Once abundant throughout Texas, the Texas Horned Lizard’s population has declined or disappeared altogether in many parts of the state, so much so that it is now on the state’s threatened species list. To preserve the abundance of the State Reptile of Texas, San Antonio Zoo launched the Texas Horned Lizard Reintroduction Project. This program uses GIS data, genetics, and current knowledge about horned lizard ecology and distribution to release large numbers of captive-born individuals in suitable habitats.
