In 2015, KPC engaged a local ecologist to conduct a feasibility study on the potential reintroduction of four iconic prairie species that had been extirpated from the Katy Prairie Preserve and its environs. The four species under consideration were Texas Horned Lizard (Phrynosoma cornutum), American Bison (Bison bison), Houston Toad (Bufo houstonensis), and the endangered Attwater's Prairie Chicken (Tympanuchus cupido attwateri). The results of this study surmised that there is a good prospect for the near-future reintroduction of Texas Horned Lizard, a long-term prospect of reintroduction of Attwater's Prairie Chicken and Bison, and that the reintroduction of Houston Toad was very unlikely.
