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.
The current (2010) and future (2030-2110) 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.
This dataset has been updated and is superseded by a newer version. Please see http://data.prbo.org/apps/sfbslr/sfbslrapp (link is external) for interactive maps and additional details.
