The federal government is rewriting its rules governing ranching on public lands to increase the number of cattle, sheep and other livestock grazing on 155 million acres in the West, an area twice the size of New Mexico.

Public lands grazing is overseen by a nearly century-old system that heavily subsidizes some of the wealthiest Americans while doing little to address its harms to the environment, ProPublica and High Country News found last year.

Even though rangeland management experts say overgrazing has degraded public lands, the new rules being drafted by the U.S. Department of the Interior’s Bureau of Land Management — the first overhaul since 1995 — would instead expand the practice.

The proposed rules would also ratchet back public participation in the agency’s decisions to allow grazing on federal public lands. The BLM’s proposed updates would strictly limit who has a say and when they can object, eliminating many steps where the public has been able to observe and comment on decisions to issue or renew permits.
