Stream Bioregions

 

Stream Bioregions of FloridaU.S. EPA (1992) defines ecoregions and subecoregions as areas "within which there is an apparent homogeneity in a combination of geographic characteristics that are likely to be associated with resource quality, quantity, and type of stresses."   Regionalization was performed as a collaboration among FDEP, the Florida Water Management Districts, and the U.S. EPA Environmental Research Laboratory in Corvallis, Oregon.

The main issue for the evaluation of bioassessment data was to establish regional reference conditions for ecosystem health through a selection of subecoregional sites.   To determine a subecoregional reference condition, sites were selected on least-disturbed streams with small catchments and completely within subecoregions.   Using this process, over 100 subecoregional reference sites were originally selected by U.S. EPA.  Subecoregions are aggregated  into bioregions based on similarities in their macroinvertebrate communities.   Bioregions are then used as the geographical basis for the assignation of community health thresholds.  Bioregions can be viewed on the map below.
