It is a continuation of projects that have occurred in the Lower Stave River region to improve the overall salmon habitat in the area. This years project aligned with FWCP Action Plans: Stave Salmonid Action Plan, Habitat-based Actions to ensure a productive and diverse aquatic ecosystem and maximize the viability of anadromous salmon (coho, chum and chinook). In addition, this project aligned with FWCP Action Plan: Stave Riparian Wetlands Action Plan, Habitat-based Actions to ensure productive and diverse wetland and riparian ecosystems and reduce threats to Category 1 (natural riparian or wetland habitat largely intact ecosystems with natural disturbances sufficient to maintain subclimax communities and processes characteristic of wetlands and riparian ecosystems). This project resulted in the restoration of the following amount of habitats: • 12,500 m2 newly created off-channel aquatic habitat • 4,375 m2 of riparian and aquatic planting using 13,035 individual native plants. FWCP contributed $78,894.20 from July 2017 to March 31, 2018, and with matching and partner in- kind contributions the total project value of this project $248,200. This report summarizes the results of work completed between July 2017 and March 31, 2018 under the financial contribution of the Fish Wildlife Compensation Program (FWCP). Additional support for this project was received by the National Wetlands Conservation Fund, Department of Fisheries and Oceans Canada Salmon Enhancement Program, Pacific Salmon Foundation, Stave Valley Salmonid Enhancement Society, Coastal Painted Turtle Project, University of the Fraser Valley, Ducks Unlimited Canada, Kwantlen First Nation, District of Mission, the local community members, the Fraser Valley Watersheds Coalition, and the Fraser Valley Regional District. Thanks to the momentum of on-the-ground restoration activities, the strength in partnerships and sponsorships, and overall importance of this project, further restoration efforts and long-term management plans are being developed to continue building upon the success and ensure long-term ecological integrity is maintained.

Introduction and Rationale Tidally influenced freshwater estuaries and off-channel habitats are critical areas benefiting salmon, waterfowl, migratory birds and many mammals, and serves as an important ecosystem for flood protection and human serves. They are vital in maintaining the ecological integrity of river systems in British Columbia. Natural off-channel habitats include beaver ponds, wetlands, alcoves, floodplains, side channels and tributaries. The Lower Stave River has been regarded as one of the most productive salmon habitats in the province and supports the second largest chum salmon population in the Fraser River watershed. The presence of the Ruskin dam restricts the range of habitat that the anadromous salmon can use, and currently only the lower 3 km section of the Stave River provide habitat for these spawning salmon. This project focused on the right bank of the Fraser River, within the Stave River Watershed area, Mission BC. Challenges within this watershed have occurred historically and some are still present today. Extensive wetland loss, rapid development and growth, significant changes to the river hydrology from the construction of the Ruskin Dam, and the potential impacts from nearby industrial and agricultural land uses, and invasive species encroachment into natural habitats. While not all challenges are addressed as part of this project, key habitat-related restoration opportunities at specific locations were pursued. Improved habitat form and function as a result of this projects efforts improved habitat connectivity to support listed SARA species including the Western Painted Turtle, and those species included within the Bird Conservation Strategy – Region 5 (5PY) that require shrub/early successional stages and seral species habitat niches for migration and winter refuge. This may include common nighthawk, MacGillivrays Warbler, Orange Crowned Warbler, Spotted Towhee and/or Willow Flycatcher. In addition, provide habitat values for the non-migratory Lower Fraser Valley Sandhill Cranes, which was de-listed, but has not been assessed since 1979, and this coastal population could be listed as threatened by Committee on the Status of Endangered Wildlife in Canada (COSEWIC) due to it being a Lower Fraser Valley sub-population. In addition, monitoring efforts within this watershed help to complete data knowledge gaps and plan for habitat adaptation and management for long-term success. 3. Objectives and Goals The overarching objective of this project was to enhance sections along the right bank of the Fraser River within the Stave River Watershed to support functional ecological processes, provide suitable habitat conditions for wildlife and fish and build momentum and partnerships for long-term stewardship and conservation of these areas.

Restoration of Habitat: Construct and restore off-channel historical tidal channels and create additional channels in the tidal estuary that have been impacted by invasive species
