Appendix O. Ecoregional Reference Reach Program Lead agency: ADEM Purpose: Ecoregions are relatively homogeneous ecological areas defined by similarity of climate, landform, soil, potential natural vegetation, hydrology, or other ecologically relevant variables. Since 1991, ADEM has maintained a network of least-impaired ecoregional reference reaches. Intensive monitoring assessments, including chemical, physical, habitat, and biological data, are collected to develop baseline reference conditions for each of Alabama’s 29 Level IV subecoregions (Grifith et al. 2001). The reference condition establishes the basis for making comparisons and detecting use impairment. Appendix O-1. Habitat assessment data Appendix O-2. Biological assessment data Appendix O-3. Physical/ chemical data References: ADEM. 2002k. Ecoregional reference reach data collected by ADEM 1992 to 2002 (unpublished).
