Flora/Fauna: Since the depth of the cave reaches below
the water table, there are freshwater lakes around its interior perimeter.
These lakes support two unique organisms; one, an endemic amphipod, and the
other, a rare aquatic isopod. Both these organisms are crustaceans. Also, the
walls of the vertical shaft of the cave support a Mexican fern species found
in few other locations in the United States. Plateau liveoak is the dominant tree
species on the Edwards Plateau. There are rather deeply cut canyons on the
southern end of the site. These canyons provide a more mesic environment and,
therefore, support trees such as escarpment black cherry, Buckley oak, Lacey
oak, and pinyon pine. . The endangered species of breeding
Black-capped Vireos live in the Natural Area. The Tobusch fishhook cactus is also an
endangered species and is in the park |
