The maps show priority areas for conservation of tidal marsh birds given current and future environmental conditions. Maps were created using Zonation, a spatial conservation planning software tool that can take into account multiple species and scenarios to create a hierarchical prioritization of the landscape. |

Why use this tool for Conservation Planning?
- The models generating these maps are the first to take into account the ability of marshes to accrete, or keep up with, rising sea levels, in the San Francisco Bay Estuary.
- PRBO has generated a series of scenarios to provide a range of projections to address the uncertainty in future rates of sea-level rise and suspended sediment availability.
- Our maps cover the entire Estuary allowing for analyses at multiple spatial scales.
- This tool displays maps created at a high spatial resolution using the best available elevation data. The website will be continually updated as new data becomes available
- The tool is the first to provide spatially explicit projections of vegetation and bird distributions throughout the Estuary
The PRBO Sea-Level Rise Tool will help you:
- View and query maps to understand how sea level rise may change the extent of tidal marsh habitat and bird species distribution over the next 100 years
- Make informed decisions about adaptation planning, restoration potential, and land acquisition given various sea-level rise and sedimentation scenarios.
- Identify areas both vulnerable and resilient to future sea-level rise.

Publications
We have published the results of our marsh accretion modeling in PLoS ONE.
We present the methods and results of our conservation prioritization and modeling of tidal marsh bird and vegetation response to sea level rise in a technical report to the CA State Coastal Conservancy.
