A plan to restore fishers, a mammal related to otters and wolverines, to the North Cascades has been delayed.
Federal, state and nonprofit agencies have been working to restore fishers throughout the Cascade Mountains, and planned to bring some from British Columbia to the North Cascades this month.
That plan has been delayed because of wildfires in British Columbia this summer, according to a state Department of Fish & Wildlife news release.
In other areas where fishers have been released, including last year at Mount Rainier National Park in the South Cascades, the animals were taken from parts of British Columbia that were impacted this year by fires.
The agencies working to restore fishers here don’t want to take animals from an area where the species recently lost habitat to fires.
“Before proceeding with restoration of fishers to the North Cascades, we must be sure that the source population in Canada remains robust and sustainable,” Fish & Wildlife’s Hannah Anderson said in the release. “Conservation of the species as a whole remains our highest priority.”
The state Fish & Wildlife Commission voted earlier this month to keep fishers on the state’s endangered species list.
Because of hunting and habitat loss, fishers disappeared from the state in the late 1800s and early 1900s, and efforts to protect and restore them to the state’s mountain regions have not yet increased the population enough to warrant removing them from the endangered species list, according to Fish & Wildlife.
Fish & Wildlife, the National Park Service and Conservation Northwest have been leading the effort to restore fishers to the state since 2008.
They have released about 160 on the Olympic Peninsula and in the South Cascades over the past decade, and are seeing evidence of survival, reproduction and population increases, according to the release.
The group is now looking for other potential sources of fishers to bring to the North Cascades.
“We’ve made great progress restoring fishers to the Olympics and South Cascades, and we anticipate resuming re-introductions into the North Cascades as soon as possible,” Dave Werntz, science and conservation director for Conservation Northwest, said in the release.
Jason Ransom, a wildlife biologist with the National Park Service, said the goal is to bring another 80 fishers to the North Cascades.
