This map represents a potential Conservation Target (CT) for PFLCC's 'Pine Flatwoods and Dry Prairie' (PFDP) Priority Resource (PR). The potential CT is 'Open Pine Bird Index.'The birds included in this index are: Bachman's Sparrow, Northern Bobwhite, and Red-cockaded Woodpecker. These layers were created for an initial investigation of potential CT's suggested by stakeholders during brainstorming workshops. The initial investigation entails locating available datasets to address the suggested CT as closely as possible and performing minimal analyses to determine their usefulness. The final set of CT's and their associated datasets will be chosen after targets (e.g., endpoints) are established as a threshold for achieving a conservation success for that CT.
For a description of the priority resource layer, see the PFDP Priority Resource layer found in this gallery.
There were two sources for data layers available for the included bird species. FWC developed predicted habitat for the Red-cockaded Woodpeckers as part of the 'Wildlife Conservation Habitat Needs in Florida' (2009), however predicted habitat for Bachman's Sparrows and Northern Bobwhites were not part of that project. So for consistency, all predicted distributions were taken from the Southeast Gap Analysis vertebrate modeling.
These models predicted distributions were developed for the SE-GAP distribution modelingusing composition and structure of dominant vegetation along with additional ancillary data, within the species known range. Ranges were determined using NatureServe data. Details for each of these models can be found at SE-GAP websites: Bachman's Sparrow , Northern Bobwhiteand Red-cockaded Woodpeckers. Because both FWC and SE-GAP produced models for Red-cockaded Woodpeckers, the models could be compared. FWC predicted distributions are greatly refined, compared to that of SE-GAP. SE-GAP uses coarser methods and data and so produces habitat models with a wide range of potential for the species.
SE-GAP models were reprojected to a custom projection to match the priority resource layer. The resolution of the models, 30-m, is coarser than that of the priority resource and so areas will not be accurately reflected. The models were combined to determine areas of co-occurrence and then masked using the PFDP priority resource raster to extract pixels from the combined distributions. For preliminary summaries of the extracted values, see also the 'Pine Flatwoods and Dry Prairie’ webinar (in pdf form) located within this gallery.
This map contains two layers. One is the combined predicted distribution models within Florida and the other is the extracted combined distribution for the PFDP priority resource.
