USER NOTES:

Priority Ecological Areas (PEAs) are the primary building blocks of the Southeastern Ecological Framework (SEF). In the SEF delineation process, 24 PEAs were identified. (See Final Report Southeastern Ecological Framework, Table II-I for complete list of PEAs). This dataset represents all PEAs identified for the delineation of the SEF, after excluding unsuitable land uses that overlap with these areas. Areas within this dataset with a value = 1 are identified as one of the 24 PEA criterion.

The Southeastern Ecological Network integrates and connects existing conservation areas and currently unprotected areas of high ecological significance, and this information can be used in concert with other information on conservation priorities to develop a more integrated regional landscape protection strategy. For a detailed description of the data used, analytical methods, and modeling process, see: "Final Report Southeastern Ecological Framework". A digital version of this report in pdf format is be available on the web at www.geoplan.ufl.edu/epa.

Please note that this dataset is the unmodified results of the model before review by other scientists and conservationists.

It should also be considered that this dataset is at a resolution of 90 meters (90 m X 90 m cells), which is approximately 2 acre squares. Therefore, users should not expect great accuracy at high resolutions. The modeling and identification efforts of a statewide ecological network is intended to serve as a general basis for state level conservation planning. It may serve as an adequate framework or guide for regional and local conservation planning efforts, but it should be supplemented by more resolute datasets and analyses especially at the local level. The conservation/land protection process should also always include ground-truthing to evaluate sites in the field. In addition, this data is based on land use information that, by its nature, is outdated. It should be obvious that development continues at a rapid pace, and areas identified in the model results could now be converted to intensive land uses or could be converted in the near future.
