Utah Prairie Dog (Cynomys parvidens) lives in grassland prairies across Southwest North America. It feeds on grass and seeds. Its conservation status is Endangered.
Fascinating facts about the Utah Prairie Dog
- Utah prairie dogs are the tiniest of their kind, measuring just 30.5-36 cm long and weighing as little as 0.64 kg in females. Males tip the scales at up to 1.41 kg, making them 27 % larger than the opposite sex. Their size swings with the seasons, ranging from 0.3-0.9 kg in spring to 0.5-1.5 kg in summer for males. predators like badgers and raptors.
- From 1920's 95,000 individuals to a 1972 estimate of just 3,300 across 37 colonies, the Utah prairie dog has lost roughly 96 % of its historic population. By 2004, spring surveys counted 4,022 animals, a figure thought to represent only half of the living total. This dramatic decline, driven by habitat loss, poisoning, and plague, underpins its Endangered status and fuels intensive recovery plans aimed at restoring numbers by 2040.
- Utah prairie dogs dig burrows at least 1 m (3.3 ft) deep in well-drained soil, creating underground chambers that aerate the earth and boost nitrogen uptake for surrounding plants. Their tunnels also provide homes for rabbits, badgers, ground squirrels, and burrowing owls, making the dogs a keystone engineer that shapes habitat complexity and supports a web of other species.
- Each Utah prairie dog produces only one litter per year, averaging 3.88 pups, and the size of that litter scales with the mother's body mass. Females experience a single, brief estrus lasting just a few hours in mid-March to early April, yet 97 % of adult females are ready to breed each season.
- Utah prairie dogs hibernate for four to six months, retreating underground from late November until late February. Males begin their dormancy in August or September, with females following weeks later, while juveniles stay active up to two months longer.
