The Bureau of Land Management oversees 245 million acres of public land across the U.S. More than 60% of that rangeland is being managed through leased livestock grazing allotments in Oregon and nine other Western states. But according to the nonpartisan Public Employees for Environmental Responsibility, livestock grazing is the main reason why nearly 60 million acres of BLM rangeland fail the agency’s own standards for land health, which are used to assess soil and water quality, among other factors. High Country News recently reported on PEER’s findings, which also found that BLM state offices are increasingly relying on a federal loophole to renew grazing permits and leases without environmental review, especially in Oregon, Nevada and Idaho. 

Peter Lattin is a landscape ecologist, geospatial analyst in Oregon who was working for a contractor that was hired by BLM in 2010 to conduct regional ecological assessments. He resigned from his position when he was told by BLM officials not to include the impact of livestock grazing on land health assessments. He then shared his concerns with PEER and worked with the organization to obtain BLM records through the Freedom of Information Act. Lattin and PEER used that data to create an interactive map that shows the impact of livestock grazing on public land. Chandra Rosenthal is the director of PEER’s Rocky Mountain office in Denver. They join us to talk about their findings.
