RENO, Nev. — A scathing independent scientific review of wild horse roundups in the West concludes the U.S. government would be better off investing in widespread fertility control of the mustangs and let nature cull any excess herds instead of spending millions to house them in overflowing holding pens.

A 14-member panel assembled by the National Science Academy’s National Research Council, at the request of the Bureau of Land Management, concluded BLM’s removal of nearly 100,000 horses from the Western range over the past decade is probably having the opposite effect of its intention to ease ecological damage and reduce overpopulated herds.

By stepping in prematurely when food and water supplies remain adequate, and with most natural predators long gone, the land management agency is producing artificial conditions that ultimately serve to perpetuate population growth, the committee said Wednesday in a 451-page report recommending more emphasis on the use of contraceptives and other methods of fertility control.

The research panel sympathized with BLM’s struggle to find middle ground between horse advocates and ranchers who see the animals as unwelcome competitors for forage. It noted there’s “little if any public support” for allowing harm to come to either the horses or the rangeland itself.

The report says the current method may work in the short term, but results in continually high population growth, exacerbating the long-term problem.

The American Wild Horse Preservation Fund, a national coalition of more than 50 advocacy groups, said the report makes a strong case for an immediate halt to the roundups that livestock ranchers say are necessary to protect the range and provide their sheep and cattle with a fair share of forage.

“This is a turning point for the decades-long fight to protect America’s mustangs,” said Neda DeMayo, president of the coalition’s Return to Freedom.

The National Cattlemen’s Beef Association is among the livestock groups that have voiced support in the past for aggressive, increased use of fertility control but remain adamantly opposed to curtailing roundups. Horse advocates themselves are not united behind the idea of stepping up use of contraception on the range.

“We are grateful that the National Academy of Science recommends stopping cruel roundups, but we challenge their decision to control alleged overpopulation like a domestic herd with humans deciding who survives and breeds,” said Anne Novak, executive director of Protect Mustangs in San Francisco.

The conflict has raged for decades but has intensified in recent years for cash-strapped federal land managers with skyrocketing bills for food and corrals and no room for incoming animals.

“The business as usual practices are not going to be effective without additional resources,” said Guy Palmer, a pathologist from Washington State University who chaired the research committee.

Rep. Raul Grijalva, D-Ariz., said the report should serve as a wakeup call to bring changes he and others in Congress have urged for years.

“These unsustainable practices are a waste of taxpayer money and jeopardize the health and safety of wild horses across the West,” he said.

BLM officials said they welcomed the recommendations to help in their effort to make the program more cost-effective. Spokesman Tom Gorey said the agency “needs and wants to do a better job” managing horses, but said those advocating an end to all roundups are misguided.

“It appears that our critics want to use the report as a propaganda tool to stop gathers,” which the BLM are required to do by law, Gorey said.

“Do the American people and does Congress support changing the law so that BLM would carry out a laissez-faire management policy that would subject horses and burros to mass starvation or dehydration by letting Mother Nature work her will?” he asked in an email to The Associated Press.

Panel members said they found little scientific basis for establishing what BLM considers to be appropriate, ecologically based caps on horse numbers and even less basis for estimating the overall population itself.

“It seems that the national statistics are the product of hundreds of subjective, probably independent, judgments and assumptions by range managers and administrators,” the report said.

BLM’s current population estimate likely is anywhere from 10 percent to 50 percent short of the true level, the report said.

The number of animals at holding facilities surpassed the estimated number on the range in 10 Western states earlier this year for the first time since President Richard Nixon signed the Free-Roaming Horses and Burros Act of 1971.

The agency averaged removing 8,000 horses from the range annually from 2002 to 2011. Last year, it spent 60 percent of its wild horse budget on holding facilities alone, more than $40 million, the committee said.

Palmer said the public traditionally adopted about 3,000 of the horses annually but that has fallen off in recent years.

“The goal would be to manage horses better on the range so that any numbers that would be taken off would be matched with the adoption demand, which is not the current case.”

RENO, Nev. – A scathing independent scientific review of wild horse roundups in the U.S. West concludes the government would be better off investing in widespread fertility control of the mustangs and let nature cull any excess herds instead of spending millions to house them in overflowing holding pens.

BLM officials said they welcomed the recommendations in their effort to make the program more cost-effective but had no immediate reaction to the criticisms.

“Our agency is committed to protecting and managing these iconic animals for current and future generations,” Deputy Director Neil Kornze said.

Compounding the problem is a horse census system and rangeland assessment practice rife with inconsistencies and poor documentation, the committee said, noting a previous NRC committee charged with the same task reached the same conclusion 30 years ago.

Panel members said they found little scientific basis for establishing what BLM considers to be appropriate, ecologically based caps on horse numbers and even less basis for estimating the overall population itself.

“It seems that the national statistics are the product of hundreds of subjective, probably independent, judgments and assumptions by range managers and administrators,” the report said.

BLM’s current population estimate likely is anywhere from 10 per cent to 50 per cent short of the true level, the report said.

National Academy of Science Report on Wild Horses and Burros

Cross-posted from: http://www8.nationalacademies.org/onpinews/newsitem.aspx?RecordID=13511

NATIONAL ACADEMY OF SCIENCEDate:  June 5, 2013FOR IMMEDIATE RELEASE:New Report Offers Science-Based Strategies for Management of Western Free-Ranging Horses and Burros; ‘Business-as-Usual’ Practices Will Be Increasingly Expensive and Unproductive for BLM

 

WASHINGTON — The U.S. Bureau of Land Management’s (BLM) current practice of removing free-ranging horses from public lands promotes a high population growth rate, and maintaining them in long-term holding facilities is both economically unsustainable and incongruent with public expectations, says a new report by the National Research Council.  The report says that tools already exist for BLM to better manage horses and burros on healthy ecosystems, enhance public engagement and confidence, and make the program more financially sustainable.  It also provides evidence-based approaches that, if widely and consistently implemented, can improve the management of these animals on public lands in the western U.S.

 

The committee that wrote the report determined that most free-ranging horse populations are growing at 15 percent to 20 percent a year, meaning these populations could double in four years and triple in six years.  With no intervention by BLM, the horse population will increase to the point of self-limitation, where both degradation of the land and high rates of horse mortality will occur due to inadequate forage and water.  In addition, periodic droughts, many of them severe, in the western public lands cause immediate and often unpredicted impacts.  There is little if any public support for allowing these impacts on either the horse population or the land to take place, and both go against BLM’s program mission.  However, the current removal strategy used by BLM perpetuates the overpopulation problem by maintaining the number of animals at levels below the carrying capacity of the land, protecting the rangeland and the horse population in the short term but resulting in continually high population growth and exacerbating the long-term problem.

 

To manage horse populations without periodic removals, widespread and consistent application of fertility control would be required, the committee determined.  Three methods in particular — porcine zona pellucida (PZP) and GonaCon™ for mares and chemical vasectomy for stallions — were identified as effective approaches.

 

“The committee recommended these approaches based on the evidence of their efficacy with other populations, notably the horses on Assateague Island, but cautioned that scaling up use of these methods to the larger and more disseminated horse populations in the western U.S. will be challenging,” said Guy Palmer, a veterinarian with Washington State University and chair of the study committee.

 

The committee also strongly recommended that BLM improve and standardize its methodology to estimate population size, stressing the importance of accurate counts as the basis for all management strategies.  A large body of scientific literature suggests that the proportion of animals missed in current surveys ranges from 10 percent to 50 percent.

 

Additionally, an examination of the genetics and health of population groups as well as of the range lands they occupy can be used to assure that both the animal populations and the ecosystem are being appropriately managed.  Developing an iterative process whereby public participants could engage with BLM personnel scientists on data gathering and assessment would increase the transparency, quality, and acceptance of BLM’s decision-making process.

 

The study was sponsored by the U.S. Bureau of Land Management.  The National Academy of Sciences, National Academy of Engineering, Institute of Medicine, and National Research Council make up the National Academies.  They are private, nonprofit institutions that provide science, technology, and health policy advice under a congressional charter.  Panel members, who serve pro bono as volunteers, are chosen by the Academies for each study based on their expertise and experience and must satisfy the Academies’ conflict-of-interest standards.  The resulting consensus reports undergo external peer review before completion.  A committee roster follows.

California wild horse range survey ~ after the Twin Peaks fire

Twin Peaks Post Fire Survey

May 18th and 19th 2013

tpopening

Twin Peaks Wild Horse and Burro Herd Management Area

Summary:

Three experienced wildlife observers with binoculars: Jesica Johnston, Carrisa Johnston, and Kathy Gregg

91 miles traveled in 11 hours – we drove slowly with many stops to look for animals

1 horse and 8 burros found

Vegetation in burn area in very good condition with many wild flowers, low grasses, a lot of cheat grass and what appears to be some Russian/Siberian crested wheatgrass (non-native).

Many juniper trees burned beyond survival but many were not burned or will survive the fire damage.  Sage areas clearly show the patchwork pattern of the fire, with many areas completely unburned within the Rush Fire perimeter.

Saw some bitterbrush drill seeding along Rye Patch Road.  Very little black burned grass noticeable now compared with last fall immediately following the Rush fire (see Rush fire report http://protectmustangs.org/?p=2729 ) and now most of the burned area is covered with spring vegetative growth.

Most notable was the lack of any animal trailing that can usually be seen and would have been very obvious with the new carpet of forage – believe this is because #1 no livestock on the public land and #2 very few wild horses and burros left on the Twin Peaks Herd Management Area. Also noticeable was the lack of horse and burro tracks and manure on the HMA.

Other animals observed: one coyote, two golden eagles, vultures, crows/ravens, two rabbits, birds, ducks and geese at Horne Ranch reservoir, 2 deer, ~ 20 antelope, two curlew, small fish in the Robbers Roost pond and some burrowing ground squirrels and pika.

Unless otherwise noted, all photographs were taken by Jesica Johnston and Carrisa Johnston.

[side note: BLM Litchfield Wild horses and burros facility approx. 200-300 animals maximum] Saturday 5/18/2013

Smoke Creek Road

42 miles on HMA – 4 hours

Very few signs of any Wild horses and burros in this area (trailing/tracks/manure)

1 adult brown burro 8 miles east of Hwy 395 and 1 adult dark brown burro 15 miles east of Hwy 395

    Wild Burro- Smoke Creek Road

Wild Burro- Smoke Creek Road

Turned around at Smoke Creek Ranch owned by Bright-Holland Corporation – gate locked with no trespassing signs and 150+ cattle visible and lush green fields all fenced off.

Rye Patch Road

10 miles on HMA – 2 hours

One set of fresh horse tracks on road and few manure piles but not stud pile (mare or only one horse?)  In the past (pre-fire) numerous manure piles and eight horses seen in this area.

We saw one old wild horse stud pile at Spanish Springs trough – new looking barbed wire strewn in pathway (very dangerous for any animal – we moved it)  No recent signs of horse.

Horne Ranch Road

26 miles approximately half in twin Peaks – 2 hours at dusk

Sunday 5/19/2013

Shinn Ranch Road

13 miles– 3 hours

6 Burros (5 adults and 1 yearling) north side of road about ¼ mile east of Highway 395

Conclusion

In our two days of observation we saw very few signs of any wild horses or burros and only saw one dark horse about a mile south of Shinn Ranch Road about 4 miles in from Hwy 395 – it was far off but 99% sure it was a horse in the far canyon and the only wild horse we saw on this trip.

La chasse aux mustangs ~ Hunting mustangs (Twin Peaks 2010)

 

La chasse aux mustangs

Chaque année, les autorités du Nevada, aux Etats-Unis, organisent de gigantesques captures de mustangs, ces chevaux symboles du Far West. Une fois capturés, ils sont vaccinés, castrés et envoyés dans un autre Etat. Mais pour les écologistes, se cache un autre objectif : l’exploitation du sol riche en gaz naturel.

 

Hunting mustangs

Each year, Nevada authorities, in the United States, organize gigantic roundups of mustangs, the symbolic horses of the Wild West. Once captured, they are vaccinated, castrated and sent to another state, But for ecologists, another objective is hidden: exploitation of land rich in natural gas.

Scientists find ancient horse fossils

The underside of a skull, showing palate and teeth, of Equus scotti is seen in this photo provided by the San Bernardino County Museum. The remains of the Ice Age horse were found for the first time at Tule Springs in Nevada.

Cross-posted from the Press Enterprise

San Bernardino County Museum scientists excavating an Ice Age mammoth skeleton from the Tule Springs area north of Las Vegas have found a skull and lower jaw of an ancient horse never before reported at the site or in Nevada.

Horses are not uncommon in the Tule Springs fossil record, but not Equus scotti, a large horse common in much of western North America during the Pleistocene Epoch, or Ice Age.

Las Vegas-area volunteers were instrumental in the discovery.

“Our research funding from the Bureau of Land Management includes a strong public outreach component,” said Kathleen Springer, the museum’s senior curator of geological sciences and lead scientist for the research program in the upper Las Vegas Wash. “Because of this, we set up Nevada’s first paleontology-based site stewardship program, getting local citizens involved in our research. And now it’s paid off — in a big way.”

Springer discovered the fossil site in 2003, during survey conducted by museum scientists and funded by the Las Vegas district office of the Bureau of Land Management. The original find — a tusk and tooth of a mammoth just peeking out at the surface — suggested that multiple parts of the skeleton might be present.

In 2012, Springer’s mammoth site was selected for excavation as part of the BLM’s celebration of 50 years of science at Tule Springs. The presence of multiple bones made it ideal for excavation by site stewards working with museum paleontologists.

Brushing through desert sediments at the surface quickly revealed fragments of horse teeth mixed in with the mammoth fossils. Careful digging teased out more horse teeth, then both sides of the lower jaw, and finally, the skull.

The new finds preserve anatomical features never before seen in any horses from Tule Springs, making firm identifications possible for the first time. The site is nearly 12,000 years old, making the fossils among the youngest records of Equus scotti anywhere in North America.

The discovery is forcing scientists to revise their understanding of horse evolution and extinction at the end of the Ice Ages.

Horse fossils are fairly abundant from Tule Springs and the upper Las Vegas Wash, said Eric Scott, the museum’s curator of paleontology. His studies have revealed that three species of horse lived in the area during the Pleistocene Epoch.

But none of the earlier remains discovered there were sufficiently complete to make firm species identifications possible.

“There have been some species names suggested here and there, but nothing really concrete,” Scott said. “It’s a long-running joke with our team in Vegas that every time a new site is excavated, I plead for them to find a horse I can name.”

With identifiable horse fossils so scarce, paleontologists have had to make inferences about what horse species were present around Tule Springs. Other scientists proposed that the large horse found at the Rancho La Brea tar pits in Southern California also lived throughout the Mojave Desert and the Southwest.

“We now think that’s erroneous,” Scott said. “Our new horse from Vegas has a different anatomy from the big La Brea horse. It looks more like large Ice Age horses from northern Nevada that were living at about the same time.”

The new discovery shows that Equus scotti survived in southern Nevada until the end of the Pleistocene, which was not previously known. In Southern California, the species was replaced in the later Ice Ages by an anatomically distinct form.

“That’s likely either a pulse of evolution — a speciation event — or else the immigration of a different species northwards into California from Mexico,” Scott said. “Either way, we can now clarify the timing and geographic extent of this episode, and the relationships of these two species, in a very exciting way. And it means we had as many as four horse species living in the American southwest at the end of the Ice Ages. Compared to horses today, that’s quite a lot of species.”

Springer said the find emphasizes that “even after decades of work there’s still a lot for us to learn about the Ice Ages at Tule Springs.”

The fossils are under study at the San Bernardino County Museum.

Saved from probable slaughter ~ wild youngsters are gentled and playing

 

We prefer for wild horses to remain wild and free but now there are 50,000 wild horses in government holding who are at risk of going to slaughter if the BLM’s Advisory Board members get their way. We have adopted Blondie and Tibet because as yearlings, they had already accrued 2-Strikes and were facing a dangerous 3rd. We stepped in to save them from being sold for $10 a head by the truckload.
