Have you found the books Clark gave to elementary school libraries? This year’s book is Drop: An Adventure through the Water Cycle

Amphibians, which include frogs, toads, salamanders, and newts, are cold-blooded vertebrates that require specific wet environments. These animals breathe and absorb water through their skin! Because of this, amphibians are extremely sensitive to temperature and weather changes, as well as toxins in the ecosystem.

The American bullfrog, which is not native to the state, is the largest frog in Clark County. The Oregon Department of Fish & Wildlife reared and released them in the 1900’s and yearly flooding of the Columbia River dispersed them over to the Washington side.

Dunn’s salamanders can be found in the rocky forest habitats near seepages, streams, and water falls. They require these moist habitats because they lack lungs and breath through their skin. They eat small invertebrates including worms, centipedes, moths, ants, and beetles.

Northern red-legged frogs are insectivores and their home range can be several kilometers. They like wooded habitats. In the spring, when they are moving to breeding sites, you can smell them with a little practice.

These frogs, also called tree frogs, can change color from brown to green or vice versa or a combination of both in response to environmental conditions. Pacific chorus frogs that were underground in the blast zone during the eruption of Mt. St. Helens were one of the few vertebrates to survive.

Rough-skinned newts inhabit both terrestrial and aquatic habitats. Most of their populations are extremely toxic but can be predated on by common garter snakes (Thamnophis sirtalis), which are immune. Ducks and herons have also been known to eat them.

Long-toed salamanders live in diverse habitats including coniferous forest, oak woodland, and marshland communities. They lay their eggs in springs, ponds, small lakes, and marshlands. Migration to those breeding waters begins in winter.

The western red-backed salamander can be found along stream banks and in shady forests under rocks and fallen logs. They lay their eggs on land and unlike most salamanders, their larvae hatch fully formed with all their legs.
