Feral hogs do just fine in all but the harshest deserts. Every Texas county has hogs including Big Bend and Pecos County which are very dry and technically arid not semiarid. Hog hunting is a guilty pleasure of mine and some of the best is in the wide open scrublands of West Texas at night using thermal scopes and NVGs. Hogs are found in every continent in the wild except if Antarctica other than humans they are the most adaptable species on earth. The little female ones make dang fine pit smoking pigs we call them Webber pigs. If they fit in a barrel smoker once splayed out that’s good eats.

I live in the Sonora desert, which is a severe desert.
The few times I have been able to eat meat from feral pigs, it was delicious.
