The Myth About Livestock Waters on Western Public Lands

Several years ago I accompanied some U.S. Forest Service staff on a horseback inspection of a livestock grazing allotment located in the arid Superstition Mountains of the Tonto National Forest in central Arizona. As we neared a muddy stock tank perched on a chaparral-covered hill we scared off several mule deer that were taking a drink. The District Ranger turned toward me in his saddle and told me how glad he was that livestock were allowed to graze public lands, because the deer would be scarce if there weren’t any livestock waters.

The theory that the wildlife species native to the West’s arid ecosystems depend upon livestock waters for their survival is a popular one. Many federal land managers are willing to believe it. Their environmental assessments of grazing allotment management plans often warn that eliminating livestock grazing would harm local wildlife populations because the livestock waters wouldn’t be maintained.

Most ranchers also seem to believe it, and they frequently offer it in defense of livestock grazing on public lands. I’ve even had ranchers tell me there was hardly any wildlife in Arizona before ranchers arrived and “improved” the land, which is, of course, ridiculous (Davis 1982).

The idea that wildlife depend upon livestock waters is so prevalent there’s a conservation group called the Arizona Desert Bighorn Sheep Society that works with the Arizona Game and Fish Department (AGFD) to try and increase bighorn sheep numbers by constructing permanent water holes in the Sonoran desert.

Statewide, the AGFD maintains more than 725 wildlife waters at an estimated annual expense of about $400,000.

Despite all this, there’s surprisingly little scientific evidence to support this belief – and much that contradicts it. Even long-time proponents of livestock waters question their effectiveness (Brown 1997; Krausman 1997). For instance, a review of the AGFD bighorn sheep water development program (Broyles 1995) conducted in the Cabeza Prieta National Wildlife Refuge concluded, “It has not been shown that these developments are necessary, beneficial, or without harmful side effects.”

Another study conducted in southern New Mexico (Burkett and Thompson 1994) compared wildlife populations at 20 sites that had man-made waters with the same number of similar sites lacking permanent surface water. They found that, “definitive effects of artificial water sources on native wildlife species were not detectable.”

And another study conducted in Arizona’s Sonoran Desert  (Krausman and Etchberger 1995) looked at desert mule deer and bighorn sheep populations in the area of the Central Arizona Project canal before and after its construction. They found that, “additional water was not important to the deer or sheep populations.” And a more recent study of mule deer distribution in arid environments (Marshall 2006) found that forage quality was the most important habitat component, and additional livestock waters had little effect.

There are also studies suggesting livestock waters may have negative effects upon native wildlife. For example, they may provide habitat for invasive fish, bullfrogs, and crayfish that can get washed into streams during floods (Sponholtz 1997), and non-native species are the primary factor in the decline of native fish and amphibian species in the West (Simms 1997).

Building new livestock waters in upland areas is often justified by claiming they will lure cattle away from ecologically important riparian bottomlands. But cattle are bred to be lazy critters and are unlikely to climb a sunny hill in the heat to get a drink when the they can stay in the shade of a tree along a stream. Research has shown (Carter 2017) that upland water sources in the arid West don’t attract enough cattle out of riparian areas to allow these important habitats to achieve full ecological health.

The construction of new livestock waters is also used to improve livestock distribution on the uplands. The idea is to spread out the livestock more evenly to reduce overgrazing in areas where the animals like to congregate. It can help overused areas recover from overgrazing, but it can also bring the negative ecological impacts of grazing to new areas that were historically too dry for livestock use (McAuliffe 1997).

Still, the idea that more water means more wildlife sounds intuitively good. It’s an easy concept for hunters and hikers to believe because they know one of the best places to spot wildlife is around water holes. But just because animals congregate around water holes doesn’t mean they’re relying on that water source for their survival. For example, how often have you stopped to take a drink from a water fountain just because it was convenient?

But what about all of those biologists warning us the majority of the West’s wildlife depend, in some way, upon riparian areas for their survival? Livestock waters rarely support significant amounts of riparian habitat. Many of them are so trampled by cattle they are considered ecological sacrifice zones.

Numerous studies have shown it’s the amount and quality of suitable habitat that has the most influence upon wildlife populations. For instance, AGFD research showed that Gambel’s quail (Callipepla gambelli) don’t need surface water, and the quantity and quality of forage was the most important limiting factor on quail populations (Gallizioli 1961). In other words, water is just one component of wildlife habitat, and most Western U.S. wildlife species are adapted to its scarcity.

Of course, there are always exceptions. Elk, for instance, behave much like cattle and livestock waters constructed by ranchers have helped them inhabit hotter and drier areas where they were historically scarce or nonexistent. It’s ironic, because ranchers often complain that local elk populations need to be reduced because they’re competing directly with their cattle for available forage.

The bottom line is the ecological effects of building livestock waters should be objectively considered. Sufficient vegetation to provide quality cover and forage appears to be more important than surface water for most arid land wildlife species. New livestock waters are very expensive and on public lands they are typically built with public funds. In most situations, it would be cheaper for the taxpayers if federal land managers would simply cut permitted livestock numbers to achieve natural resource goals.

Dakota Access Pipeline Victory May Only Be Temporary

Dakota Access Pipeline
Oil Pipeline Construction (Wikipedia)

Protestors trying to stop construction of the Dakota Access Pipeline (DAPL) near the Standing Rock Indian Reservation in North Dakota were victorious on December 4, 2016, when the U.S. Army Corp of Engineers refused to permit the pipeline to carry dirty Canadian tar sands oil beneath Lake Oahe.  The U.S. State Department had previously approved the pipeline with a controversial determination that it wouldn’t substantially increase greenhouse gas emissions.

The protests against the DAPL began in April when members of the Standing Rock Sioux tribe established the Sacred Stone Camp to accommodate pipeline protestors near the mouth of the Cannonball River, where it empties into the lake. The primary objective of the protestors was to protect the lake from oil spills because it’s the source of the tribe’s water supply.

They used the slogan, “Water is Life.” But their protest soon grew into much more, and became a worldwide focal point for indigenous rights and climate change activists. Thousands of people joined the camp, including representatives from hundreds of tribes, making it the largest gathering of Native Americans in more than a century. About 2,000 veterans of the U.S. military also traveled to the camp intent on forming a human shield to protect the protestors from police attacks.

The National Environmental Policy Act (NEPA)

The Corp of Engineers explained they were denying a pipeline easement beneath the lake so they could conduct a full-blown environmental impact statement (EIS) in which alternative routes would be explored. An EIS is the most rigorous type of environmental study mandated by the National Environmental Policy Act (NEPA), which was signed into law by Republican President Richard Nixon in 1970. NEPA requires federal agencies to complete environmental studies of all their projects, using a public participation process that analyzes the environmental effects of various alternatives.

The Corp of Engineers has a say in whether a pipeline can be permitted beneath Lake Oahe because it has jurisdiction over public waterways and the lake is a reservoir on the Missouri River. The Corp had already completed an environmental assessment (EA) for the DAPL, a less rigorous type of NEPA study that’s typically used for projects with fewer significant issues. But the Environmental Protection Agency (EPA), the Department of the Interior, and the Advisory Council on Historic Preservation considered an EA to be inadequate for this project, and asked the Corp to complete an EIS.

The incoming Trump administration, however, will probably try to make the Corp reverse their decision to conduct an EIS, or even worse, work with the Republican-controlled Congress to revoke or eviscerate NEPA. This would have serious consequences on U.S. public lands administered under the multiple use doctrine by the Forest Service and Bureau of Land Management (BLM). The Forest Service, an agency within the U.S. Department of Agriculture, manages the nation’s 154 national forests and 20 national grasslands – comprising about 193 million acres. The BLM, an agency of the U.S. Department of the Interior, manages about 30 million acres, including 221 wilderness areas and 23 national monuments. NEPA is the primary mechanism by which Americans participate in the management of these lands because it requires federal land management agencies to conduct publicly reviewed environmental studies for their plans and projects. Without NEPA, the public would have little or no effective input on proposed mining operations, drilling operations, timber cuts, recreational activities, or livestock grazing schemes.

The scope of the potential danger is best illustrated by taking a closer look at the situation in regards to livestock grazing on public lands. The BLM administers more than 21,000 public lands grazing allotments, while the Forest Service has almost 6,000 grazing permittees. Public lands grazing is, by far, the most ubiquitous use of U.S. public lands, occurring on more than 200 million acres, mostly in the West. Subsequently, it’s also the commercial activity that inflicts the most widespread ecological damage on public lands. Even with NEPA, the public typically gets to review and comment on a grazing operation just once every 10 years – the term of a federal grazing permit. Without NEPA, even that modest opportunity would be gone.

But death of NEPA as we know it would do more than threaten the ecological health of hundreds of millions of acres of public lands. As mentioned above, a NEPA study must also be conducted when a proposed project might adversely affect a public waterway, even when the project is located on private land.

These are just some of the examples of the importance of the National Environmental Policy Act. It’s often been referred to as the environmental Magna Carta because its stated purpose is to “encourage productive and enjoyable harmony between man and his environment; to promote efforts which will prevent or eliminate damage to the environment and biosphere and stimulate the health and welfare of man; to enrich the understanding of the ecological systems and natural resources important to the Nation.” If the Trump administration and the Republican Congress are allowed to neutralize NEPA, the U.S. will have crossed over an ideological threshold to a dark domain where the only thing that really matters is money.

Update

In January of 2017 newly elected President Donald Trump issued an executive order to make the U.S. Army Corp of Engineers reverse their decision under the Obama administration to complete a full-blown environmental impact statement (EIS) of alternative routes for the DAPL, and then had them issue a permit to allow the pipeline to be drilled beneath Lake Oahe.

On June 14, 2017, federal judge James Boasberg ruled that the Corp of Engineers was, indeed, required to complete an EIS for the DAPL on the Standing Rock reservation. The pipeline, however, had already been built and the judge didn’t order it to be shut down while the EIS is completed.

Many conservatives believe that Republican candidate John McCain would have beaten Barack Obama in the 2008 presidential election if he just hadn’t chosen Sarah Palin to be his running mate. And many of them also believe that Republican Mitt Romney would have beaten Obama in the 2012 election if the “truth” about the September, 2012, attack by Islamic militants against American diplomats in Benghazi, Libya, had been revealed during the campaign. Their unwavering conviction in these beliefs is derived from their certainty that their policies are superior.
