“Fort Worth Zoo’s Texas Horned Lizard Reintroduction Program: Trials and Tribulations”
The Fort Worth Zoo manages a large population of Texas horned lizards for reintroduction efforts in a dedicated greenhouse. This presentation will provide a general overview of their status, management of the breeding population, and research that has occurred to establish a new population of Texas horned lizards in Mason, Texas. The Zoo works closely with other breeding institutions and primary partners from the Texas Parks and Wildlife Department and Texas Christian University for this effort, which has resulted in the release of over 3,000 hatchlings since 2017.

Introduction
Diane Barber is the senior curator of ectotherms at the Fort Worth Zoo. She has worked in the zoological field for over 40 years and spearheads many conservation programs at the Zoo involving native species such as the Texas kangaroo rat, Louisiana pine snake, Houston toad, and the Texas horned lizard. She strongly believes that conservation should start in one’s own backyard and endeavors to work with local landowners and governing agencies to find practical means of coexisting and managing resources for wildlife long-term.

Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it’s the only thing that ever has.

Contribute to Citizen Science
Each year during fall and spring migrations, nearly two billion birds travel through Texas navigating with the night sky in one of the planet’s great wildlife spectacles.
However, as they pass over big cities on their way, they can become disoriented by bright artificial lights and skyglow, often causing them to collide with buildings or windows.
We encourage everyone to turn off non-essential lights at night from 11 pm – 6 am during the full fall and spring migration periods, and where conflicts apply, prioritize lights out during the critical peak migration periods.

Volunteering has many benefits, including opportunities to share your talents, learn new skills, make an impact on your community, and reduce stress.
