Oregon Spotted Frog Rearing
In early 2009, we began an unprecedented partnership with the Oregon Spotted Frog Recovery Group to rear endangered Oregon spotted frogs. The Oregon spotted frog (OSF; Rana pretiosa) is a state endangered and federally threatened species. This warm water marsh specialist has vanished from over 70% of its historic range. Under the direction of Senior Research Scientist Dr. Marc Hayes, incarcerated technicians and corrections staff at the Cedar Creek Corrections Center worked with Evergreen graduate students and other rearing institutions to augment the amphibian’s populations in the Puget Sound region. This was SPP’s first conservation program working with an endangered animal; as far as we know, it was the first prison program of its kind.

From the start, incarcerated individuals in the program proved to be fully capable conservation technicians. They followed animal husbandry protocols with care and diligence. They achieved high rates of survival and reared large, mature frogs. The support of prison staff and student coordinators was also critical, and their combined efforts brought many Oregon spotted frogs into the world: in six seasons, technicians, staff, and students raised and released 879 frogs to wetland sites!
The program operated for six seasons between 2009 and 2015.
