Climate change-induced sea level rise is expected to impact the lower Columbia River and estuary in a number of ways. Because of the extensive loss of tidal wetlands that has already occurred over the last century due to other, more direct human activity, one of the biggest habitat threats that sea level rise presents is the loss of additional tidal wetland areas as a result of increased tidal inundation. These wetlands provide critical habitat for numerous species, including critically endangered and threatened juvenile salmonid species. The Estuary Partnership recently completed a baseline
