Abstract
The focus of this report was to monitor benthic macroinvertebrate communities on the Freshwater Farms Reserve, which underwent two phases of restoration as part of the Wood Creek Tidal Marsh Enhancement Project in 2009-2010 and 2016-2018. Objectives for the restoration activities were to increase winter rearing refugia habitat for several threatened/endangered fish species such as the tidewater goby (Eucyclogobius newberryi), Coho salmon (Oncorhynchus kisutch) and steelhead trout (Oncorhynchus mykiss). The goals of this project were to (1) sample and identify BMIs along a salinity gradient in Wood Creek; (2) assess water quality; and (3) report general trajectory of community composition over time. Results show that the abundance of benthic macroinvertebrates increased dramatically in Wood Creek in 2019 for all sampled sites when compared to previous years of monitoring data. Three taxa accounted for over 99% of the overall composition at each of the sample sites. Increased abundance of benthic macroinvertebrates may provide additional nutritional support for fish present in Wood Creek and Freshwater Creek. Overall, Freshwater Farms Reserve’s post-restoration ecological trajectory seems to be improving in relation to the goals of supporting fish refugia for threatened/endangered species.
