Mexican prairie dog Mexican prairie dog The Mexican prairie dog ("Cynomys mexicanus") is a diurnal burrowing rodent native to Mexico. Treatment as an agricultural pest has led to its status as an endangered species. They are closely related to squirrels, chipmunks, and marmots. "Cynomys mexicanus" originated about 230,000 years ago from a peripherally isolated population of the more widespread "Cynomys ludovicianus". These prairie dogs prefer to inhabit rock-free soil in plains at an altitude of . They are found in the regions of southern Coahuila and northern San Luis Potosí in northern Mexico, where they eat herbs and grasses native to the plains
Black-tailed prairie dog activities keep plant development in a suppressed vegetative state with higher nutritional qualities, herbivores, including red deer ("Cervus elaphus"), American bison, pronghorn ("Antilocapra americana"), and domestic cattle often prefer foraging in black-tailed prairie dog colonies. Animals that depend on herbaceous cover in sagebrush habitat, such as mule deer ("Odocoileus hemionus") and sage grouse ("Centrocercus" spp.), may be deterred by the decreased vegetative cover on black-tailed prairie dog colonies.

Biodiversity in shortgrass prairies may be at risk due to the reductions in distribution and occurrence of black-tailed prairie
