Abstract |
We have defined ecological regions of Tennessee at two hierarchical levels that are consistent and compatible with the U.S. EPA ecoregion framework, Eight level III ecoregions and twenty-five level IV ecoregions have been mapped for Tennessee. A multi-agency cooperative effort also resulted in the identification of potential stream reference sites within the Tennessee ecoregions. Streams that are representative of the ecoregion and are minimally disturbed and least impacted from point and non-point source pollution can serve as suitable reference streams. The ecoregions and reference sites can be used to better understand regional variations in stream quality, assess attainable conditions, develop biological criteria, and augment the watershed management approach. |
