USER NOTES:
The 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: 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.
This dataset is the unmodified results of the model before review by other scientists and conservationists. We recommend that GWECOP, the model results after public review, be the primary data layer used for conservation planning efforts and analysis, but the two datasets, this one and GWECOP can be compared to see what areas were added or deleted through the public review process. However, if the unmodified model results are more apt for your purposes, this dataset is the one to use.
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 In addition, this data is based on land use information that, by its nature, is outdated.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:
