Description    


This project will implement construction of beaver dam analogs (BDAs) on Reservation tributaries to the mainstem Trinity River including Tish Tang, Campbell and Soctish creeks, which are identified as having high Intrinsic Potential for Coho salmon. Previous funding from PCSRF is supporting construction of BDAs on Mill and Supply creeks. As identified in the SONCC Recovery Plan, complex aquatic habitats, including beaver ponds, within tributaries of the lower Trinity River represent limited and high-value habitat for Coho salmon juveniles as they grow to the outmigrant/smolt lifestage. The SONCC Recovery Plan also highlighted the importance of reestablishing beavers in streams where they are absent. BDSs serve two purposes related to Coho recovery - they provide immediate habitat complexity while expanding useable habitat availability through low-flow periods, and they provide habitat for dispersing or relocated beavers. Beaver dam analogs are wooden post-lines that are driven across the bankfull-width of a stream on 2-3 foot centers, with willows woven between them to a height 2-3 feet above the channel bed; and partially sealed with fine vegetation, mud and cobbles. They are porous structures that do no inhibit juvenile fish movement, and are low enough that they do not pose a barrier to adult fish during spawning migrations. A total of fifteen BDAs will be placed in suitable reaches of the above-named streams. Coho have been documented in all of these streams through field data collection efforts over the past thirty years.

Project Activities and Methods: The Hoopa Valley Tribal Fisheries Department will staff the project with a combination of Senior Hydrologist, Fisheries Biologist, Riparian Ecologist, plus three Fisheries Technicians. Together the team will identify suitable areas to install beaver dam analogs and then construct BDSs according tothe methods described in Pollock et al. The BDAs will be inspected after high-flow events through May 2019, and any components that are removed by high flows will be repaired.

Project Benefit    


SONCC in the lower Trinity River are identified in the Recover Plan as being at high risk of extinction. Restoration of tributary habitat for both natal and non-natal SONCC is therefore of great importance. Ponds and backwater habitats that form upstream of beaver dams were identified in the SONCC recovery plan as high-quality summer and winter rearing habitat for Coho salmon, and so this project is expected to suport increases in survival and growth of Coho as well as the other native anadromous salmonids. Beavers are expected to occupy some or all of the BDAs, and when doing so will sustain and enhance the features.

Therefore, long-lasting ecological benefits are anticipated. Besides the direct habitat benefit to Coho, beaver dams and BDAs can enhance aquatic and riparian functions. Some of these functions are: sequestering of fine sediment until high flows can transport them to floodplains or downstream reaches, recharge of groundwater in adjacent floodplains, increasing hyporheic flows, raising of water tables that support native riparian vegetation, and helping to sustain flows during drought periods. These functions in turn benefit Coho, other aquatic species and terrestrial species that use the riparian corridor.
