Biology
Cascades frogs (Rana cascadae) are small frog of the family Ranidae that range from 33 to 77 cm in length and 8 to 31g. They live at elevations ranging from 1300 to 8000 ft (400-2500m).
Breeding occurs in ponds and lakes between March and August, depending on latitude, elevation, and snowmelt.
Tadpoles develop into frogs in a single season, typically between 6 and 12 weeks.
It is thought that juvenile frogs take approximately 5 years to become mature adults.
Cascades frogs can live for more than 15 years.
The species ranges from northern California to northern Washington, and may extend into British Columbia, Canada.
Cascades frogs have been extirpated (become locally extinct) from all but a few locations in northern California.
