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 In addition, this data is based on land use information that, by its nature, is outdated.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:
This data layer reflects private lands data received by the University of Florida GeoPlan Center as of December 31, 1998.
Establishment of the Greenways and Trails System is a dynamic process. The Department of Environmental Protection (DEP) and the Florida Greenways Coordinating Council (FGCC) have made every effort to work with private landowners and public land managers to assure them the Statewide Greenways and Trails Program is voluntary. As a result, DEP and the FGCC agreed to remove conservation/ecological features from this map if they occur within the ownership of those who do not wish to have their lands included. Therefore, the Conservation/Ecological Opportunities included in this data layer do not represent a complete statewide vision. This data layer represents a vision as modified by requests from landowners to remove or include their lands in the system.
Some of the Implementation Opportunities in the Southwest DEP District occur in areas being actively mined for phosphate or for which mining is planned. These mining activities are subject to numerous regulatory requirements within the overall mining/ reclamation approval process that may or may not result in lands suitable for inclusion in the greenways and trails system. Designation of phosphate lands as part of the statewide system shall occur only if agreed to by the landowner/mining company and DEP.
Additional lands, particularly in the Northeast region of the state, have been requested to be removed from future depictions of the statewide system. The Department of Environmental Protection will make every effort to obtain the data and boundary information necessary to honor these requests.
