Only one year have I ever seen the game suffering on these ranches and that was about the 3rd year of a severe draught, Bud. The owners take range/game management very seriously to avoid overpopulation. Two helicopter game counts per year are taken on all three ranches annually before game quotas for native wildlife and exotics are determined.
After three years of draught, all of S. Tx was in bad shape; ranchers were hard pressed to find hay for livestock, many selling off large portions of their stock. Here's a couple of pictures taken that year.
