TITLE: FDEP ECOLOGICAL REGIONS

Geodataset Name:      ECOREG
Geodataset Type:      Shape
Geodataset Feature:   Polygon

GENERAL DESCRIPTION

Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. The Florida ecoregion map depicts revisions of ecoregions, compiled originally at a relatively small scale (US EPA 1995, Omernik 1987), as well as subregions of those ecoregions.

USER NOTES:

Compilation of the Florida ecoregion map was part of a collaborative project between the United States Environmental Protection Agency (EPA) National Health and Environmental Effects Research Laboratory (NHEERL) - Corvallis, OR., and the Florida Department of Environmental Protection. The ecoregions and subregions are designed to serve as a spatial framework for environmental resource management. The most immediate uses by the State of Florida are for developing regional biological criteria and water quality standards, and for setting management goals for non point-source pollution.
