The Buffalo roamed as they pleased the horses don’t have that option, their restricted by fences. The amount of forage within that restricted area limits their population.
Haven’t spent much time in the west where the wild horses
are have you.....if you had you would know that they roam
VAST tracts of open unfenced BLM land. And I have HAD
wild horses on my property grazing and doing NO harm.....till some asshat from Kalifornia moved nearby, was an idiot and planted GRASSin an unfenced yard and then had the nerve to complain to the BLM that the horses were eating his grass. And THAT is all it takes for the tin god bureaucrats at the BLM to round up a herd of beautiful and harmless animals to turn them into glue and dog food.
Less than a third of wild horses rounded up by the fed gov
survive to be adopted. Most are dead within months of being corralled.
