Plains Pocket Gopher (Geomys bursarius) lives in grassland prairies across Central North America. It feeds on grass and roots. Its conservation status is Least Concern.
Fascinating facts about the Plains Pocket Gopher
- A plains pocket gopher can add up to 2,059 cm of new tunnels each week, but it may also stop digging for several weeks during the summer. At any moment the animal maintains a network of about 30 to 50 m of tunnels, which it expands or contracts according to its energy budget. The system contains nests situated roughly 50 cm below the surface and lined with grass, as well as caches of roots and tubers.
- Its external cheek pouches can be turned inside-out for grooming, a feature that sets pocket gophers apart from other mammals. These fur-lined pouches open forward and are capable of carrying food items up to 7 cm long, allowing the gopher to transport roots and tubers without exposing its head. The ability to reverse the pouches also helps keep them clean while the animal works underground. This dual function supports both foraging efficiency and personal hygiene.
- Living in low-oxygen, high-carbon-dioxide burrows, the plains pocket gopher tolerates such conditions thanks to a very low resting metabolic rate of 0.946 ml O₂ per gram per hour. This reduced metabolism, together with high thermal conductance, lets the animal conserve oxygen and cope with limited airflow underground. The species also drinks little water, further adapting it to the sealed tunnel environment.
- The underground network created by plains pocket gophers becomes a bustling mini-ecosystem, housing insects such as flies, scarab and carrion beetles and cave crickets that live alongside the rodent's tunnels. Above ground, the gopher must remain vigilant because a range of predators - rattlesnakes, prairie kingsnakes, gopher snakes, feral cats, coyotes, foxes, badgers, hawks and owls - hunt it when it surfaces.
