These data represent a potential future condition of large block grasslands if CRP lands expire and the land-use reverts back to cropland. Data layers for 2022 and 2027 were calculated by reclassing CRP lands scheduled to expire prior to these years to cropland and recalculating the large block grasslands layer as described above.

These data represent Conservation Reserve Program (CRP) lands and their scheduled expiration date. CRP lands are those with a cropping history that have been enrolled in a program to plant grass cover for wildlife, erosion, and other benefits. CRP contracts are normally 15 years in length. These data are proprietary to the Farm Service Agency and are available to PLJV through an MOU that prohibits their dissemination. Analyses derived from these data will be available to refuge staff and MOUs may be developed in the future to share the data directly.

With extraordinary resolution and accuracy, Light Detection and Ranging (LiDAR)-derived digital elevation models (DEMs) have been increasingly used for watershed analyses and modeling by hydrologists, planners and engineers. Such high-accuracy DEMs have demonstrated their effectiveness in delineating watershed and drainage patterns at fine scales in low-relief terrains. However, these high-resolution datasets are usually only available as topographic DEMs rather than hydrologic DEMs, presenting greater land roughness that can affect natural flow accumulation. Specifically, locations of drainage structures such as road culverts and bridges were simulated as barriers to the passage of drainage. This paper proposed...

Habitat hotspots were mapped for migratory birds ‘guilds’ across the LCD region using species presence/absence data collected from citizen-science datasets and modelled habitat conditions from the LANDFIRE program (Rollins, 2009). For presence/absence data, we used the eBird Reference Dataset (ERD, accessed October 1st, 2016; summarized in Sullivan et al., 2009) to model guild-level response to prevailing vegetation structure (e.g., percent-cover grass, tree, shrub, vegetation height), topography, and water availability for priority migratory bird species outlined in the Rio Mora NWR Land Protection Plan. We parsed eBird species “checklists” for species observed within a ~ 500 kilometer radius of the Rio Mora NWR....

The wind energy development suitability product is a per-pixel (30 square-meters) model representation of the predicted probability (0.00-1.00) that an area can support wind energy development. The result is represented as a percentage, such that any value greater-than 0.5 would be classified as suitable for wind energy development in model space. To model suitability for wind energy development, we used 9,399 observations of ‘windmills’ taken from the FAA Digital Obstruction File (http://bit.ly/dof_12549; accessed June, 2016). Because the extent of the LCD region is limited to the panhandle region of Texas, we excluded all windmill observations outside of Texas from consideration during model building. To generate...

We used comparative landscape genetics to examine the relative roles of historical events, intrinsic traits and landscape factors in determining the distribution of genetic diversity of river fishes across the North American Great Plains. Spatial patterns of diversity were overlaid on a patch-based graphical model and then compared within and among three species that co-occurred across five Great Plains watersheds. Species differing in reproductive strategy (benthic vs. pelagic-spawning) were hypothesized to have different patterns of genetic diversity, but the overriding factor shaping contemporary patterns of diversity was the signature of past climates and geological history. Allelic diversity was significantly...

The tillage suitability product is a per-crop, per-pixel (30 square-meters) model representation of the predicted probability (0.00-1.00) that an area can support commodity crop development for a suite of crop types commonly grown in the LCD landscape. The values for each grid cell are interpreted as a probability, with any value greater-than 0.50 suggesting an area should be suitable for crop development based on observations of thousands of farmed areas around the LCD. To demonstrate composite suitability (“tillage”) for all crops, we added the individual probabilities for our modeled from cover classes (cereals, corn, cotton, and beans; described below), which represents the overall proportion of votes for “crop”...

Man-made water sources have been used as a management tool for wildlife, especially in arid regions, but the value of these water sources for wildlife populations is not well understood. In particular, the value of water as a conservation tool for Lesser Prairie-Chickens (Tympanuchus pallidicinctus) is unknown. However, this is a relevant issue due to a heightened conservation concern for the species and its occupancy of an arid landscape anticipated to experience warmer, drier springs and winters. We assessed if Lesser Prairie-Chickens would use commercially available wildlife water guzzlers and if there was any apparent selection between two design types. We confirmed that Lesser Prairie-Chickens would use bird...

Aerial surveys with locations, habitat type, and count estimates for Sandhill Cranes (Grus canadensis) and waterfowl. Waterfowl were distinguished between ducks, dark geese, and light geese. Habitat types described include: main channel, side channel, pond or wetland, and field adjacent to river, pond, or wetland. Crane and waterfowl habitat use was collected on the North and South Platte Rivers from the confluence of the North and South Platte River near North Platte, Nebraska to the Nebraska state line. Survey data was used to create habitat use models for ducks, geese, and sandhill cranes.

Priority and use segments for Sandhill Cranes (Antigone canadensis). Segments designated as use areas were utilized during annual spring surveys 2014-2016. Priority areas were determined using statistical modeling. The reduced model that best predicted use by Sandhill cranes included total area of trees, pits, crops and unvegetated sandbar habitats in each segments. Mean distance to conservation lands and roads and minimum distance to transmission lines and towers were also included in the model. Only distance to lines and total tree area had a significant (p < 0.05) relationship with priority core segments.

Stopover use by migrating shorebirds is affected by patch-level characteristics of habitat, but the relative influence of broadscale factors is poorly understood. We conducted surveys of ten 10-km-radius landscapes in north-central Oklahoma from 2007 through 2009 to examine the influence of the amount and composition of wetland habitats and surrounding land cover on shorebird use during migration. We used generalized linear modeling and an information-theoretic framework to identify factors that best explained species richness, total abundance, and abundance of four groups of shorebirds classified by breeding status and migration distance. Total abundance and richness both increased with the area of wetland...

Holocene environmental change is poorly characterized throughout much of the High Plains. Playa wetlands are sites with appreciable potential for reconstructing environmental change because of their environmental sensitivity. Radiocarbon, litho- and magneto-stratigraphic, and stable carbon isotope (δ13C) data for four playas on the Kansas High Plains indicate significant change occurred throughout the Holocene, which had profound impacts on playa ecosystem functions (e.g. groundwater recharge, surface water storage, and habitat). Minimum δ13C values and buried soils observed during the Pleistocene–Holocene transition suggest sufficient moisture to support vegetative cover and promote pedogenesis. Low magnetic susceptibility,...

To estimate wetland CEDs available in the future (2040) we used data from Bartuszevige et al. 2016 which estimates changes in playa functionality as a result of sedimentation, potential wind development, and tillage. Playas estimated to be impacted by these drivers were eliminated from the wetland landcover map and the process of calculating crane energy days described above was repeated.

Quantitative studies focusing on the collection of semibuoyant fish eggs, which are associated with a pelagic broadcast-spawning reproductive strategy, are often conducted to evaluate reproductive success. Many of the fishes in this reproductive guild have suffered significant reductions in range and abundance. However, the efficiency of the sampling gear used to evaluate reproduction is often unknown and renders interpretation of the data from these studies difficult. Our objective was to assess the efficiency of a modified Moore egg collector (MEC) using field and laboratory trials. Gear efficiency was assessed by releasing a known quantity of gellan beads with a specific gravity similar to that of eggs from representatives...

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...

These data represent the forecast saturated thickness of the Ogallala aquifer in 2050 based on the linear rate of depletion calculated previously. Using the model-based annual predictions of aquifer saturated thickness (described above), we built annual water-level transition matrices (e.g., Turner, 1987) that were then projected out through 2050.

Priority and use segments for waterfowl (ducks and geese). Segments designated as use areas were utilized during annual spring surveys 2014-2016. The reduced model for ducks indicated a relationship between total area of grass habitats, open water, crops, and wetlands, as well as mean distance to roads.
