Fortunately, their habitat preferences keep them pretty well confined to really rough country when they have a choice.
When I was in graduate school, I looked at a place in Central Texas that had introduced aoudads. The fellow had a section (640 acres) that was high-fenced so that the animals could not escape. He was charging for hunts. In the six years since he had released the aoudads, their numbers had tripled. Despite year-round hunting, only one animal had been harvested. This was a brushy, rocky section of land, and the aoudads knew every inch of it.
His whitetail numbers had dropped to almost nothing and the three axis deer that he had released along with the aoudads had vanished. He ended up paying a friend of mine to trap them all--an effort that took almost two years. The owner sold the live-trapped animals, but with the cost of trapping he just barely broke even.
