Frogs (like all amphibians) are tremendously important for controlling insect pests and in turn serve as building blocks in many food chains. While amphibians were the first vertebrate animals to spread across terrestrial habitats of our planet, with their moist permeable skin they remain tied to clean water for reproduction and their very survival. Today many of these beloved creatures are in serious trouble due to habitat loss, pollution, invasive species, fungi and diseases. Pennsylvania is home to numerous amphibians species including frogs, toads, newts and salamanders that breed in fish free vernal pools. Join your DCNR Park Naturalist for a trailside interactive exhibit program on our vanishing amphibian friends, their natural history histories and what we can do to help them.
