What is “Native PZP” ?

PM PZP Syringe FB

We are against using anything as a pesticide on native wild horses and burros. The EPA passed PZP as a restricted-use pesticide for wild horses and burros in 2012. This gave wild horses and burros the designation of PESTS and must be reversed.

We asked Jay Kirkpatrick, Ph.D to define “Native PZP” and this is what he said.

“Native PZP is the family of glycoproteins extracted from porcine zona pellucida and administered without any alterations, such as “PZP-22″, in which the PZP is encased in a biodegradable, non-toxic material so that it has a longer duration of action (and which doesn’t work!). Research is ongoing elsewhere to find out why it doesn’t work. SpayVac is a proprietary product made in Canada and the effects of this formulation cause both uterine edema and ovarian damage. Native PZP does neither – based on a 28 year data base.” ~ Jay Kirkpatrick, Ph.D

Gunnison Sage Grouse Downgraded to “Threatened,” Allowing Oil and Gas Development and Other Threats to Continue

WIKIMEDIA

WIKIMEDIA

WASHINGTON— Bowing to political pressure, the U.S. Fish and Wildlife Service today designated the Gunnison sage grouse as “threatened” under the Endangered Species Act instead of the more protective “endangered” status proposed in January 2013. Downgrading the grouse to “threatened” will let the agency propose a special pro-industry rule to continue allowing activities threatening the grouse’s habitat, including oil and gas development, livestock grazing and urban sprawl. The grouse has been recognized as endangered since 2000 and is at severe risk of extinction.

“The undeniable reality is that the Gunnison sage grouse is in on the verge of disappearing forever,” said Amy Atwood, endangered species legal director at the Center for Biological Diversity. “It needs the full suite of legal protections that only recognition as an endangered species can provide.”

The Gunnison sage grouse’s range has declined to 7 percent of its historic range with most of the remaining populations in grave danger. The Service has acknowledged for 14 years the species needs protection under the Endangered Species Act but, following years of political interference, did not begin the listing process until after it entered into a pair of settlement agreements with the Center for Biological Diversity and WildEarth Guardians in 2011.

“The Gunnison sage grouse has been recognized as endangered for 14 years and nothing the Fish and Wildlife Service has said today makes that any less true,” said Travis Bruner, executive director of Western Watersheds Project. “This decision suggests that the Fish and Wildlife Service, in contradiction with its mandate, has placed other priorities above protection of the Gunnison sage grouse.”

The listing process for the Gunnison sage is being handled by the Fish and Wildlife Service’s Mountain-Prairie Region, located in Denver, which has repeatedly bowed to political pressure in recent months, having denied much-needed Endangered Species Act protection to the Montana grayling, wolverine and two Rocky Mountain plants.

“The efforts by agencies, counties, and the State of Colorado to conserve the Gunnison sage grouse are a step in the right direction, but full protection is needed in order to save this charismatic bird,” said Atwood.

The Gunnison sage grouse’s historic range included parts of Colorado, Utah, New Mexico and Arizona, but the species now occurs only in seven small populations in southwestern Colorado and southeastern Utah, with only about 4,700 individuals remaining. Livestock grazing, oil and gas drilling, motorized recreation and urbanization have contributed to the ongoing decline of the bird.

The Center for Biological Diversity is a national, nonprofit conservation organization with more than 800,000 members and online activists dedicated to the protection of endangered species and wild places.

Western Watersheds Project works to protect and restore public lands and wildlife in the West through education, public policy initiatives and legal advocacy.

The open forum on PZP for federally protected equids is held on Facebook here and everyone is welcome: https://www.facebook.com/groups/ForumPZPWildHorsesBurros/

Statement:

“If the good people of Nevada choose to use PZP to manage their wild horses on state land it’s up to them because that is a state issue. Americans across the country are concerned PZP isn’t safe and don’t want their wild horses and burros on federal land to be given the restricted-use pesticide hailed as “birth control” but known to sterilize after multiple use. If PZP advocates can prove PZP is 100% safe for native wild horse and burro herds, won’t sterilize them, ruin genetic variability or cause behavioral abnormalities then it could be considered as a management tool. Until then other holistic management tools must be examined. It’s time for a freeze on roundups, drugging and removals for scientific reevaluation. We need to get it right for our icons of American freedom.” ~ Anne Novak, Executive Director of Protect Mustangs

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,

Christine DeCarlo, Ph.D.

Bogus Science and Profiteering Stampeding Their Way into Wild Horse Country

 

PM Jaime Jackson

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 EPA Sterilisant

International News: American wild horse advocates seek freeze on roundups

New Zealand paper reports: 

The Bureau of Land Management is wiping out America’s wild horses,” says Anne Novak, executive director of the group. “We need to stop the roundups and protect our native wild horses.”

Protect Mustangs described the appropriate herd management level of 138 for the area as out of date and lacking in scientific merit.

“We must ensure native wild horses can survive upcoming environmental changes,” Novak says.

“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?”

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.

Science proves PZP is sterilizing wild horses

The truth

The Effects of Porcine Zona Pellucida Immunocontraception on Health and Behavior of Feral Horses (Equus caballus)

Authors: Knight, Colleen M.
Advisors: Rubenstein, Daniel I.
Department: Ecology and Evolutionary Biology

The horse population on Shackleford Banks, a barrier island off the coast of North Carolina, has been controlled using a program of porcine zona pellucida immunocontraception since 2000. Prior studies found no negative physiological effects of the immunization, but suggested some adverse effects on behavior such as increased harem switching and extended reproductive season. Although no mares were immunized in the year of study (2013), we examined the effects of past contraception and foaling on health and behavior of the mares in an attempt to better understand its impacts on both the individual and the population. Current lactation was found to be the best predictor of health and behavior: lactating mares were in worse physical condition, spent more time grazing, and switched harems fewer times. Mares that had never foaled also were in better physical condition than mares that had foaled in the past, but did not differ in behavioral measures. There were indications that the PZP treatment has had effects other than preventing pregnancy: an increased number of years since immunization was correlated with better body condition and fewer harem switches, independent of lactation. Contraception treatment intensity or timing did not have any significant adverse effects on health and behavior on its own. However, three or more consecutive years of treatment or administration of the first dose before sexual maturity may have triggered infertility in some mares. Inducing sterility, while relieving the mares from the energetic costs of lactation and reducing the stress from harem switching, may have unintended consequences on population dynamics by increasing longevity and eliminating the mares’ ability to contribute genetically.
