No excess wild horses in the Pryors

Posted on June 10, 2015 by Protect Mustangs

PZP is a risky pesticide. Will it ruin the treasured herd?

By Marybeth Devlin

The issue underpinning the use of PZP and the continuing cycle of removals of wild horses from the Pryor Mountain Wild Horse Range is: Whether there are excess wild horses. No, there aren’t. BLM creates the illusion of an overpopulation by administratively setting the maximum herd-size below minimum-viable population. The International Union for the Conservation of Nature determined that, if a herd were managed carefully per a stud-book, it could sustain itself genetically at a minimum of 500 individuals. Compare that number to BLM’s maximum: 120.

In fact, according to the latest genetic analysis, the Pryor Mountain herd is evidencing “a general trend for a decline in variations levels of the herd.” The recommendation was to “increase population size.” Yet, BLM stubbornly insists on its own failed approach of artificially limiting herd-size, declaring that it disagrees with the scientific “interpretation.”

But can the range accommodate more horses? Yes. By way of comparison, BLM allots 38 acres per cow or calf when setting the stocking-rate for livestock grazing. Thus, the 33,187 acres that compose the Pryor Mountain habitat can support 500 to 873 horses. When the WHR is restored to its original configuration, 44,920 acres, the high-bound can be increased to 1,182.

As for PZP, numerous independent studies have disproved the old theory that PZP merely blocks sperm attachment. In fact, PZP’s mechanism of action is to alter ovarian function, causing inflammation of the ovaries and cyst formation. PZP provokes an auto-immune response, wherein the pig-ovary-derived PZP antibodies attack the mares’ ovaries, resulting in dystrophy of those reproductive organs. Despite being hyped as a non-hormonal contraceptive, PZP causes “markedly depressed oestrogen secretion” in mares treated for just three consecutive years. The latter finding was disclosed by Dr. Kirkpatrick himself 23 years ago. PZP-use is associated with stillbirths, altered ovarian structure and cyclicity, interference with normal ovarian function, permanent ovarian damage, prolonged breeding season, and unusually-late birthing dates. A particularly troubling finding suggests that PZP can be selective against a certain genotype in a population.

PZP is touted as reversible; however, a recent study warned that just three years of treatment, or administration of the first PZP injection before puberty, may trigger infertility in some mares. Thus, only two PZP injections could be viewed as relatively safe, but it appears that even one injection is risky. The researchers warned that inducing sterility may have unintended consequences on population dynamics by, ironically, increasing longevity while eliminating the mares’ ability to contribute genetically.

Most pertinent to the Pryor Mountain herd is a longitudinal study on three herds treated with PZP — Little Book Cliffs, McCullough Peaks, and … Pryor Mountain. The researchers found that the birthing season lasted nearly year-round: 341 days. Out-of-season births put the life of the foals and the mares at risk. That same longitudinal study found that, following suspension of PZP injections, there was a delay in the mares’ recovery of fertility that lasted 411.3 days (1.13 years) per each year of PZP treatment. Thus, mares injected for four consecutive years (per BLM’s “prescription”) would be expected to take 1,645.2 days (4.51 years) to regain reproductive capacity. If disaster were to befall the Pryor Mountain horses, even if PZP were stopped immediately, it would take years for the herd to recover, if ever.

PZP has neither stopped nor slowed the roundups. Only lack of holding space has done that. Even the Pryor Mountain herd, injected for decades with PZP, is facing removals again this summer (per the usual three-year cycle) in addition to an intensified PZP “prescription” to be administered per an “equal opportunity program” eerily similar to Communist-China’s one-child policy. What’s ironic is that, for all the interference, BLM has achieved basically the same — or worse — record as has been attained the International Society for the Protection of Mustangs and Burros. ISPMB complies with the “hands-off” minimum-feasible management approach stipulated by the Wild and Free-Roaming Horses and Burros Act. ISPMB’s two wild herds grew 8.73 and 5.08 percent, respectively, without PZP and without removals. Pryor Mountain’s most recent report — reflecting management with PZP and with removals — grew by 8.26 percent.

BLM needs to get out of the way of Nature. Let the Pryor Mountain herd find its own appropriate population level.

Debate rages over the use of birth control on wild horses & burros

Posted on March 9, 2015 by Protect Mustangs

The debate about the use of birth control on wild horses and burros is coming to the forefront.
The question looms why should current population numbers be suppressed with birth control when there are only half the number present now than in 1971 when they were first protected.

The 1971 law is explicit in saying the animals were fast disappearing from the American scene and that there should be minimal management of the animals. When population counts were done in 1974, there were nearly 50,000 animals based on a counting system that drastically undercounted the animals by today’s standards. Today we are lucky to have 30,000 animals.

The National Academy of Sciences (NAS), whose report was released in 2013, noted that BLM‘s management practices are facilitating high rates of population growth by holding horse populations below levels affected by food limits. “If population density were to increase to the point that there was not enough forage available, it could result in fewer pregnancies and lower young-to-female ratios and survival rates,” according to NAS.

ISPMB’s horses have held their own even with good feed conditions. An example is the Gila herd that began with 31 animals and 14 years later, they have crested to 100 animals. If these were BLM horses, this year we should have 248 horses. ISPMB’s studies have shown that the stability of the harems has led to reduced growth rates. This means that the harems should not be disrupted by removals, separating stallions from mares. We know that once that happens, the stallions lose their mares to younger stallions being released back onto the herd areas.

Bottom line is that roundups whether for removal or birth control injections causes the same problem – increase in fertility rates due to the disruption of the harems. The future for best management practices by the BLM should be in bait trapping when removals are necessary, keeping the harems intact. Even though it is more time intensive, the overall costs in removals and warehousing animals would be and would have been drastically reduced.

The argument against the use of birth control continues for the following reasons: animals would have to be treated yearly which means that the harems would be disrupted constantly. And adding to their disruption, instead of only 50-60% of the animals gathered during a usual roundup, the majority (90%) of the herds must be gathered to implement birth control. This means that there would be almost no harem that wouldn’t be disrupted! The result again, increase in fertility rates from disruption. So combating growth rates by using contraception actually increases rates!

We know that permanent infertility can happen after five years of application of the drug to the same animal. And we don’t know the far reaching effects of the long-term use of the drug on modeling behaviors for the animals or any side affects if foals were to be born to mares that have received long-term treatments.

The final and most important argument against the use of birth control is that we as human beings must select who breeds and who does not breed. In the domestic horse industry, we have failed miserably as breeders of horses. One can easily point to the Quarter Horse Industry where the average age of soundness is seven years, the age of a horse just entering its prime of life. That means at age 8 and older, horses are breaking down due to having too much weight on legs that can’t support the weight. Nature has provided the best breeding program available for wild horses and that being “survival of the fittest.” One just has to look at the legs of a wild horse compared to any other breed of horse. And we know they are generally healthier and happier.

If BLM were to manage wild horses by not disturbing them, they would do more to hold down birth rates in the long run. Removal of “excess” wild horses/burros should only be done by bait trapping to ensure that wild horses and burros truly remain wild. Sadly, instead of feasible minimal management, we now are at maximal intrusive management.

(Note: ISPMB does not discourage the use of birth control in sanctuary settings where horses live together in families and will never breed again.)

RE: Pryor Mountain Wild Horse Range Fertility Control Preliminary Environmental
Assessment Tiered to the Pryor Mountain Wild Horse Range Environmental Assessment and Herd Management Area Plan May 2009 EA DOI-BLM-MT-0010-2011-0004-EA

Dear Jared Bybee:

Background

I appreciate the opportunity to submit comments on the Pryor Mountain Wild Horse Range
Fertility Control Preliminary Environmental Assessment Tiered to the Pryor Mountain Wild
Horse Range Environmental Assessment and Herd Management Area Plan May 2009 EA DOI-BLM-MT-0010-2011-0004-EA. My background is in equine reproductive immunology and wildlife conservation. I applaud the Billings Field Office of the Bureau of Land Management (BLM) for a thoughtful approach to this issue. Cover letter 4700 (010.JB) dated November 2010 and signed by James M. Sparks, Field Manager states that the BLM would consider comments and revision to the EA or unsigned FONSI as appropriate. I urge a “no action alternative” as outlined on page 7 and 8 of the EA. This request is based on two pieces of new scientific evidence about effects of current immuno-contraception use.

Porcine Zona Pellucida (PZP) Contraception

The proposed action as stated on page 7 of this EA would exempt “mares ages 5-10 unless they have produced foals, or are part of a large bloodline.” This is reminiscent of the approach taken with the Assateague Island wild horse population. It is a compromise approach to this issue, in comparison to placing all mares on PZP. However a recent study shows that mitochondrial DNA diversity is low in the Assateague Island horse herd (Eggert et al. 2010). Since mitochondrial DNA is inherited from the mother (mare), this is evidence that female inherited genetics on Assateague Island wild horses is under represented. It is imperative that this be assessed before rolling out a similar management plan for the Pryor Mountain wild horses.

There is a recent Princeton University study on PZP effects. Consecutive PZP applications, analogous to the proposed action plan in this EA, showed that mares gave birth later in the season, and were cycling into the fall months (Nunez et al. 2010). In a state like Montana where freezing temperatures are found in the fall, this can have serious and long term effects on foal survivorship.

I must include a statement on long term consecutive use of PZP. Any form of PZP contraception is not completely reversible in mares depending on the length of use of PZP. Contraception can only be reversed when the antibody titer decreases to 50-60% of the positive reference sera (Liu et al. 2005). Mares treated for 7 consecutive years do not return to viable fertility (Kirkpatrick and Turner 2002; Kirkpatrick et al. 2009). The issue of reversible contraception is very important to be able to maintain wild equines in the United States. Long term treatment with PZP has inherent negative potential for this herd.

I am requesting a new look at the proposed fertility control action for the Pryor Mountain wild horses.

Sincerely,

Bogus Science and Profiteering Stampeding Their Way into Wild Horse Country

Posted on November 4, 2014 by Protect Mustangs

A Review of Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward (2013)

by Jaime Jackson, AANHCP Executive Director

I’ve reviewed the entire 300+ page National Academy of Sciences report—clearly a major undertaking by all the scientists involved and a bit of a “heavy” read—including its academic findings and recommendations (“A Way Forward”) which are, in the end, woefully predictable. Thinking about it, however, the scientists who created the report really had no choice, given the limits of the Wild, Free-roaming and Burro Act itself, if we are to accept that, but to work within its boundaries and the conundrum set upon them by that law’s specious political and land management premise and somehow respond to the task put upon them by the BLM. Clearer and more honest minds might have said, “I want no part of such a nasty, skewed project.” I also gleaned the biographies of each scientist to see what kind of understanding they would bring to the table regarding horse care based on their education and training, and if they seem like “clear minded” thinkers who could think outside the box in the best interest of any horse. On that note alone, wild horses are in trouble.

Because the “limits” put upon the NAS committee by the wild horse law are what they are, and because these are basically mainstream scientists drawn out of academia, it is entirely logical that they would recommend regulating wild horse and burro populations, in their words, “with science”. But what kind of science, one might ask? Well, the fact is, it’s the same brand of science, and scien- tific minds in today’s academia, that has failed the domesticated horse. We’re talking about scientists who serve the special interests of government and its lobbyists, the agricultural and pharmaceutical industries, and so forth, that have given us drugs and feeds and management practices that cause laminitis and other metabolic breakdowns of the horse. Indeed, it is all profitable for the very community that has created this “science based” disaster for horses. I’m not just spewing words here without foundation, horses truly suffer for it, and it is this bad science and corresponding harmful equine management practices that have given birth to and fueled the internationally burgeoning NHC movement. That is a fact—and it is a fact also that these scientists, and the special interests that fund them, refuse to acknowledge NHC because what we do and advocate for gets directly to the bottom of ethics and profiteering and inbred academic close-mindedness.

The authors of this NAS report have very skillfully woven together what is genuinely good sci- ence with the bad, while ignoring other good science altogether—all to the end of supporting the bogus proposition that their brand of “science” favors a lasting solution for wild horse management. If one reads their report carefully, however, one can sense the palpable excitement and impatience behind their drug-based recommendations. For example, they urge the BLM to step up an accurate numbers count in the HMAs (which, arguably, given that agency’s past, can never be trusted) because, they suggest, the quantities of PZP and other pharmaceutical agents needed to cleanse wild horse country will surely be vastly greater than what was used in their scientifically con- taminated control study done to the Assateague ponies of the U.S. east coast (cited in their re- port). Assateague was not good science, anymore than what has happened to those horses long before the government’s study. It catered to the drug industry and the same eugenics science that the U.S. and British governments sanctioned and used against people during the greater part of the 20th century (up to the 1960s and 70s), and that was astutely “borrowed” from by Nazi Germany for its extermination campaigns to “rid the world of undesirables”.

Just as tactfully, and just as predictably, the NAS authors stated that predation behavior was not viable, ignoring Drs. Turner and Morrow’s mountain lion predations studies referenced in my books, The Natural Horse and Paddock Paradise, and which proved the viability of natural predation on wild horse herds. Of course, the reason that natural mountain lion and wolf predation won’t work, and which the NAS report fails to explain, is because BLM management practices have provided for their extermination and/or removal under welfare ranching pressure that deflects the truth of what’s happening within their grandfathered land leases born of the Taylor Grazing Act and the BLM’s inception.

I could easily go on, and on, and on, nit picking the massive tangled NAS report, but would just be wasting my time and yours with the report’s self-serving “word salad”. The fact is, there is no genuine solution in their report that respects the natural integrity of America’s wild, free- roaming horses. And there is no debating the authors of the report either, for they are completely sold out to the very special interests who have never seen value in our wild horses. In fact, it is the science community that has recently aided and abetted the government in reclassifying wild horses legally as “pests” so that the pesticide PZP can be used on them for birth control purposes. You see, the NAS report is no surprise, as its convoluted “commandments” have been systematically orchestrated and colluded with by just about everyone in sight, including—and I am sad to say—nearly every purported “wild horse protection” group and sanctuary in the United States. Many of these groups stand to “gain” from this collusion, including the HSUS that co-owns patent rights to PZP.

Tax payers can expect to pay more, not less, as they watch their wild horse herds deteriorate genetically under the government’s Nazification of the HMAs through racism-based eugenics. This is because there is profit motive at its foundation. In fact, the report cautions that “public confidence” and trust will be an important part of the “master solution”. Inundating tax payers with scientific “word salad” that few can understand, is understood. Clearly, the public does not understand the underlying issues, except what they hear in the news. From that vantage point, this does not bode well for our wild horses.

What is needed is a new vision and a new law for genuine wild horse preservation. The current law is bankrupt and offers no real protection, let alone preservation. Science, industry and the big government have joined claws and are at war with Natural Selection, because they are losing—and they know it. And, it is for this reason, that Science is now being called upon to step up the delusion that the war on nature can and will be won. Like the war on cancer, no such victory is forthcoming. But because the war is profit driven, the war is welcome. Read the NAS report with a critical eye, and you will see this. In the end, HMAs will become zoos with GMO wild horses. Like those we see in the wild horse protectionist’s “sanctuaries”: sad, pathetic parodies of real wild horses. Is this what the public envisioned when it stood behind the original wild horse protection law? Of course not. but, here today, government and science and industry (and its camp following ersatz wild horse protectionists begging for crumbs), all hand in hand, are going to exploit wild horses and unwitting taxpayers for what they can—until, at long last, nature has proven them wrong, and the deceptive game is exposed for all to see. The Assateague model, which they will cite and hold up, is a broken one. But they are counting on an uninformed public to buy into it. Those of us in the NHC movement know better and can refute it with facts by simply looking at the hooves of those horses, if not the non-adaptative environment they are squeezed into be- cause of an historical fluke. Looking through the bios of the NAS committee members, I seriously doubt that any of them would have a clue of what I’m talking about.

The Obama Administration, as much of the voting public on both sides of the aisle have come to realize, is a compromised, “sold out to big industry” travesty that is going to stand be- hind the eugenics science and land grab scheme fully intended to bilk the taxpayer and pad the pockets of profiteers who, quite frankly, don’t give a damn about wild horses. That includes Sally Jewell, Obama’s hand-picked clone of Ken Salazar to head the Department of the Interior (BLM’s overseer), who is no friend of the wild horse or any horse. She came right out of big banking and the oil industry. Check out her bio on her DOI government website. She will go right along with “big science” because that is where the money is and because, the fact is (and it is not rocket science to figure it out), it will lead to the decimation of wild horse herds. James Kleinert’s film “Wild Horses and Renegades” draws a direct line between Jewell, “wild horse pests” and their extermination, and the land grab now going on in BLM country by big industries such as BP and backed by the Obama Administration.

Let me put it in simple terms — it’s just a matter of time before they’re shoeing wild horses in the HMAs! If you don’t want that, support the AANHCP’s vision for genuine, lasting wild horse protection and taxpayer relief.

PZP advocates put wild horses at risk of sterilization after roundup

Posted on October 31, 2014 by Protect Mustangs

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.

Dangerous times for wild horses and burros

Posted on October 11, 2014 by Protect Mustangs

Dear Friends of Wild Horses and Burros,

There are several dark forces at work who want to control America’s wild horses and burros. Some want to steal them from the people so corrupt state officials can hunt and kill them or sell them to slaughter. Others want to drug them with EPA approved restricted-use pesticides such as PZP that sterilize WILD mares after multiple use. Fertility control research trials are big business. Left unchallenged, wild horses and burros will continue to be lab rats for human fertility control research. Many soulless degenerates want to slaughter wild horses for human consumption abroad. They really want to make room for energy development and subsidized grazing on public land at the expense of wildlife and especially wild horses and burros.

Be careful what you sign. Read everything carefully. Please read this petition carefully too then send it to your friends and family so the voiceless can be protected from the exploiters and the killers. If you want to know the truth behind the facade . . . follow the money.

Thank you for taking action to help America’s wild horses and burros by sharing this petition (http://www.change.org/p/defund-and-stop-the-wild-horse-burro-roundups) via email and through your social networks. Together we can shine the light on the truth to turn things around. Stop the Roundups!

Many blessings,
Anne

Native wild horses are not pests ~ Stop managing them to extinction

Posted on August 11, 2014 by Protect Mustangs

Dear Friends of Wild Horses and Burros

Protect Mustangs is a national nonprofit organization making grassroots count. Our mission is to protect and preserve native and wild horses. Besides engaging mostly in outreach and education about the wild horse crisis, we advocate for holistic land management, self-sustaining herds and reserve design. We are calling for a 10 year moratorium on roundups for the herds to recover from the roundups and for studies to form good management plans. Right now there are no accurate census counts on the range so we don’t even have a clear picture of the few wild horses left living in freedom.

Our members don’t see an overpopulation or “excess” of wild horses on public land, even if the population is over BLM’s biased appropriate management level (AML). Livestock outnumbers wild horses more than 50 to 1 on the range. Yet wild horses are always scapegoated for damage by special interest groups.

We are deeply concerned that the use of FDA approved “restricted use pesticides” such as PZP–an immunocontraceptive made from pig ovaries that people call birth control–sterilizes mares after multiple uses and should never be used on nonviable herds, those herds with less than 150 wild horses. Genetic diversity is essential for survival and using PZP surely will curtail that. There is one herd in Nevada currently being treated by wild horse advocates that seems to have less than 50 wild horses. This worried us.

Wild horses are a native species and not pests. Sadly there are factions who are treating wild horses as individuals and ignoring the herd element and other factions treating wild horses as invasive pests.

Despite decades of experimental research on wild mares, the FDA would not approve PZP as safe. Eventually the EPA approved it as a restricted use pesticide. You can see the pesticide fact sheet here: http://www.epa.gov/pesticides/chem_search/reg_actions/pending/fs_PC-176603_01-Jan-12.pdf

How can drugging mares with restricted use pesticides be honoring their freedom? Most of the time the BLM will need to round them up to dart them anyway. You can hear the BLM official speak about that here: http://www.thespectrum.com/videos/news/local/cedar-city/2014/08/06/13698391/

We are also concerned PZP and other sterilants affect behavior and that mares will be subjected to live in unnatural situations.

Ruining survival of the fittest and natural selection is our biggest concern if man chooses who breeds and how many foals are born. The herds must adapt to upcoming environmental and climate changes in order to survive, therefore genetic variability is essential at this pivotal time.

We are 100% volunteer and are working to help the wild horses without any conflict of interest as far as we can tell. We do not receive funding from influencers, corporations or organizations connected with the drug PZP, the pharmaceutical industry, Big Oil and Gas or other energy, ranching and mining sources. That’s why your donations are so important.

Our vision is to speak out for the voiceless, stop the BLM from being cruel to wild horses and work towards a solution for healthy management keeping wild horses on the range based on good science. We have a petition out for the 10 year moratorium on all roundups. Please sign and share it here: http://www.change.org/petitions/sally-jewell-urgent-grant-a-10-year-moratorium-on-wild-horse-roundups-for-recovery-and-studies

Thank you for reaching out to us. It’s important to do the research and find the answer for yourself so you can feel good about taking action to help save the last of the wild horses and burros.

We are grateful you care so deeply about saving America’s wild ones.

Many blessings,
Anne

Horse contraceptive study raises concerns

Posted on July 25, 2014 by Protect Mustangs

October 29, 2010
By Laurie Dixon
Research indicates the long-term horse contraceptive, porcine zona pellucida (PZP), extends the breeding season in wild horses, raising concerns over the social consequences of the drug on herds.

PZP, which is derived from pig eggs, is increasingly being used in wild horse herds . . .

Alarm over behavioral and physiological side effects of wild horse birth control (PZP)

MANAGEMENT OF WILD HORSES WITH PORCINE ZONA PELLUCIDA: HISTORY, CONSEQUENCES, AND FUTURE STRATEGIES

Cassandra M.V. Nuñez

Department of Ecology and Evolutionary Biology, Princeton University, Princeton, New Jersey

ABSTRACT

The advent of immunocontraception with porcine zona pellucida (PZP) has all but revolutionized wild horse management, providing a more humane method of population control than earlier strategies. Early studies on Assateague Island National Seashore have described it as an ideal form of fertility control in that it reduces the chance of conception to below 10%, can be delivered remotely, is reversible (after short-term use), lacks debilitating physiological side effects, cannot pass through the food chain, and shows minimal effects on social behaviors. However, recent research in other populations has revealed behavioral and physiological side effects of long-term PZP use. These results indicate that studies from one population may not necessarily be applicable to another, regardless of similarities in habitat and population structure. Careful study of the animals’ demography, physiology, and behavior is necessary prior to and during treatment to ensure that a) the potential effects of PZP can be assessed accurately, and b) within managerial constraints, PZP effects are ameliorated as much as is possible. Here I explain the history of PZP use in wild horses, its side effects on the horses of Shackleford Banks, North Carolina in comparison to other populations, and offer management suggestions based upon wild horse biology and behavioral ecology, which may minimize or prevent these side effects in other populations.

Moratorium on roundups needed for scientific research before sterilization

Posted on February 15, 2014 by Protect Mustangs

“Currently there is no evidence of overpopulation but the runaway train for fertility control and sterilization bashes down the tracks,” explains Anne Novak, Executive Director of Protect Mustangs. “We request a ten-year moratorium on roundups for scientific studies on population, migration and holistic land management. Science must come first.”

Panel: Sterilize wild horses to cut population

By Sean Cockerham
McClatchy Washington Bureau

Published: Thursday, Jun. 6, 2013

WASHINGTON – The federal government should do large-scale drug injections of wild horses to make them infertile, according to a highly anticipated recommendation from the National Academy of Sciences.

The report released Wednesday said the Interior Department’s strategy for wild horses is making a bad situation worse. The government has rounded up nearly 50,000 wild horses and put them in corrals and pastures.

More of America’s wild horses are now in holding facilities than estimated to be roaming the wild, in what the National Academy of Sciences called a failure to limit the animals’ fast-growing numbers.

The Interior Department’s Bureau of Land Management requested the report amid frustration and skyrocketing costs of the wild horse and burro program. The annual cost to taxpayers of the program has nearly doubled in four years to $75 million, with more than half going to costs of holding facilities.

The BLM says roundups and holding facilities are needed because swelling horse populations are too much for the wild range to sustain. Wild horse advocates say the issue is really about favoring the interests of ranchers whose cattle and sheep graze upon the public lands.

The National Academy of Sciences said a big problem is that the Bureau of Land Management doesn’t really know how many wild horses and burros there are in America, or their true impact on the rangelands. The report concluded that BLM is likely underestimating the number of wild horses in America and that their populations are growing by as much as 20 percent a year.

The independent panel of scientists that wrote the report said the agency needs a more defensible scientific backup for its decisions on wild horses, including consideration of the impact of livestock on the range.

“The science can be markedly improved,” said Guy Palmer, a Washington State University professor who led the panel.

The government’s roundups of wild horses are just making the population problem worse, according to the report. Shutting tens of thousands of horses in holding facilities means less competition for food and water on the range and more population growth, it concluded.

Leaving the horses alone to roam the range would lead to a competition among them for food and water that would meet the goal of cutting their numbers, according to the report. But “having many horses in poor condition, and having horses die of starvation on the range are not acceptable to a sizable proportion of the public,” the authors concluded.

The best alternative is a widespread use of fertility control measures, the independent scientific panel decided. They recommended chemical vasectomies for stallions and the injection of the contraceptive vaccines GonaCon and porcine zona pellucida for mares.

In contrast, Karen Sussman of the International Society for the Protection of Mustangs and Burros has been studying herds in her care for 13 years. The results show healthy social structures of wild horses control population.

ISPMB herds show that functional social structures contribute to low herd growth compared to BLM managed herds

As we complete our thirteenth year in studying the White Sands and Gila herds, two isolated herds, which live in similar habitat but represent two different horse cultures, have demonstrated much lower reproductive rates than BLM managed herds. Maintaining the “herd integrity” with a hands off management strategy (“minimal feasible management”) and no removals in 13 years has shown us that functional herds demonstrating strong social bonds and leadership of elder animals is key to the behavioral management of population growth.

ISPMB’s president, Karen Sussman, who has monitored and studied ISPMB’s four wild herds all these years explains, “We would ascertain from our data that due to BLM’s constant roundups causing the continual disruption of the very intricate social structures of the harem bands has allowed younger stallions to take over losing the mentorship of the older wiser stallions.

In simplistic terms Sussman makes the analogy that over time Harvard professors (elder wiser stallions) have been replaced by errant teenagers (younger bachelor stallions). We know that generally teenagers do not make good parents because they are children themselves.

Sussman’s observations of her two stable herds show that there is tremendous respect commanded amongst the harems. Bachelor stallions learn that respect from their natal harems. Bachelors usually don’t take their own harems until they are ten years of age. Sussman has observed that stallions mature emotionally at much slower rates than mares and at age ten they appear ready to assume the awesome responsibility of becoming a harem stallion.

Also observed in these herds is the length of time that fillies remain with their natal bands. The fillies leave when they are bred by an outside stallion at the age of four or five years. Often as first time mothers, they do quite well with their foals but foal mortality is higher than with seasoned mothers.

Sussman has also observed in her Gila herd where the harems work together for the good of the entire herd. “Seeing this cooperative effort is quite exciting,” states Sussman.

ISPMB’s third herd, the Catnips, coming from the Sheldon Wildlife Range where efforts are underway to eliminate all horses on the refuge, demonstrate exactly the reverse of the organization’s two stable herds.

The first year of their arrival (2004) their fertility rates were 30% the following first and second years. They have loose band formations and some mares are without any harem stallions. Stallions are observed breeding fillies as young as one year of age. Foal mortality is very high in this herd. Generally there is a lack of leadership and wisdom noted in the stallions as most of them were not older than ten years of age when they arrived. In 2007, a decision to use PZP on this herd, a contraceptive, was employed by ISPMB. This herd remains a very interesting herd to study over time according to Sussman. “The question is, can a dysfunctional herd become functional,” says Sussman who speculates that the Catnips emulate many of the public lands herds.

In 1992 when Sussman and her colleague, Mary Ann Simonds, served on the National Wild Horse and Burro Advisory Board, they believed that BLM’s management should change and recommended that selective removals should begin by turning back all the older and wiser animals to retain the herd wisdom. Sussman realizes that the missing ingredient was to stop the destruction of the harem bands caused by helicopter roundups where stallions are separated from their mares. “Instead, bait and water trapping, band by band, needed to be instituted immediately,” says Sussman. Had this been done for the past twenty years, we would have functionally healthy horses who have stable reproductive rates and we wouldn’t have had 52,000 wild horses in holding pastures today. BLM’s selective removal policy was to return all horses over the age of five. When the stallions and mares were released back to their herd management areas by the BLM, younger stallions under the age of ten fought for the mares and took mares from the older wiser stallions. This occurs when there is chaos happening in a herd such as roundups cause.

Sussman also believes that when roundups happen often the younger stallions aged 6-9 are ones that evade capture. This again contributes to younger stallions taking the place of older wiser stallions that remain with their mares and do not evade capture. She is advocating that the BLM carry out two studies: determining the age of fillies who are pregnant and determining age structures of stallions after removals.

Currently Sussman is developing criteria to determine whether bands are behaviorally healthy or not. This could be instituted easily in observation of public lands horses.

Taken from BLM’s website: “Because of federal protection and a lack of natural predators, wild horse and burro herds can double in size about every four years.”

White Sands Herd Growth: 1999-2013 – 165 animals.

BLM’s assertion herds double every four years means there should be 980 horses or more than five times the growth of ISPMB’s White Sands herd.

Gila Herd Growth:1999-2013- 100 animals.

BLM’s assertion herds double every four years means there should be 434 horses or nearly four times the growth of ISPMB’s Gila herd.

Sussman says that BLM’s assertion as to why horse herds double every four years is incorrect. The two reasons given are federal protection of wild horse herds and lack of natural predators. ISPMB herds are also protected and also have no natural predators, but they do not reproduce exponentially. She adds that exponential wild horse population growth on BLM lands must have another cause, and the most likely cause is lack of management and understanding of wild horses as wildlife species. Instead BLM manages horses like livestock. “According to the Wild Horse and Burro Act of 1971, all management of wild horse populations was to be at the ‘minimal feasible level’,” Sussman says. “When the BLM’s heavy-handed disruption and destruction of wild horse social structures is the chief contributing factor in creating population growth five times greater than normal, than the BLM interference can hardly be at a ‘minimal feasible level.’”

Sussman concludes that ISPMB herds are given the greatest opportunity for survival, compared to the BLM’s herds which are not monitored throughout the year. “One would assume,” Sussman says, “herds that are well taken care of and monitored closely would have a greater survival rate. Yet, even under the optimum conditions of ISPMB herds, they still did not increase nearly 500% like BLM herds.”

It’s time for a moratorium for scientific studies like Sussman’s. We need to help the wild horses and burros not harm them. Let us use science to guide us.
