Better nip this in the bud, or else the estrogen crazed horses-uber-alles brigades will put enshrine these stupid pests in your national constitution and really wreck your range.
You should see the destruction left by "wild" horses in Nevada. We have over 50% of all "wild" horses in the western US in Nevada and they utter wreck the range, springs, trees, you name it. The "wild horse Annie" types will hear of no sound management proposals, thinking that these creatures are "threatened." What the WHOA types never tell you is that "wild" horses have almost no predators (other than mountain lions in high country) and left unchecked, their herd size will increase 17 to 21% every year until they encounter a hard winter or starve themselves in population collapse. By the time the latter option has happened, everything else on the range is starving too.
Then when the WHOA types start seeing how they horses starve, they'll saddle you with paying for round-ups and adoption centers. And for the horses that people won't adopt (which is the vast majority of horse gathered off the range), they'll force you to create "refuges" where the government pays private operators to graze the stupid beasts, with vets caring for them, year after year after year, at a cost of over $3/head/day.
I'm warning you: get on top of this fast, or otherwise you'll see the biggest flap and stupid tax-funded programs to care for these stupid creatures that you've ever seen, because politicians are too cowardly to tell a bunch of weepy-eyed women to "shut up, grow up and sit down."
The wild horse situation in Nevada is my "Exhibit #1" on why the 19th Amendment to the US Constitution was our single biggest mistake as a nation.
There's good management, and there's vandalism. This is vandalism.
