Abstract
Large woody debris (LWD) contribute to the formation of complex habitat structures by stabilizing channels, creating refugia, and enhancing spawning conditions. A lack of LWD in the South Fork Elk River in Headwaters Forest Reserve has been identified by the BLM as a limiting factor in salmonid resurgence. Salmonids provide vital ecological functions to their watersheds; however, their populations face the pressure of habitat loss. This study expands upon last year’s assessment of wood jam formation on the South Fork Elk River and examines how log jam structures have changed over time since the BLM’s 2022 accelerated recruitment project. This year’s assessment found limited change in LWD presence and structure on the South Fork Elk River since last year, with a similar number of single pieces and the same number of jams being recorded. Continued monitoring and more in-depth analyses of LWD characteristics between continuing monitoring years may provide more insight into the long-term changes in jam formation and aid the assessment of salmonid habitat restoration.
