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 monuments. 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 the memory 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.
