Trans-Pecos

Desert Bighorn Sheep
If there is one word that would describe Texas wild lands today, it would be exotic. Texans has an affinity for exotic animals, especially deer and antelope, that are not native to the state. From 1963 to 1994, the exotic population in Texas grew from about 14,000 animals of 13 species to more than 195,000 animals and 71 species. 

The chart below lists six exotic animals now roaming free in the state in such numbers that they must be considered permanent additions to the mammal fauna according to The Mammals of Texas by David J. Schmidly. According to the chart, Texas' record for preserving exotic species seems to lean toward those least in need of help. None of the species fall within the two categories most vulnerable to extinction: (1) critically endangered and (2) endangered. Only one is included within the third most concerned category: vulnerable.

There are cases where ranchers have benefited endangered animals from elsewhere. The price, however, has been hunting, which the ranchers say is necessary to pay for the upkeep of the rest of the animals. This has been controversial

Envisioned Wilderness

 


Addax Antelope
This wilderness, envisioned as located in the Trans-Pecos region of West Texas and a portion of New Mexico, would be populated with antelope and other animals that can thrive in this hot and dry climate.

The satellite view Above shows the proposed wilderness area with orienting geographic features and cities. Prospective wildlife corridors are also indicated. The wilderness would be connected to other natural areas such as Mexico's Sierra Madre, the Canyonlands, High Plains, and the Edwards Plateau via these wildlife corridors.

Mountain Nyala Antelope
Emphasis would be on species that are truely endangered and will not out-compete native species. Predators that can cull out weaker creatures and keep numbers within the capacity of the natural environment would also be included.

Animals proposed for inclusion in this wilderness are indicated in the chart below. Exotic species (not either native, previous occupants of area, or naturalized) are in italics and a darker gray background, with their endangered status indicated. All the exotic animals are in one of the four most endangered categories (CR, EN, VU & LR) or are extinct in the wild (EW) according to the IUCN.
