Texas Amphibian Watch groups report data about amphibians to Texas Parks and Wildlife, the sponsor of the program. This data is used by scientists. Because amphibians use wetland habitats during at least part of their life cycle and because they have permeable skin, ecologists believe that declines in amphibian populations and malformations may serve as early warning indicators of broader changes in ecosystems.

Volunteer “watchers’ meet as a group once a month, March through October, around sunset, to monitor signs of amphibians, particularly frogs. The groups meet at Sunset Bay, White Rock Lake in Dallas, and sometimes at the Trinity River Audubon Center.
