"The Forest and Rangeland Renewable Resources Planning Act (RPA) of 1974, as amended, directs the Forest Service to prepare and update a renewable resources assessment that would include "a description of Forest Service programs and responsibilities , their interrelationships, and the relationship of these programs and responsibilities to public and private activities." The first description was part of the RPA Assessment document in 1979. The second was published as an independent support document in 1989. This third description is organized around major Forest Service programs within the National Forest System, State and Private Forestry, and Research and Development. Programs and responsibilities within International Programs, Law Enforcement and Investigations, Capital Improvement and Maintenance, along with Senior, Youth, and Volunteer Programs, are also discussed. Each section discusses major program areas, legal authorizations, administrative and organizational considerations, and relationships within the Forest Service and with outside organizations. A listing of major legislative authorities is provided."
