Frogwatch

(Thanks to Elizabeth for calling my attention to this program.)

FrogWatch USA is a Citizen Science Monitoring Program that gives YOU the opportunity to help scientists conserve amphibians! Being a FrogWatch volunteer gives you the opportunity to gather information that will help increase awareness of nationwide amphibian declines that can ultimately lead to practical and workable ways to help conserve these important species – all while helping you learn more about the wetlands in your community and the calls of frogs and toads in your community!
