Even though much of Crater Lake National Park is covered in pumice, ash, and other volcanic rock, wetlands are abundant. Within the many streams, wet meadows, and the lake shore, eight species of amphibians are found.These include three frog and one toad species, two salamader species, and two newts.

The Mazama Newt,Taricha granulosa mazamae, is an endemic species to Crater Lake National Park. It only lives along the shores of Crater Lake and Wizard Island. It is a subspecies of the rough skinned newt,Taricha granulosa, which happens to be the only newt found in North America, from Central California to Southeastern Alaska.

The Pacific tree frog (Pseudacris regilla) also known as Pacific chorus frog is about 2 inches (5 cm) long. Aside from its small size, a key identifying characteristic is a continuous dark stripe from the front shoulders, up to and across the eyes, and through the nose. These frogs have a vast color range from green, tan, brown, gray, reddish, and cream, but most often are green or brown. Contrary to the tree frog's common name, it is mostly a ground-dweller, living in tall vegetation near water, but occasionally is found climbing on trees. Large toe pads allow it to climb easily, and cling to branches, twigs, and grass.

The Cascades frog (Rana cascadae) is named for its home region. Rana is Latin for frog and cascadae refers to the Cascade Mountains. About the size of a small child’s hand, these mountain dwelling amphibians are usually found above 2,400 ft (730 m) elevation in wet meadows, forest bogs, lakes, ponds, and small streams. They rely on clean and permanent water sources for survival and are recognized as a species of concern in California, Oregon, and Washington.
