Take Action: Save 6 wild horse herds BLM wants to wipe out!

PM Craig Downer by Rona Aguilar

Wild horse expert sounds alarm

As the new Director of Ecology and Conservation at Protect Mustangs and a concerned Carson Valley resident, I attended the Bureau of Land Management’s (BLM) “Carson City District Draft Resource Management Plan (RMP) / Environmental Impact Statement (EIS)” meeting at the Spark’s Nugget hotel casino on Tuesday, January 13, from 5 to 7 pm.

I spoke with several BLM officials including John Axtell, the Wild Horse and Burro Specialist for this district, and Leon Thomas, Field Manager for the Sierra Front Field Office. I voiced my concerns that stakeholders who previously gave much input for increased numbers and resources in regard to wild horses were being ignored in the Draft Resource Management Plan.

I heard the overview explanation of the document by Colleen Sievers, RMP Project Lead, and instructions for reviewing it. I had given earlier input during the 2012 Scoping meetings in Carson City, along with many other pro-wild horse stakeholders.

It’s important to note there are two new wilderness designations that have just been passed by Congress for this area: Pine Forest and Wovoka Wilderness Areas.

Wild horses need you more than ever to stand up for them and here’s why:

There are five alternatives presented in the RMP document, one of which is No Action, or status quo, that will include improvements for Sage Grouse survival, but little else. Another is for maximizing resource exploitation that would be disaster for many natural values upon which the long term survival of life depends. Another (Alternative C) is for maximizing conservation of nature, and another is for bringing a so-called balance of these (Alternative E). This is the preferred alternative although it does not allocate enough land, water and forage for native wild horses who are needed to reduce wildfires, restore balance to the ecosystem, and reverse desertification on public land.

The Conservation Alternative would greatly reduce livestock grazing and expand wilderness designations but pro-wild horse stakeholders and native wild horses themselves appear to have been ignored. Wild horses should be regarded as native restorers of these natural ecosystems, but in the BLM’s Draft RMP there are serious errors which imply that they are non-native invasive pests with no value to the ecosystem. This, of course, is false.

In my preliminary view, and pending a more thorough analysis of this document, it’s  outrageous to see that federal officials appear to have completely neglected the wishes of stakeholders favoring wild horses. They unfairly sided with wild horse enemies to zero out herd management areas (HMAs). The BLM’s preferred alternative are plans to zero out six wild horse “herd management areas,” (HMA’s) rendering them “herd areas.” This is a twisting of language by which the original designation of a “herd area” as an area for wild populations of wild horses/burros in perpetuity, now according to BLM means an area where the wild horses/burros have been eliminated, or “zeroed out.”

John Axtell told me that there was not enough forage or water in these areas and that their numbers were too low. However, he conveniently failed to mention how cattle and sheep have been given the great majority of forage allocations in these same areas, or how the BLM has intentionally failed to exercise the wild horses and burros’ Implied Federal Water Rights that come with any major federal act of Congress in order to secure their basic survival requirements.

The areas that the BLM appears to be planning to zero out in the preferred alternative includes some HMA’s north of Reno such as Granite Peak and Flannigan that have been assigned truly ridiculous, low appropriate management levels (AML)—plus or minus 20 or so horses.

The minimum number for a genetically viable herd is 2,500 wild horses, according to the IUCN Species Survival Commission Equid Specialist Group and these levels are even a far cry from the suspect 150 individuals that BLM documents often cite as being genetically viable for a population.

BLM also wants to eliminate the historic Wassuk wild horse herd in the Wassuk HMA just north of Mt. Grant–where Axtell told me about 125 wild horses still survive.

Axtell claimed there was not enough forage for the horses here. I can’t believe this. I have repeatedly visited this wonderful spirited herd of Spanish-type mustangs and over many decades.

Nevadan biologist and teacher Steven Pelligrini studied the Wassuk herd for his Master’s Degree in biology at the University of Nevada-Reno. His thesis was presented to the public and to the Congress in support of the passage of the Wild Free-Roaming Horses and Burros Act of 1971, when he went to testify together with Wild Horse Annie and his professor Dr. John Pontrelli of UNR.

The Carson City BLM’s RMP is targeting our wild horses for removal yet it is mandated to protect them. There exists large-scale public support for them both among the local public, nationally and internationally.

We must stand up and fight for the Wassuk wild horses and for the other venerable wild horse herds that are being dishonestly used as scapegoats for abuses attributable to uncaring people.

I noticed that at the meeting leaders of the Toiyabe Sierra Club and long time wild horse enemies, were present, and engaged with the BLM wild horse specialists and other officials. It appears they have been working to undermine the wild horse presence on public lands for many years, and I am very disturbed about this.

In the “Toiyabe Trails” publication that goes out to many thousands as a free quarterly publication, their President, Tina Nappe seems to be given carte blanche to badmouth wild horses, while those who used to be afforded the opportunity to reply, such as myself, no longer are given this basic right, even in the form of a short letter to the editor.

In spite of the horrible news in the RMP, I was urged to make a strong statement concerning my reasons against the proposed “zeroings out”. These would include how the wild horses are not getting fair grazing allocations compared to livestock in their legal areas, failure to develop or fend for watering sources for the animals and illegal fencing prohibiting their “free-roaming” lifestyle, an inherent part of the Wild Free-Roaming Horses and Burros Act.

Protect Mustangs is calling all wild horse supporters to speak out strongly in an informed and intelligent manner, for the wild horses and burros of the Carson City BLM District. This RMP/EIS revision will govern land use policy for the next 15-20 years and we must not allow it to be a death sentence for the wild horses and burros, which it largely appears to be.

This is the public’s chance to improve the treatment of the wild horses and burros, and we cannot allow another act of subterfuge.

The proposal can be viewed online at http://on.doi.gov/1uYBNGT and more information can be found here: http://www.blm.gov/nv/st/en/fo/carson_city_field.html

Here are some talking points:

1.) Both horse and burro evolution originate and have immense multi-million year duration in North America.

2.) As post-gastric digesters, different from ruminant digesters, the equids truly restore balance to the North American ecosystem. There is a lopsided preponderance of ruminants today, encouraged by established rancher, hunter, and other linked interests.

3.) Natural predators must not continue to be persecuted and eliminated, such as puma and wolf, natural predators of the wild equids.

4.) PZP and other tamperings with basic biology and social structure of wild horses and burros is contrary to the “minimum feasible” management tenet of the WFHBA as stated in Section 3 a. See my 19 points of law on pages xi to xiii of The Wild Horse Conspiracy. See sections on PZP  in the Index as well

5.) Also look up “Pine Nut wild horse herd area” in the Index of my book for more specific information http://www.amazon.com/Wild-Horse-Conspiracy-Craig-Downer/dp/1461068983

Craig Downer speaks out against proposed roundup and PZP drugging

PM Craig Downer by Rona Aguilar

Statement by Craig C. Downer, Wildlife Ecologist and author of The Wild Horse Conspiracy (2014) concerning the BLM plans for the Pine Nut Herd Management Area (HMA) wild horse population recently announced by the Carson City BLM District Office.

December 24, 2014

Yesterday I received the Carson City BLM’s BLM Nevada News announcement of Dec. 19, 2014, from Lisa Ross, the Public Relations official. In this, the Sierra Front Field Office announced its Decision to round up 332 wild horses and permanently remove 200 of these, while releasing 132 back into the range but only after injecting the mares, estimated at 66, with 22-month Porcine Zona Pellucida (PZP-22), an immunocontraceptive vaccine whose long-term effects on the well-being of the wild horses is highly questionable.

The claim by these BLM officials is that there is an “overpopulation” of wild horses in the Pine Nuts, in other words, “excess” wild horses and that these animals are damaging the ecosystem, degrading sage-grouse habitat and reducing native grass plants. No mention, however is made of the fact that cattle and sheep grazing pressure on the grasses and other forage species is several times that of the wild horses here. Nor is any mention made of the many positive contributions the wild horses make to bolster the ecosystem as non-ruminant, post gastric digesters who complement the ruminant grazers.

I visit the Pine Nut Range frequently and am not at all convinced of the terse and perfunctory claims made in the BLM’s recent announcement. What I have observed in the Pine Nut Range is actually an under-population of wild horses who are in the process of filling their ecological niche, but are no where near filling their niche.

The arguments for the wild horse “gather” presented by the BLM are contrived and based on their desire to justify the continuing monopolization by livestock grazing permittees, mainly, but also the hunters and the Nevada Department of Wildlife, as well as other exploiters of this beautiful mountain range and its ecosystem. The claim that the wild horses are affecting the Sage-Grouse leks are highly suspect, as I have seen wonderful harmony between the wild horses and the Sage-Grouse. This issue, I feel, is being used conveniently to avoid reducing livestock. How easy to simply blame the deterioration on the wild horses, but how dishonest!

The so called Appropriate Management Level that the BLM has set for this vast range (at least 30 miles long and in places 15 miles wide) of 119 to 179 individuals is a gross injustice to the wild horses and to the many public citizens of Nevada and elsewhere. We greatly appreciate this historic herd and wish to observe a full and exuberant population of mustangs here, not an overly reduced, mere token number that is not even at a genetically viable level, and that is not permitted to adapt naturally and harmoniously to this rich ecosystem.

From observations I have gathered, the PZP vaccine will disrupt normal social interactions and cause much frustration and dysfunction among the members of this herd. There is much cover up concerning this drug and the problems for the wild horses are not being fully revealed by those promoting it, including wild horse supporters who are being manipulated into supporting PZP but relinquishing their protest of the unfair AML and the monopolization of the grazing resource by livestock interests. In doing so, they are abandoning the true intent of the WFHBA and the long-term well being of this mustang herd in the wild by going along with their semi-domestication!

To me what is happening in the Pine Nuts and with its wild horses is another “quick drug fix” the likes of which so much of modern, technologically oriented society is wont to adopt when confronted with “problems”. In other words, rather than making the needed sacrifices to share the land and freedom with the beautiful wild horses, thus allowing them to realize a truly long-term viable population in this range, true to the pure intent of the Wild Free-Roaming Horses and Burros Act of 1971 (WFHBA that was unanimously passed and remains very popular among the General Public), our officials have chosen to shirk their legal duty and “do a number” on these animals and their public supporters.

The figure of 2,500 is the number of individual horses recommended for the viability of a wild population by the IUCN Species Survival Commission Equid Specialist Group. So why is this being ignored and such cripplingly low AMLs being adopted? It is clear to me that the wild horse enemies are getting their way almost 100% and that like overly spoiled juveniles these ranchers, hunters, etc., throw a tantrum every time they are asked to share.

The Pine Nut herd is being over managed, or reduced, to a dysfunctional level and the sound tenets of Reserve Design for a thousand or more wild horses that would allow for naturally self-stabilizing and ecologically harmonious populations is being ignored by the authorities (though I have presented it to them on numerous occasions including to their RAC and National Advisory boards. Though their heart seems not to be attuned to the true and pure intent of the WFHBA, the good news is that this deplorable situation can change with the reawakening of a noble resolve to curb livestock and other overweening monopolies and to restore the Pine Nut mustangs to a much fairer and more viable population level.

I call upon BLM authorities to discontinue their insidious disinformation campaign that ignores the positive contributions that wild horses, as returned North American natives, make to the ecosystem (soils building, seed dispersal, fire prevention, etc.). From the Secretary of Interior, to the BLM and US Forest Service heads, to the Wild Horse and Burro program directors on down, there is an urgent need to “come clean,” to “own up,” and to rectify and “make up” for all the past injustices that have been committed with the aim of either crippling or eliminating America’s last wild horses. These animals are deeply rooted in America, far more deeply than most people seem to realize. They are an ancient and long-standing presence dating back millions of years, and they are true healers of the land and the life that dwells thereon. I have come to realize this so fully after a lifetime of wild horse observation and meditation. The challenge of restoring the herds and of learning to share the land and freedom with the horses, likewise their cousins the burros, is a critically important one, one linked to all of the other critical challenges facing our human kind today. To ignore or make light of this challenge is not right. IN the spirit of Christmas, the Festival of Lights, or whatever traditions one celebrates during these Holy Days of renewal and recommitment, I call upon everyone to honor the place of the wild horse upon the land that is their ancient home, knowing we will be blessed for so doing and even in ways we at present can scarce imagine.

PZP advocates put wild horses at risk of sterilization after roundup

Stop the Roundups!

Protect Mustangs calls for a freeze on roundups for scientific reevaluation

Tonopah, NV (October 31, 2014)–The Battle Mountain District, Tonopah Field Office is rounding up about 120 wild horses from within the Reveille Allotment and Herd Management Area (HMA) located approximately 50 miles east of Tonopah, NV to remove alleged excess wild horses on 600,000 acres of public land.

“The BLM is wiping out America’s wild horses and taxpayers are paying for the abuse,” states Anne Novak, executive director of Protect Mustangs. “We need to stop the roundups and protect our native wild horses.”

The roundup will stampede native wild horse families by helicopter over a fragile ecosystem and possible sage grouse habitat in the Great Basin Desert. Often wild horses are injured and die in roundups. The treacherous roundup is paid for with tax dollars, and began October 30, 2014. Most herds need to be rounded up before given PZP.

After the roundup, approximately 70 wild horses will be permanently removed, 60 wild horses will be sent to holding facilities in Ridgecrest, California and about 10 horses will be offered for adoption after the roundup in Tonopah, NV on November 8. The remaining 50 wild horses will be released back into the HMA for a post roundup population of 98 wild horses, putting the survivors at risk. The minimum number for genetic variability is 150 wild horses.

Often the BLM returns wild horses with conformation defects to the range, instead of placing them in adoptive homes or long-term holding where they will not breed. Apparently the agency doesn’t realize that by returning wild horses with defects they will ruin the breeding pool. The BLM claims mares selected to maintain herd characteristics will be released back to the HMA. The public must watchdog the agency to ensure wild horses with defects are pulled from the breeding pool and rehomed. Euthanizing them is not an option supported by the American public.

The informed public is outraged over an EPA approved restricted use pesticide called PZP, made from pigs ovaries, to be used on native wild horses. PZP advocates campaign rigorously to treat mares with the Porcine Zona Pellucidae (PZP-22) in order to temporarily sterilize mares. PZP advocates hail the use of PZP in spite of the fact that wild horses are underpopulated on millions of acres of public land.

Experimental research on ovary damage in mares given the immunocontraceptive PZP is used to hone the drug for eventual human use. This could be where the “follow the money” piece fits in. Wild horse advocates are furious America’s herds are being used as lab rats. Science has proven the drug sterilizes wild horses after multiple use. PZP advocates are pushing for BLM to manage wild horses “in the wild” using these risky drugs.

The devastation of wild horses in the Reveille Allotment appears to be subject to a 1987 District Court Order and two orders issued by the Interior Board of Land Appeals (IBLA) in 2001 and 2002, requiring BLM conduct an annual inventory of wild horses in the Reveille Allotment and initiate a roundup to remove alleged excess native horses from the Allotment when the inventory shows that population numbers exceed the out of date Appropriate Management Level (AML) of 138 horses.

Current AML does not represent healthy herd populations and lacks scientific merit. AML must be updated to ensure healthy herds remain on public land. The herd census must never fall below 150 wild horses to maintain genetic variability.

The current estimated population, based on previous inventory flights is 168 wild horses, according to BLM. This is the low end of the genetic viability scale. The orders need to be challenged based on scientific reevaluation of wild horses benefiting the ecosystem as a native species, livestock causing range damage and the minimum number of wild horses needed for genetic variability.

“We must ensure native wild horses can survive upcoming environmental changes,” states Anne Novak, executive director of Protect Mustangs. “The minimum population for a genetically variable herd is 150. Why are PZP advocates and the BLM allowing wild horse herds to fall below safe numbers?”

According to a press release from National Academy of Sciences (NAS) released June 5, 2013, “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 NAS report states there is “no evidence” of overpopulation. Only tobacco science and spin backs up BLM’s population claim to justify roundups and fertility control/sterilizations. PZP advocates lobbied NAS to have fertility control recommended even though the herds are underpopulated.

Roundup activities within the Reveille HMA were analyzed in the 2010 Reveille HMA Wild Horse Gather Plan and Environmental Assessment (EA) and the 2014 Reveille Wild Horse Gather Determination of NEPA Adequacy (DNA). The EA, DNA, and Decision Record can be accessed on the Reveille Wild Horse Gather website: http://on.doi.gov/10qLBlh.

Members of the public are encouraged to witness the helicopter stampede and document America’s icons losing their freedom to spread awareness that cruel roundups must stop. Observation protocols and visitor information are available at http://on.doi.gov/1xAMeTp. The BLM will post updates, photos and other information about the roundup on the Reveille website and on the hotline at 775-861-6700 throughout the course of the roundup.

The BLM is wiping out wild horses for the extractive industry and New Energy Frontier in the West. The agency manages more than 245 million acres of public land, the most of any Federal agency. This land, known as the National System of Public Lands, is primarily located in 12 Western states, including Alaska. The BLM also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM focuses on their mandate of multiple-use and sustained yield. In Fiscal Year 2013, the BLM generated $4.7 billion in receipts from public lands.

BLM’s roundups disturb the thriving natural ecological balance by disturbing habitat dynamics. This crime against nature causes abnormally high birthrate and puts native wild horses at risk of inbreeding.

“We are calling for an immediate freeze on roundups and removals for scientific reevaluation,” states Novak. “Right now native wild horses are at risk of being ruined by bad policy.”

Protect Mustangs is a nonprofit organization dedicated to the conservation of native and wild horses. The group is against using PZP in the wild. Today most wild herds are threatened with low numbers and a lack of genetic variability. Using PZP in a sanctuary setting where acreage is limited is a different situation. Wild horses must not be managed in the wild as if they were a zoo exhibit.

The Horse and Burro as Positively Contributing Returned Natives in North America

 

Craig Downer

Esteemed wildlife biologist and Protect Mustangs’ Advisory Board member, Craig Downer, has published a paper offering Reserve Design strategy for wild horses and burros.

From the American Journal of Life Sciences:

Since the Wild Free-Roaming Horses and Burros Act of 1971, debate has raged over whether horses and burros are restored North American natives. Fossil, genetic and archeological evidence supports these species as native. Also, objective evaluations of their respective ecological niches and the mutual symbioses of post-gastric digesting, semi-nomadic equids support wild horses and burros as restorers of certain extensive North American ecosystems. A Reserve Design strategy is proposed to establish naturally self-stabilizing equine populations that are allowed to harmoniously adapt over generations within their bounded and complete habitats. These populations should meet rigid standards for viability based on IUCN SSC assessments (2,500 individuals). Basic requirements are described for successful Reserve Design including viable habitat as well as specific regions of North America where this could be implemented.
