Montgomery County is a chapter in the nationwide FrogWatch USA program! Our chapter is an exciting way for individuals and families to participate in citizen science and to learn more about amphibians and the wetlands they live in. The Montgomery County chapter has existed since 2014 and is kicking off its 7th year of monitoring in 2020!


Frogwatch LogoWhat is FrogWatch USA?

FrogWatch USA is a nation-wide volunteer frog and toad monitoring program run by the Association of Zoos and Aquariums (AZA). Volunteers are trained to identify frog and toad calls at a wetland site and to report their data online. Data is compiled and analyzed to develop conservation strategies for frog and toad species, and their habitat.


Why are Frogs and Toads Important?

Frogs and toads are pollution sensitive organisms and are indicators of environmental health. Frogs and toads are both predators and prey, serving an important role in aquatic food webs. As predators, tadpoles help clean waterways by feeding on algae and adult frogs and toads feed on insects that can be pests and transmit diseases, such as mosquitoes. They also serve as a food source for many other organisms.

Volunteer Commitments:

Montgomery County will provide a volunteer training session every year in January or February and up to three field trainings at a site during the monitoring season. Throughout the breeding season from February to August, we ask that you commit to monitoring a wetland site for a three minute period 30 minutes after sunset weekly. You have the option of monitoring a pre-registered site by the County or registering your own site.

Staff are able to assist in registering sites.
