Quality data underlies all of our geospatial tools. While we have many ways to view and interact with those data, you can also download the following data layers to your computer.
Probable Playas Data Layer
PLJV’s regional playa dataset is a compilation of several original data sources including the National Wetlands Inventory, Soil Survey Geographic database, and satellite imagery. These wetland data were analyzed for each state in the PLJV region — Colorado, Kansas, Nebraska, New Mexico, Oklahoma and Texas — to create the most comprehensive playa location map possible using remote sources. The playas layer contains locations of more than 70,000 playas across the PLJV region.
Playa Clusters Data Layer
Playa clusters represent groups of playas that likely provide increased benefits to wildlife as compared to playas that are more sparsely distributed. Research shows that clusters of playas are more frequently used by migrating waterfowl and shorebirds than sparsely distributed playas (Farmer and Parent 1996, Brennan 2006, Cariveau and Pavlacky 2008, Webb et al. 2010). Playa clusters were defined by identifying areas with either high playa density or high playa surface area, according to duck abundance data collected on playas.
Woody Encroachment Data
These woody encroachment layers capture the spread of shrubs at high and low densities using high-resolution NAIP satellite imagery provided by USGS and USDA. The spread of woody species into grass-dominated, prairie ecosystems in the central plains is a persistent threat. Within the PLJV region, on an annual basis, we lose an average of 1-4% of our grasslands to woody encroachment. In the south, conversion is driven by honey mesquite and, in some areas, Ashe and redberry juniper. In the north, grassland conversion is driven largely by eastern redcedar.
