Description    


Juvenile Coho Salmon abundance was measured for a before-after, control- impact (BACI) analysis of restoration effectiveness. Analyses evaluated the effectiveness of Phase I habitat restoration at increasing Coho Salmon abundance. These analyses include three years of pre-treatment and three years of post-treatment monitoring data for each monitoring metric. The resulting report includes Juvenile Reach Level Abundance Estimates, Pre- and Post-Treatment Comparison of Reach-Scale Abundance (T-tests), BACI Models to Test for Treatment Effects, and Production of juvenile Coho Salmon estimated for: (1) the watershed upstream of the upper trap, and (2) the watershed upstream of the lower trap. Seasonal patterns of juvenile Coho Salmon movement, growth, residence time, and survival within the project reach were compared across years to assess whether these variables were influenced by implementation of Phase I restoration.

Project Benefit    


Evaluate the benefits of recently constructed restoration sites on juvenile coho salmon populations and inform future restoration site designs based on monitoring results. The effectiveness of restoration sites at increasing juvenile coho salmon abundance will be evaluated at multiple spatial scales, including the Project Reach, sub-reach, and site-specific scales. This information will allow for future restoration to be designed in a way that maximizes benefits to coho salmon populations.
