Getting rid of wild horses with helicopters is bad, according to the advocates, but getting rid of them with contraceptives is good, so let’s take a closer look at the idea.
How long would it take to cut the size of a herd in half?
If the birth rate is zero, courtesy of the advocates, and the death rate is 5% per year, about fourteen years.
If the death rate is 10% per year, about seven years.
How long would it take to cut the herd by 80% (e.g., 500 to 100)?
Assuming the birth rate is zero and the death rate is 5% per year, 32 years. If the death rate is 10% per year, about 16 years.
That means the advocates would have to dart the mares for at least 16 years to get the population down to AML?
No. The mares would be sterile after five years, so they could walk away and ruin another herd.
There’s no point in discussing acreage, AMLs, stocking rates, resource allocations and genetic viability, because, under their plan, none of those things matter.
