When it comes to the U.S. conservation movement, few people have been as instrumental as Theodore Roosevelt. The former president set aside many lands as national parks and monuments and also made it easier for future presidents to establish national parks and conservation areas. Theodore Roosevelt National Park, which is located in western North Dakota, is named to commemorate the conservationist’s efforts to preserve the nation’s natural landscapes. Roosevelt first visited the area that is now the national park during his youth, and he returned to hunt and ranch in the region in his pre-presidential years. The park's badlands landscapes and abundant wildlife — including bison, deer, wild horses, prairie dogs, turkeys and eagles — draw a number of outdoor enthusiasts.
