SOUTHEASTERN ECOLOGICAL FRAMEWORK PROJECT DOCUMENTATION

REGION 4 CUMULATIVE SIGNIFICANT ECOLOGICAL AREAS

GEODATASET NAME(s): 	seax
GEODATASET TYPE:  	grid
GEODATASET FEATURE: 	polygon

GENERAL DESCRIPTION:

This dataset is a cumulative Significant Ecological Areas (SEA) grid (containing the areas that are common to all of the individual SEA layers) after excluding urban land uses and intensive agricultural lands, high road density (greater than 3 miles/square mile), areas within 270 meters of urban land uses, and areas with high densities of urban land uses. For a list of all SEA data layers, see "Feature Attribute Tables Codes and Values" below.

USER NOTES:

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 In addition, this data is based on land use information that, by its nature, is outdated.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.
