DESCRIPTION
The Stillaguamish Tribe previously acquired a 65-acre parcel of floodplain land along Pilchuck Creek, near its confluence with the mainstem Stillaguamish River in Arlington, WA (the Creek flows through the center of the parcel). Over the last one hundred years, the land within the project area had been cleared, graded, farmed, turned into a dirt bike track and significantly altered from its historic condition. The banks of Pilchuck Creek had been hardened and pushed closer to the water, simplifying and constraining the channel. Adjacent wetlands had been ditched and drained, and the riparian vegetation had been removed from all but a small strip of immature trees immediately adjacent to the stream channel. Before this project was undertaken, this reach lacked high quality habitat for the threatened Stillaguamish fall Chinook salmon population. In an effort to restore natural processes at this site, this grant was used to undertake a project that removed 300' of bank armoring, plant 6.4 acres of riparian area, fill 200' of drainage ditch to restore wetlands, create a 1.2 acre off-channel rearing pond (0.5 ac of which were funded by SRFB) and 200' pond outlet channel, and build four logjams. The project helped this reach of Pilchuck Creek return to properly functioning conditions and, in the process, created quality habitat for fall Chinook and all of the salmonid species passing through the project area (Coho, Chum, Pink, Steelhead, and Bull trout/Dolly Varden). In the 2005 Stillaguamish Chinook Recovery Plan, the project reach was listed as a first priority for floodplain restoration and a second tier priority for riparian restoration.
