The Rainwater Basin (RWB) wetland complex in south-central Nebraska provides crucial stopover habitat for over 7 million waterfowl and 500,000 shorebirds every spring. However, only 10% of the original RWB wetlands remain, resulting in less available habitat for wetland-dependent birds. Conservation efforts are being employed to alleviate the loss of RWB wetlands. To aid conservation efforts, we created a vegetation map of all historical RWB wetlands based on 2004 imagery. The shapefile maps the 2004 vegetation communities for all historic wetlands in the Rainwater Basin region of Nebraska, USA. Vegetation communities include cropped areas that rarely pond water, cropped areas that often pond water, bare soil...

Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including...

Historic wetlands based on soils, historic wetland surveys, National Wetland Inventories (NWI) and inventories conducted by the Rainwater Basin Joint Venture.

The Rainwater Basin Joint Venture (RWBJV) used wetland complex models for analysis in their conservation actions. A Historic Wetland Mask (HWM) was used as analysis features for the playa wetlands. The HWM is a GIS layer created by merging all of the playa wetland features identified from four sources: historic soil surveys , National Wetland Inventory, Soil Survey Geographic Database and a 2005 Ducks Unlimited satellite inventory. Using the HWM allows the model to analyze all potential historic wetlands and evaluate their restoration potential as waterfowl habitat. A combination of raster and vector-based spatial analysis was performed on the historic wetland footprints. Factors included in the mask were size,...

This shapefile maps the 2012 vegetation communities for all historic wetlands in the Rainwater Basin region of Nebraska, USA. Vegetation communities include cropped areas that rarely pond water, cropped areas that often pond water, bare soil or mudflat, standing water, moist soil species, wetmeadow species, grasses, reed canarygrass, river bulrush, cattail, and woody species. Communities are based on training data from 2012 field vegetation surveys of over 12,000 points. This map is an update of a RWB vegetation map created in 2004. These data were processed by Ele Nugent, Roger Grosse, and Andy Bishop with the Rainwater Basin Joint Venture (RWBJV), with help from RWBJV Geographic Information Systems Laboratory...

Working with the conservation partnership in the Central Loess Hills BUL, this project was designed to develop the necessary baseline data and species habitat models needed to guide targeted conservation. Development of a conservation portfolio for the Central Loess Hills required five separate, but equally important elements. The elements of this project were: 1) Develop a spatially accurate landcover that delineates key habitats for which at-risk species respond, 2) Analyze landcover to develop meaningful landscape indices that can be used to develop spatially explicit species habitat models, 3) Collect and compile occurrence data for priority species (greater prairie chicken, whooping crane, and waterfowl), 4)...

This ranking criterion was developed to identify those pits that most negatively impact watershed integrity of publically owned and Wetland Reserve Program (WRP) playa wetlands. Currently, the U.S. Fish and Wildlife Service (USFWS) manages 59 Waterfowl Production Areas (WPAs) while the Nebraska Game and Parks Commission oversees 35 Wildlife Management Areas (WMAs). These wetlands flood as a result of precipitation or snow melt. With the transition to pivot irrigation, a large number of irrigation reuse pits have been abandoned over recent years. Although not being used for irrigation, these pits continue to fill with water from precipitation events shortstopping water that could have reached the neighboring...
