There is a big difference between horses grazing on land and cows and buffalo . You can have a heck of a lot more cattle grazing the same land than horse for the simple reason that horses DESTROY the grass by pulling up the roots .
The buffalo were located in a grassland. These horses are in a desert, with very little grass available.
