Over the past 40 years, more than 100 tidal marsh restoration projects have been constructed in the Fraser River Estuary to mitigate the loss of habitats from human activities and to maintain the ecological integrity of the area. More projects continue to be proposed. However, reports have shown that the success of these restoration projects varies.
An in-depth report by DUC—the most comprehensive analysis of tidal marsh creation projects in the Fraser River Estuary to date—sheds light on factors that lead to some projects being more successful than others. Among the findings detailed in the report, entitled Factors Influencing the Persistence of Created Tidal Marshes in the Fraser River Estuary:
The Factors Influencing the Persistence of Created Tidal Marshes in the Fraser River Estuary report is the start of a longer investment by DUC over the next two years to restore tidal marshes throughout the estuary to support carbon sequestration and restore salmon habitat. DUC will use the findings from the report to inform restoration works and identify some unsuccessful compensation sites to restore.
The study was funded by the B.C. Wildlife Federation Wetlands Workforce project and supported through the provincial Healthy Watersheds Initiative delivered by the Real Estate Foundation of B.C. and Watersheds B.C. with the financial support from the Province of B.C. as part of its $10 billion COVID-19 response.
