Roosevelt first came to the badlands in September 1883 on a hunting trip. While here he became interested in the cattle business and invested in the Maltese Cross Ranch. He returned the next year and established the Elkhorn Ranch.

Whenever he managed to spend time in the badlands, he became more and more alarmed by the damage that was being done to the land and its wildlife. He witnessed the virtual destruction of some big game species, such as bison and bighorn sheep. Overgrazing destroyed the grasslands and with them the habitats for small mammals and songbirds. Conservation increasingly became one of Roosevelt's major concerns. During his Presidency, Roosevelt established the US Forest Service and signed the 1906 Antiquities Act under which he proclaimed 18 national mounuments. He also established 5 national parks, 51 wildlife refuges and 150 national forests.

Here in the North Dakota badlands, where many of his personal concerns first gave rise to his later environmental efforts, Roosevelt is remembered with a national park that bears his name and honors thememory of this great conservationist.

Theodore Roosevelt National Park is in the colorful North Dakota badlands and is home to a variety of plants and animals, including bison, prairie dogs, and elk.
