Portland, OR (September 21, 2018) – Citing violations of the U.S. Constitution and three federal laws, an alliance of wild horse protection and animal welfare advocates filed a lawsuit today in the U.S. District Court in Portland. The groups seek to enjoin the Bureau of Land Management (BLM) from proceeding with controversial and dangerous surgical experiments to remove the ovaries of wild mares at BLM’s Wild Horse Corrals in Hines, Oregon.

The complaint was filed on behalf of The Cloud Foundation (TCF) and its executive director Ginger Kathrens, who is also the Humane Advocate on the BLM’s National Wild Horse and Burro Advisory Board; the American Wild Horse Campaign (AWHC); the Animal Welfare Institute (AWI); and wildlife photographer Carol Walker, who is also a Director of Field Documentation for the Wild Horse Freedom Federation, by Nick Lawton of the public interest law firm Meyer, Glitzenstein and Eubanks LLP.

A key demand of the legal action is the right to meaningful public observation and video recording of the experiments to improve public awareness of how the BLM is treating these federally protected wild horses and help the public inform BLM that this inhumane form of sterilization is not socially acceptable..

“To date, the BLM has refused to allow a meaningful opportunity for media or the public to observe and record these procedures,” said Nick Lawton of Meyer, Glitzenstein and Eubanks. “The BLM’s refusal to allow meaningful access to observe and record these experiments thwarts the important newsgathering objectives that Plaintiffs aim to achieve by observing and documenting the BLM’s treatment of wild horses, and thus violates Plaintiffs’ rights under the First Amendment of the U.S. Constitution.”

The legal action also alleges that the experiments, which involve performing an outdated surgical procedure called ovariectomy via colpotomy (a blind surgery in which a veterinarian inserts his arm into a mares’ abdominal cavity through an incision in the vaginal wall, manually locates the ovaries, then twists, severs and removes them using a rod like tool with a chain on the end) are unscientific, inhumane and dangerous, and will result in pain, suffering and potentially life-threatening complications for wild mares.

Video of the procedure, which as been called “barbaric” by equine veterinarians, can be seen here.

This is the BLM’s second attempt to conduct research on the surgical removal of the ovaries of wild mares. In 2016, AWHC and TCF sued to uphold their first amendment right to observe the experiments, a major objective of which was to determine the social acceptability of the procedure. The BLM cancelled the experiments, which it intended to conduct in partnership with Oregon State University — instead of providing public observation.

In its renewed attempt to conduct the research this year, the BLM dropped the objective of determining social acceptability in order to avoid providing meaningful observation. Instead, the BLM is offering limited observation through the doorway of a room adjacent to the surgical suite on a first-come, first-served basis with no independent veterinary observation provided.

When the agency re-released the sterilization research proposal, the BLM announced that it would be conducting the experiments in conjunction with Colorado State University (CSU). The University was to provide expertise in monitoring and assessing the welfare impacts of the surgeries on the wild mares. However, in August, CSU withdrew from the project. Instead of finding another academic institution with expertise in animal welfare monitoring and assessment, the BLM dropped CSU’s scientific observation of animal welfare from its study design.

Then, on September 13, 2018, the BLM announced that it was moving forward with the spay feasibility study despite opposition from the public and veterinarians, a warning from the National Academy of Sciences that the procedure was “inadvisable” due to health risks, and after two major research institutions – CSU and OSU – ended their affiliations with the project.

As soon as next month, the BLM plans to start rounding up 100 percent of the wild horses in the Warm Springs Herd Management Area in southeastern Oregon. An estimated 685 horses will be permanently removed and another 100 mares will be surgically sterilized. The experiments carry a high risk of mortality from bleeding, infection and evisceration (fatal protrusion of bowel through the surgical incision) and will subject pregnant mares to risk of miscarriage and associated complications. (More details on the BLM’s plan can be found here.)

“The BLM’s proposal to spay wild mares, many of them pregnant, without any adequate oversight or care for their pain, suffering and possible deaths is completely indefensible and unacceptable” said Carol Walker, Wild Horse Freedom Federation. She continued,

”We must do everything we can to ensure that our wild horses are treated humanely and with compassion, and continue to be protected under the 1971 Wild Free-Roaming Horse and Burro Act.”


The American Wild Horse Campaign (AWHC) is a national wild horse advocacy organization whose grassroots mission is endorsed by a coalition of more than 60 horse advocacy, public interest, and conservation organizations. AWHC is dedicated to preserving the American wild horse in viable, free-roaming herds for generations to come, as part of our national heritage.

The Cloud Foundation (TCF) is a Colorado 501(c)3 nonprofit corporation, that grew out of Executive Director Ginger Kathrens’ knowledge and fear for wild horses in the West. TCF works to educate the public about the natural free-roaming behavior and social structure of wild horses and the threats to wild horse and burro society, to encourage the public to speak out for their protection on their home ranges, and to support only humane management measures. Kathrens serves as the Humane Advisor on BLM’s National Wild Horse and Burro Advisory Board.

The Animal Welfare Institute (AWI) is a nonprofit charitable organization founded in 1951 and dedicated to reducing animal suffering caused by people. AWI engages policymakers, scientists, industry, and the public to achieve better treatment of animals everywhere—in the laboratory, on the farm, in commerce, at home, and in the wild.

  1. Medical Malpractice Related to Unnecessary Surgery
    By Law Offices of Barry G. Doyle, P.C.
    “Unnecessary surgery is a type of medical malpractice. A form of medical malpractice that has become an alarming and growing problem in the U.S. is unnecessary surgery.
    This type of malpractice can lead to life-threatening complications and completely alter an individual’s life. When a surgeon performs and unnecessary surgery, it is an act of medical negligence. Doctors should take every precaution before deciding to prescribe any type of invasive surgery to a patient. When there is a failure to do this and it results in unnecessary surgery, they may be held legally liable. Unnecessary surgery can lead to serious or even life-threatening complications. Some of the risks include hemorrhaging, damage to organs, infection, amputation and anesthesia errors. Putting animals through unnecessary surgery where they face complications that could significantly alter their life is a form of medical negligence.”


    • Spoke last weekend with a retired equine veterinarian who had not heard of the BLMs fixation on spaying mares. The information I received indicated in that person’s estimation a fatality rate of 80-85% was to be expected in domestic mares. This vet worked mostly on race and ranch horses and has high integrity. I post it here just as more evidence of the serious risks these surgeries present, and the sheer folly of pursuing them on publicly owned wild mares.

      Since we are expected to pay for this without complaint or substantive access and documentation, can someonw tell me how to find the government form which lets me opt out of supporting and paying for the BLMs bloody mare mutilation fixations?

  4. No mention of the intentional skewing of normal behaviors by the removals and dislocations, nor of the gender component of horses released. So taking 100 mares from their homelands and releasing them into adjacent fenced enclosures in unnatural congregations makes zero scientific or behavioral sense, especially since the area will be emptied of all the rest of them. What they are creating here is a zoo environment disguised as “science” which has no public purpose other than to exterminate wild horses. That many will be pregnant and abort or miscarry seems to be of no consequence, and in the context of the helicopter harassing a miscarrying mare in Nevada makes it clear equine life has no value to those who are their paid caretakers.

    I value credible science, which starts with an approved hypothesis which is then tested. The gold standard is “reproducible results” which this study can never deliver. What exactly is the hypothesis here? What possible value will the results provide? What better ideas languish without funding as taxpayer dollars are spent in this pointless bastardization of true scientific inquiry?

    There is NO public benefit to spending taxpayer funds to harass, terrorize and kill wild mares, and no prospect of any results being replicable in other distinct herd environments.



    “The first four years of this EA deal with a spay study that will begin this year by rounding up 100% of the horses and burros in the HMA, primarily using helicopters, and then spaying over 100 mares!

    Located in Hines, Oregon, the HMA encompasses 474,547 acres and it is currently estimated that 738 adult horses and 147 foals live in the HMA. After the BLM rounds-up 100% of the horses, 100 horses will be returned to a fenced in area of the range as the control group and 100 horses will be returned to an adjacent, fenced in area as the treatment group. The remaining approximately 685 horses will be permanently removed from the range.

    The EA is considering an extremely controversial and dangerous surgical spay procedure—ovariectomy by colpotomy. In the study, 28-34 mares will be spayed by this horribly inhumane procedure. Eight mares will be released into the treatment group without the spay procedure. An additional 70 mares will be spayed but not returned to the range at all. These 70 mares are spayed only to contribute to the complication rate of the study.
    The study will conduct this painful procedure on mares that are three years of age and older. However, and worst of all, the procedure will be conducted on mares that are in three different gestational groups: not pregnant, early term (less than 120 days), and midterm (120-150 days). There is a known, extremely high risk of abortion in the early to mid- term pregnancies following this procedure.”
