The US Prairie Pothole Region (PPR) has experienced some of the highest rates of grassland loss in North America over a time that coincides with dramatic declines in grassland songbird populations yet increasing abundance of most grassland-nesting duck species except for northern pintail. To provide more insight into this contradiction, we propose to capitalize on long-term databases to evaluate how a key population driver nest survival for North American ducks has responded to system changes in the region including landscape and climatic factors. Outcomes of these analyses will contribute to testing primary conservation planning assumptions for the PPJV a vital component of the PPJV Strategic Habitat Conservation...

Using a solutions-oriented, multi-agency collaboration, we propose to pilot a large-scale assessment of an alternative (herding, electric- and virtual-fence) grazing strategy designed to mimic pre-colonial grazing patterns by bison, to ascertain their value for local- and regional-scale assemblages ofsagebrush- and grassland-associated birds in Montana. A fundamental goal of most wildlife-based grazing programs is to foster a mosaic of patches that represent the broadest possible spectrum of habitat types that benefits different sagebrush- and grassland-associated birds in different parts of the landscape (for example, western meadowlarks, vesper sparrows, and thick-billed longspur in open, heavily grazed areas;...

Grassland loss to woody encroachment is widespread and ongoing. Mechanical removal of Eastern Red Cedar (ERC) is the most cost-shared practice to address this threat. Cost-share is provided based on acres with different levels of infestation. Delineation of the different levels of infestation is time consuming butrequired to ensure the appropriate amount of cost-share is provided and contractors are not over/under compensated. The Rangeland Brush Estimation Toolbox(RaBET) is geospatial tool that can accurately automate this process. Unfortunately,wet-meadows and other wetland features cause the tool to overestimate woody cover. This project will provide funds to finish the National Wetlands Inventory (NWI). This...

Maintaining the native prairie lands of the Northern Great Plains (NGP), which provide an important habitat for declining grassland species, requires anticipating the effects of increasing atmospheric carbon dioxide (CO2) concentrations and climate change on the region’s vegetation. Specifically, climate change threatens NGP grasslands by increasing the potential encroachment of native woody species into areas where they were previously only present in minor numbers. This project used a dynamic vegetation model to simulate vegetation type (grassland, shrubland, woodland, and forest) for the NGP for a range of projected future climates and relevant management scenarios. Comparing results of these simulations illustrates...

The mottled duck, a focal species for the Gulf Coast Prairie Landscape Conservation Cooperative, is one of only a few duck species adapted to breeding in southern marshes. A major part of its population spends its entire life cycle within a relatively small coastal area in eastern Texas and western Louisiana. This is a thriving part of the Mississippi and Central Flyways, two of four major waterfowl migration routes in North America. In recent years, the mottled duck’s habitat and surrounding areas have been compromised by urbanization, agricultural development, and changes to the area’s hydrology affecting coastal wetlands. The latter threat includes the ramifications of climate change, such as sea level rise and...

This project will support the use of the Breeding Bird Survey (BBS) data to calculate current populations, population trend, and ultimately desired population objectives for the priority species outlined in the IR 5/7 SHC Plan. Benchmarks will be estimated to highlight grassland and sagebrush habitat needed to support desired populations as outlined in the Partners in Flight Plan by 2050. The BCR specific population targets provide a solid foundation to continue to build and refine the R6 SHC Teams Work towards effective planning and ultimately effective on-the-ground conservation delivery. A $55,000 investment supports conservation priorities for both Grassland and Sagebrush Ecosystems.

Habitat loss and fragmentation are widely recognized as among the most important threats to global biodiversity. New analytical approaches are providing improved ability to predict the effects of landscape change on population connectivity at vast spatial extents. This paper presents an analysis of population connectivity for three species of conservation concern [swift fox (Vulpes velox); lesser prairie-chicken (Tympanuchus pallidicinctus); massasuaga (Sistrurus catenatus)] across the American Great Plains region. We used factorial least-cost path and resistant kernel analyses to predict effects of landscape conditions on corridor network connectivity. Our predictions of population connectivity provide testable...

The range-wide plan (RWP) has been developed in response to concerns about lesser prairie-chicken (LPC) habitat threats which may be impacting LPC populations, and the proposed listing under the Endangered Species Act (ESA). Along with the existing conservation efforts already being implemented, as described in the RWP, the supporting WAFWA Conservation Agreement (WCA) represents another mechanism to implement conservation to benefit LPC. The WCP represents an opportunity to enroll participants who agree to avoid, minimize and mitigate actions which may be detrimental to LPC. Landowners may enroll properties to be managed for the benefit of LPC. Properties may generate credits for mitigation. When complete avoidance...

Grassland birds have declined more rapidly than any other group of land birds in North America in the last 50 years, with populations of Spragues Pipit, Chestnut-collared and Thick-billed Longspur, and Bairds Sparrow having declined 65-94% during this period. Developing strategic conservation plans for grassland birds requires an understanding of their individual population ecology, along with their community dynamics amongst species. Few studies have focused on understanding how adult density during the breeding season relates to nesting performance (e.g., nest density and nest success) and how abiotic and biotic factors influence these individual demographics. This proposed work complements concurrent studies...

We developed multi-scale habitat suitability models for black-tailed prairie dogs (BTPD) in the southwestern Great Plains, corresponding to the western region of the Great Plains LCC. We used long-term (10-yr), high-resolution datasets on BTPD colony boundary locations collected at 7 study areas distributed across the region to develop resource selection functions based on colony locations and expansion patterns. Models are based on (1) soil maps and associated Ecological Sites (NRCS SSURGO database), (2) a topographic wetness index based upon water runoff and solar insolation patterns (TWIsi) that tests a priori hypotheses for topographic controls on BTPD, and (3) broad climatic gradients in temperature and mean...

Grassland birds have declined more rapidly than any other group of land birds in North America in the last 50 years, with populations of Spragues Pipit, Chestnut-collared and Thick-billed Longspur, and Bairds Sparrow having declined 65-94% during this period. This proposed cross-programmatic collaborative project between Migratory Birds and Refuges will expand on a growing network of Motus automated radio telemetry receivers (stations) to provide the first fine-scale quantitative assessment of the migratory period for regional priority grassland songbirds, which will inform key knowledge gaps about migration routes and stopover locations. Data collected via Motus automated telemetry tracking will allow the FWS and...

Populations of lesser prairie-chickens are proposed for listing as threatened or endangered. Lesserprairie-chickens require relatively intact, large grassland dominated habitats for population persistence. Successful conservation efforts require knowledge of potential landscape thresholds and grassland patch configuration affecting lesser prairie-chicken populations. We will use existing population survey, lek location, and data from >700 previously marked lesser prairie-chickens to determine the potential for the presences of large-scale landcover thresholds that influence occupancy and persistence of lesser prairie-chickens as well as testing effects of gradients of grassland composition and configuration within...

The desert grasslands of the southwestern United States support many wildlife species of management concern and economic value. The American pronghorn, for example, is a game species that contributes to local and state economies. Climate extremes, including severe droughts, heat waves, and atmospheric river events, are expected to occur more frequently in the Southwest. These extremes can affect the availability of food and water needed by wildlife. Wildlife management agencies and conservation organizations need information on resource availability for wildlife under future climate scenarios to design effective management strategies to sustain wildlife populations. Project scientists are working with the Arizona...
