The Future San Francisco Bay Tidal Marshes Climate Smart Planning Tool is a web application that enables the user to view and query maps made with projected tidal marsh elevations, vegetation changes, five tidal marsh-dependent bird species distribution probabilities and densities, and current and future conservation prioritization. The map-making tool presents the user with current and future maps side by side, and allows for choices of higher and lower levels of sea level rise, sediment availability, and organic material accumulation. The purpose for using the tool is to support an understanding of how sea level rise may change the extent of tidal marsh habitat and bird species distribution over the next 100 years, support informed decisions about adaptation planning, restoration potential, and land acquisition given various sea-level rise and sedimentation scenarios, and to help identify areas both vulnerable and resilient to future sea-level rise.
