PrairieMap is a geospatial data clearinghouse supporting research, management, and conservation of prairie grassland ecosystems in western North America. Approximately 1600 data layers are available for download from the PrairieMap site. Data layers comprise an extensive variety of themes, including landcover, wildlife, transportation, boundary, fire, utilities, hydrology, soils, topography, and others.
PrairieMap addresses the need for accessible data and information about prairie habitats and many of their associated wildlife populations. Developed in collaboration between ecologists, wildlife biologists, land managers, and geographic information professionals, PrairieMap is at core a public-access catalogue of geospatial datasets in support of greater, spatially-sensitive understanding of short-grass, mixed-grass, and tall-grass prairie ecosystems in the western United States and Canada.
