The BLM has not yet identified an immunocontraceptive method that has been proven to reliably and humanely sterilize wild mares according to the Silver King EA, published earlier this week (page 136 in the pdf).

An oocyte growth factor vaccine is currently under testing for its ability to cause long-term infertility or, potentially, sterility.

As for the approved methods, “Mares that received 5 or more doses of ZonaStat-H vaccine have been shown to have reduced ovarian function, and to be effectively infertile for life (Nuñez et al. 2017), and it is conceivable that the contraceptive effects of repeated treatment with GonaCon-Equine may last longer than a mare’s lifespan, depending on the mare’s age at treatment and the number of doses received (Baker et al. 2018, 2023).”

Researchers at Purdue are working on a formulation that does the job with one shot.

The advocates, evil beyond imagination, are not waiting for scientific breakthroughs.

They’re demonstrating the feasibility of mass sterilization at the Salt River, Virginia Range and elsewhere.

The pesticides do not kill horses, as stated on page 15 of the EA, they kill herds, much to the delight of the ranchers and their political allies.

They need a way to make their lies seem plausible.

The faulty hypothesis is the sperm-blocking theory.

If you stand in the rain with an umbrella, you don’t get wet.

If you set it aside, you get wet.

Hold it up, you stay dry.

Let it down, you get wet.

The umbrella blocks the rain.

Here’s how PZP really works.

If you hold up the umbrella for an hour, you can let it down for an hour before you get wet.

If you hold it up for two hours, you can let it down for two hours before you get wet.

If you hold it up for at least five hours, you can get rid of it.  You won’t get wet no matter how long the storm lasts.

The umbrella made you impermeable.

The distinction between the “historically accepted hypothesis” and a “complementary hypothesis,” which asserts that impermeability is the result of damaged or destroyed ovaries, is discussed on page 135 (138 in the pdf) of the Silver King EA.

Why would Larry Don Suckla, a Colorado Republican, be so interested in a bill crafted by liberals, signing on as a cosponsor?

Because he runs cattle in Gypsum Valleys, a short distance from the Spring Creek Basin HMA.

The bill, if signed into law, would help the state buy pesticides to beat the horse populations down in favor of livestock.

The allotment master report puts Gypsum Valleys in the Improve category, suggesting that your stewards of the public lands are not taking their responsibilities seriously.

The allotment offers 1,777 active AUMs on 41,187 public acres, equivalent to 3.6 wild horses per thousand public acres.

The target stocking rate across all HMAs is one wild horse per thousand acres.

Above that, rangeland health will suffer according to your faithful public servants.

Yet they allow almost four times as many animals per public acre in Gypsum Valleys, another example of management duplicity.

As for Suckla, he’s probably sending Christmas cards and birthday greetings to TJ Holmes, the rangeland eugenicist at Spring Creek Basin.

This column has always been dedicated to the wild horse advocates, who are wrong about everything, especially the importance of reproduction to herd survival.

How can you start a nonprofit and attract a large following yet be so out of touch?

As a gentle reminder of their errors, add comments to their socialist media pages about the consequences of their darting programs, such as abnormal sex ratios, injuries and infections, increasing death rates and loss of genetic diversity.

Links to anything on Western Horse Watchers would be most unwelcome.

It won’t change their minds but it might dissuade others from joining their movement.

The product may break the cycle of mother bears teaching their cubs to break into houses according to a report by the Tahoe Daily Tribune.

In keeping with established practice, the article refers to it as a vaccine, not a pesticide.

It’s not clear if the writer consulted with the wild horse advocates, who use it to stop mares from teaching their foals to survive in the desert.

The story pointed to MOUs with departments of agriculture in Arizona and Nevada, a reference to the mass sterilization programs at the Salt River and Virginia Range, showing that partnerships with state agencies are possible.

Curiously, a representative of the Billings School of PZP Darting and Public Deception said the advocates weren’t trying to decrease the population of black bears, just prevent them from teaching their cubs to break in.

There is a problem with their plan, however: PZP is not approved for use on bears.

A 2017 labeling amendment expanded its scope to white-tailed deer and other cervids but not to ursids.

So not only will the advocates at Lake Tahoe need to get certified at Billings, but they’ll also need to convince the EPA that the pesticide is suitable for bears.
