Watershed protection. The public lands are managed to achieve optimum production of forage and water and to control erosion. Land treatment measures such as brush control, seeding, and contouring are being accomplished at a rate commensurate with available manpower and funds. In addition to these practices, the Bureau rehabilitates burned-over areas; develops water facilities, including wells, springs, reservoirs, and pipelines; builds water control structures ranging from small gully plugs to large water-spreading systems using detention dams, diversions, dikes, and water-spreaders; constructs range use facilities such as fencing, cattleguards, stocktrails, and truck trails; controls or eradicates noxious or poisonous plants and reseeds the land to usable forage. The Bureau also cooperates with other conservation agencies in watershed protection activities. 5. Forest and woodland management.
