Livestock grazing in the arid West is a major cause of species endangerment. Among 1,207 plant and animal species listed as endangered, threatened or proposed for listing, 11% are impacted by mining, 12% by logging and 22% by livestock grazing (Wilcove et al. 1998).
In the eleven western states approximately 254 million acres of federal
public lands managed by the U.S. Forest Service and the Bureau of Land
Management are grazed by domestic livestock—an area more than eighty-one
times that of Connecticut. Grazing also occurs on many wildlife refuges, and
units of the National Park Service, among them Grand Teton National Park
(WY) and Great Basin National Park (NV).
These federal lands encompass a wide diversity of ecosystem types including
creosote bush deserts, blackbrush deserts, slickrock mesas, sagebrush flats,
pinyon-juniper woodlands, chaparral, ponderosa pine forests, and alpine
meadows above timberline. Unlike Midwest prairies, these are areas which,
during the past 10,000 years or so, have not been subject to intense grazing
pressure from large herds of large ungulates. Hence the grasses in these
regions have not evolved mechanisms (such as asexual means of reproduction)
to protect themselves from such grazing.
Consequently, livestock grazing in the arid West is a major cause of species
endangerment. Among 1,207 plant and animal species listed as endangered,
threatened or proposed for listing, 11% are impacted by mining, 12% by
logging and 22% by livestock grazing (Wilcove et al. 1998). Here are a few
example impacts drawn from the survey paper by Tom Fleischner (1994):
Livestock, of course, typically impact wildlife through alteration of
habitat. Although such alterations take different forms in different
ecosystems, there are few as surprising as this one summarized in the
above-mentioned article by Fleischner: In central Washington, grazing was
responsible for changing the physical structure of ponderosa pine forest
from an open, park-like overstory with dense grass cover to a community
characterized by dense pine reproduction and lack of grasses. Similar forest
conversions have been documented elsewhere in the West, and indicate that
even if poor logging practices such as high-grading and clearcutting are
eliminated from our forests, livestock grazing alone will lead to a decline
in forest health and an increase in catastrophic fires.
Can Better Livestock Management Correct These Problems?
Some proponents of the livestock industry (e.g., Knize 1999) have claimed
that environmental degradation resulted from long-abandoned grazing
practices that have now been replaced by "ecologically sensitive" methods
that actually benefit native plants and wildlife. (See Savory (1988) for
details.) Sadly, despite anecdotal reports of great environmental
improvement with these methods, they have not stood up well to scientific
scrutiny.
For example, Pieper and Heitschmidt (1988: 135) confront the fundamental
claims of Allan Savory by examining a major component of his grazing
management system. His claims being “… that dramatic improvements in range
condition would occur following proper implementation of a short-duration
grazing system … and … that both rate of improvement and individual animal
performance would be enhanced as stocking rate increased.” Since the time of
Savory’s claims “… a considerable number of scientific studies have been
completed that specifically address the effects of short-duration grazing on
above-ground forage dynamics, hydrologic integrity, and livestock
performance. … In general, these studies do not support the claims that
prompted the research.”
Economic Benefits from Grazing Livestock on Federal Lands?
In the 11 western states, ranching on federal public lands provides less
than 18,000 jobs (0.06% of total jobs) and 0.04% of the income (Power 1996:
Table 8-2). Only about 22% of ranchers in these states even hold federal
grazing permits (BLM and USDA 1994: 3-65). On a national basis, these
ranchers represent only 2% of America’s 1.1 million cattle operators,
producing only 3.8% of the nation’s beef cattle, according to the U.S.
Department of Agriculture (Rogers and LaFleur 1999).
Why Should Non-Westerners Care What Occurs on Western Public Lands?
Aside from the extensive damage caused by livestock to western
ecosystems—loss of clean water, increased soil erosion, decline of forest
health, loss of native plants and decreases in wildlife populations—our
federal taxes subsidize the very presence of livestock on these lands. A
recent investigation by reporters from the San Jose Mercury News revealed
that the U.S. Forest Service and BLM together spent $94 million more on
their grazing programs in 1998 than they collected in fees from ranchers
(Rogers and LaFleur 1999).
Other investigators claim the subsidies are even greater. Regarding just the
western lands managed by the Bureau of Land Management, Nelson (1996: 4)
placed the annual cost of the grazing program at $200 million, although
ranchers paid only $20 million through their grazing permits. He also
reported that the annual value of the forage coming from these lands was
approximately $65.3 million—a good deal for the ranchers, but an economic
disaster for taxpayers, who are paying almost three times more than the
product is worth.
Hess and Wald (1995), considering both direct and indirect governmental
subsidies to the western livestock industry, estimate their cost at $500
million annually.
An End to Public Lands Ranching?
Many people believe that it is time to begin looking at legislative
solutions that will phase out livestock grazing on federal public lands. The
environmental impacts and taxpayer subsidies are simply not justified by the
meager economic benefits, nor by the value to the nation of the beef coming
from these lands.
Where to Learn More
In the past few years several survey articles have been written about the
environmental impacts of livestock grazing on western ecosystems. These
summaries are excellent resources for anyone wanting to better understand
these issues, but who do not wish to read hundreds of research papers. Here
are three of my favorites:
Readers with access to the Internet can find a wealth of information about public lands ranching on the RangeBiome website. In addition to essays and archived news articles, the website provides links to dozens of livestock-related websites throughout the U.S.
