The Washington Department of Fish and Wildlife (WDFW) released hundreds of an endangered frog species into the Columbia National Wildlife Refuge last week.

Native to the Pacific Northwest, the northern leopard frog used to be all over North America. Over time, their numbers have rapidly diminished in parts of Washington, Oregon and western Canada.

“The Washington state population of northern leopard frogs has a unique genetic variation relative to the rest of the species range, and they are part of the natural diversity of amphibians of the region,” said Erica Crespi, WSU associate professor of biology.

“We are working to keep them here!”

WDFW first collected northern leopard frog eggs back in the spring of 2021. After several months of growing in the Oregon Zoo and Northwest Trek, the frogs were ready to be released.
