Amphibia    Anura    Ranidae  

Cascades Frog
Rana cascadae Slater, 1939

SSAR 9th Edition Comments:
 The disjunct populations in the Olympic Mountains, Washington, and the Klamath-Siskiyou Mountains, California, should be investigated with respect to call characters and molecular data. Previous studies on the populations have produced conflicting results (Dodd, 2023, Frogs of the United States and Canada, 2nd edition, Johns Hopkins University Press: 992pp).

Range maps are based on curated specimens and provided gratis by CNAH.
