A wide diversity of animals make their home in Theodore Roosevelt National Park. An abundance of native grasses provide sustenance for grazing animals both large and small while the tapestry of different habitats attracts a great number of birds. The terrain of the badlands creates microclimates of warm, dry slopes, relatively cool and wet juniper woodlands, and riverbottoms.

Amphibians - Very few amphibians eke out an existence in the harsh North Dakota climate.

Birds - More than 186 types of birds may be found living in or passing through Theodore Roosevelt National Park.

Mammals - Large grazing animals including bison, feral horses, elk, white-tail and mule deer, pronghorn, and small grazers such as prairie dogs share the range in the park.

Reptiles - Several varieties of snakes and lizards dwell in the semi-arid climate of western North Dakota.

Wildlife Management - The park works to keep the population of certain species balanced to maintain a healthy ecosystem.

You can learn more about the habitats that these animals use on the Natural Features & Ecosystems page. If you want to know where and when to look for animals in the park, check out the Wildlife Viewing page for advice.
