SRP Project

DESCRIPTION

This project would support the removal of one large log stringer bridge, built in the 1960's, in the upper mainstem of Ellsworth Creek. The bridge is deteriorating and while failure is not imminent, it is becoming increasingly likely and would result in significant impacts within this salmon bearing stream. Rather than replacement, the Conservancy is choosing to completely remove the bridge and all associated fill from the site and to back out about 800-1000 feet of road through additional decommissioning. An in stream habitat inventory of the entire Ellsworth stream system shows that this part of the system has low volumes of large wood in the stream. Evidence of past extraction of large wood is evident which was often required by forest practices at the time this area was logged. The impact to stream complexity and function has been significant, resulting in a reduced capacity for the stream to support salmonids. The project will assess conditions of 1 mile of stream habitat and design the placement of large wood in specific locations where it will help restore instream habitat and/or enhance connectivity and condition of off-channel habitat in this portion of TNC's Ellsworth Creek Preserve. About 2000 feet of adjacent stream will be enhanced at the time the stringer bridge is removed and the remainder will be treated in 3 to 5 years when TNC conducts restoration logging adjacent to that area. Implementation of that portion of the work will be the focus of a future project.

Fieldwork for the Ellsworth Creek Bridge Removal and Wood Placement project was completed on The Nature Conservancy's (TNC) Ellsworth Creek Preserve in Pacific County, WA in October of 2017. 50 engineered logjams were designed to be installed in specific locations for specific purposes over one mile of stream reach on Ellsworth Creek located approximately 3-4 miles upstream of the estuary. One road crossing removal was planned for a log stringer bridge that was approximately 80 years old and spanned Ellsworth Creek in the same stream reach as the logjams. The logjams were designed to restore stream habitat which had been degraded in prior decades from historic "stream cleaning" and logging practices. The log stringer bridge had also degraded stream habitat by straightening and scouring the stream channel. The bridge structure was also beginning to rot and degrade and the foundation logs were becoming undercut. The road approaches to the bridge were also scheduled to be decommissioned and the road prism restored to native gradients A total of 46 of the engineered logjams were built and two additional non-engineered logjams were built from the bridge timbers for a total of 48 channel structure placement using no less than 187 rootwad trees and large cedar timbers. Two of the logjams were not built in the beginning of the project because an effective, operational system was still being developed and the first system of construction would have caused an unacceptable amount of timber felling in the river migration zonewhich was antithetical to TNC's silviculture goals. The design and construction of the logjams secured the trees into the streambanks, stream adjacent trees, and stumps. The design effectively uses the force of the water to strengthen the structural integrity of the logjam and, as of 12/28/2017 all the constructed logjams remain intact and in place. Due to operational efficiencies and other extraneous staffing factors, there was a surplus of funding in the grant. A second log stringer bridge (not a passage barrier) located approximately 600 feet from the first bridge removed was also able to be removed. This bridge was in a similar state of decay and was also contributing to stream straightening and scouring. Along with the bridge removal, TNC was able to decommission the road approaches, and restore native gradients in the vicinity of the second bridge. Work was completed in October 2017.
