USER NOTES:

This dataset is the result of the public review process of the original ecological network model results (GWECO), with areas deleted or added based on changes in landuse, isolation, or additional connected significant ecological features warranting inclusion. Between July 1997 and July 1998 review and comment was conducted using two approaches. Regional Greenways Task Forces reviewed the results and suggested modifications (July 1997 - May 1998) and public hearings were held (October 1997 and June - July 1998) where further modifications were suggested. The Florida Greenways Coordinating Council was asked to review these recommendations and to advise on their appropriateness. Suggested changes to the ecological model results derived from this process were minimal. They included the elimination of a few areas that were no longer suitable for inclusion because of their recent development or isolation from the rest of the network. In central and southeast Florida, there were a few areas suggested for addition to widen and enhance the effectiveness of corridors or to provide additional connectivity. The identified 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:

We recommend that this dataset (instead of the original model results, GWECO) be used as the primary data layer for conservation planning efforts and analysis, but the two datasets, this one and GWECO 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, GWECO is the appropriate dataset 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:

  1. The data does not require or empower any unit of local government, regional government or any state agency to impose additional or more restrictive environmental, land use or zoning regulations.
  2. The data may not be construed or cited as authority to adopt, enforce or amend any environmental regulation or statute, zoning, or land use ordinance or any other rule, regulation or ordinance by any subdivision of local, regional or state government.
  3. The data may not be used as the basis for permit denial; imposition of any permit condition; or application of any rule, regulation or ordinance by any subdivision of local, regional or state government.
  4. Government agencies may not reduce or restrict the rights of private owners as a result of private lands being identified by this data.
  5. No private lands will be considered as designated greenways or trails pursuant to Section 260.018, Florida Statutes, unless the owner of such lands has voluntarily and explicitly agreed in writing to such designation.
  6. The reliability of this data layer is limited by the resolution and timeliness of the underlying data and information.
  7. Identification of named, existing or proposed public lands is solely for planning purposes and not for regulatory purposes. The actual line delineating the boundary of such properties is as designated by the applicable state, federal or regional agency which boundary for all purposes shall take precedence over any mapping as contained herein. Better site-specific data, if available, for any features or resources shown on this map should be used to identify whether any such resources are, in fact, present on that site.

DATA LINEAGE SUMMARY:

This dataset is a modified version of the Ecological Network Results of the Florida Greenways GIS Decision Support Model (represented by the data layer GWECO) based on recommendations from public comment. See the University of Florida Final Report* for the modeling process. Edits made to GWECO consisted of hand-digitized deletions and additions, as well as results from further runs of the linkage process based on recommendations(described in the Final Report*).
