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...

We obtained statewide spatially explicit gridded soil survey data for Nebraska from the Soil Survey Geographic (SSURGO) database. The ‘chorizon,’ ‘chtexture,’ ‘chtexturegrp,’ ‘mapunit,’ and ‘mutext’ tables in the Gridded SSURGO database were joined together using the “mukey” attribute field in a geographic information system (GIS). The representative values for slope (rvslope) and slope length (rvslopelenusle), the susceptibility of the soil to water erosion (Kw), and the soil loss tolerance (t_fact) values were obtained from the set of joined tables and were included in the Water Erosion Index calculation. We acquired county-specific rainfall and runoff factor values (R) from the U.S. Department ofAgriculture’s...

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,...

These are vector (polygon) inventories of woodland features that were part of a Rainwater Basin land cover mapping effort. These features were digitized using 2010 USDA National Agricultural Imagery Program (NAIP). These features created in 2011-2012 and were incorporated in to RWBJV Nebraska land covers starting in version 10.
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...
