Beaver Marsh Trail - #7 - Amphibians
Amphibians of Beaver Marsh
Amphibians are a large and diverse group of vertebrates. There are 3 groups of amphibians: frogs and toads (anura), salamanders (caudata), and caecilians (gymnophiona). Of the 3 groups, only frogs and salamanders are found in North Carolina.
Frogs and Toads
Amphibians are found in almost every habitat on every continent except the polar regions of Greenland and Antarctica. In many ecosystems they are abundant and play important roles in many food webs. Many amphibians are considered indicator species because they are very sensitive to environmental conditions. Amphibian studies can provide important information about the health of an ecosystem and how changes might affect other species of plants and animals.
Habitat loss and degradation are the largest threats to amphibian species. Many species are also threatened by infectious disease and climate change. Organizations like ECWA protect and restore areas like the Beaver Marsh that provide valuable habitats for amphibians and other wildlife.
