Invasive Species

Non-native invasive plants (“weeds”) crowd out our native plants...

 in forests and prairies on the Reservation, degrade fish and wildlife habitat, and invade our salmon streams.

During the field season of 2012, the QDNR Invasive Species program will target invasive Japanese knotweed in the Clearwater and Queets watersheds, lower Quinault tributaries, and the communities of Neilton and Amanda Park.  After successfully treating knotweed in Prairie Creek for five years, the program will focus on cleaning up the few remaining knotweed plants and field crews will keep an eye out for reed canarygrass, a devastating plant for wetlands and salmon migration streams, according to QDNR Invasive Species Coordinator Bonnie Eyestone. The goal of the Queets and Clearwater projects is to find all infestations from the Olympic National Park boundary to the ocean. This year’s efforts are funded by grants from the U.S. EPA and Washington’s Salmon Recovery Funding Board.

The Quinault Indian Nation has been managing invasive species for more than 10 years, initially focusing on gorse in the Queets region of the Reservation.  In the future, QDNR will broaden the Invasive Species Program from knotweed to other invasive plants such as Scotch broom, gorse and reed canarygrass that negatively affect fish, wildlife, native plants, and timber. Waterways will be monitored for invasive zebra and quagga mussels. Many forest pests – insects and diseases – are also considered “invasive species” and are being monitored.
