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).”
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.
The news release solicits public input but does not indicate for what.
Alternative A, the Proposed Action, features forcible removal to low AML, sex ratio skewing and application of fertility control pesticides. Refer to section 2.4.
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.
We have one standard for wild horses and another standard for livestock.
As for Suckla, he’s probably sending Christmas cards and birthday greetings to TJ Holmes, the rangeland eugenicist at Spring Creek Basin.
The population climbed to 83 in March, up from 79 a year earlier, according to an undated report by NPS.
The number of births and deaths were not given.
Females outnumbered males by a margin of 1.4:1.
A population with that sex ratio should produce many more foals but it can’t because the mares have been ruined with PZP.
Contrary to a statement in the report, the herd cannot maintain genetic diversity because the breeding population is too small. Refer to 4.4.6.3 in H-4700-1.
Genetic diversity and long-term viability correlate with birth rates, not herd sizes as the advocates would have you believe.
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.
Breeding, not mass sterilization, assures long-term viability.
