DesertXpress Project Special‐Status Plant

Survey Report for the Proposed Segment 4C Alignment,

San Bernardino County

Introduction

This report provides the methods and results of the special‐status plants survey within the 

environmental study limits (ESL) of the proposed Segment 4C alignment. The ESL includes the 

footprint for the rail alignment in addition to a 100‐foot wide buffer on either side of the alignment. 

In preparing this report, ICF International compiled and reviewed information from previously 

completed botanical survey reports prior to initiating pedestrian surveys for the proposed 

alignment. 

Project Description

DesertXpress Enterprises, LLC (Applicant) proposes to construct and operate a privately financed 

interstate high‐speed passenger train between Victorville, California and Las Vegas, Nevada. The 

proposed action is to construct and operate a fully grade‐separated, dedicated, double‐track 

passenger‐only railroad along an approximately 200‐mile corridor from Victorville, California, to 

Las Vegas, Nevada (Figure 1). The Federal Railroad Administration (FRA) is the federal lead agency 

for the proposed action. 

Project Location

Located in San Bernardino County, California, and Clark County, Nevada, the proposed Segment 4C 

alignment would be approximately 20.7 miles long (Figure 1). The west end of the Segment 4C 

alignment starts in Mountain Pass within the I‐15 right‐of‐way. The rail alignment then leaves the I‐

15 freeway right‐of‐way and heads northeast, passing through three new dual track tunnels into the 

Clark Mountain Range. The Segment 4C alignment travels northward from the Clark Mountains and 

turns east to cross the California‐Nevada state line and connects back to the I‐15 freeway corridor in 

the vicinity of Primm, Nevada. Within the vicinity of Primm, the alignment would connect with the 

proposed Segment 5B rail alignment.  

Project Setting

The segment 4C rail alignment is located within the State Line Pass, Ivanpah Lake, Clark Mountain, 

Mineral Hill, and Mescal Range (USGS) 7.5‐ minute quadrangles, and is located within the Mojave 

Desert bioregion of the California Floristic Province (Hickman 1993).  Elevations of the proposed 

alignment range from approximately 2600 to 4850 feet above mean sea level (792‐1478 meters). 

Precipitation in the area averages approximately 8.66 inches per year and falls as rain and snow 

(NRCS 2010). Habitats in the project site and in the project vicinity are typical of mountain slopes 

and valleys in the Mojave Desert and are dominated by creosote and Mojave mixed woody scrub.

Definitions

Special‐status plants are species that are legally protected under the federal Endangered Species Act 

(ESA), California Endangered Species Act (CESA), Nevada Administrative Code (NAC), or other 

federal and state regulations, as well as species considered sufficiently rare by the scientific 

community to qualify for such listing.  

For the purposes of this botanical report, special‐status plants are: 

 species listed or proposed for listing as threatened or endangered under ESA (50 Code of 

Federal Regulations [CFR] 17.12 [listed plants] and various notices in the Federal Register [FR] 

[proposed species]); 

 species that are candidates for possible future listing as threatened or endangered under ESA 

(72 FR 69034, December 6, 2007; 74 FR  57804–57878, November 9. 2009); 

 species listed or proposed for listing by the State of California as threatened or endangered 

under CESA (14 CCR 670.5); 

 species that meet the definitions of rare or endangered under the California Environmental 

Quality Act (CEQA) (State CEQA Guidelines Section 15380); 

 plants listed as rare under the California Native Plant Protection Act (California Fish and Game 

Code Section 1900 et seq.); 

 plants considered by California Native Plant Society (CNPS) to be “rare, threatened, or 

endangered in California” (Lists 1B and 2, California Native Plant Society 2010) (State CEQA 

Guidelines Section 15381[d]);  

 plants on CNPS’s Lists 3 and 4 (plants about which more information is needed to determine 

their status and plants of limited distribution) (California Native Plant Society 2010) may be 

included as special‐status species on the basis of local significance or recent biological 

information. 

 plant species listed as “sensitive” by the BLM (BLM 2010) 

 plant species listed as “covered” by the Clark County Habitat Conservation Plan (USFWS 2000) 

Methods

Pre‐Field Investigation: Special‐Status Plants

Before conducting the field surveys, ICF botanists reviewed existing database information to 

determine the location and types of botanical resources that could exist in the survey area. This pre‐

field investigation included searches of the California Natural Diversity Database (CNDDB) 

(California Natural Diversity Database 2010), and the CNPS’s online Inventory of Rare and

Endangered Plants (California Native Plant Society 2010). These databases provide information on 

known occurrences of state‐ and federally listed plants and CNPS Lists 1B, 2, and 3 plants. Both 

databases can be queried by USGS 7.5‐minute quadrangle as described below to generate a list of 

sensitive plant species with known occurrences in the project region (region is conventionally 

defined as the quadrangle (s) within which the project site is located and the immediately 

surrounding quadrangles). CNPS List 4 plants are recorded at the county level and are not included

on lists generated from specific quadrangles. The project botanists reviewed the list of CNPS List 4 

plants recorded in San Bernardino County and were prepared to evaluate these species on the basis 

of local significance or recent biological information if they were encountered in the field.  

The database searches were conducted for the State Line Pass, Ivanpah Lake, Clark Mountain, 

Mineral Hill, and Mescal Range quadrangles in addition to any quadrangle adjacent to the 

aforementioned. The results of the CNDDB and CNPS records search are provided in Appendix A.  

Additional resources consulted included information from previously completed project reports and 

other botanical evaluations in the region.. The resulting information was used to prepare a list of 

special‐status plants that could occur at the project site (Table 2). The records search found that 84 

special‐status plants had been previously observed in the vicinity of the project site. The 

environmental study area was determined to be suitable habitat for 40 of these species. No special‐

status plant species have been recorded within the project ESL. Details of these plants—their status, 

distribution, habitat, and an assessment of their potential to occur in the study area—are in Table 2. 

The existing information on species distributions and habitat requirements was reviewed to 

determine the potential for each species to occur at the project site.  

Pre‐Field Investigation: Rare Natural Communities

The Natural Communities Program of the CNDDB maintains records on occurrences of natural 

communities considered to be rare or sensitive by California Department of Fish and Game (DFG). A 

records search was conducted as described above, and found that two occurrences of one rare 

natural community, have been recorded in the region of the project site (Appendix A).  Based on the 

rare communities recorded from the project region and the location of the project site it was 

determined that the mesquite shrubland rare natural community has the potential to occur in the 

project site.  

Field Surveys: Special‐Status Plants

ICF botanists conducted  the special‐status plant surveys on March 29  through April 1, 2010  (John 

Holson,  Seth  Kirby),  April  19  through  April  23  (John  Holson,  Ramona  Robison,  Bruce  Lund,  Glen 

Kinoshita), and May 24 through May 27, 2010 (John Holson, Seth Kirby, Bruce Lund, Rob Preston).  

The surveys were  timed  to coincide with  the blooming and identification periods of special‐status 

plant species in  the area.  Weather conditions during  the visits were varied, with weather ranging 

from  clear  and  sunny  to  overcast  with  light  snow.  Details  of  the  weather  conditions  during  each 

survey are discussed below.

Segment 4C Alignment 4 November 2010

ICF 06334.06

All botanical surveys were conducted in accordance with DFG’s Protocols for Surveying and

Evaluating Impacts to Special Status Native Plant Populations and Natural Communities (California 

Department of Fish and Game 2009). The botanists that conducted the surveys meet the required 

qualifications to conduct botanical surveys and are familiar with the vegetation and flora of the 

region. The surveys were conducted when the potentially occurring special‐status plants species 

were evident and identifiable, according to their known blooming and identification periods (see 

Table 3).  

The botanists covered the entire study area, employing a transect approach to the ESL. They 

examined the study area on foot, focusing on habitats and microhabitats that had potential to 

support sensitive species in the region. Areas that were inaccessible by foot (e.g., steep slopes) were 

examined to the extent possible using binoculars and the naked eye. The survey intensity was 

considered to be high because approximately 95% of the study area was accessible and was 

surveyed. Special‐status plant species found within the ESL were marked and mapped using a sub‐

meter Tremble GPS unit; maps containing the aforementioned data can be found in Appendix B. The 

botanists accumulated a running checklist of observed plants for the project site during the surveys 

(Appendix C).  

The survey was floristic, with every higher plant encountered identified to the lowest taxonomic 

level (species, subspecies, or variety) possible, based on the availability of flowers, fruits, or other 

diagnostic features. A few plants could not be identified below the level of genus because they lacked 

flowers or other characteristics needed to differentiate between similar species. However, all plants 

were identified to the lowest taxonomic level necessary to determine whether they were special‐

status plants or were species with unusual or significant range extensions. Resources used to 

identify plants included The Jepson Manual (Hickman 1993), A California Flora (Munz and Keck 

1959), and internet resources such as Calflora (2010). Nomenclature follows The Jepson Manual

(Hickman 1993) and updates published online by the Jepson Flora Project, Jepson Online 

Interchange (University of California 2010).  

Field Surveys: Natural Communities

Vegetation surveys were conducted concurrently with special‐status plant surveys in order to assess 

and map the vegetation types in the project alignment, including ancillary facilities.  The natural 

communities at the project site were identified and mapped in the study area following the Central 

Mojave Vegetation Database (USGS 2004) classification.  

Results

The cumulative list of plant species observed at the project site is in Appendix C. In total, 203 plant 

taxa were observed in the ESL, of which approximately 3% were nonnative. Details on communities 

and plant species observed are included below. Representative photos of some of the onsite 

vegetation communities can be found in Appendix D. 

Vegetation Communities

The project site supports six vegetation communities, all of which are natural communities found in 

the local area. The vegetation communities are described in Table 2.

Special‐Status and Rare Plants

In summary, seven special‐status plant species (CNPS Lists 1 and 2) and one CNPS List 4 plant 

species were found within the project site. The status, geographic range, and habitats of these 

species can be found in Table 3. A map containing the locations of these plants in reference to the 

Segment 4C alignment can be found in Appendix B. 

CNPS List 1 Plants

One CNPS list 1B.2, Rusby’s desert mallow (Sphaeralcea rusbyi var. eremicola), has been documented 

at the project sites during the botanical surveys in 2010 and is summarized in Table 3. Rusby’s 

desert mallow is also listed by the BLM as “sensitive.”

CNPS List 2 Plants

Two 2.1 special‐status plant species [Mojave milkweed (Asclepias nyctaginifolia), desert pincushion 

(Coryphantha chlorantha)], three 2.2 special‐status plant species [small‐flowered androstephium 

(Androstephium breviflorum), Tidestrom’s milkvetch (Astragalus tidestromii), Parish’s club‐cholla

(Grusonia parishii)], and one 2.3 special‐status plant species [Mormon needle grass (Achnatherum

aridum)] have been documented at the project sites during the botanical surveys in 2010 and are 

summarized in Table 3.  

CNPS List 4 Plants

One CNPS List 4.3 species, Utah vine milkweed (Funastrum utahense), has been documented and is 

also included in Table 3.  

Although CNPS List 4 plants do not meet the definition of “rare, threatened, or endangered,” they are 

considered of limited distribution in California. Specific List 4 species in a project area may be 

considered of local concern or rare or unique to a region and therefore qualify as special‐status 

species under CEQA (State CEQA guidelines Sections 15380 and 15125[a]) if for example they are at 

the periphery of the species’ range, at the type locality, or occur in unusual habitats or elevations.  

Rare Natural Communities

As shown in Appendix B, several areas on site are characterized as mesquite shrubland.  This 

community is considered “Rare” by the CDFG and of “high priority for inventory” (CNDDB 2003). 

Mesquite shrubland (3.08 acres) occurs on site, near the southernmost end of Segment 4C 

(Appendix B). This community, which is found along the edge of a major wash system, is dominated 

by mesquite shrubs (Prosopis glandulosa), and contains other shrub species such as four‐wing 

saltbush (Atriplex canescens) and cheesebush.
