Grazing Reform

Cows in damaged Little Lost River Valley allotment, Idaho

On more than 250 million acres of public lands in the American West, grazing by domestic livestock constitutes by far the most widespread human-caused impact on fundamental range conditions, including habitat quality, riparian functioning, and endangered species. More extensive than the impacts of logging and mining combined, commercial livestock grazing exacts an enormous toll on native ecosystems and wildlife throughout the American West. It is a contributing factor to the endangerment of 22 percent of all federally listed threatened and endangered species, and a major contributor to non-point source water pollution and desertification.

The U.S. Bureau of Land Management (BLM), the nation’s largest public lands-managing agency and administrator of grazing permits, is required to monitor the ecological impacts of grazing on its lands. BLM conducts evaluations of whether its grazing allotments meet “Land Health Standards” (LHS), but until now the results of these evaluations have been largely inaccessible to those outside the agency and their results have escaped independent review.

Our interactive map is based on these data from 2012, obtained via the Freedom of Information Act. PEER worked with a former BLM contractor to analyze what these records reveal about the condition of our public lands and BLM’s discharge of its duties to safeguard them.
