The Quinault Indian Nation requests SRFB grant funding in the amount of $255,000 to continue presence/absence surveys and treatment of non-native invasive plants (knotweed, reed canary grass, scotch broom and non-native blackberry) in the lower Quinault River floodplain. The project area is located in the lower Quinault River floodplain from river mile RM 18.0 to RM 22.5 (4.5 miles) with a surface area of approximately X,XXX acres. The grant funds would be supplemented by $45,000 in matching funds provided by an EPA grant and in-kind from the QDNR Invasive Species Specialist. The SRFB grant would provide funding necessary for QIN to continue its invasive plant treatment and control program in the lower Quinault River watershed. Continued treatment and control of knotweed and target invasive species would provide opportunity to reestablish native plants and trees in the floodplain through future seeding and forest restoration planting in order to improve floodplain forest functions and the services they provide to salmon and wildlife. Restoration of native vegetation and forests in the lower Quinault River floodplain following invasive plant treatments would provide benefits to mainstem, side channel and off-channel habitat quality and help to restore natural habitat forming processes and ecological functions provided by healthy riparian plant communities. Quinault River salmonids benefitting from improved floodplain forest conditions and aquatic habitats would include Chinook
