Abstract
In 1984, a Biological Stream Characterization (BSC) Work Group convened to develop a multi-tiered classification of streams based primarily on fish communities. The use of letter grades "A" through "E" for evaluated reaches established a means of communicating levels of biotic integrity to 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 BSS process expanded on BSC "A" rated streams by adding additional information on endangered and threatened species and mussel diversity.
The resource includes access to a stream rating report ("Integrating Multiple Taxa in a Biological Stream Rating System"), a mapping tool, and stream rating data.
