 Chapter 1 — Purpose and Need

The Rainwater Basin was once covered by native prairie and was largely isolated from streams and natural 

drainages. Heavy rains or snow melts would fill the 

numerous shallow depressions scattered throughout 

the region. Its geographic location in the mid portion 

of the central flyway made the Rainwater Basin an 

oasis of food and rest for millions of birds making their 

northward migration to their breeding grounds. Waterfowl, shorebirds, and grassland birds would dominate the skies, with raptors following the migration. 

Today, the landscape is dramatically changed. The 

expansive grasslands and numerous wetlands have 

been replaced with fields of corn and soybeans. Roads 

traverse the landscape at 1-mile intervals, and small 

rural communities are scattered within a 10-mile radius of one another. Many of the wetlands have been 

filled or drained, reducing their numbers to only about 

16 percent of their historic level. 

The remaining wetlands play an increasingly important role in providing resting and feeding areas for 

the millions of birds that continue to use the central 

flyway each spring and fall. However, their function 

as wetlands has been diminished by sedimentation, 

nutrient runoff, and reduced water runoff within the 

watersheds. Waterfowl and shorebirds are forced to 

crowd into fewer areas and compete for the limited 

amount of natural food provided by the wetlands.

The proposed Rainwater Basin Expansion Project 

(Rainwater Basin Wetland Management District Expansion Project) would contribute to the conservation 

efforts described in such plans as the North American Waterfowl Management Plan, the United States 

Shorebird Conservation Plan, Partners in Flight, the 

North American Waterbird Conservation Plan, and 

the Nebraska Natural Legacy Plan. 

Proposed Action

The Service (U.S. Fish and Wildlife Service) is proposing the Rainwater Basin Expansion Project to expand 

the number of acres in Nebraska’s Rainwater Basin 

that it can own in fee title or hold in easements. Currently, the Service has been authorized to purchase 

24,000 acres of wetland habitat within the Rainwater 

Basin region. To date, 22,023 acres have been acquired. 

An additional 4,505 acres have been gifted, primarily 

from other Federal agencies. 

The Service proposes to strategically acquire an 

additional 9,177 acres in fee title and 5,000 acres in conservation easements (table 1). All purchases would be 

from voluntary sellers. These 14,177 acres represent 

0.36 percent of the Rainwater Basin. 

Fee-title acquisition would focus on lands that meet 

one of two criteria: wetland portions that adjoin properties already partially held in fee title by the Service 

and larger semipermanent wetlands located within a 

wetland complex of smaller seasonal wetlands. These 

properties would be managed as WPAs (Waterfowl 

Production Areas). Management practices would include prescribed burning, livestock grazing, limited 

haying, and periodic resting (USFWS 2007). The areas 

would be open to public recreation, including hunting, 

wildlife viewing, photography, and environmental interpretation and education. 

Conservation easements would be purchased on 

privately owned property containing smaller wetlands. 

The easements would protect the wetlands from being drained or filled. Surrounding upland buffer areas 

under easement would be planted with native grasses 

and protected from commercial and residential development, although haying and grazing would be allowed.

Project Area

The Rainwater Basin is located near the center of the 

Great Plains. It encompasses approximately 6,100 

square miles, covering portions or all of 21 counties in 

south-central Nebraska (figure 1) (LaGrange 2005). At 

its widest, it is 160 miles across, extending from Gosper 

County to central Seward County. The northern edge 

parallels the central Platte River, and the southern 

edge lies about 10 miles north of the Kansas border.

The topography ranges from flat to gently rolling 

loess plains that historically supported a tallgrass and 

mixed-grass prairie ecosystem. The area is geologically new and has not developed a complete system of 

streams to drain surface water. The shallow depressions, formed predominately by wind scouring, are 

quickly filled with runoff following spring snow melts 

and heavy rains—thus the name Rainwater Basin. 

The size of the depressions or wetlands ranges from 

a few acres to more than 1,000 acres. 

The climate is semiarid, with annual precipitation 

ranging from 21 to 28 inches (west to east). Annual 

evaporation for small bodies of water averages 46 

inches; about 77 percent of that amount is lost from 

May through October. Most of the precipitation occurs in the spring and summer. Heavy rains fill the 

wetlands, but they dry out in a matter of a few weeks. 

Wind scouring of dry wetland basins has caused the 

finer silts and loam soils to be removed, while the 

heavier clays remain in the wetland bottoms. In some 

wetlands, the impervious clay layer that has formed 

extends as deep as 72 inches.

The region lies in the center of the central flyway. 

Migratory birds from the gulf coast states, Mexico, 

and areas further south funnel through the Rainwater 

Basin before spreading outward toward the Prairie 

Pothole Region and areas further north. The flight 

pattern of the migration resembles the shape of an 

hourglass, with the Rainwater Basin and the central 

Platte River being at the narrowest part (figure 2). 

Prominent wetland areas to the south include the 

Playa Lakes of Texas, New Mexico, Oklahoma, and 

Kansas. To the north is the Prairie Pothole Region. 

The prominence of the constriction emphasizes the 

importance of the Rainwater Basin as a resting and 

feeding stopover for millions of migratory birds.

The nearby Platte River complements the value 

of the Rainwater Basin. In years when drought or 

spring snowstorms make the wetlands unavailable, 

many of the birds move to the river. 

The Rainwater Basin lies over the Ogallala aquifer, 

providing water for irrigated agriculture, primarily 

corn and soybeans. Waste grain provides food for migrating waterfowl and cranes. 

Purpose of and Need for 

Proposed Action

Recognizing the importance of the Rainwater Basin 

as stopover and breeding habitat for millions of migratory birds, the Service began protecting wetlands with 

fee-title acquisition in 1962. NGPC (Nebraska Game 

and Parks Commission) took the same approach. All 

properties were purchased from voluntary sellers. 

In most situations, it was the owners of the deeper, 

wetter portions of the individual wetland basins who 

were willing to sell. Many surrounding owners of the 

remaining portion of a wetland chose to retain ownership and farm their portion during drier years. This 

split ownership greatly reduced the effectiveness of 

the publicly owned portion of the wetland. This is because if a drained wetland has only a small portion in 

private ownership, the wetland cannot be effectively 

restored without purchasing the privately held portion. For example, a 200-acre drained wetland with 

180 acres in public ownership and 20 acres in private 

ownership remains effectively drained until the last 20 

acres are purchased. These generally small, privately 

owned tracts connected to publicly owned wetlands 

are referred to as “roundouts.”

Now, nearly 50 years after the Service began protecting wetlands with fee-title acquisition, only 8.5 

percent (18,067 acres) of the historic wetland acres 

are in public ownership. Public wetland areas (State 

and Federal) are represented by 90 distinct properties 

containing all or portions of 168 wetlands, or 1.5 percent of the 11,000 historic wetlands (USFWS, Grand 

Island GIS Shop, unpublished). 

The partners of the Rainwater Basin Joint Venture 

(see related actions and activities) examined wetland 

acres in private ownership that may hamper the ability 

to manage wetlands owned by the Service or NGPC. 

The partners also examined the nutritional and energetic needs of all waterfowl while staging in the region. 

The total additional acres needing protection in the 

Rainwater Basin are based on this collaborative work. 

FEE TITLE 

Taking into consideration the factors described above, 

the Rainwater Basin Joint Venture projected that an 

additional 7,790 wetland acres need to be purchased 

in fee title by all partners. The Service would strive 

to acquire 6,500 wetland acres. The required upland 

buffer around these wetlands is estimated to be 2,677 

acres. Ownership of properties purchased with the authorization of this proposal would be held by the Service as part of the National Wildlife Refuge System. 

The properties would be managed as WPAs.

Fee-title acquisition would focus on two types of 

wetland properties. The primary focus would be on 
Chapter 1 — Purpose and Need 3

Figure 1 . Rainwater Basin Wetland Management District .
4 Draft EA, Rainwater Basin Wetland Management District Expansion

portions of privately owned wetland roundouts that 

share a boundary with wetlands already owned by 

the Service. The secondary focus would be on large 

wetlands that can serve as a core wetland within a 

complex of smaller, privately owned wetlands. 

Currently, 38 WPAs need additional acquisition 

to complete ownership of the properties’ hydric or 

wetland soil. Adjoining roundout property, which 

represents a significant portion of the total wetland 

area, would need to be purchased in fee title to allow 

full management of the wetland. Adjoining wetland 

portions that represent a small portion of the wetland 

and do not significantly impact management on the 

Service’s portion could be protected with conservation easements. Most properties that could serve as 

core wetlands within a wetland complex are currently 

drained and would be more difficult to purchase. Both 

of these acquisition approaches would have a positive 

effect on bird use within the local area.

CONSERVATION EASEMENTS 

The Joint Venture determined that an additional 9,239 

acres of wetlands need to be protected by perpetual 

easements (Andy Bishop, coordinator, Rainwater Basin 

Joint Venture, Nebraska; personal communication; May 

12, 2010). The Service would strive to acquire 2,500 

wetland acres and 2,500 upland buffer acres through 

conservation easements. 

Easements purchased by the Service would be 

grassland-wetland easements that would require the 

upland to be in permanent grassland. The easement 

would restrict commercial and residential development, 

but would allow the landowner to use the property for 

haying, grazing, and recreation. Allowing access to the 

property will remain a landowner’s right.

The Rainwater Basin Wetland Management District has administered 31 conservation easements 

within the region since before 2009. Eight of these 

easements are within the Rainwater Basin, but only 

one has significant wetland habitat for migratory birds. 

Since 2009, the Service has acquired five additional 

grassland-wetland conservation easements within the 

Rainwater Basin. Those easements, acquired under 

the current land acquisition authority, follow the same 

guidelines proposed in this document.

The NRCS (Natural Resources Conservation Service) is expected to be the dominant partner with the 

Service in obtaining perpetual easements under its 

WRP (Wetlands Reserve Program). In 2010, the WRP 

launched a pilot project that allows landowners to sell 

a WRP easement, with the buyer retaining the right 

to graze the property with only minimal restrictions. 

The reason for allowing grazing is that it helps to keep 

wetlands in an early successional, seed-producing state, 

making it more valuable to migrating birds. 

WATERFOWL NUTRITIONAL NEEDS 

The Rainwater Basin is internationally recognized 

for its importance as a migration stopover. Birds in 

migration have additional nutrient demands, not only 

for the actual migration but to reach a body condition 

needed for egg production (Devries et al. 2008). 

Historically, the Rainwater Basin has provided 

migrating birds with natural foods from thousands 

of shallow wetlands. It is impossible to estimate how 

much food these wetlands provided for waterfowl 

hundreds of years ago, but recent research into the 

nutrient value of common native wetland plants documents their high value. 

The Rainwater Basin Joint Venture has used data 

on energetic needs and the number of bird-use days 

in the Rainwater Basin to estimate that migratory 

waterfowl need a total of 15.6 billion Kcal (kilocalories) during their stay in the region, consisting of both 

natural and agricultural sources (Rainwater Basin 

Joint Venture, unpublished report, 2010).

The conversion of wetlands and grassland to cropland has caused migrating waterfowl to feed heavily 

on waste grain (top chart in figure 3). Although waste 

grain meets the caloric requirements of waterfowl, 

it does not provide the amino acids and minerals required in their diet. 

One of the goals of the Rainwater Basin Joint 

Venture is to increase the amount of available energy 

for waterfowl from natural, nonagricultural foods to 

4.4 billion Kcal, or 28 percent of their diet (Rainwater Basin Joint Venture, unpublished report). A 2004 

GIS (geographic information system) assessment of 

available wetland habitat and food indicated that, 

given their current number and condition, the region’s 
Chapter 1 — Purpose and Need 5

Figure 3 . Sources of nutrients for migrating waterfowl .
6 Draft EA, Rainwater Basin Wetland Management District Expansion

wetlands are capable of only providing 13.6 percent of 

the birds’ dietary needs (USFWS, Grand Island GIS 

Shop, unpublished). 

In addition to loss of wetlands, remaining wetlands with altered hydrology or no management for 

wildlife are more prone to developing dense stands 

of late-successional plants such as reed canary grass, 

cattail, and bulrush. Research suggests that wetlands 

dominated by late-successional plants can provide 

only about one-tenth of the kilocalories (0.025 million 

Kcal/acre) of wetlands in an early-successional stage 

(USDA, NRCS 2008).

The proposed action would contribute to meeting 

the nutritional needs of migratory birds determined by 

the Rainwater Basin Joint Venture. Better vegetation 

management at existing wetlands and an increase in 

the number of wetlands providing natural foods are 

required. The bottom chart in figure 3 shows where 

future wetland foods will come from. Acquisition and 

management of additional wetlands would increase the 

projected contribution from public wetlands from 5.8 

to 21.3 percent. This action would provide the greatest amount of increased nutrition with the fewest 

number of acres. 

Easement purchases and associated management 

would need to be increased to provide 10.2 percent of 

needed calories. Short-term wetlands are those that 

have less than 99-year easements or land use contracts. These wetlands would be expected to provide 

almost 5 percent of needed calories. Privately owned 

wetlands that have no protection would be expected 

to continue to provide 6 percent of the wetland foods. 

Decisions to Be Made

The Service’s planning team (see appendix B) will 

complete an analysis of the alternatives. Based on 

the analysis documented in this environmental assessment, the Service’s Regional Director of Region 

6, with the concurrence of the Director of the U.S. 

Fish and Wildlife Service, may make two decisions:

■ Determine whether the Service should expand 

the acquisition authority for the Rainwater Basin 

Wetland Management District; and,

■ If yes, determine whether the selected alternative 

would have a significant impact on the quality of 

the human environment. The National Environmental Policy Act of 1969 requires this decision. 

If the quality of the human environment would not 

be significantly affected, a finding of no significant 

impact will be signed and made available to the 

public. If the alternative would have a significant 

impact or impacts, completion of an environmental impact statement would be required in order 

to address those impacts.

Issues Identified and 

Selected for Analysis

Two public scoping meetings were held in Clay Center and Holdrege, Nebraska, in January 2011. Public 

comments were taken at these scoping meetings to 

identify issues to be analyzed for the proposed action. 

Approximately 33 landowners, citizens, and elected 

representatives attended the meetings. Additionally, 

16 letters providing comments and identifying issues 

and concerns were received.

The Service’s field staff contacted local government officials, other public agencies, and conservation groups that have expressed an interest in and a 

desire to provide a sustainable future for wetlands in 

the Rainwater Basin region. Approximately 170 fact 

sheets were mailed out, and project information was 

also made available at the Rainwater Basin Wetland 

Management District and regional planning Web sites.

Many of the comments related to the biological 

needs of waterfowl and socioeconomic issues. Comment topics are summarized below. 

BIOLOGICAL ISSUES

■ Concern about past and future loss of wetlands 

within the Rainwater Basin.

■ Concern about providing adequate habitat for 

spring migration.

■ Concern about the value of the region for migrating birds and the need to protect declining species.

■ Concern that farm programs and increased interest in biofuels may cause loss of the remaining unprotected wetlands.

■ Concern that the energetics model used to determine the number of acquisition acres is not a valid 

or accurate model.

■ Concern that wetlands in public ownership are 

not being managed for the benefit of all wildlife, 

including pheasants.

SOCIOECONOMIC ISSUES

■ Concern that land protection discourages or negatively affects economic activity in the area.

■ Concern about the loss of taxes paid to the county, 

placing a greater tax burden on local taxpayers.

■ Concern about acquisition driving up land prices.

■ Concern that conversion of farmland to public 

ownership will decrease the human population 

and support for schools, roads, and other services.

■ Concern that local government should be given more 

authority to approve or disapprove land acquisitions and to determine the use of public property. 
Chapter 1 — Purpose and Need 7

■ Concern that funding should be made available to 

compensate landowners for their privately owned 

wetlands.

■ Concern that the Service should work with landowners to enhance wetlands on private property.

ISSUES NOT SELECTED FOR DETAILED ANALYSIS

At one of the scoping meetings, the accuracy of the 

energetics models was called into question. No detailed analysis of this issue was performed for this environmental assessment. This model clearly assumes 

that the data used to estimate the energetic needs of 

waterfowl within Rainwater Basin came from a large 

amount of research not specific to this area. For example, the energetic value (Kcal) of a particular wetland plant studied in another part of the country is 

assumed to have an energetic value similar to that of 

the same plant species within the Rainwater Basin. 

The validity of this assumption is currently unknown 

and would require site-specific research. The energetic 

value given to plants in the Rainwater Basin, however, 

represents the best information available. Information from the energetic model has helped the Service 

better understand the importance of the Rainwater 

Basin for migratory waterfowl, not just as a resting 

area but also as a source of amino acids and minerals. 

The issue of land management on WPAs is addressed 

only in general terms in this document. Land management actions depend on a large number of variables, 

including existing vegetative conditions, site-specific 

objectives, past management actions, seasonal weather 

conditions, and other planned management actions. In 

addition, the Wetland Management District in 2007 developed a Comprehensive Conservation Plan (USFWS 

2007) for Service lands within the Rainwater Basin 

that outlined and analyzed land management actions.

A common concern expressed by the public pertains to wetland grazing and pheasant habitat. The 

Rainwater Basin Wetland Management District commonly receives comments that the Service does not 

do as much as it could to increase pheasant populations. Although pheasants are recognized as part of 

the diversity provided by WPAs, the pheasant is a 

State-managed species and not a Service responsibility. The purpose of the Wetland Management District, 

as described in the Migratory Bird Hunting and Conservation Stamp Act, is to manage migratory birds. 

National Wildlife Refuge 

System and Authorities

The mission of the National Wildlife Refuge System 

is to administer a national network of lands and waters for the conservation, management, and, where 

appropriate, restoration of fish, wildlife, and plant 

resources and their habitats within the United States 

for the benefit of present and future generations of 

Americans.

Lands acquired under the proposed action would 

be administered as part of the Refuge System in accordance with the National Wildlife Refuge System 

Administration Act of 1966 and other relevant legislation, executive orders, regulations, and policies.

Conservation of additional wildlife habitat in the 

Rainwater Basin region would also continue to be 

consistent with the following laws, policies, and management plans:

■ Migratory Bird Treaty Act (1918)

■ Migratory Bird Hunting and Conservation Stamp 

Act (1934)

■ U.S. Fish and Wildlife Act (1956)

■ Land and Water Conservation Fund Act (1965)

■ Endangered Species Act (1973)

■ North American Waterfowl Management Plan (1994)

■ National Wildlife Refuge System Biological Integrity, Diversity, and Environmental Health (2001)

■ Migratory Non-Game Birds of Management Concern in the U.S. (2002)

Related Actions and 

Activities

The Service is working with other public and private 

entities to maintain wildlife habitat within the Rainwater Basin region. Many organizations in Nebraska 

have recognized the ecological significance of the 

region and the need to promote conservation in concert with production agriculture. Wetland acquisition 

and restoration has been done by the NGPC, NRCS, 

Ducks Unlimited, and The Nature Conservancy. Local 

Natural Resource Districts have worked closely with 

conservation partners to maintain a balance between 

wetland habitats and agriculture. 

In 2007, the Wetland Management District developed a CCP (Comprehensive Conservation Plan) 

(USFWS 2007) for Service lands within the Rainwater Basin. The document identifies land management 

activities planned by the Service through 2022. The 

need for additional land acquisition was identified as 

important in the draft CCP sent out for public comment and the subsequent final document. 

RAINWATER BASIN JOINT VENTURE 

The Rainwater Basin was identified as a habitat of 

major concern by the North American Waterfowl 

Management Plan, establishing it as a focus area for 

a joint venture (Canadian Wildlife Service and U.S. 
8 Draft EA, Rainwater Basin Wetland Management District Expansion

Fish and Wildlife Service 1986). Partners involved in 

the formation of the joint venture included the Service, 

the NGPC, Ducks Unlimited, the NRCS, Little Blue 

Natural Resource District, and the National Audubon 

Society. Its current partners include many of the same 

organizations plus other Natural Resource Districts, 

The Nature Conservancy, and private landowners. 

The Rainwater Basin Joint Venture is currently 

in the process of rewriting its Implementation Plan 

(Gersib et al. 1992). The newer version is expected to 

identify a need to acquire an additional 20,000 acres 

(about 60 percent of which would be perpetual easements). One proposed strategy is developing working 

landscapes, which involves the purchase and restoration of wetlands and grasslands, with the property 

being resold to the private sector once a conservation 

easement has been established. The easement would 

allow livestock grazing and dryland haying, but no 

farming. Public access would also remain with the 

landowner. This approach would protect wetlands, 

restore grasslands, and provide agricultural income 

to the landowners. 

DUCKS UNLIMITED 

Ducks Unlimited has long recognized the Rainwater 

Basin as a focus area for wetland conservation efforts. 

Its goal is to secure a base of wetland complexes to 

restore the region’s function for waterfowl. In 2002, 

it began acquiring the Verona Complex in the central 

portion of the Rainwater Basin. Much of the property, 

including both the wetland and the surrounding upland, 

has required restoration. Ducks Unlimited’s Rainwater 

Basin initiative uses multiple approaches, consisting 

of land acquisition, wetland restoration, wetland management, and affecting public policy. The land acquisition portion involves the purchase of land containing 

existing or restorable wetland habitat. Once Ducks 

Unlimited has restored the wetlands, the property 

may be sold to a public agency or to a private buyer 

with a conservation easement in place. The proceeds 

from the sale are then used to repeat the process. 

NEBRASKA GAME AND PARKS COMMISSION 

NGPC continues to work toward acquisition, restoration, and management of Rainwater Basin wetlands. 

Currently, it owns approximately 6,700 wetland 

acres. Its philosophy of acquisition, restoration, and 

management of its lands mirrors that of the Service. 

NGPC also faces the problems of split ownership and 

is working toward acquiring roundouts to improve the 

functionality of its wetlands.

NGPC developed the Nebraska Legacy Plan 

(Schneider et al. 2005), which is Nebraska’s “Comprehensive Wildlife Conservation Strategy”; such plans 

are required by Congress for all States. The plan was 

developed by a partnership team made up of 20 Federal 

and State agencies, nongovernmental organizations, 

and the Ponca Tribe of Nebraska. This document has 

become the guiding document for conservation groups 

throughout the State. 

The plan identifies the Rainwater Basin as a biologically unique landscape. Key concerns identified 

for this region include the spread of invasive species, 

conversion of natural habitats, alteration of grazing 

and burning regimes, and drainage and sedimentation 

of existing wetlands.

NATURAL RESOURCES CONSERVATION SERVICE 

The NRCS is one of the major partners in wetland 

conservation in the region. Most of its recent work has 

been associated with the national Wetlands Reserve 

Program, a voluntary program to restore wetlands. 

The program has three options for landowners: permanent conservation easements, 30-year conservation 

easements, or a simple cost-share restoration agreement. Lands enrolled in a conservation easement have 

both the wetland and the surrounding upland restored. 

Within the Rainwater Basin, Wetlands Reserve Program contracts scattered across the Rainwater Basin 

Wetland Management District have restored and protected approximately 7,077 acres (Randy Epperson, 

program manager, Natural Resource Conservation 

Service, Nebraska; personal communication; 2011). 

Recently, the NRCS granted a variance to the Wetlands Reserve Program within Nebraska. The variance would allow sellers of conservation easements 

to retain grazing rights. The basis of the variance is 

that grazing is a critical, natural process in sustaining 

shallow, playa wetlands.

In addition, because of the intense agriculture and 

wetland drainage within the Rainwater Basin, the Nebraska office of NRCS in 2010 approved an application 

that requested a variance to allow center pivot irrigation equipment to traverse portions of wetlands and 

uplands protected under the Wetlands Reserve Program. However, numerous wetlands remain drained 

and without conservation protection because farmers 

need to run one or more pivot wheels across a wetland which is generally not allowed under the Wetland 

Reserve Program.

The Farm Service Agency, with technical assistance from the NRCS, administers the CRP (Conservation Reserve Program) which emphasizes support 

for working livestock-grazing operations, enhancement of plant and animal biodiversity, and protection 

of grassland under threat of conversion to other uses 

for a limited duration (10–15 years). Participants voluntarily limit future development and cropping uses 

of the land. At the same time, participants retain the 

right to conduct common livestock-grazing practices 

and operations related to the production of forage and 

seeding, subject to certain restrictions during nesting 

seasons of bird species that are in significant decline 

or are protected under Federal or State law.

NEBRASKA ENVIRONMENTAL TRUST 

By a vote of the people, the Nebraska Environmental 

Trust was established in 1992 to use 44.5 percent of the 

State’s lottery proceeds for the purpose of conserving, 

enhancing, and restoring natural physical and biological environments across the State. During its 19-year 

existence, millions of dollars have been provided toward conservation of wetlands within the Rainwater 

Basin region. The projects funded by the trust have 

included fee and easement acquisition, restoration, 

research, monitoring, and public outreach projects.

TRI-BASIN NATURAL RESOURCE DISTRICT 

Tri-Basin Natural Resource District, located in the 

western portion of the Rainwater Basin, currently 

owns and manages a large wetland and two conservation easements that protect privately owned wetlands. 

In addition, an imposed moratorium on groundwater 

development has prompted the district to begin exploring ways to reduce groundwater use and to increase 

groundwater recharge. One such program would be 

water banking, in which water allocation in one area 

would be transferred to another area. This type of 

program leads the way to having drained wetlands 

restored as marginal farm lands are taken out of irrigation. Other Natural Resource Districts within the 

Rainwater Basin are also looking at ways to better 

manage groundwater use for agriculture.

Habitat Protection and the 

Acquisition Process

Wetland habitat protection would occur through the 

purchase of fee-title and conservation easements. It 

is the long-established policy of the Service to acquire 

minimum interest in land from willing sellers to achieve 

habitat acquisition goals. 

The acquisition authorities for the proposed expansion are the Migratory Bird Hunting and Conservation Stamp Act of 1934, also known as the Duck Stamp 

Act (16 USC 718-718h; 48 Stat. 51, as amended) and 

the Land and Water Conservation Fund Act of 1965 

(P.L. 88-578, Title 16). The Migratory Bird Hunting 

and Conservation Stamp Act money used to acquire 

property is received from Duck Stamp revenue. The 

Land and Water Conservation Fund is derived primarily from oil and gas leases on the Outer Continental 

Shelf, motorboat fuel tax revenues, and sale of surplus 

Federal property.

There could be additional funds to acquire lands, 

waters, or interest therein for fish and wildlife conservation purposes through congressional appropriations, donations from nonprofit organizations, and 

other sources.

The basic considerations in acquiring interest in 

property are the biological significance of a wetland, 

the feasibility of restoring wetland habitat, and landowner interest in the program. Fee-title acquisition 

would focus on two areas: wetland portions that adjoin 

properties in fee title by the Service, and larger semipermanent wetlands located within a wetland complex 

of smaller seasonal wetlands. These properties, once 

acquired, would be managed as WPAs. 

Conservation easements would be purchased in 

perpetuity on privately owned property containing 

smaller wetlands located in cropland and grassland. 

The easements would protect the wetlands from being drained or filled. Surrounding upland buffer areas 

under easement would be planted and remain in grass. 

All other property rights, including grazing, haying, 

and public access would remain with the landowner. 

Purchases would occur with willing sellers only 

and would be subject to available funding.

Chapter 2 — Alternatives, Including the 

Proposed Action

This chapter describes the two alternatives identified 

for this project that were developed according to National Environmental Policy Act (NEPA) § 102(2)(E) 

requirements to “study, develop, and describe appropriate alternatives to recommended courses of action 

in any proposal which involves unresolved conflicts 

concerning alternative uses of available resources.” 

In addition, alternatives that were eliminated from 

detailed study are briefly discussed, including the 

reasons they were not further examined. The following alternatives were analyzed:

■ no-action alternative 

■ proposed action, giving the Service the authority 

to expand its acquisition authority from its current 

level of 24,000 acres to 38,177 acres

The alternatives consider the effects of expanding land 

acquisition within the Wetland Management District 

boundary identified in this environmental assessment.

Alternative A (No Action)

Under alternative A, wetland acquisition would continue until the Service has reached its current authorization of 24,000 acres. After the authorization level 

is reached, any additional acres that would come under 

Service ownership within the Rainwater Basin would 

come from donations or gifts from landowners, conservation organizations, and other government agencies. 

Wetland habitat management and restoration would 

continue on lands owned by the Service to help meet 

the needs of migratory birds. Refuge revenue-sharing 

payments would continue to be made to counties with 

Service lands. 

Under this alternative, many of the privately owned 

wetlands vulnerable to drainage or other destruction 

may be lost. The burden to protect wetlands without compensation would lie more heavily on private 

landowners with a majority of marginal cropland not 

being restored.

Alternative B (Proposed 

Action)

Under alternative B, the Service would increase its 

land acquisition goal from 24,000 acres to 38,177 acres 

within the Rainwater Basin Wetland Management 

District. All lands would be acquired from willing sellers, with acquisition occurring over as many years as 

necessary to reach the new goal.

The Service would seek to purchase an additional 

9,177 acres in fee title and 5,000 acres in conservation 

easements over the existing goal. Lands targeted for 

acquisition would be according to a prioritization system established by the Rainwater Basin Joint Venture. 

This system was developed by biologists from different agencies and organizations to identify and ensure 

protection of those wetlands that best meet the biological needs of migratory waterfowl and shorebirds. 

Within the rating system, fee-title acquisition will 

meet one of two criteria: privately owned portions of 

wetlands adjoining existing WPAs and large wetlands 

that are part of a complex of numerous small wetlands. 

Conservation easements purchased from willing sellers would focus on small wetlands that are part of a 

large complex of wetlands. 

Lands purchased in fee title would be managed as 

WPAs and be open to public use. 

Conservation easements purchased from willing 

sellers would prohibit destruction of wetland habitat. In addition, the surrounding upland included in 

the easement would be required to be maintained as 

grassland. The landowner would retain access, grazing, and haying rights. Easements would be managed 

by the Watershed Management District. Monitoring 

would include periodic reviews of land status through 

correspondence and meetings with landowners or land 

managers to ensure that the stipulations of the conservation easement are being met. Photographs would 

be taken at the time the easements are established to 

document baseline conditions.

Refuge revenue sharing would be paid to counties 

for Service lands in fee-title ownership. Taxes on lands 

containing a conservation easement would continue 

to be paid by the landowner. 
12 Draft EA, Rainwater Basin Wetland Management District Expansion

Alternatives Considered but 

Not Studied

There was no further analysis conducted for the following two alternatives for the reasons described below.

WETLAND PROTECTION AND ENHANCEMENT 

THROUGH PARTNERSHIPS

One alternative considered was developing a program 

similar to CRP that would pay landowners for protecting their wetlands from being altered or destroyed for 

a period of 10 years. The contract would be available 

for renewal every 10 years. This alternative would not 

ensure the protection of wetlands for the long term. 

Like CRP lands, wetlands would become vulnerable 

to drainage when crop prices make it profitable to 

convert such wetlands to cropland. Furthermore, the 

Service has an active Partners for Fish and Wildlife 

Program in the area, which can be used if acquisition 

is not an option for a landowner.

COUNTY ZONING

In a traditional approach used by counties and municipalities, the local government would use zoning 

as a means of designating what type of development 

could occur in an area. Nebraska law grants cities and 

counties the authority to regulate land use, and engaging in planning and zoning activities is therefore 

optional. However, zoning may be subject to frequent 

changes and would not ensure the long-term protection of wetlands. 
Chapter 3 — Affected Environment

Physical Environment

CLIMATE

The region’s climate is semiarid, with annual precipitation ranging from 21 to 28 inches (west to east). Annual evaporation for small bodies of water averages 

46 inches; about 77 percent of that amount is lost from 

May through October. Most of the precipitation occurs 

in the springtime and during summer thunderstorms. 

Heavy rains fill the wetlands, but quickly dry in a matter of a few weeks. Wind scouring of wetland bottoms 

has removed the finer silts and loam soils, while the 

heavier silt clays remain in the wetland bottoms. In 

some wetlands, the impervious clay layer that has 

formed extends as deep as 72 inches.

CLIMATE CHANGE 

Current climate change projections for the Great Plains 

are for warmer temperatures and increased precipitation. The increase in precipitation is expected to be 

quite variable across the Great Plains and will be less 

than that needed to offset the increase in temperatures. The result will likely be warmer, drought-like 

conditions. Intense precipitation events are projected 

to increase, causing more runoff, pollution, and soil 

erosion problems. Droughts and floods are expected 

to occur more frequently. The problems caused by climate change will be further compounded by invasive 

species that will be able to adapt quickly to fluctuating extreme water conditions. 

ADAPTATION, MITIGATION, AND ENGAGEMENT

The Service’s strategic response to climate change involves three core strategies: adaptation, mitigation, and 

engagement (USFWS 2009). Through adaptation, the 

impacts of climate change on wildlife can be reduced 

by conserving habitats expected to be resilient. The 

Rainwater Basin Expansion Project would provide 

an anticipatory, rather than a reactive, response. As 

preserving migratory corridors becomes increasingly 

important, the Rainwater Basin will continue to provide a stopover area for shorebirds and waterfowl 

within the central flyway. 

Waterfowl use of the area may increase significantly 

because most of its precipitation occurs in late winter 

and early spring and because of the greater intensity 

of precipitation events. Another factor that may play 

a significant role in bird use will be the anticipated decline in precipitation and wetlands in other portions 

of the country.

Carbon sequestration forms one of the key elements 

of mitigation. The Rainwater Basin Expansion Project 

would have a mitigating effect on climate change by 

capturing carbon. Wetlands that are currently drained 

and being farmed at the time of purchase would be 

restored to wetland habitat. Surrounding upland buffer areas would be restored to native warm-season 

grasses and forbs. Prairie vegetation stores carbon in 

its deep fibrous roots, with approximately 80 percent 

of the plant biomass located below ground. Since the 

land would no longer be farmed, a large amount of 

carbon is expected to be sequestered. 

Engagement involves cooperation, communication, 

and partnerships to address the conservation challenges presented by climate change (USFWS 2009). 

The Rainwater Basin Expansion Project would serve 

as a model for engagement by working with farmers 

and landowners; nongovernmental organizations such 

as The Nature Conservancy, Ducks Unlimited, and 

Pheasants Forever; State and local agencies such as 

the NGPC and local Natural Resource Districts; and 

Federal agencies, including the NRCS.

GEOLOGIC RESOURCES

The Rainwater Basin lies in the flat to gently rolling, 

mixed-grass, loess plains of south-central Nebraska. 

This area is geologically new and has not developed 

a complete system of streams to drain surface water. 

It is from this characteristic that the area received 

its name: Rainwater Basin. 

Wind-deposited Peorian Loess occurs extensively 

across the basin and has been stable for about 10,000 

years (Keech and Dreezen 1959). Upland soils that 

formed in wind-deposited material include Crete, 

Hastings, Holdrege, Hord, and Uly (Kuzila 1984). The 

soils are suitable for farming, with about 80 percent 

of the land being planted with crops. The shallow, flat 

depressions formed predominately by wind scouring are often referred to as playa wetlands because 

of their formation process and ephemeral (water 

levels lasting for a brief time) nature. Radiocarbon 

dating indicates the wetlands were created near the 

end of the Ice Age, 20,000 to 25,000 years ago. Some 

depressions may have been enlarged and new ones 

created as recently as 3,000 years ago (Farrar 1996). 
14 Draft EA, Rainwater Basin Wetland Management District Expansion

Over thousands of years, minute clay particles accumulated in the bottoms of the depressions, allowing 

water to pond above the soil surface. The impervious 

clay layers are 6 to 72 inches thick. The wetland soils 

are predominantly Butler, Fillmore, Scott, and Massie 

(Kuzila and Lewis 1993, Kuzila 1994). 

HABITAT

History of Land Development 

In contrast to the thick clay in the depressions, the 

upland soils are very productive silts and loams used 

for agriculture. At the end of the 1800s, the rich soil 

was being cultivated, and by the 1910s, larger wetlands were being converted to cropland. In the 1950s, 

irrigation canals and large-volume wells expanded 

gravity-flow irrigation, causing smaller wetlands to 

be filled and their watersheds to be reshaped.

Water concentration pits were constructed to collect irrigation runoff at the lowest parts of the fields 

in areas that would normally be wetlands. The pits 

were an effective way to both drain a wetland and 

gain excavated material to fill the remaining portion 

of the wetland. The use of concentration pits was extensive. The Service identified 11,859 concentration 

pits totaling 7,506 acres within the Rainwater Basin 

in 2004 (USFWS, Grand Island GIS Shop, unpublished). Their water storage capacity is estimated to 

be about two-thirds of the region’s historic wetland 

storage capacity. 

A 1984 (Schildman and Hurt 1984) wetland survey 

estimated that approximately 4,000 wetlands existed 

that totaled over 100,000 acres. More recent soil surveys, however, estimate that the original number of 

wetlands was much higher and covered about twice 

that number of acres.

In the early 1970s, the loss of wetlands further increased with the development of center pivot irrigation technology. Pasture ground containing wetlands 

was broken up, drained, and combined with other 

cropland to form large (160-acre) fields that would 

support center pivots. The 2004 assessment estimated 

that only 16 percent (1,693) of the historic wetlands 

retained some wetland function. Those wetlands total 

about 38,500 acres. 

Many of the former wetlands were intentionally 

leveled or have been filled with culturally accelerated 

sediment. Nearly all the remaining wetlands have been 

affected by surrounding land use. Most of the effect 

has been the reduction of the watershed’s ability to 

provide enough water to allow the wetlands to function naturally. As more upland has been converted 

to cropland, sedimentation caused by runoff has increased. In the last 40 years, the use of chemicals and 

fertilizers in crop production has brought pesticides 

and high levels of nutrients into the wetlands. 

Wetlands in larger watersheds used to retain water on a semipermanent basis. Now with reshaping 

of the landscape, creation of roads and ditches, sedimentation, and cultivation practices, even unaltered 

wetlands cannot function properly and most of them 

are becoming more ephemeral.

The loss of pastureland not only affected water quality from runoff, it effectively reduced livestock available for grazing remaining wetlands. Wetlands that 

once supported livestock grazing and remained open 

for waterfowl became choked with cattail and bulrush. 

Past Wetland Protection and Land Use within 

Watersheds 

Challenges related to wetlands go beyond what is 

actually happening within each wetland. Many of the 

problems are associated with surrounding land uses. 

Those uses include intense cultivation, land leveling, 

large livestock confinement areas, and lack of grazing livestock. 

Cultivation of upland areas increases soil erosion 

and sedimentation of wetlands, a process that has 

been going on in some areas for more than 150 years. 

Runoff and erosion also transport pesticides and nutrients to the wetlands. In some larger watersheds, 

seasonal heavy rains are known to occur with enough 

intensity that residual cornstalks are transported to 

ditches and waterways. Restoration work on these 

wetlands often includes sediment removal, especially 

near the fluvial area of waterways. 

Land leveling, as discussed earlier, began with the 

conversion from dryland farming to gravity flow irrigation. Effective gravity-flow irrigation requires a 

uniform, gentle slope across the field to allow water 

released on the upper end of the field to flow gently 

down toward the lower end. Any wetland or depression in the middle of the field that pooled water was 

filled. The common practice was to dig large water 

concentration pits to collect any water that reached 

the lower end of the field. Soil material removed from 

the pit was used to fill the remaining portion of the 

wetland to allow more area to be farmed. The result 

of this practice was that only the larger wetlands that 

could not be economically filled or drained remained 

as wetlands. 

The ability of many of the remaining wetlands to 

function deteriorated. Sedimentation reduced water depth, loss of portions of the watershed’s runoff 

shifted wetlands toward more seasonal water retention, aquatic vegetation increased, and, with the absence of grazing livestock, the wetlands became more 

choked with monotypic stands of cattail, bulrush, and 

reed canarygrass. 

The availability of corn for feed and profitability 

encouraged large livestock confinement facilities. 

Many were built on poorer, steeper land—often in close 

proximity to a wetland. Although State regulations 
15

control most of the contaminant concerns, large runoff 

events and violations sometimes place these contaminants in wetlands.

Wetland drainage and conversion is the main threat 

to the Rainwater Basin wetlands. Over the past decade, wetland loss from drainage and filling has been 

extensive. Wetland drainage was widespread even 

before efforts were made to determine the number 

of wetlands that existed in the region. 

Estimates of the number of historical wetlands are 

based primarily on soils maps, which show the extent 

of hydric soils on the landscape. That estimate is 11,000 

historical wetlands totaling 204,000 acres (USFWS, 

Grand Island GIS Shop, unpublished). GIS analysis 

and high-resolution aerial photography allow for an 

accurate measure of wetland acres. Current estimates 

are that 38,500 acres of wetlands remain. The number 

of functional wetlands has declined to 1,693 (2004 data, 

USFWS, Grand Island GIS Shop, unpublished). This 

is about 16 percent of the historical number.

Each year, the slow degradation of wetlands continues. Shallow depressions that are being farmed are 

slowly filling with sediment from the adjacent upland. 

Years of farming and pesticide application have adversely affected native vegetation and invertebrates. 

Farming practices such as no-till farming reduce the 

amount of soil erosion, but may also reduce the amount 

of water runoff reaching the depression. 

Most of the larger wetlands have been fully or 

partially drained. Those that have retained some 

functionality are slowly being subjected to the same 

forces as the smaller depressions: sedimentation, 

agricultural chemical runoff, and decreased surface 

water running into the wetland. Years of no farming 

or grazing encourages invasion by reed canarygrass, 

cattail, bulrush, and trees. In general, lack of grazing, 

burning, and disturbance greatly reduces the value of 

the wetland for migratory birds. Wetlands that retain 

a higher level of functionality still capture enough of 

the watershed’s runoff to provide aquatic vegetation, 

invertebrates, and water for migrating birds, but 

these remaining wetlands are being subjected to the 

same adverse effects as the more disturbed wetlands. 

An additional threat to some of the wetlands is 

nutrient and waste runoff from large livestock confinement areas. Animal waste in feedlots is hauled to 

surrounding fields. Although State regulations are in 

place to control runoff, heavy rain events can cause 

rapid runoff carrying waste and chemicals that reach 

wetlands. Since the wetlands are within a closed drainage, the nutrients and pollutants are not flushed out 

but accumulate within the wetlands. 

There are many factors driving the continued 

conversion of wetlands within the Rainwater Basin. 

The assumption is that the wetlands that were easy 

and economically feasible to drain have already been 

drained and converted. Each year, however, additional 

wetlands are lost. Some of the common causes for the 

continuing loss of wetlands are changes in Farm Bill 

regulations, commodity prices, increased crop insurance subsidies, and new irrigation and farming technologies. Commodity prices and crop insurance serve 

as a safety net for farming the more risky lands. New 

irrigation technologies allow for chemigation, control 

of water delivery, and easier access across wet areas 

and steeper slopes. No-till farming allows for more economical farming in more arid areas than were possible 

in years past. In recent years, impending moratoriums 

on groundwater development have stimulated developers and producers to convert more land to cropland.

Property taxes, low livestock prices, and low production rates from dryland farming cause landowners to continually look for ways to make every acre 

financially productive, reducing the incentive to keep 

a privately owned wetland. 

The conversion of wetlands and grassland has also 

caused birds to concentrate into fewer areas, increasing the risk of disease outbreaks and competition for 

natural foods. Waste grain has replaced much of the 

natural foods in waterfowl diets. Although corn meets 

the caloric requirements, it is deficient in many of the 

nutrients found in natural foods (Baldassare and Bolen 

1994, Krapu et al. 2004). 

Current Protection Status 

Service acquisition has focused on purchase and protection of the larger wetlands. Over the decades, as 

the smaller surrounding wetlands have been lost, 

the wetlands purchased by the Service have become 

isolated. In some portions of the Rainwater Basin, 

acquisition needs to focus on protecting the smaller 

wetlands that make up a complex, while other portions 

need a larger core wetland to be restored to create a 

complex. Figure 4 shows the change in spatial distribution of wetlands throughout the region (USFWS, 

Grand Island GIS Shop, unpublished).

From 2000 to 2008, aerial surveys were conducted 

every spring by the station biologist to document the 

amount of migratory bird habitat available. A total 

of 17,984 acres of public wetlands were surveyed. 

Of that total, the average amount of suitable habitat (described as any habitat containing water) was 

5,582 acres. This means that an average of 32 percent 

of the public wetland acres were suitable migration 

habitat. Some of those wetlands were supplemented 

with groundwater pumped by the Rainwater Basin 

Wetland Management District and the NGPC. 

Groundwater 

Most of the groundwater in the Rainwater Basin area 

has little or no influence on maintaining wetland water levels. The majority of the groundwater is located 

more than 50 feet underground and in some areas the 

groundwater is more than 400 feet deep. One area east 

of the Tri-County canal has groundwater levels that 

Chapter 3 — Affected Environment 
16 Draft EA, Rainwater Basin Wetland Management District Expansion

are less than 50 feet deep due to artificial groundwater 

mounds that have developed near the surface (Ekstein 

and Hygnstrom 1996).

The development of center pivot irrigation in the 

last third of a century has placed a great demand on 

the groundwater underlying Rainwater Basin. Irrigation, compounded by extensive drought, has caused 

the State legislature to pass legislation to help control 

groundwater declines. Only the extreme western edge 

of the Rainwater Basin Wetland Management District 

lies within an over-appropriated Natural Resource District. Some of the Natural Resource Districts located 

within the Rainwater Basin, however, have placed a 

moratorium on new wells and are requiring stricter 

monitoring of pumping. 

There is some groundwater recharge below Rainwater Basin wetlands. Percolation occurs as macropore 

flow through desiccation cracks that form during dry 

conditions (Wilson 2010). However, soil percolation decreases as clays expand and fill the desiccation cracks 

(Wood 2000, Wilson 2010). Research from playa lakes 

in Texas and New Mexico showed similar recharge 

characteristics (Wood 2000).

Artificially pumping groundwater into the wetlands 

has made a dramatic difference in amount of habitat 

on WPAs. The average suitable habitat for WPA wetlands not pumped was 22 percent of the total wetland 

acres. For WPA wetlands pumped, the average suitable habitat was 39 percent of the total wetland acres.

Biological Environment

WILDLIFE

Rainwater Basin serves as a critical resting and feeding stopover area for millions of waterfowl during 

spring migration. It is estimated that waterfowl using 

the area each spring include 7.5 million ducks and 2.1 

million geese. Gersib et al. (1989) documented that 50 

percent of the mid-continent mallards and 30 percent 

of the continental northern pintails migrate through 

during spring migration. Nearly 90 percent of the midcontinent population of greater white-fronted geese 

has been documented to use this region during their 

spring migration.

A total of 329 species of birds have been observed 

within the Rainwater Basin, including 41 species of 

shorebirds and 35 species of waterfowl. Between 

200,000 and 300,000 shorebirds migrate through in the 

spring. Common grassland species include northern 

harrier, northern bobwhite, ring-necked pheasant, 

greater prairie-chicken, dickcissel, western meadowlark, bobolink, field sparrow, and grasshopper sparrow. 

Spring migration usually starts with a buildup of 

Canada geese on the Platte River until the Rainwater 

Basin wetlands begin to thaw. Snow geese, greater 

white-fronted geese, and mallards begin to peak by 

mid- to late February. In early March, northern pintail 

numbers peak, followed by Ross’s geese and greenwinged teal. The remaining divers and puddle ducks 

usually peak during mid- to late March. 

Most shorebirds pass through between April 15 

and May 15. According to Jorgensen (2004), the most 

common spring shorebird migrants include blackbellied plover, American golden-plover, semipalmated 

plover, greater yellowlegs, lesser yellowlegs, willet, 

upland sandpiper, Hudsonian godwit, dunlin, whiterumped sandpiper, Baird’s sandpiper, semipalmated 

sandpiper, least sandpiper, stilt sandpiper, short-billed 

dowitcher, long-billed dowitcher, buff-breasted sandpiper, Wilson’s snipe, and Wilson’s phalarope. Rainwater Basin has the largest known concentration of 

buff-breasted sandpipers during spring migration 

(Jorgensen 2007). Common late-summer migrants 

are greater and lesser yellowlegs, solitary sandpiper, 

upland sandpiper, pectoral sandpiper, semipalmated 

sandpiper, least sandpiper, stilt sandpiper, long-billed 

dowitcher, and Wilson’s snipe. 

Rainwater Basin is identified as a landscape of 

hemispheric importance by the Western Hemisphere 

Shorebird Reserve Network. It also lies within the Geographic Framework of Bird Conservation Region #19.

Peregrine falcons frequent wetlands during peak 

shorebird migration periods. Prairie falcons, on the 

other hand, are most numerous in late winter when 

horned larks and meadowlarks are common. Merlin 

are primarily winter visitors and spring migrants 

(Johnsgard 1997). Bald eagles are most common during peak waterfowl migration. Burrowing owls nest 

on isolated prairie dog towns. Cinnamon teal are rare, 

but are occasionally seen in the basin. Harris’s sparrows can be seen on the eastern wetlands that have 

brushy growth or plum thickets. 

Threatened and Endangered Species 

Three species listed under the Federal Endangered 

Species Act and the Nebraska Nongame and Endangered Species Conservation Act use the Rainwater 

Basin wetlands during migration: the State and Federally endangered whooping crane and least tern, and 

the State and Federally threatened piping plover. 

Forty-two percent of confirmed whooping crane 

observations in Nebraska have been at Rainwater 

Basin wetlands (Richert 1999). Most of these sightings 

occur during the first two weeks of April or from late 

October through mid-November. Piping plovers are 

rarely seen on Rainwater Basin wetlands due to their 

size and the number of other shorebirds that would be 

using mudflat habitats in late April through mid-May 

(Johnsgard 1997). Least terns have even been documented at some basins, although their occurrence in 

the Rainwater Basin is rare.

18 Draft EA, Rainwater Basin Wetland Management District Expansion

Other species that are proposed or are candidates 

for listing under the State and Federal Endangered 

Species Acts or are species of concern that use the 

Rainwater Basin include northern harrier, Swainson’s 

hawk, ferruginous hawk, long-billed curlew, black tern, 

short-eared owl, and Sprague’s pipit.

Mammals 

Large mammals common to the region are those associated with grasslands of the Great Plains. They 

include white-tailed deer, coyote, raccoon, striped 

skunk, eastern cottontail, American badger, and Virginia opossum. Mule deer have occasionally been seen 

in the western portion. Muskrat and mink occur during wetter years but their populations have dropped 

dramatically with changes in land use and wetlands. 

Isolated prairie dog towns are scattered throughout 

the region, with most of them smaller than 40 acres 

and located on public lands. Common small mammals 

include thirteen-lined ground squirrel, northern and 

plains pocket gopher, Ord’s kangaroo rat, meadow 

jumping mouse, meadow vole, northern grasshopper 

mouse, and white-footed mouse. Less common mammals are red fox, black-tailed jackrabbit, woodchuck, 

Franklin’s ground squirrel, and eastern fox squirrel. 

Reptiles and Amphibians 

Semipermanent wetlands provide habitat for painted 

and snapping turtles. Ornate box turtles may be found 

in grassland areas. Western garter snakes, bull snakes, 

and eastern yellowbelly racers are fairly common. 

Western hog-nosed snakes are less common and prefer 

dry sandy prairies. Smooth green snake and redbelly 

snake are rare in the region. The lesser earless lizard 

may occur in open sandy soil with sparse vegetation, 

while the six-lined racerunner can be found in both 

lowland and upland sites.

Amphibians that occur in the Rainwater Basin include plains spadefoot toad, Woodhouse’s toad, Great 

Plains toad, Blanchard’s cricket frog, boreal chorus 

frog, bullfrog, gray treefrog, plains leopard frog, and 

tiger salamander.

Fisheries Due to the hydrologic nature of the wetlands within the Rainwater Basin, there currently 

are no viable fisheries. Two native Missouri River 

basin cyprinids, the shoal chub and plains minnow, 

are of concern but have no legal protected status in 

Nebraska. Catfishes, sunfishes, darters, catastomids, 

and other minnows are part of the fish communities in 

this region that are also of concern and of interest to 

the National Fish Habitat Action Plan partnerships.

Cultural Resources

Archaeological and Native dwelling remains representing 12,000 years of human occupation have been found 

in the Rainwater Basin. Although there have been 

few formal investigations done in the area, evidence 

from the earliest paleo-Indian occupation through the 

rural and agricultural development of the early 20th 

century has been located in a variety of geographical 

settings. Although these sites exhibit a wide range 

of artifacts and features, definite trends in site types 

and changes through time are apparent. 

Current archaeological evidence indicates that the 

earliest humans, called paleo-Indians, migrated to the 

region near the close of the Ice Age approximately 

12,000 years ago. These people had a highly mobile 

lifestyle that depended on the hunting of big game, including mammoths and a species of huge, now-extinct 

bison. The hallmark of most paleo-Indian sites are the 

beautiful but deadly spear points that are generally 

recovered from animal kill and butchering sites and 

small temporary camps. Three late paleo-Indian sites 

in Frontier County, just to the west of the Rainwater 

Basin, date from 10,000 to 8,000 years ago and have 

provided the best evidence of actual living areas. Another well-known paleo-Indian site, the Meserve site, 

dating to approximately 9,400 years ago, is located in 

Hall County within the Rainwater Basin.

There was a gradual but definite shift in the pattern of human use of the area beginning about 8,000 

years ago. The changes were due to a combination 

of climatic fluctuations and an increasing population, 

coupled with tremendous social change and technological innovation. This stage is referred to as the 

Archaic stage and lasted until about 1,500 years ago. 

Although the Archaic stage is better represented in 

the archaeological record than the preceding paleoIndian stage, interpretation of the remains is difficult. 

Evidence of a greater diversity of tools and increased 

use of native plants is found on many sites, but the 

remains also suggest a more localized and less mobile 

population. 

By 2,000 years ago, the populations of the area 

became increasingly influenced by the woodland cultures to the east. This period, referred to as the Plains 

Woodland period (2,000 to 1,000 years ago), brought 

great changes and innovation, including the advent 

of pottery, the bow and arrow, and semipermanent 

dwellings. Small villages began to be established, and 

evidence of early agriculture has been found along 

some of the waterways. 

Evidence of an increasingly sedentary population 

from approximately 1,000 years ago until approximately 400 years ago is found at many of the sites. 

This adaptation is referred to as the Central Plains village tradition and amplifies many of the trends began 

during the Plains Woodland period. Small villages of 

earthen structures with associated agricultural fields 

became more common. The increased use of pottery 

in conjunction with the construction of food storage 
Chapter 3 — Affected Environment 19

pits reflect a population that was spending increasing 

amounts of time in one location. 

Early postcontact occupation of the area (400 to 

100 years ago) included the Pawnee with the Arikara, 

Arapaho, Cheyenne, Lakota, Oto, and Kansas peoples. 

Their settlements tended to be large villages with 

extensive agricultural fields and were often located 

along the major waterways. Bison hunting, fishing, 

and Euro-American trade were also primary components of the economy. Beginning in the early 1700s, 

explorers began to make incursions into the area and 

by the mid-1800s, there was a regular stream of emigrants passing through on their way west. Many of 

these travelers chose to stay and settle in the area 

referred to today as the Rainwater Basin.

Socioeconomic Environment

LANDOWNERSHIP

The project area includes all or portions of 13 counties: Adams, Clay, Fillmore, Franklin, Gosper, Hall, 

Hamilton, Kearney, Phelps, Polk, Saline, Seward, and 

York. The total population of these counties is almost 

182,000 people, or roughly 10 percent of Nebraska’s 

population (U.S. Census Bureau 2010). Numerous small 

communities of less than 1,000 people exist throughout 

the area. The five largest commercial hubs are Grand 

Island, Hastings, York, Holdrege, and Minden. The 

city of Kearney lies outside the Rainwater Basin immediately north of Kearney County. 

The population trend within the Rainwater Basin 

follows the trends seen throughout the State. From 

1980 to 2002, the number of farms in the Rainwater 

Basin region dropped from 4,585 to 3,280, representing a 28.5 percent decline, with the farms becoming 

larger (Nebraska Agricultural Statistics Service 2003). 

Between 2002 and 2007, the number of farms within 

the 13 Rainwater Basin Wetland Management District 

counties dropped by 6.3 percent, and the average farm 

size increased by 195 acres (USDA 2007). 

During the years 2000 to 2010, the collective population of the counties in the Rainwater Basin increased 

by 1.0 percent (U.S. Census Bureau, 2010). The increase, however, was not uniform. Counties without 

a large commercial hub (9 of the 13 counties) showed 

significant declines. Fillmore and Franklin Counties 

each experienced about an 11 and 10 percent decline, 

respectively. Hall County, containing the city of Grand 

Island, showed nearly all of the gain (figure 5). 

The well-being and stability of the small communities have depended on the farming economy, primarily 

irrigated corn and soybeans. As land becomes more 

concentrated in larger farm operations, fewer families 

remain in small communities to support businesses, 

schools, and churches. The trend is for people to move 

to larger nearby commercial hubs.

Approximately 1.6 percent of Nebraska is in either 

State or Federal ownership (U.S. Census Bureau, 

1991). Only Iowa and Kansas have less government 

Figure 5 . Change in county population size in the Rainwater Basin from the 2000 to 2010 census .
20 Draft EA, Rainwater Basin Wetland Management District Expansion

ownership by percentage. Within the Rainwater Basin, 

agriculture (79.9 percent cropland and 10.5 pasture or 

CRP) is the dominant land use (USFWS, Grand Island GIS Shop, unpublished). Roads or communities 

make up 5.4 percent of the land area. Fish and Wildlife Service lands within the region total 23,855 acres, 

representing about 0.6 percent of the region. Clay 

County, with the U.S. Department of Agriculture’s 

35,000-acre Roman L. Hruska Meat Animal Research 

Center, has a higher percentage of Federal ownership 

than the other Rainwater Basin counties. Located 

west of Clay Center, Nebraska, the research center 

is the largest federally owned property in the project 

area. Nonfarmed wetlands represent 1 percent of the 

land use. See the Habitat section in Chapter 3 for additional information about agricultural development. 

PROPERTY TAX

Property tax is assessed on each property owner 

within each county. The amount is derived from the 

value of each parcel of land, based on the reasonable 

highest and most probable use. The assessed value of 

agricultural land is no more than 75 percent of market 

value (NEDOR 2011). 

The inflation in land value in recent years has caused 

taxes on agricultural land to go up disproportionately 

compared with nonagricultural property, such as homes 

within communities. For counties with low populations 

and few commercial properties, agricultural lands may 

represent well over half of the county’s total assessed 

value. As costs in low-population counties continue to 

go up, populations go down, and because no new industries are being created, agricultural land claims a 

higher percentage of the county’s total assessed value, 

placing more of the burden of financing the county on 

the shoulders of farmers.

PUBLIC USE AND WILDLIFE-DEPENDENT 

RECREATIONAL ACTIVITIES

For much of the past century, access to private property was relatively easy to obtain. Most of Nebraska’s 

population was somehow connected to the land, either 

by family or by acquaintances. Hunting was seen as 

recreation that provided little opportunity for revenue to the landowner, and access was freely granted 

as a neighborly gesture. In the past few decades, this 

trend has changed. Urban populations are no longer 

closely connected to the land, and access to private 

land is more commonly being denied or allowed only 

on a fee basis. 

The result is that the public is relying more on 

public lands for wildlife-dependent recreation. Within 

Rainwater Basin, 32 Wildlife Management Areas are 

managed by the NGPC, and the Service manages 59 

WPAs. A total of 31,823 acres is available for public use 

(USFWS, Grand Island GIS Shop). Pheasant hunting 

is the most common recreational activity, followed by 

waterfowl hunting and birdwatching. It is estimated 

that 81,880 use-days are spent annually on waterfowl 

and upland bird hunting on State and Federal properties in the Rainwater Basin (Mark Vrtiska, biologist, 

NGPC; personal communication; May 12, 2010). 
Chapter 4 — Environmental 

Consequences

This chapter assesses the environmental impacts expected to occur from the implementation of alternatives A and B, as described in Chapter 2. 

Effects on the Biological 

Environment

This section describes the effects on wildlife habitat 

and water and soil resources of carrying out alternatives A and B.

WILDLIFE HABITAT—ALTERNATIVE A (NO 

ACTION)

Under alternative A, land acquisition by the Service 

would continue until the original authorization level 

of 24,000 acres is reached. At that time, future wetland acquisition would depend on other conservation 

agencies and nongovernmental organizations. Since 

the existing authorization limits only the purchase of 

property, the Service would continue to accept gifts 

from other entities. For example, the Service could 

enter into an agreement with a donor to accept ownership of a piece of property to be managed as part of 

the National Refuge System. 

Most of the Rainwater Basin wetlands have been 

determined to be nonjurisdictional wetlands under the 

Clean Water Act as it is currently being administered. 

The U.S. Department of Agriculture’s Swampbuster 

Act does not prohibit alteration of wetlands, but it 

withholds Federal farm program benefits from any 

person who plants a commodity crop in a wetland that 

has been converted. Changes in agricultural economics 

would continue to influence the existence of privately 

owned wetlands. Over a period of time, total wetland 

acres and quality are expected to decline under alternative A. Migratory waterfowl use the numerous 

shallow, temporary wetlands for feeding and resting, 

but prefer the larger nearby wetlands for roosting. 

As the presence of temporary wetlands declines, the 

value of larger wetlands located in a wetland complex 

would decline due to fewer food resources. 

Wetlands with split ownership between the Service 

and private landowners would likely remain unrestored 

because complete restoration would be less likely due 

to conflicting land uses. These wetlands could also be 

under-managed, because in many cases the portion 

of wetlands in private ownership would remain idle 

and become dominated by late-successional wetland 

plants that provide little to no benefit to migratory 

waterfowl. The Service would continue to work with 

neighboring landowners to manage these areas for 

waterfowl. Participation level, however, would be 

expected to remain low. 

Waterfowl nutritional needs derived from natural wetland foods would remain unmet. As little as 

14 percent of the waterfowl diet, as estimated by the 

Rainwater Basin Joint Venture, would come from 

wetlands under this alternative. The remainder would 

continue to come from waste grain, which does not 

provide needed amino acids and minerals. Over time, 

as more wetlands are lost, the percentage of natural 

foods in waterfowl diets would be expected to decline 

even further.

Because any decline in roosting areas would cause 

bird populations to become more concentrated on the 

remaining wetlands, the potential for a major avian 

disease outbreak would remain high and would be 

expected to increase over time. Groundwater pumping would be expected to play a more critical role in 

keeping birds dispersed throughout the region. 

WILDLIFE HABITAT—ALTERNATIVE B (PROPOSED 

ACTION)

Under alternative B, the expansion of land acquisition 

across the Rainwater Basin would ensure that critical 

wetlands are protected in perpetuity. It would allow 

the Service greater flexibility to consider fee-title or 

easement acquisition as potential land management 

strategies. GIS modeling would help to identify wetlands with key biological characteristics that are best 

suited for fee-title and easement acquisition. This approach would help to ensure that funding is directed 

to where it can provide the most benefit to priority 

species. 

Purchase of roundout properties would in many 

ways multiply the benefits of the wetlands beyond 

what they currently provide in split ownership. It 

would be easier to use management strategies such 

as grazing, prescribed burning, restoration, and water 

management. The Service would continue to partner 

with neighboring landowners to enhance privately 

owned wetlands for the benefit of migratory birds. 

Natural foods from wetlands would increase, bringing the Rainwater Basin Joint Venture closer to its 
22 Draft EA, Rainwater Basin Wetland Management District Expansion

goal of having 28.2 percent of waterfowl energetic 

needs being met by natural foods rather than waste 

grain. Birds would be expected to leave the Rainwater 

Basin region in better body condition, which would in 

turn mean better production on their northern nesting grounds.

The potential for a major avian disease outbreak 

would be reduced as more wetlands would be better managed for waterfowl migrations. Pumping and 

other forms of water management would remain as 

management options.

Acquisition and protection of wetlands within the 

Rainwater Basin will indirectly provide improved water quality to the headwaters of several streams (e.g., 

Big Blue and Little Blue) that provide fish habitat. 

WATER AND SOIL RESOURCES—ALTERNATIVE A 

(NO ACTION)

Under alternative A, water quality and quantity would 

decline and sedimentation would increase over time. 

It is expected that future wetland loss would increase 

agricultural and sediment runoff. Runoff flowing out 

of watersheds would increase, thereby increasing erosion and nutrient loading. The ability of altered wetlands to contribute to groundwater recharge would 

also decline.

WATER AND SOIL RESOURCES—ALTERNATIVE B 

(PROPOSED ACTION)

Under alternative B, wetlands that are protected in 

perpetuity would exist for the long term, providing 

many of the benefits attributed to wetlands, including entrapment of agricultural fertilizers, chemicals, 

and sediment. Wetland plants would help convert 

fertilizers and other farm chemicals into nonpolluting forms. The preserved wetlands would continue to 

provide groundwater recharge to a currently declining groundwater table.

Effects on the 

Socioeconomic Environment

The socioeconomic impact of land acquisition within 

the Rainwater Basin counties is hard to measure with 

a high degree of certainty. What is known is that there 

would be reduction in agricultural production and tax 

revenue associated with Federal acquisition. What is 

poorly determined or immeasurable are the environmental and social benefits provided by wetlands, especially those located in close proximity to each other 

or near a community. Economists often refer to these 

benefits as nonexcludable (available to all) goods that 

have a value to the public that exceeds its value to the 

landowner. For Rainwater Basin wetlands, this value 

extends beyond the local residents to a much larger 

area. For example, the birds that use the Rainwater 

Basin during spring migration are of international 

value for birdwatching and hunting. 

Some local residents perceive themselves as having 

to unfairly shoulder the burden of maintaining these 

wetlands for the benefit of others. Their concerns 

are expressed in the belief that Service acquisition of 

wetlands contributes to declining county populations, 

increasing land prices and taxes. 

POPULATION DECLINE

A review of population changes within counties located 

in the Rainwater Basin between 2000 and 2010 shows 

that the greatest decline has been in counties with 

low (<10,000) populations (U.S. Census Bureau 2010). 

Fillmore County, which does not have a large 

commercial hub, showed the greatest reduction in 

population (11 percent), declining by 744 people from 

2000 to 2010. In contrast, those counties with a larger 

commercial hub showed an increase in population. 

Hall County, which includes the community of Grand 

Island, showed over a 9 percent increase during the 

same period, increasing by 5,073 people. This trend in 

population shift among counties was common throughout the State, where counties with small populations 

and small commercial hubs showed a decrease while 

counties with larger populations and larger commercial hubs showed an increase. 

Even though some residents are concerned that 

Federal acquisition may lead to a decrease in population, there does not appear to be a correlation between 

the two. Clay County, for example, showed a population 

decline of over 7 percent between 2000 and 2010. During that period of time, only 32.5 acres were acquired 

by the Service. A comparison of Clay County with a 

nearby county of similar population without Federal 

lands would help determine if Service ownership may 

be a contributing factor. A comparable county would 

be Antelope County. It does not have a large commercial hub or Federal lands, and it showed a decline of 11 

percent. Other Nebraska counties that met the same 

criteria as Antelope County showed similar trends.

RISING LAND PRICES

Regarding the concern that Service acquisition drives 

up land prices, a 2010 UNL (University of Nebraska, 

Lincoln) survey reported that agricultural land values in the Rainwater Basin region increased an average of 2.6 percent annually between 2005 and 2010 

(Johnson et al. 2010). During those same five years, 

only 513 acres were acquired in fee title by the Service. In 2009, 74 percent of agricultural lands sold in 

the Rainwater Basin region were purchased by active 

farmers, 21 percent were purchased by nonfarming 

Nebraska residents, and 5 percent were purchased 

by nonfarming out-of-state buyers. 
Chapter 4 — Environmental Consequences 23

UNL’s survey asked 150 land-market observers to 

rank the importance of 16 factors in determining land 

prices. The top three factors were purchasing for farm 

expansion, a limited amount of land offered for sale, 

and the financial health of current owners. Property 

tax levels were ranked 15th out of 16. 

In 2009, 68 percent of land purchases in the Rainwater Basin area were cash purchases and 27 percent 

involved a mortgage; 5 percent of ownership changes 

involved other types of transactions (e.g., gift, inheritance, etc.). During the last decade, the average rate 

of return on assets of agricultural land in the Rainwater Basin region dropped from 5.5 to 4.9 percent. 

INCREASING PROPERTY TAXES

Tax increases are a very contentious issue across the 

State, including in the Rainwater Basin. While land 

brought into Federal ownership is no longer on the 

tax roll, it does not result in an increase in personal 

property taxes paid to the counties. 

For counties with low populations and no commercial hub, agricultural lands represent well over 

half of the county’s total assessed value (Johnson et 

al. 2006). When county costs continue to go up, populations go down, and no new industries are being created, agricultural land claims a higher percentage of 

the county’s total assessed value, shifting the burden 

of financing the county to the shoulders of farmers. 

A contrast that demonstrates this concept is that 57 

percent of the total assessed value in Clay County is 

agricultural land, but it is only 22 percent in adjoining Adams County.

The Refuge Revenue Sharing Act provides for 

payments to counties by the Service in lieu of taxes. 

Revenues for these payments are derived from the 

sale of products from refuges, including animals, timber, and minerals, or from leases and other privileges. 

The revenue is deposited in a special Treasury account 

to be dispersed to counties containing refuge properties. Payment is calculated three different ways, with 

the amount due being the highest of the three methods. The three methods are: 0.75 percent of the appraised property value, 25 percent of the net receipts 

produced on the property, or $0.75 per acre. If the 

funds in the special Treasury account fall short of 100 

percent payment, each county receives payment at a 

lower percentage. In 2009, Refuge revenue–sharing 

payment to Rainwater Basin counties averaged only 

32.3 percent ($90,983) of full payment. 

SOCIAL BENEFITS

Although Service lands do not provide the same property tax revenue to the counties that the land would 

generate in private ownership, there are goods and services produced by these lands that benefit the general 

public. Some benefit the local community directly in 

terms of flood control, groundwater recharge, increased 

water quality, and sediment or nutrient entrapment. 

Recreation, aesthetics, and health and production of 

wildlife may serve the local community as well as a 

much larger society. Other benefits include reduced 

need for water and sewer services and increased law 

enforcement in the local area, thereby reducing costs 

to local communities. 

There is no way to assign dollar values to these 

public benefits. The social and environmental benefits 

provided by the wetlands have very little economic 

value to an individual buyer; the assessed value reflects 

the land’s value for agricultural production. In addition, each wetland provides a specific level of benefits 

depending on its unique characteristics, location in the 

watershed, and proximity to larger communities. For 

example, WPAs located in the more populated eastern 

portion of the Rainwater Basin receive a much higher 

use than those in the western portion.

Studies exist, however, that suggest some of the 

value wetlands provide to the public. In 1978, the Little 

Blue Natural Resources District hired an engineering 

firm to provide a cost-benefit analysis of a watershed 

plan in Clay County. The analysis reported that a 650-

acre impoundment would have an estimated annual 

benefit value of $97.37 per acre. This value was based 

on only three benefits: $52.75 per acre for groundwater 

recharge, $41.14 per acre for flood control, and $3.46 

per acre for recreation. The $97.37 in 1978 is equivalent to approximately $320 in today’s economy. The 

estimate did not include the value of other services 

provided, such as capturing and transforming agricultural runoff or sustaining migratory bird populations. 

A limited amount of agricultural benefit is provided 

by WPAs. In 2009, approximately 12,600 animal-unit 

months of grazing were provided. An additional 1,150 

acres were hayed. 

Publicly owned wetlands within the Rainwater 

Basin are an important factor in bringing hunters and 

birdwatchers to the region. The 2006 National Survey 

of Fishing, Hunting, and Wildlife-Associated Recreation reports that the average hunter in Nebraska 

spends about $25 per day on trip expenses (food, 

lodging, and fuel). For birdwatchers, that number is 

$31.50 per day. The Service estimates that there are 

approximately 80,000 visitor-days within basin WPAs 

each year. Using the $25 per visitor-day figure, that 

number of visitor-days brings $2 million of commerce 

to the region. NGPC estimates that upland game and 

waterfowl hunting provides $2,374,520 of economic activity to the Rainwater Basin (Mark Vrtiska, biologist, 

NGPC; personal communication; 2011). 

These figures demonstrate that the value of benefits provided by WPAs is significant. 
24 Draft EA, Rainwater Basin Wetland Management District Expansion

LANDOWNERSHIP AND LAND USE—

ALTERNATIVE A (NO ACTION)

Under alternative A, many of the wetlands targeted 

for acquisition under this proposal would remain in 

private ownership and on the county tax rolls. An unknown number of them would be converted to cropland 

during drier conditions, but there could be significant 

variations in production across wet and dry years. 

LANDOWNERSHIP AND LAND USE—

ALTERNATIVE B (PROPOSED ACTION)

Under alternative B, 14,177 additional acres of land 

(0.36 percent of the Rainwater Basin region) would 

be permanently protected. The adjoining upland and 

drained portions of wetlands would be converted from 

cropland back to grassland and wetlands. Agricultural 

income from the 5,000 acres of easements would be 

derived from livestock grazing and haying. 

The 9,177 acres purchased in fee title would be 

taken off the county tax rolls with the counties receiving Refuge revenue-sharing funds to help compensate 

for the loss of tax money. 

Lands with a conservation easement would remain on the tax rolls, and the taxes would be paid by 

the landowner. Land use on these properties would 

be limited to the terms of the easement, which would 

allow haying, grazing, and control of public access.

PUBLIC USE—ALTERNATIVE A (NO ACTION)

Under alternative A, public use would remain relatively unchanged. Public access to wetlands targeted 

for acquisition under this proposal would be limited, 

with the property owner deciding the level of access. 

Public pressure on those wetlands currently in public 

ownership would increase, potentially affecting wildlife use of wetland areas.

PUBLIC USE—ALTERNATIVE B (PROPOSED 

ACTION) 

Under alternative B, additional fee-title properties 

would be open to public recreation, including hunting, birdwatching, and environmental education. An 

increase in direct and indirect revenue from recreation would increase. Public pressure on and wildlife 

disturbance to individual wetlands would lessen as 

more areas would be available for use. 

Properties with conservation easements would 

remain in private ownership. Access to the property 

would be at the discretion of the landowner since the 

easement would not include public use.

VALUE OF THE RAINWATER BASIN ECOSYSTEM—

ALTERNATIVE A (NO ACTION)

Under alternative A, the level of wetland protection 

would remain relatively unchanged. Wetlands with 

split ownership between the Service and private 

landowners would continue to have limited benefits, 

especially for waterfowl. Over time the number of 

wetlands regionwide would be expected to continue 

to decline both in numbers and functionality.

VALUE OF THE RAINWATER BASIN ECOSYSTEM—

ALTERNATIVE B (PROPOSED ACTION)

Alternative B would not completely restore the Rainwater Basin ecosystem, but it would help to reduce 

the threat of further losses. Nearly 90 percent of the 

region’s wetlands would remain lost. Wetlands that 

are permanently protected would help ensure that 

the region continues to play a critical role in the migration of millions of ducks, geese, shorebirds, and 

other birds. The wetland values of the acquired areas 

would continue to provide better water quality, quality of life, and wildlife habitat for many generations. 

Unavoidable Adverse 

Impacts

Any adverse effects that may be unavoidable while 

carrying out alternatives A and B are described below.

ALTERNATIVE A (NO ACTION)

Under alternative A, the adverse impact of habitat 

degradation and fragmentation would be expected to 

be more widespread and prevalent. 

ALTERNATIVE B (PROPOSED ACTION)

Under alternative B, the expansion of land acquisition 

would cause a direct decline in taxes paid to counties. 

Irreversible and Irretrievable 

Commitments of Resources

Any commitments of resources that may be irreversible or irretrievable as a result of carrying out alternatives A and B are described as follows.

ALTERNATIVE A (NO ACTION)

Under alternative A, there would be no additional 

commitment of resources by the Service if no action 

is taken. Wetlands altered to cropland, especially irrigated cropland, are irretrievable and contribute to 

the overall loss of migration habitat.

ALTERNATIVE B (PROPOSED ACTION)

Under alternative B, there would be an irretrievable 

and irreversible annual commitment of funds to protect and manage these lands. The potential for the 

property to be used for crop production would be gone.
Chapter 4 — Environmental Consequences 25

Short-Term Use versus LongTerm Productivity

This section describes the effects of short-term use 

versus long-term productivity of alternatives A and B.

ALTERNATIVE A (NO ACTION)

Under alternative A, landowners would be able to 

convert wetlands to cropland, which would boost agricultural production but would also have a long-term 

negative effect on migratory bird habitat. 

ALTERNATIVE B (PROPOSED ACTION)

Under alternative B, land acquisition would perpetually 

preserve wetlands and adjoining grasslands. The loss 

of direct tax revenue to the affected counties would 

have a long-term impact. 

Cumulative Impacts

Cumulative impacts are defined by NEPA as the impacts on the environment that result from the incremental impact of the action when added to the other 

past, present, and reasonably foreseeable future 

actions regardless of what agency (Federal or nonFederal) or person undertakes such other actions (40 

CFR § 1508.7)

PAST ACTIONS

Past land acquisition by the Service or the NGPC has 

included 31,823 acres of wetland and grassland. The 

Wetland Reserve Program administered by NRCS 

has added 7,077 acres in conservation easements. 

The total of these acres represents approximately 

1.0 percent of the Rainwater Basin. These lands are 

managed primarily for the social benefits wetlands 

provide, particularly for wetland and grassland birds. 

PRESENT ACTIONS

The Service’s proposed action to expand land acquisition authority to 38,177 acres would add an additional 

14,177 acres to the National Refuge System, 5,000 of 

which would be conservation easements. Land acquisition by NGPC is limited and is driven by available 

funds and willing sellers. The Wetland Reserve Program continues to be an active program. The Wetland 

Reserve Program areas, however, are not open for 

public use. Ducks Unlimited is actively seeking willing sellers and is obtaining both fee-title and easement 

properties. Its acquisitions are directed toward purchasing property, restoring the wetland and upland, 

protecting it with a conservation easement, and then 

selling the property. Present actions by conservation 

groups support the goals of the Service and the Rainwater Basin Joint Venture.

REASONABLY FORESEEABLE FUTURE ACTIONS

Reasonably foreseeable actions are actions and activities that are independent of the proposed expansion 

addressed in this document. They are anticipated to 

occur regardless of which alternative is selected. Increased production of ethanol and demand for corn and 

soybeans are expected to encourage increased acreage of, and production from, farmland. A significant 

portion of that increased acreage can be expected to 

come from wetland conversion. Future wetland conservation will be done primarily by the U.S. Department of Agriculture and nongovernmental conservation organizations. 

Wind energy development is currently being considered for the region. The potential for this development is uncertain at this time. 

DEVELOPMENT—ALTERNATIVE A (NO ACTION)

Much of the development within the Rainwater Basin 

has been and would continue to be related to agriculture. Since 90 percent of the historic wetlands have 

already been converted or lost, the number of wetlands 

that would be affected by additional development in 

the future would be small, but the development would 

significantly affect the wetlands that remain. For example, over 2,300 acres of grassland were converted 

to cropland in just four counties within the Rainwater 

Basin in 2009. The long-term, cumulative effect would 

likely result in the continuation, and possible acceleration, of the decline in waterfowl, shorebird, and other 

migratory bird populations. 

DEVELOPMENT—ALTERNATIVE B (PROPOSED 

ACTION)

The proposed action would restore and protect an additional 14,177 acres of wetland and grassland areas 

for the benefit of the public and wildlife. 

CONSERVATION EFFORTS—ALTERNATIVE A (NO 

ACTION)

Under alternative A, current Service programs such 

as Partners for Fish and Wildlife would continue 

within the Rainwater Basin region. The Service would 

continue to work cooperatively with landowners to 

voluntarily improve habitat on private land through 

various conservation means such as prescribed fire, 

range management systems, or native plantings. Those 

landowners wishing to sell off unproductive wetland 

acres would have fewer options for selling.

CONSERVATION EFFORTS—ALTERNATIVE B 

(PROPOSED ACTION)

Alternative B would allow for the protection of an 

additional 14,177 acres of wetland and grassland 
26 Draft EA, Rainwater Basin Wetland Management District Expansion

habitats. These acres would be added to the 23,855 

acres currently owned and managed by the Service. 

The action would have a long-term positive impact on 

wildlife habitat, significantly add to the management 

capability for existing wetlands, and help the Service 

meet the goals in the North American Waterfowl Plan. 
Chapter 5 — Coordination and 

Environmental Review

Agency Coordination

The Service has discussed the proposal to expand land 

acquisition in the Rainwater Basin with landowners; 

conservation organizations; other Federal agencies; 

tribal, State, and county governments; and other interested groups and individuals. 

The Service held two public meetings, in Holdrege 

and Clay Center, Nebraska in January 2011 to provide 

information and discuss the proposal with landowners 

and other interested citizens. Information on the proposal has been made available to county commissioners 

in each of the 13 counties included in the project area.

At the Federal level, information was provided 

to the Congressional delegation, as well as to representatives from the U.S. Department of Agriculture 

(NRCS). At the State level, information was provided 

to Governor Heineman’s staff and Nebraska’s State 

senators. Information was also provided to tribes 

within the State. 

Nongovernmental conservation groups are vital to 

the success of the proposed project. Service staff has 

coordinated with partner organizations such as The 

Nature Conservancy, Natural Resource Districts, and 

Ducks Unlimited. 

Contaminants and Hazardous 

Materials

Surveys for contaminants would be conducted before 

any land interests are acquired. Fieldwork for the 

preacquisition surveys would be conducted on a tractby-tract basis. Any suspected problems or contaminants requiring additional surveys would be referred 

to a contaminants specialist located in the Service’s 

Ecological Services office in Grand Island, Nebraska.

National Environmental 

Policy Act

As a Federal agency, the Service must comply with 

provisions of NEPA. An environmental assessment 

is required under the act to evaluate reasonable alternatives that will meet stated objectives and to assess the possible impacts to the human environment. 

The environmental assessment serves as the basis for 

determining whether implementation of the proposed 

action would constitute a major Federal action significantly affecting the quality of the human environment 

and the need for an environmental impact statement. 

The analysis for, and development of, this environmental assessment facilitated the involvement of 

government agencies and the public in the decisionmaking process.

Strategic Habitat 

Conservation and Landscape 

Conservation Cooperatives 

SHC (strategic habitat conservation) is a means of applying adaptive management across large landscapes. 

Landscape conservation cooperatives will facilitate 

strategic habitat conservation (USFWS 2008).

STRATEGIC HABITAT CONSERVATION

The Rainwater Basin expansion proposal would apply 

the strategic habitat conservation framework outlined 

in the National Ecological Assessment Team report 

(National Ecological Assessment Team 2006). SHC 

involves an ongoing cycle of biological planning, conservation design, conservation delivery, outcome-based 

monitoring, and assumption-based research (figure 

6). It is the process by which the Service continues to 

develop and apply science focused on improving the 

ability to apply conservation delivery actions that result in landscapes capable of supporting populations of 

priority species at desired levels. Additionally, SHC 

provides the framework by which the Service develops 

and applies science to inform and continually improve 

conservation delivery by addressing landscape-level 

population-limiting factors in an adaptive manner.

The Service’s Region 6 Refuges Program has established a GIS office in Grand Island that works 

closely with the Rainwater Basin Joint Venture and 

the Rainwater Basin Wetland Management District 

to provide support for the biological planning, conservation design, conservation delivery, and monitoring/
28 Draft EA, Rainwater Basin Wetland Management District Expansion

research elements of SHC necessary to implement the 

proposed action. This environmental assessment addresses the four key SHC elements: planning, design, 

delivery, and monitoring and research.

Figure 6 . The elements of strategic habitat 

conservation

BIOLOGICAL PLANNING

Priority resources were described in earlier chapters 

of this document. Biological planning requires the identification of priority species, development of population objectives, and identification of landscape-level 

limiting factors that keep the populations of priority 

species below desired levels. Initial biological planning 

was done using dabbling ducks and a subset of goose 

populations as focal species. This approach was based 

on the assumption that protection and management of 

wetlands in a manner that meets the biological needs 

of the focal species will also adequately meet the needs 

of other wetland species. 

Conceptual and quantitative models have been 

developed to identify specific wetlands and wetland 

complexes. Priority species would continually be defined and updated throughout the implementation of 

the proposed action, and additional landscape models would be developed for priority species. Biological planning will continue into the future, engaging 

partners in the population objectives and developing 

biological models that will be directly linked to conservation delivery actions.

CONSERVATION DESIGN

Land acquisition is most effectively completed using 

biologically driven, spatially explicit models. During the past decade, the Service, in cooperation with 

the Rainwater Basin Joint Venture, has used GIS to 

extensively map the Rainwater Basin region. Modeling has identified and ranked each hydric soils area, 

including both drained and existing wetlands. Key 

spatial and biological characteristics of each area were 

scored to determine which wetlands are cost effective 

to acquire and restore. The analysis considered the 

impacts of geographic features such as the proximity 

of other wetlands, roads, and power lines to individual 

wetlands. Color-coded maps reflect an individual wetland’s priority for fee-title acquisition, easement, and 

other types of conservation programs. 

The information obtained from the model was also 

used in conjunction with the management history of 

existing WPAs to identify where roundout acquisition is most needed.

CONSERVATION DELIVERY

The Rainwater Basin Wetland Management District 

has worked with neighboring landowners, conservation organizations, and government agencies for almost five decades to preserve and enhance wetlands 

throughout the region. Beginning in the early 1990s, 

Partners for Fish and Wildlife biologists have worked 

with the same partners to bring conservation programs to wetland owners regardless of their proximity to existing Service properties. Application of the 

SHC framework will build on existing partnerships 

and support the development of new partnerships for 

delivering conservation throughout the ecoregion. 

It is recognized that the past practice of opportunistic acquisition will not result in the best use of 

conservation dollars. The function of some wetlands 

can best be used or enhanced by short-term conservation programs. Computer modeling of waterfowl 

energetic needs and wetland priority mapping allows 

for greater flexibility, increased responsiveness, and 

improved efficiency in meeting Service and partner 

conservation delivery needs.

Conservation design will continue to involve the 

development of spatially explicit decision support tools 

for targeting conservation delivery actions. Research 

and monitoring will help update the modeling parameters used to develop conservation priorities.

MONITORING AND RESEARCH

The success of the proposed action would depend 

on its ability to adapt to new and better information 

gathered through research and monitoring. Currently, 

monitoring and research are being done on a variety 

of subjects to provide for better decision making in 

the future. At the end of each growing season, wetlands are examined to assess the response of plant 

communities and seed production to different management actions. This information is being used to 

develop a strategic decision-making matrix to guide 

future management. Bird use associated with wetland juxtaposition is being analyzed to confirm if our 
29

current understanding of wetland complexes aligns 

with what occurs in the field. A study of the relationship between groundwater recharge and wetland characteristics was recently completed. Research related 

to grazing intensity and its impact on the control of 

reed canarygrass is beginning its final year. Information from these studies and future work on landscape 

ecology will be incorporated into the SHC process to 

further refine biological planning.

LANDSCAPE CONSERVATION COOPERATIVES

The Service will use LCCs (Landscape Conservation 

Cooperatives) as a means of implementing strategic 

habitat conservation. LCCs will be formal scientific 

and management partnerships between the Service, 

the U.S. Geological Survey, other Federal agencies, 

States, tribes, nongovernmental organizations, universities, and others to increase the capacity for applied 

conservation science in support of fish and wildlife 

management in specific landscapes (Secretarial Order Number 3289). The tools developed by the LCCs 

will allow Service offices, and our many partners, to 

implement on-the-ground actions in the most effective 

locations to meet conservation goals. 

The Rainwater Basin Expansion Project is part of 

the Great Plains LCC, which was recently developed. 

The project meets the criteria of the LCC initiative: 

cooperation among private landowners and other 

agencies (Federal, State, local, and nongovernmental 

organizations). In addition to fostering partnerships, 

the LCCs provide science support to managers. 

The Secretary of the Interior recently outlined the 

importance of LCCs as a response to climate change 

(USFWS 2009). LCCs reach across broad landscapes, 

involve many partners, and function at a scale necessary to address wildlife adaptation in response to climate change. The Rainwater Basin Expansion Project 

would contribute to the wetland protection projects of 

Ducks Unlimited, NGPC, Natural Resource Districts, 

and the U.S. Department of Agriculture. 

These cooperatives will continue to grow as a 

means of delivering strategic habitat conservation. The 

Service and the U.S. Geological Survey have signed 

a memorandum of understanding to strengthen the 

science–management relationship in landscape-level 

conservation. This further commitment to strategic 

habitat conservation improves the basis for the type 

of landscape conservation being proposed.

Rainwater Basin Flora List 

for Waterfowl Production 

Areas, Version 2 .0

The U.S. Fish and Wildlife Service maintains a list of 

plant species (422) that occur in wetlands (http://www.

fws.gov/nwi/bha/list88.html). The following list of plants 

for the Rainwater Basin Waterfowl Production Areas 

was generated using the Region 5 (1,523 plant species) 

map from this Web site. The USDA Plants Web site 

(http://plants.usda.gov) listed 9,485 plant species for 

Nebraska. Both the USDA Plants Web site and the 

NatureServe Explorer1 Web site were used to verify 

scientific names, common names, and habits for those 

species not listed on the FWS Web site.

SCIENTIFIC NAME

The genus and species applied to the taxon were derived from Kaul et al. (2006) and NatureServe Explorer (2010).

CoMMoN NAME

A popular name applied to the species. Common name 

selection generally follows common names from North 

American Plants2 (Kartesz and Thieret 1991), but some 

common names follow the current common name list 

maintained by the Natural Resources Conservation 

Service and/or NatureServe.

NATIoNAL RANgE INDICAToRS

The national indicators reflect the range of estimated 

probabilities (expressed as a frequency of occurrence) 

of a species occurring in wetlands versus nonwetlands 

across the entire distribution of the species. A frequency 

of, for example, 67 percent–99 percent (facultative 

wetland) means that 67 percent–99 percent of sample 

plots containing the species randomly selected across 

the range of the species would be wetland. A question 

mark (?) following an indicator denotes a tentative 

assignment based on the botanical literature and not 

confirmed by regional review. When two indicators 

are given, they reflect the range from the lowest to 

the highest frequency of occurrence in wetlands across 

1 http://www.natureserve.org/explorer/

2 http://www.unl.edu/agnicpls/gpcn/about.html

the regions in which the species is found. A positive 

(+) or negative (-) sign was used with the facultative 

indicator categories to more specifically define the regional frequency of occurrence in wetlands. The positive sign indicates a frequency toward the higher end 

of the category (more frequently found in wetlands), 

and a negative sign indicates a frequency toward the 

lower end of the category (less frequently found in 

wetlands).

NATIoNAL WETLAND INDICAToR (INDICAToR 

CATEgoRIES):

■■ Obligate Wetland (OBL). These species almost always occur under natural conditions in wetlands 

(estimated probability >99 percent).

■■ Facultative Wetland (FACW). Usually occur in 

wetlands (estimated probability 67 percent–99 

percent), but occasionally found in nonwetlands.

■■ Facultative (FAC). Equally likely to occur in wetlands or nonwetlands (estimated probability 34 

percent–66 percent).

■■ Facultative Upland (FACU). Usually occur in 

nonwetlands (estimated probability 67 percent–99 

percent), but occasionally found in wetlands (estimated probability 1 percent–33 percent).

■■ Obligate Upland (UPL). Occur in wetlands in another region, but occur almost always (estimated 

probability >99 percent) under natural conditions 

in nonwetlands in the region specified. If a species 

does not occur in wetlands in any region, it is not 

on the National List.

The wetland indicator categories should not be equated 

to degrees of wetness. Many obligate wetland species 

occur in permanently or semipermanently flooded wetlands, but a number of obligates also occur and some 

are restricted to wetlands that are only temporarily 

or seasonally flooded. The facultative upland species 

include a diverse collection of plants that range from 

weedy species adapted to exist in a number of environmentally stressful or disturbed sites (including 

wetlands) to species for which a portion of the gene 

pool (an ecotype) always occurs in wetlands. Both the 

weedy and ecotype representatives of the facultative 

upland category occur in seasonally and semipermanently flooded wetlands.

REgIoN 5 WETLAND INDICAToR (REgIoNAL 

INDICAToR FoR 5-CENTRAL PLAINS NE, kS, AND 

Co [EASTERN])

The wetland Indicator status estimates the probability 

(likelihood) of a species occurring in wetlands rather 

than nonwetland areas within this region. Regional 

indicators reflect the unanimous agreement of the Regional Interagency Review Panel. If a regional panel 

was not able to reach a unanimous decision on a species, NA (no agreement) was recorded on the regional 

indicator field. An NI (no indicator) was recorded for 

those species for which insufficient information was 

available to determine an indicator status. A nonoccurrence (NO) designation indicates that the species 

does not occur in that region. An asterisk (*) following 

a regional indicator identifies tentative assignments 

based on limited information from which to determine 

the indicator status. 

HABIT

The plant characteristics and life forms assigned to 

each species in the National List of Scientific Plant 

Names3 (1982) and by the Natural Resources Conservation Service. Family names are listed alphabetically 

under specific life forms restricted to these families. 

The HABIT symbols are combined to describe the life 

form of the species (e.g., ANG means annual native 

grass, IT means introduced tree).

Taxonomic List of Birds That Have occurred in the Rainwater Basin

(Order follows the A.O.U. Check-list of North American Birds, 7th ed. Sept.1998)

Birds of the Rainwater Basin Wetland Management District 

After each species name, one space is entered, then the seasonal abundance codes. The letter "m" was used to indicate 

that the species is not present during a particular season. For example, “American coot acar” (abundant in spring, common in summer, abundant in fall, rare in winter) or "California gull omom" (occasional in spring, not present in summer 

or winter, occasional fall). 

Nesting species documented in WPAs (Waterfowl Production Areas) are marked with an asterisk (*) in front of the species name. Species accounts may indicate presence during the nesting season, but may not be marked as nesting. For 

example, frequent nesters in the area such as northern rough-winged swallow are not marked as nesters because WPAs 

do not provide preferred nesting habitat. For the most part, cavity nesters are excluded (the red-bellied woodpecker prefers mature, natural woodlands) due to the absence of mature or dying trees that typically provide cavities. The Rainwater Basin WPAs are managed as grassland-playa lake ecosystems. Non-native trees and shrubs have been removed on 

most WPAs. Due to remaining shelter belts on WPAs, a few woodland nesters are marked as nesting if they are known 

to use shelter belts. 

Seasonal Abundance Definitions 

Seasons are listed below. Seasonal abundance codes for some species such as shorebirds may be misleading because their 

fall migration starts in July or August (summer season). For example: "pectoral sandpiper cccm" (common in spring, common in summer due to peak migration occurring from mid-August through fall, not present in winter). 

A. Seasons: B. Seasonal Abundance: 

Spring (March-May) a = abundant: occurring in large numbers 

Summer (June-August) c = common: certain to be seen in suitable habitat 

Fall (September-November) u = uncommon: present, but not certain to be seen 

Winter (December-February) o = occasional: seen only a few times during the season 

 r = rare: seen at intervals of 2-5 years 

 h = hypothetical: within normal range, but never documented or has 

been extirpated 

 x = outside normal range, but has been documented

Draft Land Protection Plan

This Land Protection Plan provides a general description of the operations and management of the Rainwater 

Basin Expansion Project (Rainwater Basin Wetland 

Management District Expansion Project, as outlined 

in the proposed action described in the Rainwater Basin Wetland Management District Expansion Project 

Environmental Assessment. The Service (U.S. Fish 

and Wildlife Service) developed this Land Protection 

Plan to provide local landowners, governmental agencies, and the interested public with a general understanding of the anticipated management approaches 

for the proposed acquisition program. The purpose 

of the Land Protection Plan is to present a broad 

overview of the Service’s proposed management approach to wildlife and associated habitats, public uses, 

interagency coordination, public outreach, and other 

operational needs.

Introduction and Project 

Description

The Rainwater Basin Expansion Project would be 

implemented in the main portion of the Rainwater 

Basin region of south central Nebraska. Although the 

Rainwater Basin includes all or portions of 21 counties, the project would be restricted to the 13 counties 

that currently make up the Rainwater Basin Wetland 

Management District: Adams, Clay, Fillmore, Franklin, Gosper, Hall, Hamilton, Phelps, Polk, Kearney, 

Saline, Seward, and York (figure 1).

The region is characterized by low, rolling topography with loess soils and contains a high density of 

shallow wetlands that are an internationally known 

stopover for migratory birds. Settlement of the region 

resulted in the conversion, primarily to cropland, of 

about 84 percent of the historic wetlands. The remaining wetlands are becoming increasingly important to 

the central flyway. Birds from the gulf coast states and 

Mexico funnel through this region before spreading 

out across the Prairie Pothole Region and areas further north. While here, ducks, geese, and shorebirds 

use the wetlands for food and resting. Body fat gained 

while in the Rainwater Basin is needed for successful 

production on their nesting grounds. 

The Service intends to expand its acquisition program from its current limit of 24,000 acres to 38,177 

acres. The Service will purchase 9,177 acres in feetitle and the remaining 5,000 acres in conservation 

easements. The specific locations of the acquisitions 

are not known nor can they be determined. The lands 

that will be acquired will be based on willing sellers 

and identified wetland characteristics. The identified 

wetland characteristics are those that have the most 

influence on waterfowl use.

The purposes of the Rainwater Basin Expansion 

Project are to:

■ Preserve the landscape-scale ecological integrity of 

the Rainwater Basin by maintaining and enhancing the hydrology, flora, and fauna of wetlands. 

■ Support the recovery and protection of threatened 

and endangered species and reduce the likelihood of 

future listings under the Endangered Species Act.

■ Provide a buffer against climate change by providing 

migrational habitat for millions of migrating birds.

■ Increase the amount of natural foods available to 

support healthy productive birds on their northern nesting areas.

Threats to and Status of the 

Resources

A spring 2004 assessment of available wetland habitat 

showed that only 16 percent of the historical wetlands 

had some wetland function. The rest have been lost to 

development. Today, only 8.5 percent (18,067 acres) of 

the historic wetland acres are in public ownership. Public wetlands are represented by 90 distinct properties, 

containing all or portions of 168 wetlands or 1.5 percent of the 11,000 historical wetlands (USFWS, Grand 

Island GIS Shop, unpublished). These few wetlands 

provide about 45 percent of the waterfowl habitat in 

the region. Increasing commodity prices are causing 

higher land prices and more development, threatening the remaining unprotected wetlands.

The conversion of wetlands and grassland has 

caused birds to concentrate in fewer areas, increasing the risk of disease outbreaks and competition for 

natural foods. Waste grain has replaced much of the 

natural foods in waterfowl diets. Although corn meets 

the caloric requirements, it is deficient in many of the 
64 Draft LPP, Rainwater Basin Wetland Management District Expansion

nutrients found in natural foods (Baldassare and Bolen 

1994, Krapu et al. 2004). 

Proposed Action

The Service would increase its land acquisition goal 

from 24,000 to 38,177 acres within the Rainwater 

Basin Wetland Management District. All the lands 

will be acquired from willing sellers, with acquisition 

occurring over as many years as necessary to reach 

the new goal. 

Property would be purchased by one of two methods: fee-title and easement. Fee-title acquisition 

would total 9,177 acres and would target two types of 

wetlands: those currently sharing partial ownership 

by the Service, and larger wetlands located within a 

complex of smaller wetlands. 

Conservation easements would be purchased on 

5,000 acres. Approximately 2,500 acres would be wetlands, with the remaining 2,500 being surrounding upland buffer. Easements will be purchased from willing 

sellers and will be restricted to those wetlands located 

near State and Service-owned wetlands.

Purchase of both fee-title and easements would 

be done strategically using GIS technology to identify those wetlands having the highest potential for 

waterfowl habitat. Wetlands would be prioritized by 

rating wetland and landscape characteristics that are 

critical to waterfowl. 

Protection Alternatives

Protection alternatives are limited to no action, acquisition by others, or acquisition by the Service.

NO ACTION

The consequences of the No-Action Alternative were 

considered unacceptable and led to the selection of the 

proposed action to expand land acquisition to 38,177 

acres. Under this alternative, the Service would continue acquiring wetlands until it reaches its current 

authorization of 24,000 acres. After the authorization level has been reached, any additional acres in 

the Rainwater Basin that would come under Service 

ownership would come from donations or gifts from 

landowners, conservation organizations, and other 

government agencies. 

Management of Service lands would continue as 

described in the 2007 Rainwater Basin Comprehensive Conservation Plan. WPAs (waterfowl production 

areas) with portions of the wetland in private ownership would not reach their full potential. Prescribed 

burning, pumping, and grazing would be more limited 

because of split ownership. Refuge revenue-sharing 

payments would continue to be made to counties with 

Service lands. 

Many of the privately owned wetlands vulnerable to drainage or other destruction would be lost. 

The burden to protect wetlands without compensation would lay more heavily on private landowners. 

Future wetland protection would rely primarily on 

the Wetland Reserve Program and conservation organizations such as Ducks Unlimited. Although their 

contributions are significant, they are not expected 

to be enough to meet waterfowl needs. Conservation 

work by a wider spectrum of conservation partners 

would be needed. 

EXPANSION OF LAND ACQUISITION (PROPOSED 

ACTION)

Strategic acquisition of fee-title and conservation 

easements is the best strategy for ensuring that key 

wetlands reach their full potential. Under the proposed 

action, the Service would increase its acquisition goal 

from 24,000 acres to 38,177 acres within the Rainwater 

Basin Wetland Management District. Lands would be 

acquired from willing sellers only, and the focus would 

be on wetlands. Wetlands having characteristics that 

are biologically important to migratory birds would be 

targeted. Those characteristics include the potential 

hydrology and location of the wetland in relation to 

other important wetlands. Factors such as the presence of roads and power lines would also be considered 

when wetlands are prioritized. 

Priority Areas

A rating system that considers the various characteristics important to migratory birds has been developed by the Rainwater Basin Joint Venture and area 

biologists. Using GIS technology, a priority map was 

created that identifies individual wetlands as well as 

complexes of wetlands that provide the most benefit 

to birds. 

Overall, the proposed action would focus on acquiring fee-title in two types of wetlands. The highest 

priority would be to acquire portions of wetlands that 

adjoin existing WPAs, which would allow for better 

management of the entire wetland. Management practices such as prescribed burning, grazing, and water 

delivery are more effective when the entire wetland 

can be managed. The second type of wetlands that 

would be considered for acquisition would be larger 

wetlands located within a complex of smaller wetlands. 

Waterfowl prefer using wetlands within a complex of 

wetlands. A complex provides different wetlands for 

different needs, such as feeding, loafing, and roosting. 

Easement acquisition will target smaller wetlands 

close to a larger, publicly owned wetland. This strategy 

would allow the numerous small wetlands to remain in 

private ownership while still protecting the integrity 

of the wetland complex. Easements would protect the 
65

wetlands from future alteration and keep the adjoining upland in grassland. The landowner would retain 

access, grazing, and haying rights. 

Management

Acquired lands would be managed by the Rainwater 

Basin Wetland Management District, as described in 

2007 Comprehensive Conservation Plan. Easement 

monitoring would include periodic review of land status 

through correspondence and meetings with landowners or managers to ensure that the stipulations of the 

easement are being met. 

Payment in lieu of taxes from the Refuge Revenue Sharing Act will be paid to counties for lands 

in fee-title ownership by the Service. Taxes on lands 

containing a conservation easement will continue to 

be paid by the landowner. 

Acquisition Alternatives

The Service proposes to acquire conservation easements principally by using funds appropriated under 

the LWCF (Land and Water Conservation Act), which 

derives funds from royalties paid for offshore oil and 

gas leasing. Such funds are intended for the protection 

of recreational and natural resource lands. Funding 

is subject to annual appropriations by Congress for 

specific acquisition projects. 

Monies from other sources may also be used within 

the project area. Funding for management of acquired 

properties will come from Congress as appropriated 

to the National Refuge System.

Coordination

The Service has discussed the proposal to expand land 

acquisition in the Rainwater Basin with landowners; 

conservation organizations; other Federal agencies; 

tribal, State, and county governments; and other interested groups and individuals. Approximately 170 

fact sheets were mailed out, and project information 

was also made available at the Wetland Management 

District and regional planning Web sites.

The Service held two public meetings to provide 

information and discuss the proposal with landowners 

and other interested citizens. Information on the proposal has been made available to county commissioners 

in each of the 13 counties included in the project area.

At the Federal level, information was provided to 

the Congressional delegation as well as to representatives from the U.S. Department of Agriculture (Natural 

Resources Conservation Service). At the State level, 

information was provided to Governor Heineman’s 

staff and Nebraska’s senators. Information was also 

provided to tribes within the State. 

Nongovernmental conservation groups are vital to 

the success of the proposed action. The Service has 

coordinated with partner organizations such as The 

Nature Conservancy, Natural Resource Districts, and 

Ducks Unlimited.

Socio-cultural 

Considerations

Rainwater Basin is recognized as among the most 

productive cropland in Nebraska. The fertile soils, 

accompanied by irrigation, allow for the high annual 

yields of corn and soybeans. For the numerous small, 

rural towns, agriculture is the basis of their existence. 

Larger commercial hubs such as Hastings and Grand 

Island have a broader economic base, including manufacturing and service industries. 

Counties containing only small towns rely heavily 

on real estate taxes on agricultural land to support 

their infrastructure and services. As land is converted 

from low-production to high-production agriculture 

(such as irrigated farmland), tax assessment goes up, 

which in effect slightly lessens the tax burden on all 

other landowners. 

Even when it is not economically prudent to farm 

a piece of property, the culture encourages attempts 

to farm it. It is common to see wetlands or wet soils 

consistently farmed with little or no harvest occurring. 

Wetland restoration and preservation is often seen 

as “counter-culture” within the rural communities. 

Wetlands that are permanently protected are seen 

as potential farming land that is lost for production 

and tax revenue. These areas are often referred to as 

waste ground. The three common concerns associated 

with wetland protection—and expressed within the 

rural communities—are loss of tax revenue, declining 

rural populations, and higher land prices. 

In contrast, conservation organizations see a strong 

need to protect the remaining wetlands before they 

too are converted. The result is animosity toward the 

organizations and wetland protection. 

Such animosity has been expressed most in Clay 

County. The county is located within the Rainwater 

Basin’s highest concentration of wetlands, and the 

Service owns more wetland acres in this county than 

any other in the basin. Last year, the County Board 

of Supervisors sent out letters to other counties’ governments throughout the State asking them to support opposition to Service acquisition of lands within 

the State. 

Outside the Rainwater Basin, people are generally supportive of wetland protection and recognize 

Draft Land Protection Plan
66

the basin’s value as a Nebraska natural resource and 

its contribution to bird migrations. 

Summary of Proposed Action

The Service intends to purchase an additional 14,177 

acres of wetlands and associated uplands for the benefit 

of migrating birds, primarily waterfowl and shorebirds. 

Fee-title acquisition will be used to acquire 9,177 acres. 

Easement acquisition will be used to acquire protection rights on the remaining 5,000 acres. Purchases 

will be from willing sellers and will strategically target those wetlands that most benefit migratory birds. 

Fee-title acquisition will be on two types of wetlands, 

those partially in private ownership but part of a WPA, 

and larger wetlands that serve as the core wetland 

in a complex of smaller wetlands. Easements will be 

purchased on biologically significant wetlands that lie 

close to State or Federally owned wetlands.
