Cascade Carnivore Project Reports Wolverines Have Reproduced at Mount Rainier for Third Consecutive Year

Wolverines have reproduced at Mount Rainier National Park for a third year in a row, according to an announcement last week by the Cascade Carnivore Project.

The news marks another positive development for the project as well as the National Park Service and the U.S. Forest Service, which have been working together to document and study the "natural recolonization of wolverines in Washington and the impacts of climate change on their mountain home."

Back in 2019, a female wolverine - since named Joni by researchers - was first detected in Mount Rainier National Park. At the time, it was only the second female wolverine documented in Washington's South Cascades in modern times. Her DNA, from hair samples collected at several wolverine monitoring stations, confirmed she is part of the recovering wolverine population in Washington and that she did not disperse from a neighboring state, according to a previous news release. Researchers confirmed she had produced a litter.

Two additional litters have been documented since then, according to the organizations involved in the effort.
