Wild equines are going extinct. The ones corralled are the majority, being sterilized, starved, euthanized, sold for slaughter, medically tortured, and dying in filth. The ones in the wild are being sterilized, dying from injuries and infections from round-ups, and have herd #s now below genetic viability. The actual total counts may have been doubled or more to claim higher numbers to justify imprisoning almost all of them. The ones remaining cannot survive in the wild and will soon die out.

That's the plan.
