Fisher Restoration Continues
Thirty-one fishers have been released into Olympic National Park so far this winter, in the second year of a three-year project to restore these animals to Washington and the park.
Biologists released two female fishers in the Hoh Rain Forest on Monday, February 23 in the last release of this winter.
About the size of a cat, and related to minks and otters, fishers vanished from Washington State decades ago because of over-trapping, and habitat loss and fragmentation. Over the duration of this three-year project, biologists hope to release a total of approximately 100 fishers within the park.
Each fisher is fitted with a tiny radio transmitter before release so that researchers can monitor their movements and survival. More information, including monthly updates from the monitoring effort, is available online.
Of the 49 fishers released so far, biologists continue to monitoring 40. Four animals are known to have died since their release; three are suspected to have died but have not been recovered and two radio transmitters are no longer functioning.
This project is possible through a partnership of agencies and organizations, with project management provided jointly by Washington Department of Fish and Wildlife and Olympic National Park. The U.S. Geological Survey, Washington Department of Fish and Wildlife, and Olympic National Park are leading a research program, including monitoring, to evaluate the success of the reintroduction. Other partners and cooperators are providing financial or logistical support for management and research tasks.
