Amphibians & Reptiles

of Tualatin River National Wildlife Refuge
Snake Eating Frog - Don Smith - 512x289


Many species of amphibians have been documented on the Refuge including chorus frogs, red-legged frogs, and non-native bullfrogs; long-toed and northwestern salamanders; and rough-skinned newts.

These species breed in Refuge wetlands and use adjacent uplands for part of their life cycles. Surveys for amphibian egg masses were conducted in late winter and spring during 2010 and 2011 on several Refuge wetlands. Results showed red-legged frogs, chorus frogs, and long-toed salamanders were breeding in Refuge wetlands.


Reptiles observed on the refuge include western pond, painted, and non-native red-eared slider turtles, alligator lizards, rubber boa, and various varieties of garter snakes. Non-native snapping turtles have been documented in the Tualatin River but have not been observed by refuge staff or volunteers.

Turtles are commonly observed basking on logs in the river or on herbaceous wetlands. Garter snakes are observed in most open habitat types throughout spring and summer. No surveys for reptiles are currently being conducted.
