Since 2008, wildlife biologists in Washington state have worked to reintroduce the fisher, a locally-extinct forest weasel. They are not shouting from the tree tops about success, but say things are looking positive. Fishers were previously reintroduced in the southern Oregon Cascades.

There’s no way to know for sure how many fishers lived in the Cascades historically, because the small brown mammal was almost entirely eradicated by trappers by 1930.

But this week, there’s evidence that they are reproducing.
