Grasslands are among the most imperiled ecosystems in the world where the loss of native species is a consequence of agriculture and desertification. In North America, 90% of the grassland has been converted to cropland where vast areas are now desertified. North America's most iconic grassland herbivores, bison and prairie dogs, are now extinct throughout most of their historic range. This study measures the standing crop of plant vegetation (perennial and annual combined) for the year on areas occupied and not occupied by Gunnison's prairie dogs on the Sevilleta National Wildlife Refuge (NWR).
