DESCRIPTION
Project Description: Include 1) project location, 2) overall goal, 3) primary habitat type, 4) priority (target) species, and 5) describe what will be acquired, restored, assessed, designed and/or inventoried. 1) Lower Quinault River from RM 14 to RM 10 2) reduce knotweed densities to maintenance levels 3) riparian 4) chinook, coho, chum, steelhead 5) treatment of non-native knotweed species to improve opportunity for natural recolonization and restoration of native vegetation within the riparian corridor and floodplain of lower Quinault River. 5) Treatment locations are inventoried for future monitoring activities. Native riparian vegetation communities will be restored in subsequent seasons.
The Quinault Division of Natural Resources surveyed and treated invasive Knotweed plant species in the lower Quinault River floodplain.
The project area was located in the lower Quinault River floodplain from river mile 8-14 (6 miles) which covers an area of approximately 1,796 acres. The priority Quinault River salmon species benefitting from improved floodplain forest conditions and aquatic habitats include Chinook, Chum, Coho, Sockeye, Steelhead, and Cutthroat.
Of the 1,796 acres total project area surveyed, 855 acres were infested with Knotweed and treated.
Within the proposed project area, river miles (RM) 12-14 received the second year of treatment. In the second year treatment area, 1,132 acres was surveyed and an estimated 529 acres was infested with Knotweed and treated.
From RM 8-12 was the first year treatment. In the first year treatment area, 664 acres were surveyed and 326 acres were infested with Knotweed and treated.
