Visions 2200 - A Perspective on the Future

Trans-Pecos Wilderness

If there is one word that would describe Texas wild lands today, it would be exotic. Texans today seem to have 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 the 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.

As can be seen from the table below, Texas' record for preserving exotic species at the end of the 20th century 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.
Most Numerous Exotic Animals Currently Inhabiting Texas
Common Name Latin Name Native Land World status per IUCN Red List Estimated Number in Texas
Axis or Chital Deer Cervus Axix or axis axis India Least concern More than 20,000 (1994)
Blackbuck antelope Antilope cervicapra India & Pakistan Near Threatened 19,000 (1982)
Aoudad or Barbary Sheep Ammotragus lervia North Africa Vulnerable 20,000 (1989)
Fallow Deer Cervus dama Linnaeus Mediterranean Least Concern 14,163 (1988)
Nilgai Antelope Boselaphus tragocamelus India & Pakistan Least Concern 15,000 (1983)
Sika Deer Cervus nippon East Asia Least Concern 11,879 (1988)

Envisioned Trans-Pecos Wilderness

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. 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 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. The wilderness would be connected to other natural areas such as Mexico's Sierra Madre, the Canyonlands, High Plains, and the Edwards Plateau via wildlife corridors.
