DESCRIPT   Based on VALUE item description.


Ecological Model results as modified by public comment were reviewed by private landowners in public forums and in arranged individual meetings. Since the greenways program is intended to be voluntary and not regulatory, as described in Section 260.0141, Florida Statutes, the FDEP agreed to develop a third product of the planning process that would remove lands from inclusion within the ecological and trails results when so requested by the land owner. Approximately 60 landowners requested the removal of their lands, and these modified results reflect the removal of lands owned by landowners who requested removal and provided appropriate maps or digital data to sufficiently indicate their property boundaries.

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: 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.

However, this dataset has been affected by the removal of lands based on landowner requests. Therefore, parts of the Ecological Network model results connected in GWECO or GWECOP may no longer include connections and could be completely isolated due to the vagaries of removal based solely on landowner request. No attempt has been made in this dataset to redesign the Ecological Network based on the impacts of the removal of these properties.

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.

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.

This dataset is a further modified version of the Ecological Results of the Florida Greenways GIS Decision Support Model (GWECO) as Modified by Public Comment (represented by the data layer GWECOP) based on recommendations from landowner comment. See the University of Florida Final Report* for the modeling process. Land areas delineated by hard copy maps (digitized by GeoPlan) and digital maps received from Florida landowners were removed from the GWECOP to create this dataset.
