	          ECOCODE: first two digits are the primary ecoregion
		  number. The third digit corresponds to its 
		  alphabetic equivalent.  i.e.  101 = 10A
		                      	        107 = 10G

Ecoregions denote areas of general similarity in ecosystems and 
in the type, quality, and quantity of environmental resources.  
This map depicts revisions of ecoregions, originally compiled at a 
relatively small scale (Omernik, 1987), as well as subregions of 
those ecoregions.  Compilation of this map, performed at the larger 
1:250,000-scale, was part of a collaborative project between the 
United States Environmental Protection Agency Environmental 
Research Laboratory-Corvallis and the Florida Department of Envi-
ronmental Protection. The ecoregions and subregions are designed 
to serve as a spatial framework for environmental resource manage-
ment:  the most immediate needs are for developing regional bio-
logical criteria and water quality standards, and for setting 
management goals for nonpoint-source pollution.  Explanation of 
the methods used to define the ecoregions is given in Omernik 
(in press), Gallant et al., (1989), and Griffith et al., (1994).
