestem (Andropogon virginicus). Even after a rainfall of 

approximately 2 inches the day prior to the survey of these areas, no surface water or saturation was 

observed. This is due to the well-drained sandy soils identified during the survey, which are

characteristic of upland areas. 
Draft Wetlands and Threatened and Endangered Species Report • Existing Conditions

13 Project No. FRA-0023-00(003)/105494 101000-102000

3.5.3 Pine Savannah/Pine Flatwoods – Wetland

Pine savannah/pine flatwoods is the most common habitat type found throughout the survey 

corridor. Many of these areas are maintained for silviculture and are constantly changing due to 

harvesting, planting or thinning. This habitat is essentially flat or rolling topography with a canopy 

of pines along with a well-developed subcanopy of several tall shrub or understory species. The soils 

are usually sandy with a high-water table. 

Similar to the upland pine plantations observed, the pine flatwoods contain a variety of planted pine 

species with the majority being loblolly and slash pine. Longleaf pine may be present but has mostly 

been removed in favor of the faster growing previously mentioned species. This habitat was 

previously fire dependent but now is typically man-altered through the use of thinning, selective 

harvesting and/or ditching. In contrast to the upland pine plantation, here a clear herbaceous 

understory is present, and where not maintained, it is dominated by one or two species throughout. 

These were generally swamp titi (Cyprilla racemiflora) and fetterbush. Other species observed 

include inkberry (Ilex glabra), wax myrtle (Morella cerifera), sweetbay (Magnolia virginiana), and

redbay (Persea borbonia). The groundcover contains a variety of panic grasses (Panicum spp.), 

blazing-stars (Liatris spp.), St. John’s worts (Hypericum spp.), and broom sedges (Andropogon spp.). 

Some of the less-common but ecologically important herbs observed included pitcher plants 

(Sarracenia spp.), sundews (Drosera spp.), and club mosses (Lycopodium spp.).

3.5.4 Bottomland Hardwoods – Wetland

Bottomland hardwood forests are typically associated with floodplains of rivers and streams. These 

forests are characterized and maintained by a natural hydrologic regime of alternating wet and dry 

periods generally following seasonal flooding events. These habitats can vary widely in species and 

water level fluctuations depending on proximity to the associated water source and rainfall events 

throughout the year. These communities are defined by a well-developed canopy of swamp tupelo 

(Nyssa spp.), bald cypress, red maple, sweetgum, boxelder (Acer negundo), cherrybark oak (Quercus 

pagoda), and American sycamore (Platanus occidentalis). Overstory closure ranged from 30 to 50 

percent.

During parts of the year, particularly in wetter months, little to no herbaceous vegetation may be 

present due to standing water throughout these flooded forests. A subcanopy of early successional 

species, plus many tall shrubs, are typically present. These include Chinese privet (Ligustrum 

sinense), arrowwood viburnum (Viburnum dentatum), wax myrtle, and black willow (Salix nigra). 

Vines were also very common in these communities, including greenbrier (Smilax spp.), poison ivy

(Toxicodendron radicans), and muscadine grape (Vitis rotundifolia). Standing water was present 

within most of the bottomland hardwood forest habitats with a typical subcanopy/shrub layer of 

cover at 10 to 20 percent.

3.5.5 Scrub-Shrub – Wetland

Scrub-Shrub wetlands are usually a low, flat wetland community dominated by woody vegetation, 

less than 20 ft tall. Soils are very poorly drained, and surface water is present for extended periods, 

sometimes drying during late summer or during periods of drought. Species include true shrubs, 

young trees, and shrubs or trees that are stunted due to some environmental conditions. 
Draft Wetlands and Threatened and Endangered Species Report • Existing Conditions

14 Project No. FRA-0023-00(003)/105494 101000-102000

Dominant shrub species observed during field surveys include wax myrtle, swamp titi, fetterbush, 

and gallberry (Ilex coriacea). Redbay and stunted bald cypress were also observed in several areas 

throughout the survey corridor. Field conditions at the time were extremely wet and very few 

herbaceous plants were observed. Vines were very common within the upland and wetland 

ecotones. Some of the species included blackberry (Rubus spp.), poison ivy, muscadine grape, and

greenbrier. 

3.5.6 Emergent – Wetland

Emergent wetlands, also referred to as freshwater marshes, are common in maintained rights of way 

throughout the survey corridor. These areas were often found alongside or adjacent to a forested 

wetland habitat type described above. This community is dominated by grasses and sedges as well 

as other herbs, including panic grasses, beak sedges (Rhynchospora spp.), sedges (Carex spp.), black 

needlerush (Juncus roemerianus), cattails (Typha spp.), and water pennyworts (Hydrocotyle spp.). 

These areas were mostly found near gas pipelines or rights of way for overhead transmission lines 

where woody vegetation is either physically removed or treated with herbicides to maintain the 

herbaceous community. During site visits, many of these areas were extremely wet with water as 

much as 3 to 4 ft deep. 

3.6 SOILS

A custom soil survey report for the survey corridor of the Port Bienville project was obtained on June 

20, 2016 from the online NRCS Soil Survey for Hancock (MS045) and Pearl River (MS109) Counties, 

Mississippi (Appendix E). The Soil Surveys contain information that affects land use planning in 

survey areas of interest (AOI). They highlight soil limitations that affect various land uses and provide 

information about the properties of soils in the survey areas. The custom Soil Survey Report for the 

proposed reasonable alignment for the Port Bienville project (Appendix E) contains soil 

characteristic information and total area (acres) of each mapped soil unit in the projects AOI.

For Hancock County, Mississippi, the NRCS Web Soil Survey (2011) indicates that the mapped soil 

types of the project’s survey corridor include: Atmore silt loam (At), Beauregard silt loam (Be), 

Escambia loam (EsA), Escambia loam (EsB), Eustis loamy fine sand (EuB), Guyton silt loam (Gu), 

Harleston fine sandy loam (HIA and HIB), Malbis fine sandy loam (MaB), McLaurin fine sandy loam 

(McB), Poarch fine sandy loam (PoA ,PoB, and PoC), Saucier fine sandy loam (SaA and SaB), SaucierSusquehanna complex (ScB), Smithton fine sandy loam (St), Smithton fine sandy loam, frequently 

flooded (Su), Smithton association, frequently flooded (SW), and Trebloc association, frequently 

flooded (TR). For Pearl River County, Mississippi, the mapped soil types of the survey corridor

include: Bibb sandy loam (Bd), Escambia fine sandy loam (EaA), Pits (Pa), Poarch loam (PoA), and 

Saucier loam (SaA). A description of each soil series or map unit within the project’s AOI is provided 

below (https://soilseries.sc.egov.usda.gov).

gently sloping Coastal Plains. They are saturated for short periods during winter and early spring. 

Water runs off the surface at a medium to slow rate. Slope is dominantly 1 to 3 percent, but ranges 

from 0 to 5 percent.

The Escambia series consists of very deep, somewhat poorly drained, moderately to slowly 

permeable soils in the Southern Coastal Plain (MLRA 133A) and the Eastern Gulf Coast Flatwoods 

(MLRA 152A). They formed in sandy and loamy marine sediments of the Lower Coastal Plain. Slopes 

range from 0 to 8 percent.

soils that formed in thick loamy sediments. These soils are on Coastal Plain local stream flood plains 

and in depressional areas on late Pleistocene age terraces. Slopes range from 0 to 1 percent.

The Harleston series consists of very deep, moderately well-drained, moderately permeable soils on 

terraces and uplands of the Southern Coastal Plain (MLRA 133A) and the Eastern Gulf Coast 

Flatwoods (MLRA 152A) Major Land Resource Areas. They formed in marine or stream deposits 

consisting of thick beds of sandy and loamy material. Slopes range from 0 to 12 percent.

The Malbis series consists of very deep, moderately well or well-drained, moderately slowly 

permeable soils on broad interfluves and uplands of the Southern Coastal Plain (MLRA 133). They 

formed in loamy sediments of the Coastal Plain. Slopes range from 0 to 12 percent.

The McLaurin series consists of very deep, well-drained, moderately permeable soils on dissected 

fluviomarine terraces of the Southern Coastal Plain Major Land Resource Area (MLRA 133A). They 

formed in loamy marine or stream sediments. Slopes range from 0 to 8 percent.

The Poarch series consists of very deep, moderately well and well-drained, moderately permeable 

soils on uplands of the Southern Coastal Plain Major Land Resource Area (MLRA 133A). They formed 

in unconsolidated sandy and loamy marine sediments. Slopes range from 0 to 8 percent.

The Saucier series consists of moderately well-drained, slowly permeable soils that have a moderate 

amount of plinthite in the subsoil. These soils formed in marine sediment that is loamy in the upper 

part and clayey in the lower part. These are nearly level to strongly sloping soils on upland ridges 

and hillsides of the Southern Coastal Plain and Eastern Gulf Coast Flatwoods. Slopes range from 0 to 

12 percent.

The Susquehanna series consists of deep, somewhat poorly drained, soils that formed in marine or 

stream deposits of silty clay and clay. Permeability is very slow. These nearly level to steep soils are 

on erosional uplands of the Southern Coastal Plain. Slopes range from 1 to 17 percent.

The Smithton series consists of very deep, poorly drained, moderately slowly permeable soils that 

formed in loamy alluvial sediments. These level to nearly level soils are on Pleistocene and younger 

stream terraces of the Western and Southern Coastal Plains. Slopes are dominantly less than 1 

percent, but range to 3 percent.

The Trebloc series consists of nearly level, poorly drained soils. Permeability is slow. These soils 

formed in moderately fine textured marine or fluvial sediment and are on stream terraces and in 

depressions on drainage ways on the uplands in the Eastern Gulf Coastal Flatwoods and the Southern 

Coastal Plain. Slopes are 0 to 2 percent.

The rail corridor alignment will intersect numerous soil types as indicated above. Characteristics 

such as color, texture, and the presence of redoximorphic features were recorded on Wetland 

Determination Data Forms – Atlantic and Gulf Coastal Plain Region for each data plot where an 

original soil sample was taken during the field wetland delineation. Wetland Determination Data 

Forms representative of each habitat type can be found in Appendix F. Photo log of field work can 

be found in Appendix G.

CHAPTER 4. SURVEY RESULTS BY CORRIDOR SEGMENTS

4.1 SEGMENT 11 

Segment 11 is approximately 3.44 miles long and is located at the northern end of the survey corridor 

near Nicholson, Mississippi. Dominant land uses include prior-converted pine plantations, roadways, 

railroad, utility infrastructure, and residential. Existing habitats observed during the site survey 

consist of pine savannah/pine flatwoods, scrub/shrub wetlands, emergent wetland, and upland Pine 

Plantations. The segment also includes roadway, railroad, agriculture drainage features, and swales 

that convey storm water drainage from runoff during rain events. Segment 11 contains the least 

amount of wetlands with approximately 3% of the total acreage for this segment. (Table 4) Nine 

potential waters of the U.S. totaling 2.59 acres were delineated containing Bottomland Hardwoods 

(0.86), Scrub Shrub (0.69), Emergent (0.09), Open Water (0.77), and Riverine (0.18).

Segment 11 crosses a total of eight streams including three named streams of Alligator Branch, 

Second Alligator Branch and Indian Camp branch. (Table 5) Each stream was classified using the NC 

Stream Assessment Method (NC SAM) as mentioned within Chapter 2. The corridor begins near US 

Highway 11 and the existing railroad tracks. Two unnamed intermittent streams were surveyed with 

lengths of approximately 182 and 144 LF adjacent to the existing tracks at the start of the study 

corridor. Found near I-59, Alligator Branch runs diagonally through a box culvert under both the 

existing rail line over I-59 and the I-59 roadway for a total of approximately 240 LF. Outside of the 

culvert, Alligator Branch is a RPW classified as a perennial stream with a defined bed, bank and 

OHWM. On the north side of I-59 S within the survey corridor, Alligator Branch is entirely within a 

culvert under the highway. On the south side of I-59 N, the culvert ends near the survey corridor 

boundary and returns to a natural bottom. The OHWM of Alligator Branch within the survey corridor 

is approximately 40 feet. Uplands are located adjacent to the stream, and include species such as 

sugarberry (Celtis laevigata), water oak (Quercus nigra), southern magnolia (Magnolia grandiflora), 

greenbrier (Smilax sp.), and Chinese privet (Ligustrum sinense). Alligator Branch flows south,

emptying into the Pearl River, a TNW, approximately 1.5 aerial miles south of where it occurs in the 

survey corridor.

Segment 11 also crosses Second Alligator Branch, an RPW classified as a perennial stream with a 

defined bed, bank and OHWM. The width of the stream within the limits of the corridor is an average 

of 36 ft wide therefore it was considered to be riverine for a total of approximately 0.18 acre within 

the corridor. Scrub-shrub wetlands are located adjacent to the stream with dominant vegetation 

species including buttonbush (Cephalanthus occidentalis), panic grass, and giant cane. The stream 

flows southwest into the Pearl River watershed. Stream 5, an unnamed ephemeral tributary of 

Second Alligator Branch, is also found nearby for a total of 93 LF within the study corridor. 

Segment 11 also crosses Indian Camp Branch (Stream 6), an RPW water that is classified as an 

intermittent stream with a defined bed, bank, and OHWM. The OHWM of the stream within the limits 

of the corridor is an average of 6 ft wide. It is a distributary of the Pearl River and generally flows 

east.

Stream 7, a tributary of Indian Camp Branch, an RPW, is classified as an intermittent stream with a 

defined bed, bank and OHWM. The OHWM of the stream within the limits of the corridor is an average 

of 6 ft wide. It generally flows northeast from Indian Camp Branch, eventually draining into a scrubshrub wetland, also located within the Segment 11 corridor. Stream 8, an unnamed intermittent 

stream also crosses the study corridor for a total of approximately 203 linear feet. The average width

of stream 8 within the limits of the corridor is an average of 4 ft wide. These eight streams contained 

with Segment 11 account for over half of the streams found within the approximately 24-mile study 

corridor. 

4.2 SEGMENT 10B 

Segment 10B is approximately 5.17 miles long and is located near the northern end of the project 

survey corridor, between Segments 9 and 11. Dominant land uses within Segment 10B consist of 

roadway and utility infrastructure, and prior converted pine plantations. Existing habitats observed 

during the site survey include pine savannah/pine flatwoods, scrub-shrub wetlands, bottomland 

hardwoods, emergent wetlands and upland pine plantations. The segment consists of approximately

46 percent wetlands and OWUS. (Table 6) Nineteen potential waters of the U.S. totaling 58.38 acres 

were delineated containing Bottomland Hardwoods (2.76), Scrub Shrub (11.95), Emergent (1.68), 

Open Water (0.71), and Pine Savannah (41.28). This survey corridor segment also includes roadway 

and agriculture drainage features and swales that convey infrequent storm water drainage from 

runoff during rain events. 

There are two streams within corridor 10B, one unnamed intermittent stream and a named perennial 

stream. (Table 7) Stream 9, the intermittent stream is approximately 3 feet wide with a defined bed 

and bank as well as an OHWM. The segment is bisected by Turtleskin Creek, a tributary of the Pearl 

River south of Texas Flat Road. Due to rainfall prior to the field survey, the creek was observed 

outside of its banks and no clear channel could be observed. Based upon aerial imagery on an 

adjacent pipeline corridor, it is estimated the creek is typically less than 10 ft wide. Bottomland 

hardwoods were present on either side of the creek, providing a substantial floodplain during and 

after heavy rainfall events.

4.3 SEGMENT 9

Segment 9 is approximately 5.98 miles long and is located between Segments 8A and 10B. The 

segment begins approximately 0.4 miles west of the Texas Flat Road and Mainline Road intersection 

and ends approximately 2.2 miles north of I-10. Dominant land uses within the limits of this corridor 

include prior-converted pine plantation of loblolly and slash pines, roadway, utility infrastructure,

and farmlands. Open water and emergent wetland habitat exist along pipeline and utility right-ofway throughout this segment, likely resulting from disturbance during right-of-way construction and 

maintenance. Other existing habitats observed during the site survey include scrub-shrub wetland, 

pine savannahs, emergent wetlands, bottomland hardwoods, and pine plantation. The majority of 

Segment 9 consists of wetlands or OWUS with over 79 percent delineated as wetlands and another 

1.63 percent delineated as OWUS. (Table 8) Thirty-five potential waters of the U.S. totaling 118.02 

acres were delineated containing Bottomland Hardwoods (17.57), Scrub Shrub (19.78), Emergent 

(3.57), Open Water (2.36), and Pine Savannah (74.74). The corridor segment also includes roadway 

and agriculture drainage features and swales that convey infrequent stormwater drainage from 

runoff during rain events. 

Segment 9 crosses Wolf Branch and an unnamed perennial stream, both tributaries of Catahoula 

Creek. (Table 9) During the site visit in March 2016, Wolf Branch was flooded well beyond its banks. 

From aerial photography it is estimated to have a typical bankfull width of approximately six to eight 

feet. The unnamed tributary was near bankfull, with a width of approximately 6 feet. Both streams 

are bordered on either side by bottomland hardwoods.

4.4 SEGMENT 8A 

Segment 8A is a relatively short segment approximately 0.87 mile and is located between Segments 

7 and 9. This segment consists of mostly pine savannahs and emergent wetlands north of I-10. This 

approximately 21-acre corridor is over 90 percent wetlands. (Table 10) Three potential waters of 

the U.S. totaling 19.05 acres were delineated containing Pine Savannah (9.07) and Emergent (9.98).

No stream crossings were found within this corridor. Land uses in this area were consistent with 

other areas within the Stennis Space Center buffer zone. These include hunt clubs and silviculture 

practices. A large portion of the segment had been recently clear-cut. In this area, standing water 

was present along with several species of pitcher plants and sundews.

4.5 SEGMENT 7 

Segment 7 is approximately 4.84 miles long and is located near the southern end of the survey 

corridor, between Segments 8a and C. The segment begins approximately 1 mile south of US 90 and 

ends 1.5 miles north of Interstate 10 (I-10). Dominant land uses within the Segment 7 corridor 

consist of prior-converted pine plantations of loblolly and slash pines, roadway and utility 

infrastructure, residential, and cattle pasture. Existing habitats observed during the site survey 

include pine plantation, bottomland hardwoods, pine savannah/pine flatwoods, scrub shrub, 

emergent wetlands, and early succession pine plantation uplands. Much larger than Segment 8A, this 

approximately 117-acre corridor consists of 59 percent wetlands. (Table 11) Eighteen potential 

waters of the U.S. totaling 69.34 acres were delineated containing Bottomland Hardwoods (12.37), 

Scrub Shrub (2.27), Emergent (3.35), Pine Savannah (51.13), and Riverine (0.22). The segment also 

includes roadway drainage features that convey infrequent stormwater drainage from runoff during 

rain events.

Segment 7 crosses Bayou Lacroix, an RPW that is classified as a perennial stream. (Table 12) The 

proposed Segment 7 crossing of Bayou Lacroix is located within the northern portion of Segment 7, 

approximately 0.4 miles south of I-10. During field surveys, stream water levels were higher than 

normal due to prior heavy rainfall, resulting in flooding of the riparian zone adjacent to Bayou 

Lacroix. Because the Bayou Lacroix riparian zone was flooded at the time of the field survey, an 

OHWM was not observed in the field. Therefore, aerial imagery was used to identify the approximate 

OHWM of the stream within the limits of the corridor under normal stream flow conditions. The 

width of the stream within the limits of the corridor is an average of 40 ft wide therefore it was 

considered to be riverine for a total of approximately 0.22 acre. Bald cypress, red maple, boxelder, 

loblolly and slash pine dominate the riparian vegetation. Bayou Lacroix generally flows east, 

eventually draining to the Jourdan River, a TNW.

4.6 SEGMENT C (REVISED FROM SEGMENTS 1-6) 

Segment C is approximately 3.39 miles in length beginning at the Port Bienville railroad and ending 

approximately 1-mile south of US-90 and covering approximately 82 acres. The corridor is bisected 

by several unnamed access roads used for both silviculture and pipeline maintenance. The 

abundance of deer stands would indicate this area is predominantly used for hunting purposes. Land 

uses for this area include roadway and utility infrastructure, residential, and hunt clubs in addition 

to silviculture practices that dominate the landscape. 

This survey corridor is extremely low-lying and mostly wet with nearly 97 percent of the corridor 

consisting of bottomland hardwoods, emergent wetlands and modified Pine Savannahs. Nine

potential waters of the U.S. totaling 79.85 acres were delineated containing Bottomland Hardwoods 

(40.97), Emergent (1.08), and Pine Savannah (37.80). (Table 13) No flowing streams were observed 

within this segment during the field surveys in late spring/early summer 2016. Ending at the south

According to available USGS topographic maps, Mulatto Bayou crosses the corridor south of Old 

Lower Bay Road. However, no flow was observed even after several large rain events. The hydrology 

of this area has been heavily altered through silviculture practices as well as a borrow pit found 

adjacent to the survey corridor. The northern end of this corridor traverses a portion of Lower Devils 

Swamp, a tributary of Bayou Philip. Bayou Philip eventually flows into Catahoula Creek found north 

of Waveland, MS.

CHAPTER 5. THREATENED AND ENDANGERED SPECIES

A desktop review of federal and state protected threatened and endangered species, federal 

candidate species, and those species that have been proposed to be listed as threatened or 

endangered under federal law and that could occur within the survey corridor was conducted in June 

and July 2016, see Appendix H. Also, a review of the USFWS letter dated December 12, 2014, of listed 

species that may occur within the project survey corridor was completed. Field surveys for protected 

species were performed concurrent with the wetland delineation, and the 200-foot survey corridor 

was also the survey area used for the T&E evaluation. Various federal and state laws provide 

protection for threatened and endangered plant and animal species.

5.1 FEDERAL

5.1.1 Bald and Golden Eagle Protection Act of 1940

The Bald and Golden Eagle Protection Act of 1940 (16 U.S.C. §§ 668-668c) prohibits anyone without 

a permit issued by the Secretary of the Interior, from taking (pursue, shoot, shoot at, poison, wound, 

kill, capture, trap, collect, molest or disturb) any bald or golden eagles and bald or golden eagles’ 

nests (active, inactive, or seemingly abandoned) under the authority of the U.S. Fish and Wildlife 

Service (USFWS).

5.1.2 Marine Mammal Protection Act of 1972

The Marine Mammal Protection Act (MMPA) (16 U.S.C. §§ 1361-1423h) was enacted in 1972 in 

response to increasing concerns that significant declines in some species of marine mammals were 

caused by human activities. The National Marine Fisheries Service (NMFS) and the USFWS have been 

charged with enforcing the protection of all marine mammals (approximately 125 species) and their 

habitats in accordance with this law, including the take5 of any marine mammals in U.S. waters by 

U.S. citizens on the high seas and the importation of marine mammals and marine mammal products 

into the U.S., which is strictly prohibited. A full list of species protected can be reviewed at 

http://www.nmfs.noaa.gov/pr/species/mammals.

5.1.3 Endangered Species Act of 1973

The purpose of the Endangered Species Act (ESA) of 1973 (16 U.S.C. §§ 1531-1544) is to “protect and 

recover imperiled species and the habitat upon which they depend” and the USFWS and the NMFS 

are the two federal agencies responsible for enforcing this law. Under the provisions of the ESA, the 

listing status of a species under the ESA is determined as either endangered or threatened. 

“Endangered” is defined as a species “in danger of extinction throughout all or a significant portion 

of its range,” and a “threatened” listing denotes a “species that is likely to become endangered within 

the foreseeable future.” Candidate Species is defined as “species for which the USFWS has sufficient 

information to support proposals to list a species as threatened or endangered, and for which the 

service anticipates a listing proposal”. Prior to any federal action, under Section 7 of the ESA, 

consultation with the USFWS and/or the NMFS is required to determine whether any federally listed 

species or designated critical habitat may occur in the area of impact and to determine the proposed

action’s potential effects on these species and/or habitat. All potential impacts to Federally-listed 

species are being coordinated with USFWS in accordance with the ESA.

In addition to listing a species for protection under the ESA, the USFWS may also designate “critical 

habitat” for a species, which is defined by the ESA as:

the specific areas within a geographic area occupied by a species...on which are found 

those physical and biological features essential to the conservation of the species which 

may require special management considerations or protection and specific areas 

outside of the geographical area occupied by the species...upon a determination by the 

Secretary that such areas are essential for the conservation of the species.

5.2 STATE OF MISSISSIPPI

An endangered species, as defined by Mississippi law Nongame and Endangered Species 

Conservation Act 1974, is any species or subspecies of wildlife whose survival and continued welfare 

in the state is in jeopardy or is likely to become so in the near future. (Table 14) Under this law, a 

“take” means to harass, hunt, capture, or kill or attempt to harass, hunt, capture, or kill wildlife. 

Although species become endangered for a variety of reasons, such as loss of habitat, disease, and 

pollution, it has been estimated that man is responsible for the extinction of up to 1,000 species 

worldwide each year. Mississippi has 80 species and subspecies of plants and animals, which are 

officially recognized as endangered. 

The Mississippi Natural Heritage Program (MNHP) identifies and maps in a spatial database (Biotics) 

the localities of Mississippi's rarest plants, animals, exemplary natural communities, and special 

geological features. This database is updated continuously and utilized to portray the distribution of 

each species, to determine its degree of rarity, and assist with development of state, national, and 

global priorities for the preservation of natural diversity.

The MNHP, established in 1976 as a cooperative agreement between The Nature Conservancy (TNC)

and the Mississippi Parks Commission, is part of an international network of State Natural Heritage 

Programs and Conservation Data Centers, all building on the same data collection methodology. Full 

administration of the MNHP was assumed by the Mississippi Department of Wildlife, Fisheries, and 

Parks in 1978.

Inflated Heelsplitter (Alabama) – Federal and State listed – Threatened/Endangered

The inflated heelsplitter has an oval, compressed to moderately inflated, thin shell. The valves may 

gape anteriorly. The umbos are low, and a prominent posterior wing is present that may extend 

anterior to the beak in young individuals. The shell is brown to black and may have green rays in 

young individuals. The umbonal cavity is very shallow and the nacre is pink to purple (USFWS 

2017a). The inflated heelsplitter appears more inflated due to a more developed and rounded 

posterior ridge. The posterior wing of the inflated heelsplitter is more pronounced and abruptly 

rounded over the dorsum.

The preferred habitat of this species is soft, stable substrates in slow to moderate currents. It has 

been found in sand, mud, silt and sandy gravel, but not in large gravel or armored gravel (Hartfield 

1988). It is usually collected on the protected side of bars and may occur in depths over 20 feet. The 

occurrence of this species in silt may not indicate that the life cycle can be successful in that substrate. 

Adult mussels may survive limited amounts of silt where juveniles would suffocate (USFWS 2017a). 

The heelsplitter has been known to use the freshwater drum as a suitable host for its eggs; therefore,

it could potentially be found in any river system the drum inhabits. 

Although this species was historically known to occur within the Pearl River drainage system, it 

currently only occurs within a part of the Tombigbee River drainage system. Recently, this species 

has only been collected at two locations on the Pearl River in Mississippi and in the West Pearl River 

in Louisiana. It still occurs in the Amite River in Louisiana and parts of the Tombigbee River drainage 

in Mississippi. During field reconnaissance, the largest stream encountered was Bayou LaCroix, an 

outlet stream of the Bay St. Louis. The segment of Bayou LeCroix located within the survey corridor

is relatively narrow, but does have slow to moderate currents and silty/clay substrates based on 

NRCS soil data. No sand bars are present in this segment and the depth of the Bayou is less than 20 

ft. Although freshwater drum species (host) may be present in the Bayou LaCroix, the heelsplitter has 

not been known to occur in this stream system or area. Therefore, a no effect determination is 

recommended.

Crystal Darter - State listed - Endangered

The crystal darter is an elongate, slender species exhibiting a noticeably narrow caudal peduncle. 

Maximum total length is about 150 mm (6 in.). The head is relatively large and flat compared to other

darters. It has four brown saddles on the back which extend downward and forward to the midline 

on each side. The area between the saddles is patterned with dark brown mottling. The sides have a 

row of oblong dark brown blotches. The belly is silvery white and a dark brown stripe extends from 

eye to eye around the snout (Mississippi Museum of Natural Science [MMNS] 2014).

The crystal darter once occurred from Wisconsin east to Ohio and south to Oklahoma, Louisiana, and 

Florida. Its current range is considerably reduced as it is absent from all of Ohio and Indiana. In 

Mississippi, the crystal darter occurs in the Bayou Pierre, Homochitto, Pearl, and Tombigbee 

watersheds. The species formerly occurred in the Pascagoula River watershed of Mississippi as well, 

but has not been collected there since the 1930’s (MMNS 2014).

The crystal darter inhabits clean sand and gravel raceways of larger creeks and rivers. It is usually 

found in water deeper than 60 cm (ca. 2 ft) with moderate to strong current. In the altered main

channel of the Tennessee-Tombigbee Waterway, crystal darters are known to occur over remnant 

gravel patches that are often near tributary confluences (MMNS 2014).

The streams present within the survey corridor have slow to moderate current (flow) and silty mud 

bottoms. This is contrary to the fast-moving, sandy gravel bottoms preferred by the crystal darter. 

No suitable habitat was found within the survey corridor. Therefore, project is not anticipated to 

negatively impact this state listed species.

Ironcolor Shiner - State listed – Endangered

The ironcolor shiner is a small fish with a deep, compressed body that is generally arched and only 

reaches 2.5 inches in length (New York State Department of Environmental Conservation 2017). It 

is colorful, with straw yellow above, a dusky stripe along the back and a silvery-white color below. A 

very prominent black stripe runs along the side, beginning at a black spot at the base of the tail and 

continuing around the snout, covering both lips and its chin. The inside of the mouth is black. Scales 

are darkly outlined except just above the black stripe where a gold-orange streak may be present. 

Breeding males often have an orange-gold body and fins.

The ironcolor shiner is found primarily in lowland streams where stream reaches are characterized 

by abundant aquatic vegetation, open swamp habitat, and/or areas draining densely canopied 

woodlands. It has been observed in deep pool areas of creeks and small rivers, as well as in bodies of 

water where a moderate current exists. They occur in areas with aquatic vegetation, such as 

bladderwort, pondweed and Elodea. Sand seems to be important for spawning.

In Mississippi, this species of shiner has historically occurred within the coastal area of the state in 

the Coastal Rivers, Pascagoula and Pearl River drainage systems and may exist in the survey corridor, 

although none were observed during field investigations. Several creeks and streams are found 

within the survey corridor. Each stream had slow to moderate current and silty mud bottoms. The 

preferred aquatic vegetation was not observed in streams during field reconnaissance. Therefore,

project is not anticipated to negatively impact this state listed species.

Pearl Darter - Federal and State listed – Candidate/Endangered

The pearl darter is a small freshwater fish that measures just two-and-one-half inches long. The pearl 

darter can grow to 2.95 inches with males reaching a larger adult size than females. The body of the 

pearl darter is olive to light brown in color with the sides marked with a series of dark oval to oblong 

blotches and a single black caudal spot located at the base of the caudal fin (MMNS 2014).

Although always believed to be rare, the species was historically found throughout hundreds of river 

miles between Louisiana and Mississippi. Historical distribution included localized sites in the Pearl 

and Pascagoula river drainages, Mississippi and Louisiana (IUNC 2017). Museum collections suggest 

that the pearl darter inhabited the main channels of large Pascagoula drainage tributaries from 

Jackson to Lauderdale counties, Mississippi, including the Pascagoula River, Black Creek, Leaf River, 

Okatoma Creek, Chickasawhay River, Bouie River, and Chunky Creek. Since 1983, pearl darters have 

only been found in scattered sites in the Pascagoula, Chickasawhay, Chunky, Leaf, and Bouie Rivers, 

and Okatoma and Black Creeks. 
Draft Wetlands and Threatened and Endangered Species Report • Threatened and Endangered Species

34 Project No. FRA-0023-00(003)/105494 101000-102000

The species is now considered to be extirpated from the Pearl River drainage in both Mississippi 

and Louisiana (USFWS 2014). It is not known or believed to occur within the two counties that the 

project occurs (Pearl River and Hancock). Therefore, a no effect determination is recommended.

Frecklebelly Madtom - State listed – Endangered

This small species of fish is a member of the catfish family and can reach up to 3.5 inches in length. 

The frecklebelly inhabits stable gravel or rubble riffles and rapids in both the main river channels 

and in their large tributaries. It is intolerant of siltation and sedimentation; therefore, any form of 

habitat alteration is detrimental to its range and succession.

In Mississippi, the frecklebelly inhabits the major tributaries of the Tombigbee River as well as the 

lower portions of the Pearl River drainage. Because the survey corridor is not within the known range 

of the frecklebelly within Mississippi, and because no large tributaries with gravel bottoms were 

observed during the field reconnaissance, it is unlikely the frecklebelly madtom occurs within the 

survey corridor. Therefore, project is not anticipated to negatively impact this state listed species. 

Gulf Sturgeon - Federal and State listed – Threatened/Endangered

The Gulf sturgeon is anadromous and spends the major part of the year in freshwater, migrating to 

saltwater in the fall. Gulf sturgeon return to their natal stream to spawn (Florida Fish and Wildlife 

Conservation Commission 2017). The best river habitat for Gulf sturgeon are long, spring-fed, freeflowing rivers. Steep banks and a hard bottom with an average water temperature of 60 to 72 degrees 

Fahrenheit are also characteristic of rivers that sturgeon inhabit. Sturgeons occupy the river bottom 

downstream of springs where they seek thermal refuge during hot summer days. Movement from 

the gulf and up-river movement generally occurs between February and April, while down-river 

movement occurs between September and November. Its diet consists of bottom-dwelling 

organisms; amphipods, isopods, crustaceans, and marine worms.

Historically, the Gulf sturgeon occurred from the Mississippi River to Charlotte Harbor, Florida. 

Today its current range is limited from the Suwannee River in Florida to the Pearl River in Mississippi 

and Louisiana.

River systems with viable populations include the Pearl, Pascagoula, Escambia, Yellow, 

Choctawhatchee Apalachicola, and Swanee rivers. The Gulf sturgeon rarely migrates far into the 

Mississippi River due to a natural lack of spawning habitat.

The total number of mature individual Gulf sturgeon is unknown, but scientists estimate that the 

Suwannee River supports about 7,650 adults. Estimates for Apalachicola River in Florida and 

Mississippi’s Pascagoula and Pearl rivers range between 50 and 350 mature sturgeon.

No suitable habitat for the sturgeon occurs within the project’s survey corridor. No large river or 

streams with steep banks are present. Sturgeon in Mississippi are limited to the ideal habitat of 

stretches of the Pearl River. Therefore, a no effect determination is recommended. 

Smalltooth Sawfish – Federal - Endangered

Smalltooth sawfish inhabit shallow coastal waters of tropical seas and estuaries throughout the 

world. They are usually found in shallow waters (less than 32 feet) very close to shore over muddy 
Draft Wetlands and Threatened and Endangered Species Report • Threatened and Endangered Species

35 Project No. FRA-0023-00(003)/105494 101000-102000

and sandy bottoms (National Oceanic and Atmospheric Administration [NOAA] 2015). They are often 

found in sheltered bays, on shallow banks, and in estuaries or river mouths. They prefer warmer 

water temperature of 71-82°F. They are known to ascend inland in river systems and have been 

shown to have a salinity preference of 18-24 parts per thousand. They reach 18-25 feet in length and 

have a lifespan of 25-30 years. They can weigh up to 770 pounds and feed mostly on fish and 

crustaceans. 

Smalltooth sawfish prefer saline or brackish water. The project area is located inland and does not 

contain brackish or estuarine waters. There is no suitable habitat within the project’s survey 

corridor. Therefore, a no effect determination is recommended.

Louisiana quillwort – Federal - Endangered

The Louisiana quillwort is a small, semi-aquatic, facultative evergreen plant with spirally-arranged 

leaves (sporophylls) arising from a globose, two-lobed corm. The pliant, hollow leaves are 

transversely septate and measure 0.12 inch wide and up to 16.0 inches long. These plants are 

valuable indicators of stream health. To date, 8 populations occur in Louisiana, 3 populations in 

Alabama, and 30 populations in Mississippi (TNC 2017). It was not until 1996 that Louisiana 

quillwort plants were verified in Mississippi. Most Mississippi colonies of quillwort are found in the 

DeSoto Ranger District of the DeSoto National Forest (Forrest, Perry, Stone, Harrison, and Jackson 

counties) with a smaller cluster of sites in North-Central Hancock County. One colony is known from 

Pearl River County (MMNS 2014). 

Louisiana quillworts grow in mineral soil, usually light grey in color, in bottomlands that are 

periodically washed free of leaves and debris. Overstory trees are typically laurel oak, red maple, 

tuliptree, and swamp tupelo. Pine trees are only occasionally observed, but they may have been more 

common, as large old pine stumps are frequently observed around quillwort populations.

The Louisiana quillwort was listed as an endangered species by the USFWS in 1992 before 

populations were observed in Mississippi. Although the majority of known Mississippi colonies are 

found on public land, various land uses, including certain silviculture activities, military training, and 

some recreational activities, as well as natural alterations arising from impoundment of streams, may 

contribute to adverse impacts on quillwort habitat. Activities which negatively affect hydrology, 

water quality, and/or substrate stability could threaten population persistence in its habitat. 

Some suitable habitat for the quillwort is present within the survey corridor. However, the health of 

the streams segments present were in decline due to silviculture practices, pollution, and debris

There are two ephemeral streams, six intermittent streams, and five perennial streams within the 

project corridor. Most of the project crossings (Streams #1-9) occur at existing road and railroad 

culverts and do not represent placement of structures in undisturbed areas. Several of these crossing 

locations are above long sections of concrete culverts such as the Interstate 59 crossings of Alligator 

Creek. Therefore, potential impacts to stream habitat that could potentially contain Louisiana 

quillwort are not anticipated at these locations as they simply will be modifications of existing 

culverts. Thus, impacts to Louisiana quillwort are extremely unlikely to occur in these areas. 

There are four new crossings of perennial streams along the project corridor where some impacts to 

stream habitat could occur. Three of these crossings (Streams #10, 11, and 12) are directly adjacent 
Draft Wetlands and Threatened and Endangered Species Report • Threatened and Endangered Species

36 Project No. FRA-0023-00(003)/105494 101000-102000

to existing road box culverts or utility easements which have had some level of prior disturbance 

associated with previous construction activities. Only one (Stream # 13; Bayou LaCroix) of these four 

new crossings is in an area not directly adjacent to a utility easement or existing culvert. However,

Bayou LaCroix has be severely impacted by conversion of forest to cattle pasture in the area of the 

proposed crossing. Approximately 50 acres of the riparian zone of this stream has been converted 

to pasture. Thus, the partially open canopy and disturbance from cattle operations has resulted in 

suboptimal to poor habitat for Louisiana quillwort in this perennial stream. It is unlikely the quillwort 

inhabits these streams and no quillwort were observed during field observations. Additionally, given 

the small potential footprint of new disturbance (eg, new culverts or bridges) on perennial streams, 

impacts to the Louisiana quillwort are extremely unlikely. Therefore, a determination of may affect, 

not likely to adversely affect is recommended for this species.

Eastern Indigo Snake - Federal and State listed – Threatened/Endangered

The eastern indigo snake (Drymarchon couperi) is a non-venomous, black snake. It is the longest 

snake native to the United States, ranging in size from 60 to 84 inches, and is entirely shiny bluishblack color, including the belly (Savannah River Ecology Laboratory [SREL] 2017a). The chin and 

sides of the head are usually colored reddish or orange-brown. Juvenile indigo snakes look very 

similar to adults, but have much more red on their heads. Indigo snakes are sexually dimorphic, with 

males growing to larger lengths than females.

Eastern indigo snakes are restricted to Florida and southern areas of Georgia, Alabama, and 

Mississippi. Until relatively recently, all indigo snakes in the U.S. were considered to be the same 

species, D. corais (SREL 2017a).

In the southeast, indigo snakes are restricted to areas with dry sand ridges and pine-oak sandhills 

(uplands), dominated by pines (primarily longleaf) and oaks. Gopher tortoises usually inhabit the 

areas where the eastern indigo snake is found. These snakes use gopher tortoise burrows as shelter 

during the winter and during the warmer months for nesting and refuge from intense summer heat. 

During the active season, indigo snakes may move long distances and often forage along wetland 

margins.

Indigo snakes are active strictly by day. During the summer they prefer wetland edges where prey is 

abundant, but move to drier habitats in the winter. Indigo snakes breed in the winter and are more 

active in cold weather than most other snakes. When cornered, they may flatten their heads, hiss and 

vibrate their tails, which produces a rattling sound. Despite these intimidating acts, the indigo snake 

rarely bites. Indigo snakes regularly feed on mammals, birds, frogs and other snakes, including 

rattlesnakes and cottonmouths. Also, these snakes will occasionally feed on young gopher tortoises.

In the past, periodic growing season fires created excellent upland habitat for the gopher tortoise, 

the presence of which is important to the Indigo snake in Mississippi. In recent years, fires have been 

excluded from formerly suitable habitat and burning is primarily performed in the dormant season; 

this sort of burning does not effectively control proliferation of hardwoods and brush. In parts of its 

range, this species has been adversely affected by the “gassing” of gopher tortoise burrows, a practice 

illegal in Mississippi. The last specimen actually collected in Mississippi was taken in 1939, and there 
Draft Wetlands and Threatened and Endangered Species Report • Threatened and Endangered Species

37 Project No. FRA-0023-00(003)/105494 101000-102000

have been no verified observations of natural populations of the Indigo snake in Mississippi since the 

1950s.7

Suitable habitat exists for the eastern indigo snake occurring in the survey corridor, particularly 

along wetland edges and in the summer months. They usually prefer pine oak sandhills usually 

inhabited by gopher tortoises. Due to the low probability of gopher tortoises in the majority of the 

survey corridor, in which the eastern indigo snake uses the tortoise burrows for shelter during 

winter, it is unlikely to inhabit the entire survey corridor, but may be restricted to the wetland areas 

where prey is abundant. However, due to lack of observation of the species in Mississippi since the 

1950s, it may be extirpated. Therefore, a determination of may affect, not likely to adversely affect is 

recommended for this species.

Southern Hognose Snake - State listed – Endangered

Southern hognose snakes are fairly small, heavy-bodied snakes that reach about 24 inches in length

(SREL 2017b). These snakes are easily distinguished from most snakes in the region by their pointed, 

upturned snouts. Unlike eastern hognose snakes (Heterodon platirhinos), which occur in several color 

patterns, southern hognose snakes are always gray, tan, or reddish in color with a series of dark 

brown blotches down the center of the back and alternating smaller blotches along the sides. They 

are never solid black like the eastern hognose. Although generally less elaborate than those of the 

eastern hognose, southern hognose snakes also often put on threat displays (including neck 

spreading, hissing, and playing) when confronted by a predator. Female southern hognose snakes 

are larger than males and the young resemble miniature adults.

Southern hognose snakes were historically found in the Coastal Plain of the eastern United States 

from southern North Carolina to southern Mississippi and in most parts of Florida. However, this 

species has declined in recent years and is now only found in scattered locations in South Carolina, 

North Carolina, Georgia, and Florida. Although both species of hognose snake in the southeast prefer 

sandy areas, southern hognose snakes are found almost exclusively in sandhill, pine flatwood and 

coastal dune habitats, and in the sand ridges of central Florida (SREL 2017b).

Southern hognose snakes are active strictly by day and are often seen on warm mornings in the 

spring and fall. They are highly fossorial (living underground) and are most often encountered 

crossing roads that pass through sandy habitats (SREL 2017b).

Hognose snakes feed almost exclusively on toads, although they will occasionally consume other 

prey. They seem to be immune to poisons produced by toads, and are equipped with enlarged teeth 

(called rear fangs) in the back of their mouths that are used to puncture inflated toads so that they 

may be more easily swallowed. Female southern hognose snakes lay 6 to 14 eggs in sandy soil or logs 

in the early summer. The eggs hatch in September or October (SREL 2017b).

Few sandy uplands are found in the survey corridor, which is primarily made up of dense forested 

wetlands with saturated soils. Studies show that the southern hognose snake may no longer even 

inhabit Mississippi, but instead is restricted to the Carolinas, Georgia, and Florida. If in Mississippi, it

is most likely to occur in northern counties with sandy, pine flatwoods. Therefore, project is not 

anticipated to negatively impact this state listed species.

Black Pine Snake - Federal and State listed – Threatened/Endangered

The black pine snake is a large dark brown to black snake that prefers to inhabit mature, longleaf 

pine forests, similar to the gopher tortoise, with sandy soil, an open canopy, moderately firesuppressed midstory and a thick grassy understory (MMNS 2014). Recent studies co-sponsored by 

the Mississippi Natural Heritage Program have shown that the black pine snake is usually found in 

rotting pine stumps and are located underground two-thirds of the time (MMNS 2014). It is 

considered critically imperiled and in decline along with its preferred habitat of longleaf pine forests 

due to timbering and conversion to agriculture.

Although the black pine snake has been known to occur in 14 counties within southern Mississippi, 

(excluding Hancock County) the species is now extremely rare over most of the historic range and 

has been extirpated from Louisiana and Lauderdale County, Mississippi. Its current range includes 

Pearl River County but does not include Hancock County (MMNS 2014). It is still relatively common 

within DeSoto National Forest in Mississippi. A recent study commissioned by USFWS found that 31 

percent of historical black pine snake population segments have been extirpated and that another 26 

percent are in serious jeopardy; the main reason for the decline being habitat destruction and 

fragmentation. In recent years, fires (controlled burning) has been excluded from some formerly 

suitable habitats in Mississippi, resulting in a dense understory of hardwoods and shrubs that 

prevent sunlight from reaching the forest floor, shading out food sources of the black pine snake

(MMNS 2014).

Within Pearl River County where the black pine snake could potentially occur, the proposed project 

will occur on existing rail line. This includes potential maintenance activities on the railroad berm 

and the replacement of the existing rail with new rails. Therefore, significant expansion of the 

railroad foot print will not occur and there will not be extensive impacts to the surrounding habitat. 

Furthermore, habitat quality for the black pine snake adjacent to the project corridor in Pearl River

County is poor because of the high degree of fragmentation and general exclusion of fire necessary 

to develop the long leaf pine ecosystems with an open canopy and grassy understory. Literature also 

states that the black pine snake may be found within stream or river corridors and near pitcher plant 

bogs, which were present within the survey corridor. However, the proposed project will not create 

any new crossings of streams in Pearl River County. All crossings will be at existing culverts. Thus, 

impacts to stream and wetland habitat that could potentially be used by the black pine snake will be 

extremely small, if any. Therefore, a determination of no effect is recommended for this species.

Rainbow Snake - State listed – Endangered

The rainbow snake is a large (up to 66 inches), non-venomous, highly aquatic snake that is seldom 

seen because of its secretive habits (SREL 2017c). Adults have three red stripes running down a 

glossy black back. The belly is red or pink with two or three rows of black spots. Yellowish coloration 

is often present on the head and sides. They have small dark eyes, smooth shiny scales, and a pointed 

tail tip. Male rainbow snakes are smaller than females but have relatively longer and thicker tails. 

Young rainbow snakes resemble adults but generally lack any yellow coloration.
Draft Wetlands and Threatened and Endangered Species Report • Threatened and Endangered Species

39 Project No. FRA-0023-00(003)/105494 101000-102000

Rainbow snakes are found in the Coastal Plain of the southern United States from southern Virginia 

to eastern Louisiana. In Mississippi, it has been recorded in Forrest, Jackson, Hancock, Lamar, Pearl 

River, and Copiah counties. Rainbow snakes are found in a variety of aquatic habitats but are most 

common in cypress swamps and flowing-water habitats such as blackwater creeks, streams, and 

rivers, with soils which are sandy enough to allow it to burrow. In coastal areas, rainbow snakes can 

be found in tidal or even brackish water. Although highly aquatic, rainbow snakes occasionally move 

overland and are sometimes found far from water.

Rainbow snakes are highly aquatic and spend most of their lives hidden amongst aquatic vegetation 

and debris. Unlike water snakes, rainbow snakes seldom bask out of the water, preferring to remain 

burrowed into vegetation or soil, and thus are seldom encountered anywhere in its range, implying 

that it is a relatively rare species. However, due to its secretive nature, may be much more common 

than it appears. Rainbow snakes are perhaps most frequently encountered crossing roads adjacent 

to aquatic habitats, particularly on rainy summer nights. When captured, rainbow snakes do not bite.

The wetlands and other aquatic habitats in the survey corridor provide suitable habitat for the 

rainbow snake, and it has been recorded in Hancock County, Mississippi. It is most likely to be found 

in the areas where hardwoods, cypress swamp, and emergent vegetation occurs, providing the ideal 

vegetative cover and habitat for both dwelling and foraging. Therefore, the project may adversely 

impact this state listed species.

Gopher Tortoise - Federal and State listed – Threatened/Endangered

The gopher tortoise is a large (shell 5.9 to 14.6 inches long), dark-brown to grayish-black terrestrial 

turtle, with shovel-like forefeet, and a gular projection beneath the head on the yellowish, hingeless 

plastron or undershell (Ernst and Barbour 1972). 

Gopher tortoises, or “gophers” as they are commonly called, live in extensive subterranean burrows 

in dry upland habitats (Gopher Tortoise Council 2017). The habitats where gopher tortoises are 

found include longleaf pine sandhills, xeric oak hammocks, scrub, pine flatwoods, dry prairies, and 

coastal dunes. Tortoises can also live in manmade environments, such as pastures, old fields, and 

grassy roadsides. To be suitable for gopher tortoises, the habitat must have well-drained sandy soils 

for digging burrows, herbaceous food plants, and open sunny areas for nesting and basking. Human 

activities eliminated gopher tortoises from a significant portion of their historic range, but they still 

occur in Alabama, South Carolina, Louisiana, Mississippi and Georgia, with the majority of the 

remaining population in Florida.

Due to the saturated soil conditions unsuitable for burrowing, the lack of suitable herbaceous plants 

for foraging, the dense canopy that covers most of the pine plantation and shrub area of the survey 

corridor, it is unlikely the gopher tortoise occurs in the survey corridor. The pine flatwood areas are 

heavily modified due to logging and other silviculture activities, have poorly drained saturated soils

with a high water table, and have a dense canopy that limits an herbaceous layer for available food 

and open areas for basking. Therefore, a no effect determination is recommended for this species.

Ringed Map Turtle - Federal and State listed – Threatened/Endangered

The ringed map turtle is small. Each shield of its upper shell (carapace) has a yellow ring bordered 

inside and outside with dark olive-brown; its undershell (plastron) is yellow. The head has a large 
Draft Wetlands and Threatened and Endangered Species Report • Threatened and Endangered Species

40 Project No. FRA-0023-00(003)/105494 101000-102000

yellow spot behind the eye, two yellow stripes from the orbit backwards, and a characteristic yellow 

stripe covering the whole lower jaw (Cagle, 1953). Males grow to 4 inches and females to 7 inches in 

plastron length.

The ringed map turtle is native to the Pearl River watershed of Mississippi and Louisiana. It occurs 

mainly in the Pearl River and its largest tributary, the Bogue Chitto River. It occasionally appears in 

some of the smaller tributaries (The Turtle Room 2017). It is not found in the lower, tidally influenced 

sections of the lower West Pearl River and Pearl River drainage system. The ringed map turtle prefers 

wide, sand- or clay-bottomed rivers with strong currents and adjacent white sand beaches. An 

abundance of basking sites in the form of brush, logs and debris is also an important part of its habitat 

and on which it can safely bask, protected from predation and suitable nesting habitat (large, high 

sandbars adjacent to a river). These habitat features are threatened by modification conducted for 

flood control and sand and gravel mining. 

Studies have shown stable populations of the ringed map turtle in northern portions of the Pearl 

River near reservoir sites. The ringed map turtle is not known to occur within the survey corridor, 

which lacks suitable foraging and nesting habitat. Therefore, a no effect determination is 

recommended for this species.

Sea Turtles

Four of the world’s seven sea turtle species are protected under the ESA, by the NMFS when they 

occur in the Gulf of Mexico coastal waters and in U.S. territorial waters, and by USFWS when they 

occur on land (for example, during nesting). These species include the loggerhead, leatherback, 

Atlantic hawksbill, and Kemp’s ridley and are described below. It is rare that these species inhabit 

inland water in coastal Mississippi.

Kemp’s Ridley Sea Turtle - Federal and State listed – Endangered/Endangered

The Kemp's ridley turtle is the smallest of the sea turtles, with adults reaching about 2 feet in length 

and weighing up to 100 pounds (USFWS 2016a). The adult Kemp's ridley has an oval carapace that 

is almost as wide as it is long and is usually olive-gray in color. The carapace has five pairs of costal 

scutes (plates). Four inframarginal scutes are located in each bridge adjoining the plastron to the 

carapace, each of which is perforated by a pore. The head has two pairs of prefrontal scales (USFWS 

2016a). The Kemp's ridley has a triangular-shaped head with a somewhat hooked beak with large 

crushing surfaces. This turtle is a shallow-water benthic feeder, with a diet consisting primarily of 

crabs. Preferred habitat consists of warm, isolated waters along the coast such as bays, bayous, tidal 

rivers, and offshore waters and estuaries during non-nesting and sandy coastal beaches during 

nesting 

No suitable foraging or nesting habitat occurs within the survey corridor. Therefore, a no effect 

determination is recommended for this species.

Leatherback Sea Turtle - Federal and State listed – Endangered/Endangered

The leatherback is the largest, deepest diving, and most migratory and wide ranging of all sea turtles. 

The adult leatherback can reach 4 to 8 feet in length (USFWS 2016a). Its shell is composed of a mosaic 

of small bones covered by firm, rubbery skin with seven longitudinal ridges or keels. The skin is 
Draft Wetlands and Threatened and Endangered Species Report • Threatened and Endangered Species

41 Project No. FRA-0023-00(003)/105494 101000-102000

predominantly black with varying degrees of pale spotting; including a notable pink spot on the 

dorsal surface of the head in adults. A tooth-like cusp is located on each side of the gray upper jaw; 

the lower jaw is hooked anteriorly. The paddle-like clawless limbs are black with white margins and 

pale spotting.

The preferred habitat of the leatherback is primarily very deep, open tropical and subtropical oceans 

that allow for deep diving No suitable habitat occurs within the survey corridor. Therefore, a no effect 

determination is recommended for this species.

Loggerhead Sea Turtle - Federal and State listed – Threatened/Endangered

Loggerheads were named for their relatively large heads, which support powerful jaws and enable 

them to feed on hard-shelled prey, such as whelks and conch (USFWS 2016a). The carapace (top 

shell) is slightly heart-shaped and reddish-brown in adults and sub-adults, while the plastron 

(bottom shell) is generally a pale yellowish color. The neck and flippers are usually dull brown to 

reddish brown on top and medium to pale yellow on the sides and bottom. Mean straight carapace 

length of adults in the southeastern U.S. is approximately 36 inches; corresponding weight is about 

250 pounds (USFWS 2016a). 

Preferred loggerhead habitat includes open deep water and marine open shallow water, especially 

with submerged seagrass beds, salt marshes, bays, tidal passes, and coastal dunes. This species is also 

known to inhabit warm water bodies over the continental shelf and regularly to enter marshes, 

estuaries and coastal rivers that contain aquatic plants, crustaceans, mollusks, jellyfish, squid, sea 

urchins and fish for forage.

No suitable habitat occurs within the survey corridor. Therefore, a no effect determination is 

recommended for this species.

Hawksbill Sea Turtle - Federal and State listed – Endangered/Endangered

The hawksbill sea turtle is one of seven species of sea turtles found throughout the world (USFWS 

2016a). One of the smaller sea turtles, it has overlapping scutes (plates) that are thicker than those 

of other sea turtles. Adults range in size from 30 to 36 inches carapace length, and weigh 100 to 200 

pounds. Its carapace (upper shell) is an attractive dark brown with faint yellow streaks and blotches 

and a yellow plastron (under shell). The name "hawksbill" refers to the turtle's prominent hooked 

beak (USFWS 2016a). The hawksbill turtles in the Gulf of Mexico are mainly found in Mexico, Texas, 

and Florida, with only isolated occurrences in other Gulf states. The hawksbill’s preferred habitat 

consists of warm, shallow water habitats (usually less than 65 ft in depth) such as bays, shoals, and 

coral reefs located worldwide. Seagrass beds, estuaries, mainland beaches and islands are typically 

preferred for nesting. Thus, the hawksbill is not likely to occur in the survey corridor due to lack of

suitable habitat. Therefore, a no effect determination is recommended for this species.

Peregrine Falcon - State listed – Endangered

The word "peregrine" means "wanderer" or "pilgrim," and peregrine falcons occur all over the world

(Cornell Lab of Ornithology [CLO] 2017). In North America, they breed in open landscapes with cliffs 

(or skyscrapers) for nest sites. They can be found nesting at elevations up to about 12,000 feet, as 

well as along rivers and coastlines or in cities. In migration and winter, peregrine falcons can be found 
Draft Wetlands and Threatened and Endangered Species Report • Threatened and Endangered Species

42 Project No. FRA-0023-00(003)/105494 101000-102000

in nearly any open habitat, but with a greater likelihood along barrier islands, mudflats, coastlines, 

lake edges, and mountain chains (CLO 2017a).

Peregrine falcons eat mostly birds, of an enormous variety. They have been observed killing birds as 

large as a sandhill crane, as small as a hummingbird, and as elusive as a white-throated swift. Typical 

prey include shorebirds, ptarmigan, ducks, grebes, gulls, storm-petrels, pigeons, and songbirds,

including jays, thrushes, longspurs, buntings, larks, waxwings, and starlings. Peregrine falcons also 

eat substantial numbers of bats. They occasionally pirate prey, including fish and rodents, from other 

raptors (CLO 2017).

Typically, peregrine falcons nest on cliffs from about 25 to 1,300 feet high (and higher, including on 

the rim of the Grand Canyon). On these cliffs they choose a ledge that is typically around a third of 

the way down the cliff face. In places without cliffs, peregrines may use abandoned common raven, 

bald eagle, osprey, red-tailed hawk, or cormorant nests. 

The survey corridor lacks ideal open habitat for the peregrine falcon, and does not provide suitable 

foraging habitat. The peregrine falcon is not likely to occur within the densely forested survey 

corridor. No sightings of the falcon were recorded during field reconnaissance. Therefore, project is 

not anticipated to negatively impact this state listed species.

Piping Plover - Federal and State listed – Endangered & Threatened/Endangered

These small, stocky migratory shorebirds have a sand-colored upper body, a white underside, and 

orange legs (USFWS 2016a). During the breeding season, adults have a black forehead, a black breast 

band, and an orange bill. Piping plovers use wide, flat, open, sandy beaches with very little grass or 

other vegetation. Nesting territories often include small creeks or wetlands. The plovers eat insects, 

spiders, and crustaceans. In the fall, plovers migrate south and winter along the coast of the Gulf of 

Mexico or other southern locations. 

The wetlands in the survey corridor consist mostly of densely vegetated pine flatwoods with no 

surrounding beaches. The existing wetlands are also not ideal for piping plover foraging or as a 

stopover site. Piping plovers do not nest in inland Mississippi, but winter along coastal beaches and 

barrier islands. The survey corridor is located too far inland from the preferred coastal habitat of the 

piping plover. Therefore, a no effect determination is recommended for this species.

Southeastern Snowy Plover - State listed – Endangered

The snowy plover can be found across North and South America, Eurasia, and Africa (CLO 2017b). In 

North America, it is restricted to the Gulf and Pacific coasts of the United States. For habitat, the 

snowy plover prefers barren to sparsely vegetated sand beaches, dry salt flats in lagoons, dredge 

spoils deposited on beach or dune habitat, levees and flats at salt-evaporation ponds, river bars, along 

alkaline or saline lakes, reservoirs, and ponds. A natural or scraped depression on dry ground usually 

lined with pebbles, shell fragments, fish bones, mud chips, vegetation fragments, or invertebrate 

skeletons is preferred for nesting (USFWS 2016a).

The project survey corridor is primarily inland forested wetlands of pine and hardwoods, with scrub 

shrub understory. The area contains no suitable nesting or foraging coastal habitat preferred by the 
Draft Wetlands and Threatened and Endangered Species Report • Threatened and Endangered Species

43 Project No. FRA-0023-00(003)/105494 101000-102000

snowy plover. Therefore, it is unlikely the snowy plover inhabits the area. Therefore, project is not 

anticipated to negatively impact this state listed species. 

Red Knot - Federal listed Threatened

At 9 to 10 inches long, the red knot is a large, bulky sandpiper with a short, straight, black bill (USFWS 

2016a). During the breeding season, the legs are dark brown to black, and the breast and belly are a 

characteristic russet color that ranges from salmon red to brick red. Males are generally brighter 

shades of red, with a more distinct line through the eye. When not breeding, both sexes look alike—

plain gray above and dirty white below with faint, dark streaking. Red knots feed on invertebrates, 

especially small clams, mussels, and snails, but also crustaceans, marine worms, and horseshoe crab 

eggs. On the breeding grounds knots mainly eat insects. The primary wintering areas for the red knot 

include the southern tip of South America, northern Brazil, the Caribbean, and the southeastern and 

Gulf coasts of the U.S. (USFWS 2016a).

The red knot can be found in Mississippi during the winter months (October through March). Here, 

they forage on coastal sandy beaches, tidal mud flats, salt marshes, oyster reefs, and exposed bay 

bottoms. Red knots roost on high sand flats, reefs, and other areas protected from high tides. 

The survey corridor consists primarily of forested wetlands and lack the sandy coastal habitat

preferred by red knots. The survey corridor also lacks an important food source for red knots 

(coquina clams), that are common to Gulf beaches. Due to lack of suitable habitat and food source, 

and because of no known occurrences of the red knot in the inland survey corridor, the project is not 

anticipated to impact the red knot. Therefore, a no effect determination is recommended for this 

species.

Red-Cockaded Woodpecker - Federal and State listed – Endangered/Endangered

About the size of the common cardinal, the red-cockaded woodpecker is approximately 7 inches long, 

with a wingspan of about 15 inches. Its back is barred with black and white horizontal stripes. The 

red-cockaded woodpecker's most distinguishing feature is a black cap and nape that encircle large 

white cheek patches (Nemours Wildlife Foundation 2014). Rarely visible, except perhaps during the 

breeding season and periods of territorial defense, the male has a small red streak on each side of its 

black cap called a cockade, hence its name. Female red-cockaded woodpeckers lack the red cockade. 

Juvenile males have a red 'patch' in the center of their black crown. This patch disappears during the 

fall of their first year at which time their 'red-cockades' appear. 

The diet of red-cockaded woodpeckers consists mostly of insects in the egg, larvae, and adult stages. 

These include beetles, ants, roaches, spiders and other insects found in or on pine trees. Fruits and 

seeds make up a small portion of the overall diet. Large, older trees are preferred for foraging. In 

general, males forage on the limbs and upper trunk while females forage on the trunk below the 

crown. 

The red-cockaded woodpecker makes its home in mature pine forests (60+ years old). Longleaf pines 

are most commonly preferred, but other species of southern pine are also acceptable. While other 

woodpeckers bore out cavities in dead trees where the wood is rotten and soft, the red-cockaded 

woodpecker is the only one that excavates cavities exclusively in living pine trees. Cavities are 

excavated in mature pines, generally over 80 years old. The older pines favored by the red-cockaded 
Draft Wetlands and Threatened and Endangered Species Report • Threatened and Endangered Species

44 Project No. FRA-0023-00(003)/105494 101000-102000

woodpecker often suffer from a fungus called red heart disease, which attacks the center of the trunk, 

causing the inner wood, the heartwood, to become soft. Cavity excavation takes from one to six years.

In Mississippi, the red-cockaded woodpecker mainly occurs in the southern two-thirds of the state. 

It has not been found in the Delta and only sporadically occurs in northern counties. Although 

historically the red-cockaded woodpecker was found to occur in Pearl River and Hancock Counties 

where the proposed project occurs, recent data from USFWS indicate that this species is not 

distributed in this area (USFWS 2002). However, USFWS data indicate that this species is present in 

the adjacent Harrison County, MS and St. Tammany Parish, LA. Thus, it is unlikely that the redcockaded woodpecker would nest within the survey corridor given the lack of mature undisturbed 

pine stands. The pine plantations in the southeast are typically clearcut within 35 years of initial 

planting (University of Arkansas 2014). Pine plantations within and directly adjacent to the survey 

corridor are heavily managed and appear to be clearcut on a rotation of less than 35 years based on 

aerial photographs. Therefore, the presence of suitable nesting habitat (pine tree stand greater than 

60 years old) within 0.5 miles of the survey corridor is highly unlikely. Many of the pine plantations 

within the survey corridor are less than 30 years old. While some suitable foraging habitat may be 

present within the survey corridor, this habitat is unlikely to be used by red cockaded woodpecker 

because of the low probability of suitable nesting habitat occurring within 0.5 miles of the survey 

corridor. Thus, impacts to potential suitable foraging habitat are not expected to impact this species. 

Therefore, a determination of may affect, not likely to adversely affect is recommended for this 

species.

Wood Stork - Federal and State listed – Threatened/Endangered

Wood storks are large, long-legged wading birds, about 50 inches tall, with a wingspan of 60 to 65 

inches. The plumage is white except for black primaries and secondaries, and a short black tail. The 

head and neck are largely unfeathered and dark gray in color. The bill is black, thick at the base, and 

slightly decurved. Immature birds are dingy gray and have a yellowish bill. 

Nesting has been restricted to Florida, Georgia, and South Carolina; however, they may have formerly 

bred in most of the southeastern United States and Texas (USFWS 2016a). A second distinct, nonendangered population of wood storks breeds from Mexico to northern Argentina.

Wood storks from both populations move northward after breeding, with birds from the 

southeastern United States population moving as far north as North Carolina on the Atlantic coast 

and into Alabama and eastern Mississippi along the Gulf coast, and storks from Mexico moving up 

into Texas and Louisiana and as far north as Arkansas and Tennessee along the Mississippi River 

Valley. Occasional sightings are known from all states along and east of the Mississippi River, and 

sporadic sightings in some states west of the Mississippi and in Ontario.

Storks are birds of freshwater and estuarine wetlands, including ponds, bayheads, flooded pastures, 

oxbow lakes, and ditches. They nest primarily in cypress or mangrove swamps. They feed in 

freshwater marshes, narrow tidal creeks, or flooded tidal pools. Particularly attractive feeding sites 

are depressions in marshes or swamps where fish become concentrated during periods of falling 

water levels. 
Draft Wetlands and Threatened and Endangered Species Report • Threatened and Endangered Species

45 Project No. FRA-0023-00(003)/105494 101000-102000

The Wood Stork is listed as an endangered species by USFWS in only Florida, Georgia, Alabama, and 

South Carolina because at the time of listing, that was the range of the U.S. breeding population. Birds 

from Mexican and Guatemalan breeding populations can be found in the U.S. as well, but these birds 

are not considered endangered. It is assumed birds found in Mississippi came from the non-listed 

population. 

In Mississippi, storks are found on the western edge of the state in those areas bordering the 

Mississippi River. Nesting wood storks have not been confirmed in Mississippi, although a report of 

possible nesting was made along the Mississippi River north of Vicksburg. Although storks are not 

known to nest in Mississippi, the forested wetland habitat, freshwater streams, and location of the 

project area may provide suitable stopover and foraging habitat. Therefore, a determination of may 

affect, not likely to adversely affect is recommended for this species.

Brown Pelican - Federal and State listed – Delisted/Endangered

The brown pelican is a wading bird with an oversized bill, sinuous neck, and big, dark body (CLO 

2017c). They measure up to 54 inches long and weigh 8 to 10 pounds. Brown pelicans live year-round 

in estuaries and coastal marine habitats along both the east and west coasts. They breed between 

Maryland and Venezuela, and between southern California and southern Ecuador—often wandering 

farther north after breeding as far as British Columbia or New York. On the Atlantic and Gulf coasts 

they breed mostly on barrier islands, natural islands in estuaries, and islands made of refuse from 

dredging, but in Florida and southern Louisiana they primarily use mangrove islets (CLO 2017c). 

When not feeding or nesting, they rest on sandbars, pilings, jetties, breakwaters, mangrove islets, and 

offshore rocks.

Brown pelicans mostly eat small fish that form schools near the surface of the water—including 

menhaden, mullet, anchovies, herring, and sailfin mollies. A foraging pelican spots a fish from the air 

and dives headfirst from as high as 65 feet over the ocean, tucking and twisting to the left to protect 

its trachea and esophagus from the impact. As it plunges into the water, its throat pouch expands to 

trap the fish, filling with up to 2.6 gallons of water. Pelicans usually feed above estuaries and shallow 

ocean waters within 12 miles of shore. They occasionally feed by sitting on the surface and seizing 

prey with their bills, like other pelican species, usually when a dense school of fish is close to the 

surface and the water is too shallow and muddy to plunge. They also steal food from other seabirds, 

scavenge dead animals, and eat invertebrates such as prawns.

Ground nests range from depressions lined with grass to bulky structures of sticks, grass, and 

seaweed, while tree nests are usually well-built platforms of sticks lined with grass or leaves. The 

female builds the nest in 7–10 days as the male gathers progressively smaller sticks for her. She 

pushes sticks together with her bill and then forms a nest cup by pressing with her feet and body. 

The male brings new material for the female to add throughout incubation, and he may rearrange the 

nest while inside. Nests measure up to 30 inches across and 9 inches high on the outside, with an 

interior space up to 12 inches across and 4 inches deep.

In the 1960s, brown pelicans nearly disappeared from the Gulf Coast. Brown pelicans are now 

uncommon, regular visitors to the Mississippi coast and more sightings are reported each year. 
Draft Wetlands and Threatened and Endangered Species Report • Threatened and Endangered Species

46 Project No. FRA-0023-00(003)/105494 101000-102000

The survey corridor is located inland from any large coastal body of water pelicans would need for 

access to their food source and nesting. No pelicans were observed during field reconnaissance and 

no suitable habitat is found within the survey corridor. Therefore, project is not anticipated to 

negatively impact this state listed species.

Black Bear - Federal and State listed – Delisted/Endangered

The American black bear is the smallest of the three bears species found in North America, and is

found only in North America. Black bears have short, non-retractable claws that give them an 

excellent tree-climbing ability. American black bears are omnivorous, eating plants, fruits, nuts, 

insects, honey, salmon, small mammals, and carrion. In northern regions, they eat spawning salmon.

It is estimated that at least 600,000 black bears live in North America. In the United States, the 

population is estimated to be over 300,000 individuals. According to historical accounts, black bears 

once lived throughout Mississippi. Today, black bears are primarily found in counties along the 

Mississippi, Lower Pearl, and Pascagoula watersheds. 

Mississippi is home to two subspecies of black bear—the Louisiana black bear (Ursus americanus 

luteolus) and Florida black bear (Ursus americanus floridanus) are unique subspecies with small 

populations. The Louisiana black bear was recently delisted; the Florida black bear is estimated to 

number 3,000.

Most of the bears in the state of Mississippi are found along the drainages of major rivers such as the 

Mississippi, Pearl, and Pascagoula, although bears can and have been known to show up just about 

anywhere. Most of the bears found in the state are believed to be transient males that have wandered 

across state lines. They are the dispersing products of breeding populations of bears that border the

state in Arkansas, Louisiana, and Alabama. Black bears were listed as endangered in Mississippi in 

1984. The Louisiana black bear, which is the subspecies that occurs in the southern half of the state, 

was listed as federally threatened in 1992. However, as noted above, it has recently been delisted. 

Only small differences in skull size and shape exist between the American black bear in north 

Mississippi and the Louisiana black bear found in the south. Mississippi Department of Wildlife, 

Fisheries, and Parks’ (MDWFP) biologists currently estimate the Mississippi bear population at less 

than 150 bears in the entire state. 

Suitable habitat occurs in the survey corridor, primarily in hardwood forested areas. No sightings of 

the black bear occurred during field reconnaissance. Pearl River and Hancock Counties are both listed 

as having frequent reported occurrences (11 to 30 sightings) of black bears based on data from 2002 

to 2010 (Mississippi State University 2017). Based on reported occurrences of black bears in 

Mississippi, Pearl River and Hancock Counties have and there are no documents of it inhabiting the 

survey corridor. Because bears are larger, mobile animals, they are able to avoid temporary 

disturbances to their surroundings. Therefore, no direct impacts are anticipated. However, there will 

be a small amount of suitable habitat loss from the construction of the new railroad and increased 

fragmentation of habitat. Therefore, the project may adversely impact this state listed species.

Florida Panther - Federal and State listed – Endangered/Endangered

The Florida panther is tawny, brown on the back and pale gray underneath. It is one of 32 Puma 

concolor subspecies known by many names – puma, cougar, mountain lion, painter, catamount and 
Draft Wetlands and Threatened and Endangered Species Report • Threatened and Endangered Species

47 Project No. FRA-0023-00(003)/105494 101000-102000

panther. Panthers historically ranged across the southeastern United States including Arkansas, 

Louisiana, Mississippi, Alabama, Georgia, Florida, and parts of Tennessee and South Carolina. Now, 

the breeding population of Florida panthers is found only in the southern tip of Florida, south of the 

Caloosahatchee River. Females do not roam as widely and none has been documented outside of 

south Florida in decades.

Florida panthers are about 6 to 7 feet long – males are bigger than females. They are 

carnivores. They are skilled at hunting white-tailed deer, feral hogs, raccoons, and other mediumsized mammals and reptiles. Florida panthers also stalk birds.

Florida panthers utilize a diversity of warm climate habitats. They live in wetlands, swamps, upland 

forests, and stands of saw palmetto. Panthers are wide-ranging, secretive, and occur at low densities. 

They require large, contiguous areas to meet their social, reproductive, and energetic needs. Panther 

habitat selection is related to prey availability. Dense understory vegetation provides some of the 

most important feeding, resting, and denning habitat for panthers. The historic range of the Florida 

panther extended from Florida to Louisiana throughout the Gulf. Florida panthers live alone, unless 

a pair is mating or a female is raising cubs. Males roam much larger territories than the females. A 

male can occupy a territory over 200 to 250 square miles in size (National Wildlife Federation 2017).

The Florida panther probably once ranged over most of Mississippi. Unconfirmed reports of panthers 

in Mississippi over the past few years have been concentrated along the Mississippi River and along 

the lower Pearl River. No records could be located documenting the panther within the vicinity of the 

survey corridor. 

The corridor’s hardwood forested wetlands and swamp areas provide suitable habitat and food for 

the Florida panther, although it less frequently occurs in upland pine forests or pine savannahs. The 

lack of thick understory in most of the survey corridor is not suitable for denning. Therefore, a 

determination of may affect, not likely to adversely affect is recommended for this species. 

Finback Whale – Federal listed – Endangered

The fin or finback whale is a large baleen whale that belongs to the cetacean species, and measures 

up to 90 feet in length. This whale is considered the second biggest whale in existence in terms of 

length right after the blue whale. The diet of fin whales consists largely of crustaceans, krill, squid,

and fish. The fin whale can be found traveling throughout the world’s major oceans, with the 

exception of the coldest regions. 

No suitable habitat within the survey corridor. Therefore, a no effect determination is recommended 

for this species.

Humpback Whale - Federal listed – Endangered

An adult humpback whale can grow to an average length of 40 to 60 feet long and weigh as much as 

44 tons. These marine mammals are generally either a dark grey or black, with white patches on their 

stomach and knobs (known as tubercles) covering their head. 

The whale’s back is largely flat with a small dorsal fin located down the far side of its back; however,

when swimming the humpback may arch its back and flukes causing its back to look like a large hump.
Draft Wetlands and Threatened and Endangered Species Report • Threatened and Endangered Species

48 Project No. FRA-0023-00(003)/105494 101000-102000

Humpback whales have a pretty diverse diet when it comes to the baleen whale suborder and are 

known for eating small fish, krill, salmon, herring, mackerel, and capelin among other small prey. 

These whales hunt and feed during the summer months in cold waters and migrate toward warmer 

tropical areas during the winter months to mate and bear offspring.

No suitable habitat occurs within the project’s survey corridor. Therefore, a no effect determination 

is recommended for this species.

West Indian Manatee - Federal and State listed – Endangered/Endangered

Manatees are protected under the Marine Mammal Protection Act, which prohibits the take (i.e., 

harass, hunt, capture, or kill) of all marine mammals (USFWS 2016a). Manatees are found in marine, 

estuarine, and freshwater environments. The West Indian manatee, Trichechus manatus, includes 

two distinct subspecies, the Florida manatee (Trichechus manatus latirostris) and the Antillean 

manatee (Trichechus manatus manatus). Manatees have large, seal-shaped bodies with paired 

flippers and a round, paddle-shaped tail. They are typically grey in color (color can range from black 

to light brown) and occasionally spotted with barnacles or colored by patches of green or red algae. 

The muzzle is heavily whiskered and coarse, single hairs are sparsely distributed throughout the 

body. Adult manatees, on average, are about 9 feet long and weigh about 1,000 pounds. At birth, 

calves are between 3 and 4 feet long and weigh between 40 and 60 pounds.

No suitable habitat occurs within the project’s survey corridor. Therefore, a no effect determination 

is recommended for this species.

5.3 CONCLUSION

Due to potential suitable habitat observed within the survey corridor, the project may affect, but is 

not likely to adversely affect the following federally listed species: Louisiana quillwort, eastern indigo 

snake, red-cockaded woodpecker, wood stork, and the Florida panther.

The project would have no effect on all other federally listed species addressed in this document. No 

protected species were observed during field reconnaissance.

Only two state listed species may be negatively affected by the proposed project: the black bear and 

rainbow snake. Black bears are mobile animals and able to avoid temporary disturbances to their 

surroundings. Therefore, no direct impacts are anticipated. However, there will be a small amount 

of suitable habitat loss from the construction of the new railroad and increased fragmentation of 

habitat. The rainbow snake may be adversely impacted with the conversion of wetland and aquatic 

habitats to uplands as part of the proposed construction of the rail project. This construction may 

reduce the vegetative cover (habitat) and food source of the rainbow snake within the right of way 

and cause displacement. Potential impacts include being struck by construction equipment and 

vehicles when trying to escape its burrow/habitat, stress, and exposure to predators from lack of 

suitable cover. No other state lists species will be negatively affected by the proposed project.

Preface

Soil surveys contain information that affects land use planning in survey areas. They

highlight soil limitations that affect various land uses and provide information about

the properties of the soils in the survey areas. Soil surveys are designed for many

different users, including farmers, ranchers, foresters, agronomists, urban planners,

community officials, engineers, developers, builders, and home buyers. Also,

conservationists, teachers, students, and specialists in recreation, waste disposal,

and pollution control can use the surveys to help them understand, protect, or enhance

the environment.

Various land use regulations of Federal, State, and local governments may impose

special restrictions on land use or land treatment. Soil surveys identify soil properties

that are used in making various land use or land treatment decisions. The information

is intended to help the land users identify and reduce the effects of soil limitations on

various land uses. The landowner or user is responsible for identifying and complying

with existing laws and regulations.

Although soil survey information can be used for general farm, local, and wider area

planning, onsite investigation is needed to supplement this information in some cases.

Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/portal/

nrcs/main/soils/health/) and certain conservation and engineering applications. For

more detailed information, contact your local USDA Service Center (http://

offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil

Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/?

cid=nrcs142p2_053951).

Great differences in soil properties can occur within short distances. Some soils are

seasonally wet or subject to flooding. Some are too unstable to be used as a

foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic

tank absorption fields. A high water table makes a soil poorly suited to basements or

underground installations.

The National Cooperative Soil Survey is a joint effort of the United States Department

of Agriculture and other Federal agencies, State agencies including the Agricultural

Experiment Stations, and local agencies. The Natural Resources Conservation

Service (NRCS) has leadership for the Federal part of the National Cooperative Soil

Survey.

Information about soils is updated periodically. Updated information is available

through the NRCS Web Soil Survey, the site for official soil survey information.

How Soil Surveys Are Made

Soil surveys are made to provide information about the soils and miscellaneous areas

in a specific area. They include a description of the soils and miscellaneous areas and

their location on the landscape and tables that show soil properties and limitations

affecting various uses. Soil scientists observed the steepness, length, and shape of

the slopes; the general pattern of drainage; the kinds of crops and native plants; and

the kinds of bedrock. They observed and described many soil profiles. A soil profile is

the sequence of natural layers, or horizons, in a soil. The profile extends from the

surface down into the unconsolidated material in which the soil formed or from the

surface down to bedrock. The unconsolidated material is devoid of roots and other

living organisms and has not been changed by other biological activity.

Currently, soils are mapped according to the boundaries of major land resource areas

(MLRAs). MLRAs are geographically associated land resource units that share

common characteristics related to physiography, geology, climate, water resources,

soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically

consist of parts of one or more MLRA.

The soils and miscellaneous areas in a survey area occur in an orderly pattern that is

related to the geology, landforms, relief, climate, and natural vegetation of the area.

Each kind of soil and miscellaneous area is associated with a particular kind of

landform or with a segment of the landform. By observing the soils and miscellaneous

areas in the survey area and relating their position to specific segments of the

landform, a soil scientist develops a concept, or model, of how they were formed. Thus,

during mapping, this model enables the soil scientist to predict with a considerable

degree of accuracy the kind of soil or miscellaneous area at a specific location on the

landscape.

Commonly, individual soils on the landscape merge into one another as their

characteristics gradually change. To construct an accurate soil map, however, soil

scientists must determine the boundaries between the soils. They can observe only

a limited number of soil profiles. Nevertheless, these observations, supplemented by

an understanding of the soil-vegetation-landscape relationship, are sufficient to verify

predictions of the kinds of soil in an area and to determine the boundaries.

Soil scientists recorded the characteristics of the soil profiles that they studied. They

noted soil color, texture, size and shape of soil aggregates, kind and amount of rock

fragments, distribution of plant roots, reaction, and other features that enable them to

identify soils. After describing the soils in the survey area and determining their

properties, the soil scientists assigned the soils to taxonomic classes (units).

Taxonomic classes are concepts. Each taxonomic class has a set of soil

characteristics with precisely defined limits. The classes are used as a basis for

comparison to classify soils systematically. Soil taxonomy, the system of taxonomic

classification used in the United States, is based mainly on the kind and character of

soil properties and the arrangement of horizons within the profile. After the soil

scientists classified and named the soils in the survey area, they compared the

5
individual soils with similar soils in the same taxonomic class in other areas so that

they could confirm data and assemble additional data based on experience and

research.

The objective of soil mapping is not to delineate pure map unit components; the

objective is to separate the landscape into landforms or landform segments that have

similar use and management requirements. Each map unit is defined by a unique

combination of soil components and/or miscellaneous areas in predictable

proportions. Some components may be highly contrasting to the other components of

the map unit. The presence of minor components in a map unit in no way diminishes

the usefulness or accuracy of the data. The delineation of such landforms and

landform segments on the map provides sufficient information for the development of

resource plans. If intensive use of small areas is planned, onsite investigation is

needed to define and locate the soils and miscellaneous areas.

Soil scientists make many field observations in the process of producing a soil map.

The frequency of observation is dependent upon several factors, including scale of

mapping, intensity of mapping, design of map units, complexity of the landscape, and

experience of the soil scientist. Observations are made to test and refine the soillandscape model and predictions and to verify the classification of the soils at specific

locations. Once the soil-landscape model is refined, a significantly smaller number of

measurements of individual soil properties are made and recorded. These

measurements may include field measurements, such as those for color, depth to

bedrock, and texture, and laboratory measurements, such as those for content of

sand, silt, clay, salt, and other components. Properties of each soil typically vary from

one point to another across the landscape.

Observations for map unit components are aggregated to develop ranges of

characteristics for the components. The aggregated values are presented. Direct

measurements do not exist for every property presented for every map unit

component. Values for some properties are estimated from combinations of other

properties.

While a soil survey is in progress, samples of some of the soils in the area generally

are collected for laboratory analyses and for engineering tests. Soil scientists interpret

the data from these analyses and tests as well as the field-observed characteristics

and the soil properties to determine the expected behavior of the soils under different

uses. Interpretations for all of the soils are field tested through observation of the soils

in different uses and under different levels of management. Some interpretations are

modified to fit local conditions, and some new interpretations are developed to meet

local needs. Data are assembled from other sources, such as research information,

production records, and field experience of specialists. For example, data on crop

yields under defined levels of management are assembled from farm records and from

field or plot experiments on the same kinds of soil.

Predictions about soil behavior are based not only on soil properties but also on such

variables as climate and biological activity. Soil conditions are predictable over long

periods of time, but they are not predictable from year to year. For example, soil

scientists can predict with a fairly high degree of accuracy that a given soil will have

a high water table within certain depths in most years, but they cannot predict that a

high water table will always be at a specific level in the soil on a specific date.

After soil scientists located and identified the significant natural bodies of soil in the

survey area, they drew the boundaries of these bodies on aerial photographs and

identified each as a specific map unit. Aerial photographs show trees, buildings, fields,

roads, and rivers, all of which help in locating boundaries accurately.

Map Unit Descriptions

The map units delineated on the detailed soil maps in a soil survey represent the soils

or miscellaneous areas in the survey area. The map unit descriptions, along with the

maps, can be used to determine the composition and properties of a unit.

A map unit delineation on a soil map represents an area dominated by one or more

major kinds of soil or miscellaneous areas. A map unit is identified and named

according to the taxonomic classification of the dominant soils. Within a taxonomic

class there are precisely defined limits for the properties of the soils. On the landscape,

however, the soils are natural phenomena, and they have the characteristic variability

of all natural phenomena. Thus, the range of some observed properties may extend

beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic

class rarely, if ever, can be mapped without including areas of other taxonomic

classes. Consequently, every map unit is made up of the soils or miscellaneous areas

for which it is named and some minor components that belong to taxonomic classes

other than those of the major soils.

Most minor soils have properties similar to those of the dominant soil or soils in the

map unit, and thus they do not affect use and management. These are called

noncontrasting, or similar, components. They may or may not be mentioned in a

particular map unit description. Other minor components, however, have properties

and behavioral characteristics divergent enough to affect use or to require different

management. These are called contrasting, or dissimilar, components. They generally

are in small areas and could not be mapped separately because of the scale used.

Some small areas of strongly contrasting soils or miscellaneous areas are identified

by a special symbol on the maps. If included in the database for a given area, the

contrasting minor components are identified in the map unit descriptions along with

some characteristics of each. A few areas of minor components may not have been

observed, and consequently they are not mentioned in the descriptions, especially

where the pattern was so complex that it was impractical to make enough observations

to identify all the soils and miscellaneous areas on the landscape.

The presence of minor components in a map unit in no way diminishes the usefulness

or accuracy of the data. The objective of mapping is not to delineate pure taxonomic

classes but rather to separate the landscape into landforms or landform segments that

have similar use and management requirements. The delineation of such segments

on the map provides sufficient information for the development of resource plans. If

Custom Soil Resource Report

11
intensive use of small areas is planned, however, onsite investigation is needed to

define and locate the soils and miscellaneous areas.

An identifying symbol precedes the map unit name in the map unit descriptions. Each

description includes general facts about the unit and gives important soil properties

and qualities.

Soils that have profiles that are almost alike make up a soil series. Except for

differences in texture of the surface layer, all the soils of a series have major horizons

that are similar in composition, thickness, and arrangement.

Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity,

degree of erosion, and other characteristics that affect their use. On the basis of such

differences, a soil series is divided into soil phases. Most of the areas shown on the

detailed soil maps are phases of soil series. The name of a soil phase commonly

indicates a feature that affects use or management. For example, Alpha silt loam, 0

to 2 percent slopes, is a phase of the Alpha series.

Some map units are made up of two or more major soils or miscellaneous areas.

These map units are complexes, associations, or undifferentiated groups.

A complex consists of two or more soils or miscellaneous areas in such an intricate

pattern or in such small areas that they cannot be shown separately on the maps. The

pattern and proportion of the soils or miscellaneous areas are somewhat similar in all

areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.

An association is made up of two or more geographically associated soils or

miscellaneous areas that are shown as one unit on the maps. Because of present or

anticipated uses of the map units in the survey area, it was not considered practical

or necessary to map the soils or miscellaneous areas separately. The pattern and

relative proportion of the soils or miscellaneous areas are somewhat similar. AlphaBeta association, 0 to 2 percent slopes, is an example.

An undifferentiated group is made up of two or more soils or miscellaneous areas that

could be mapped individually but are mapped as one unit because similar

interpretations can be made for use and management. The pattern and proportion of

the soils or miscellaneous areas in a mapped area are not uniform. An area can be

made up of only one of the major soils or miscellaneous areas, or it can be made up

of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.

Some surveys include miscellaneous areas. Such areas have little or no soil material

and support little or no vegetation. Rock outcrop is an example.

Consultation Code: 04EM1000-2016-SLI-0677 July 20, 2016

Event Code: 04EM1000-2016-E-01445

Project Name: Port Bienville Railroad Project

Subject: List of threatened and endangered species that may occur in your proposed project

location, and/or may be affected by your proposed project

To Whom It May Concern:

The enclosed species list identifies threatened, endangered, proposed and candidate species, as

well as proposed and final designated critical habitat, that may occur within the boundary of

your proposed project and/or may be affected by your proposed project. The species list fulfills

the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the

Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 ). et seq.

New information based on updated surveys, changes in the abundance and distribution of

species, changed habitat conditions, or other factors could change this list. Please feel free to

contact us if you need more current information or assistance regarding the potential impacts to

federally proposed, listed, and candidate species and federally designated and proposed critical

habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of

the Act, the accuracy of this species list should be verified after 90 days. This verification can

be completed formally or informally as desired. The Service recommends that verification be

completed by visiting the ECOS-IPaC website at regular intervals during project planning and

implementation for updates to species lists and information. An updated list may be requested

through the ECOS-IPaC system by completing the same process used to receive the enclosed

list.

The purpose of the Act is to provide a means whereby threatened and endangered species and

the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2)

of the Act and its implementing regulations (50 CFR 402 ), Federal agencies are required et seq.

to utilize their authorities to carry out programs for the conservation of threatened and

endangered species and to determine whether projects may affect threatened and endangered

species and/or designated critical habitat.
A Biological Assessment is required for construction projects (or other undertakings having

similar physical impacts) that are major Federal actions significantly affecting the quality of the

human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2)

(c)). For projects other than major construction activities, the Service suggests that a biological

evaluation similar to a Biological Assessment be prepared to determine whether the project may

affect listed or proposed species and/or designated or proposed critical habitat. Recommended

contents of a Biological Assessment are described at 50 CFR 402.12.

If a Federal agency determines, based on the Biological Assessment or biological evaluation,

that listed species and/or designated critical habitat may be affected by the proposed project, the

agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service

recommends that candidate species, proposed species and proposed critical habitat be addressed

within the consultation. More information on the regulations and procedures for section 7

consultation, including the role of permit or license applicants, can be found in the "Endangered

Species Consultation Handbook" at:

http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF

Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle

Protection Act (16 U.S.C. 668 ), and projects affecting these species may require et seq.

development of an eagle conservation plan

(http://www.fws.gov/windenergy/eagle_guidance.html). Additionally, wind energy projects

should follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing

impacts to migratory birds and bats.

Guidance for minimizing impacts to migratory birds for projects including communications

towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at:

http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm;

http://www.towerkill.com; and

http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/comtow.html.

We appreciate your concern for threatened and endangered species. The Service encourages

Federal agencies to include conservation of threatened and endangered species into their project

planning to further the purposes of the Act. Please include the Consultation Tracking Number in

the header of this letter with any request for consultation or correspondence about your project

that you submit to our office.

Endangered Species Act Species List

There are a total of 19 threatened, endangered, or candidate species on your species list. Species on this list should be

considered in an effects analysis for your project and could include species that exist in another geographic area. For

example, certain fish may appear on the species list because a project could affect downstream species. Critical habitats

listed under the Has Critical Habitat column may or may not lie within your project area. See the Critical habitats

within your project area section further below for critical habitat that lies within your project. Please contact the

Hi Amber,

  

It was nice speaking with you earlier. I apologize for the difficulty in using our online database. I have attached a word

file with these species. Please forgive the formatting and note at the top there is a key for colored fonts. Red = federally

endangered, and green = federally threatened. There is a separate column for state endangered.  

  

I hope this helps!
