Allegheny County Park Ranger, Braden Meiter, talked about reasons amphibians are in decline. With a special emphasis on frogs, he explained how different our world would be without them.  Frogs are important for insect control and also as bio-indicators of problems in the environment. They are a food source for bats, snakes, and other animals, including humans.   He ended on an encouraging note, showing a short film about frogs on the verge of extinction being bred for reentry into their environment.
