Current (2010) conservation prioritization of existing tidal marsh habitat in California's San Francisco Bay estuary. The prioritization is based upon distribution and abundance models for five tidal marsh bird species which utilized avian observation data (2000 - 2009), a marsh accretion model, and physical variables (e.g. salinity, distance to nearest channel, slope, etc). Values represent the rank in which pixels were removed from the landscape using Zonation Conservation Planning software with core area zonation algorithm. Higher values indicate pixels that were removed last and are of the highest conservation value. See http://data.prbo.org/apps/sfbslr/sfbslrapp for interactive maps and additional details.
