FLORIDA GEOGRAPHIC DATA LIBRARY DOCUMENTATION
VERSION 2005
TITLE: GREENWAYS PROJECT PRIORITY ECOLOGICAL AREAS (AFTER EXCLUSION)
Geodataset Name: GWPEAX Geodataset Type: Grid Geodataset Feature: Polygon
GENERAL DESCRIPTION:
This dataset contains Priority Ecological Areas (PEAs) after the removal (exclusion) of incompatible areas. PEAs are ecological features and conservation designations that were given the highest priority for inclusion and physical linkage in the Ecological Network.

USER NOTES:
This dataset contains Priority Ecological Areas (PEAs) after the removal (exclusion) of incompatible areas. PEAs are ecological features and conservation designations that were given the highest priority for inclusion and physical linkage in the Ecological Network. However, not all PEAs were included in the Ecological Network model results. Therefore, this dataset can be utilized in statewide, regional, and local conservation planning efforts as an additional general guide to features of potential ecological significance. For a detailed description of the data used, analytical methods, and modeling process, see: The Florida Greenways Project Final Report, Phase II, Carr, Margaret H., Paul D. Zwick, Thomas S. Hoctor and Mark A. Benedict. Departments of Landscape Architecture, Urban and Regional Planning, and Wildlife Ecology and Conservation, University of Florida. A digital version of this report in pdf format should be available on the web at www.geoplan.ufl.edu by June, 1999.
It should also be considered that this dataset is at a resolution of 180 meters (180 m X 180 m cells), which is approximately 8 acre squares. Therefore, users should not expect great accuracy at high resolutions. The modeling and identification effort 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 In addition, this data is based on land use information that, by its nature, is outdated. An effort was made to update land use data provided by the Water Management Districts, mostly completed in 1990, by comparing this data with 1994-1995 SPOT 10 meter resolution imagery. All areas that appeared to be converted to development (residential, commercial, industrial but not including conversion to intensive agriculture)were added to avoid identifying areas as ecologically significant that are now developed. However, 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.
Pursuant to Chapter 260.0141 Florida Statutes: The Opportunities as illustrated by this data layer are intended to establish an informational framework for voluntary participation by citizens, private property owners and all levels of government subject to the following limitations:
