The 2006 season marked the 10th year that Texas volunteer scientists have helped the Texas Parks and Wildlife Department (TPWD) gather data on our official state reptile, the Texas Horned Lizard (THL) (Phrynosoma cornutum). During the course of the monitoring project, 186 volunteers have officially submitted data to the program. Three volunteers and their families have collected data from a site during all 10 years. To date, 270 sites have been adopted for monitoring. Data have been gathered from 165 counties. THL have been reported from 146 of those counties. Results have helped shed light on the current distribution of Texas Horned Lizards and characteristics of their habitat.
