Greatest-density regions for GPS locations of bison (Bos bison) at Tallgrass Prairie National Preserve, 2021-2023 Greatest-density regions for GPS locations of bison (Bos bison) at Tallgrass Prairie National Preserve, 2021-2023
This GIS shapefile, "density_contours," describes 1) a bison study area at Tallgrass Prairie National Preserve, Kansas, and 2) 25%, 50%, 75%, and 99% kernel density contours for locations of bison marked with GPS collars during 2021-2023. Percentages associated with contours describe nominal coverage, i.e., proportions of observations they are expected to encompass, and approximate the
