Did You Know?

DYK fisher release

Fishers (members of the weasel family, related to minks and otters) were reintroduced to Olympic National Park in 2008-10. They are native to the forests of Washington, including the Olympic Peninsula, but disappeared due to overtrapping in the late 1800s/early 1900s and habitat loss.
