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 does not significantly affect steer weights. While forage availability and use by cattle decreased in black-tailed prairie dog foraging areas, steer weight was not reduced significantly in either of two years of study at the USDA's Southern Great Plains Experimental Range near Woodward, Oklahoma. Nutrient cycling, increased soil fertility, and subsequent changes in forage quality partly compensated for reduced forage availability. Black-tailed prairie dogs were the most common prairie dog species collected in the wild for sale as exotic pets, until this trade was banned in 2003 by the United States federal government.
