The most significant differences among the past and present rating systems are:
This revised process incorporates biological data from 1997 through 2007. The IL Department of Natural Resources - Office of Resource Conservation, in partnership with INHS, initiated a project to combine, update, and enhance the two previous approaches for rating Illinois streams. As Illinois resource managers move forward with implementing the Wildlife Action Plan, current stream ratings generated with diverse aquatic biological information and a process by which ratings can be updated were needed. The BSS process expanded on BSC "A" rated streams by adding additional information on endangered and threatened species and mussel diversity.ĭespite the lack of regular updates, both BSC and BSS processes generated products that are used extensively by diverse stakeholders. In 1992, the Illinois Natural History Survey (INHS) published a list of biologically significant streams (BSS) for the purpose of conserving biodiversity across the state. The use of letter grades "A" through "E" for evaluated reaches established a means of communicating levels of biotic integrity to diverse stakeholders. In 1984, a Biological Stream Characterization (BSC) Work Group convened to develop a multi-tiered classification of streams based primarily on fish communities.
