Using the correct word matters.
The use of the term "overgrazing" when the facts actually call for the term "grazing" incorrectly presumes or represents that some level of grazing in the arid American West is benign—if not helpful—to native wildlife, water quantity, water quality and ecosystem function. But that is not the case.
Because of their numbers and pervasiveness across the landscape, the bovine has done more damage to the Earth than the bulldozer. This fact makes its all the more distressing that apologists for livestock grazing in natural ecosystems prefer to characterize the ecologically irritating agent as overgrazing rather than grazing. Such is to be expected because, after all, they are apologists. What is overdistressing is when scientists and public land managers also misuse the term overgrazing when what they are actually describing grazing.
One does not see the use of the term "overlogging" when describing harm done to forests by chainsaws and bulldozers. Nor does one see the term "overmining" or "overdrilling" to describe the activity of mineral extraction as a cause of degradation of land, water and wildlife. One does not read the term "overroading" in a discussion of landscape fragmentation.
Overgrazing is most appropriately used to describe the impacts of too much grazing in an area to maintain domestic livestock grazing, rather than in the context of sustaining functional ecosystems, intact watersheds and native species.
Sage-grouse, Pacific salmon, native trout, Mexican spotted owls, and numerous others species, as well as water quantity and water quality are all detrimentally affected by grazing long before soil loss becomes an issue. Even "light" grazing (if such could be done by 1,000-pound beast ill-bred for such environments) alters ecosystem composition and function.
The continued use of "overgrazing" rather than "grazing" to define the problem of grazing impacts on western public lands in the American West serves to shield that activity from needed scrutiny.
Andy Kerr (andykerr.net) is Czar of The Larch Company (www.andykerr.net), and consults for public lands conservation organizations in the American West, including those who seek to end abusive livestock grazing on public lands through the use of federal grazing permit buyouts, in which public lands grazing permittees are compensated for voluntarily relinquishing their permits back to the federal government, which then permanently retires the affected allotment from livestock grazing.
