Restoration is essential to recover endangered species, support commercial and recreationally important fisheries, and restore injured natural resources. Urban watersheds are one of the most challenging places to conduct habitat restoration as the work is complicated and expensive.Through our recent habitat restoration efforts in the heavily-urbanized Lower Duwamish River in Washington, we have identified lessons and solutions that may help future urban estuary restoration.We recently sponsored a workshop on lessons learned from these restoration efforts and published the findings in a report. It has valuable information on topics ranging from planning and permitting to post construction challenges. We hope these lessons will apply to various other urban estuaries around the county.
