DESCRIPTION
The Quinault Division of Natural Resources will survey and treat invasive Knotweed plant species in the lower Quinault River floodplain. The project area is located in the lower Quinault River floodplain from river mile 12-18 (6 miles) to cover an area of approximately 1,892 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 1,892 acres total project area surveyed, 925 acres are estimated to be infested with Knotweed and treated. Within the proposed project area, river miles (RM) 14-18 will be getting the second year of treatment. In the second year treatment area, 1,294 acres will be surveyed and an estimated 639 acres will be infested with Knotweed and treated. From RM 12-14 will be first year treatment. In the first year treatment area, 598 acres will be surveyed and an estimated 286 acres will be infested with Knotweed and treated.
The Quinault Division of Natural Resources surveyed and treated invasive Knotweed plant species in the lower Quinault River floodplain from river mile 12-18 (6 miles) which covered an area of approximately 1,892 acres. Of the 1,892 surveyed, 925 acres were infested with Knotweed and treated. Within the proposed project area, river miles (RM) 14-18 was the second year of treatment. 639 acres were infested with Knotweed and treated. From RM 12-14 was the first year treatment approximately 286 acres was infested with Knotweed and was treated. The floodplain along this particular stretch is narrow compared to the majority of the lower Quinault river. For this reason, a large area was surveyed and did not turn up a lot of large infestations.
