About a quarter of the land in the United States is federal, managed by four agencies with four different missions. What is allowed on a given acre (grazing, mining, logging, motorized travel) depends on which agency manages it and under which statute.
This section compares the agencies by the uses they allow, then explains the statuses that change those rules: wilderness, national monuments, roadless areas. It also covers the tools of forest management, from timber sales to prescribed fire.
