Prairie dogs are keystone species that impact both animals and plants in grassland habitats. They are a food resource for secondary consumers such as badgers, foxes, and raptors. Also, the mounds that they construct are home to many arthropod and reptile species that otherwise might not survive in grasslands. Both Gunnisonâ€™s and black-tailed prairie dogs can increase the number of plant species in grasslands and landscape heterogeneity with their ecosystem engineering that creates disturbed patches on the landscape. Gunnisonâ€™s prairie dogs, which were native herbivores at the Sevilleta National Wildlife Refuge (NWR) before their populations disappeared, were reintroduced at the Sevilleta NWR in 1997, 2005, and 2008. In 1998, a Gunnisonâ€™s prairie dog colony naturally established along the northern border on the east side of the Refuge. The naturally occurring colony and the colony that was reintroduced in 1997 have since then severely declined or gone locally extinct. Still, with the removal of cattle from the Sevilleta in 1973, the reintroductions of Gunnisonâ€™s prairie dogs in 2005 and 2008 provides an interesting opportunity to study how a native keystone herbivore affects a grassland habitat without the pressures and competition from livestock.
