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 2.5 million farmed areas around the LCD geography. To demonstrate composite suitability (“tillage”) for all crops, we added the individual probabilities for our modeled from cover classes (cereals, corn, cotton, and beans), which represents the overall proportion of votes for “crop” vs....

These data represent areas defined as large block grasslands according to a model developed by PLJV (McLachlan 2008). The model is based on literature derived Lesser Prairie-Chicken habitat preferences and considers habitat composition within a 2,000 ha area. Any pixel with more than 58% grass, less than 36% cropland, less than 2% woodland/ shrubland, less than 5 % secondary roads, and no 4 lane roads within a 2,000 ha surrounding area is counted as a large block grassland pixel.

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 aquifer saturated thickness product is a per-pixel (250 square-meters) model representation of the combined fluid and soil matrix volume of water available in a given area, represented in units of linear feet. The prediction of available water is made using a network of over 9,300 monitoring wells located throughout the High Plains aquifer region. These wells are part of an annually updated long-term water-level monitoring study being conducted by United States Geological Survey hydrologists and other partners (https://ne.water.usgs.gov/ogw/hpwlms/). We used the source well depth-to-water data, as well as information on the base elevation of the aquifer (USGS Report : ofr98-393), surface elevation (NED-DEM),...

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 the long term average (27 year) amount of duck energy days available in wetlands. Data were produced as part of the PLJV waterfowl implementation plan. We used data from recently completed studies investigating food resource availability in a variety of wetland types in the PLJV. Beheny (2017) completed a study of food energy availability in five different wetland types in northeastern Colorado. Clark (2016) investigated food resource availability in stock ponds in BCR 19 in Texas. For the wetland DED values reported in both studies, we assumed these values were appropriate for use across the whole Joint Venture region. We used Landsat 5 data to determine wetness frequency over 27 years (1985-2012)...

To estimate wetland DEDs 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 duck energy days described above was repeated.

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.

Monitoring is fundamental to wildlife management but rarely does it happen. Most often the challenges of funding, protocols, and qualified workers prove too great and most monitoring collapses in a few short years. This program functions to address these challenges and allows us to complete the wildlife management cycle of plan, implement and evaluate. The final step of monitoring is critical to understand the effects of management. Monitoring data also informs habitat delivery through development of decision support tools to target conservation actions. Accelerating loss of habitat and changing climate requires distributional information just to understand where to conserve species.

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...

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”...

DJ Case will work with PLJV and other project cooperators to develop, conduct, and analyze 14 focus groups with key landowners in six states within the GPLCC. Focus groups allow for open-ended discussions and follow-on questioning that will reveal the key socioeconomic realities and hurdles that discourage landowners from enrolling in conservation programs or restoring playas. Focus groups will be conducted in areas with large playa clusters as identified by PLJV’s science-based Playa Decision Support System. Researchers will select key landowners in each state for participation, and will use the focus group sessions to learn what landowners think and feel about management of their lands in general, and about conservation...

Playa wetlands are critical resources of the Great Plains, providing a range of ecological functions such as groundwater recharge, surface water storage, wetland habitat, and sediment filtering. As land cover has been converted from native grassland to cropland, playa ecological functions appear to have been dramatically impacted due to increased sediment delivery. This project will incorporate historical data to establish long-term trends in climate (primarily precipitation), watershed and playa land cover, buffer conditions, and playa sedimentation patterns. Previous studies have relied on relatively low-resolution spatial data and have focused primarily on contemporary land cover to establish spatial patterns...

These data represent the average annual depletion rate of the Ogallala aquifer from 1980 to 2009. These data were calculated by averaging spatially explicit 5 year depletion rates reported in McGuire et al. 2012.

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.
