What the GAO found:
The 10 federal agencies managed more than 22.6 million AUMs on about 235 million acres of federal lands for grazing and land management in fiscal year 2004. Of this total, the Department of the Interior’s Bureau of Land Management (BLM) and the U.S. Department of Agriculture’s Forest Service managed more than 98 percent of the lands used for grazing. The agencies manage their grazing programs under different authorities and for different purposes. For BLM lands and western Forest Service lands grazing is a major program; the eight other agencies generally use grazing as a tool to achieve their primary land management goals. In fiscal year 2004, federal agencies spent a total of at least $144 million. The 10 federal agencies spent at least $135.9 million, with the Forest Service and BLM accounting for the majority. Other federal agencies have grazing-related activities, such as pest control, and spent at least $8.4 million in fiscal year 2004. The 10 federal agencies’ grazing fees generated about $21 million in fiscal year 2004—less than one-sixth of the expenditures to manage grazing. Of that amount, the agencies distributedabout $5.7 million to states and counties in which grazing occurred, returned about $3.8 million to the Treasury, and deposited at least $11.7 million in separate Treasury accounts to help pay for agency programs, among other things. The amounts each agency distributed varied, depending on the agencies’ differing authorities. ...
