Through a partnership with the Texas Parks and Wildlife Department, Texas Christian University and a private landowner, the Fort Worth Zoo located the first reintroduction site that fits the environmental and habitat models needed for Texas horned lizard (Phrynosoma cornutum) survival. Horned lizards hatched at the Zoo have been released in the site at various ages and tracked to determine the most effective reintroduction methods. Although translocation projects have been attempted, there has never been a successful ongoing horned lizard reintroduction program. Staff continued to track horned lizards with transmitters in recent years. Horned lizards will continue to be released at various ages and will be fitted with different sized transmitters to determine the best reintroduction methods. The Fort Worth Zoo is one of the only zoos in the country to successfully breed the Texas horned lizard. Since 2005, the Zoo has facilitated more than 300 hatchings.
