By simply overturning a rock in a streambed, one may discover various amphibian species while visiting the park. Amphibians have both an aquatic larval stage and a terrestrial adult stage. For this reason they are considered effective indicators of pollution and water quality. Amphibians breed after significant spring rainfall events and females lay eggs in ponds, streams, and springs throughout the park. Depending on the species, metamorphosis can take from days to weeks to be completed.
