What's in a Name
National Park or National Forest
Arkansas also has many lakes created by the dams built by the U.S. Army Corps of Engineers (USACE). The Army is one of the armed services under the Department of Defense. Within the Army is the Directorate of Civil Works. The Civil Works programs include water resource development activities such as flood control, navigation, recreation, and infrastructure and environmental stewardship. The Little Rock District of the US Army Corps of Engineers administers the Arkansas areas.
Park Rangers for both the US Army Corps of Engineers and National Park Service wear uniforms of gray shirts and green pants. US Forest Service rangers usually wear khaki shirts and green pants. Shoulder patches and badges will be different.
Because they have different purposes, the agencies will administer even similar areas with very different rules. For example, national forests may provide trails for mountain bikes or off road vehicles; Buffalo National River does not. The Corps lakes allow motorized watercraft while Buffalo National River severely restricts motor use.
Because Buffalo National River adjoins Ozark National Forest, visitors need to pay attention to where they are. A legal activity in a forest may get you cited before a court of law in a park.
