Greater Vancouver Zoo First time Captive Bred Endangered Oregon Spotted Frogs to be released to the wild
Aldergrove – Another exciting year of great conservation work has been achieved at the Greater Vancouver Zoo with the endangered Oregon Spotted Frogs. We are extremely proud as this was the first year that we attempted breeding the frogs in a captive environment, which proved to be very successful!
Tomorrow staff from the Zoo along with wildlife biologists from the Oregon Spotted Frog Recovery Team will be releasing tadpoles into their natural wetland environment near Agassiz, BC, in an area specifically modified and enhanced to meet the Oregon Spotted Frogs habitat needs.
It is hoped that these tadpoles, in addition to frogs reared throughout the summer, will survive till breeding age ensuring the survival of this unique species in Canada.

The IUCN (International Union for Conservation of Nature) Red List of Threatened Species lists the Oregon Spotted Frog as “Vulnerable”, and they are listed as “Endangered” in Canada. Oregon Spotted Frogs are endangered because they constantly have to face threats from tremendous loss of suitable habitat due to draining of wetland habitats, introduced bullfrogs, green frogs and predatory fish that eat the tadpoles and young frogs. Another potential threat is the chytrid fungus which is native to Africa and has caused significant loss of amphibian populations in many parts of the world.
The Oregon Spotted Frog is now limited to four sites within BC, one in the Aldergrove area and three in the Agassiz area. The Oregon Spotted Frog Recovery team was formed in 1999, when the Committee for the Status of Endangered Wildlife in Canada (COSEWIC) first designated the frog as “endangered”; in order to save the species. The species is also Red-listed in B.C. The team is comprised of biologists from BC Ministry of Environment, BC Ministry of Forests, Lands, and Natural Resource Operations, Canadian Wildlife Service, Department of National Defense, Seabird Island Band, Stó:lo Tribal Council, Greater Vancouver Zoo, Vancouver Aquarium, Toronto Zoo, Grouse Mountain Refuge for Endangered Wildlife, and Simon Fraser University.
The Greater Vancouver Zoo has been actively involved with the recovery team and the head start program of this species since it was declared endangered in 1999.
