Oregon Spotted Frog

description Oregon Spotted Frog Overview

The Oregon Spotted Frog (Rana pretiosa) is a medium-sized amphibian native to the wetlands and marshes of the Pacific Northwest, including regions of Washington, Oregon, and British Columbia. It is a highly aquatic species that relies on warm, shallow water bodies for breeding, feeding, and shelter throughout the year. The frog is characterized by the distinct dark spots on its legs and back, which contrast with its generally brown or reddish-brown skin. Due to significant population declines driven by wetland drainage, invasive predators, and climate fluctuations, it is protected as a threatened species under the U.S.

Endangered Species Act.
