The BLM conducts National Scenic or Historic Trail Feasibility Studies, administers National Scenic or Historic Trails upon designation by Congress, and defines the responsibilities of National Scenic or Historic Trail Administrators. In addition there are requirements for the management of trails undergoing National Trail Feasibility Study; trails that are recommended as suitable for National Trail designation through the National Trail Feasibility Study; inventory, planning, management, and monitoring of designated National Scenic and Historic Trails. For National Recreation Trails (including the National Water Trails) and Connecting and Side Trails, BLM requirements include cooperative relationships; trail marking; identifying, evaluating and recommending trails; nominating trails through the submission of application packages; and data and records management.
