The Hammonds case in eastern Oregon is the result of a political tug-of-war between ranchers and environmentalists. Congress’ willingness to cater to whichever happens to be most politically powerful has left public land management in a shambles and subject to repeated disputes like this one.
Two acts of Congress, one passed in 1978 and one in 2000, played hidden but key roles in the Hammonds’ case. The Public Range Improvement Act (PRIA) of 1978 was passed at the behest of ranchers, but ultimately it may have worked against them. The Steens Mountain Cooperative Management and Protection Act of 2000 was passed in response to environmental lobbying, and it probably generated much of the Hammonds’ hostility to the federal government.
When the Forest Service and later the Grazing Service (forerunner of the BLM) started regulating grazing, they established rules that were similar to rules the ranchers themselves had developed years before the agencies were created. These rules were much like those for mining and water, and included first-in-time, first-in-right and use-it-or-lose-it.
