Scientists take a historical look at fishes of Champaign County streams

Read the full story from the Prairie Research Institute.

Using data spanning 120 years, scientists in the Illinois Natural History Survey (INHS) have a unique view of long-term changes in stream fish populations and their habitats in Champaign County. The best news: several fish species that were last seen here in the 1960s have returned to the county, suggesting some streams are improving.

Champaign County fish surveys were first taken in the late 1880s, with subsequent monitoring in 1930, 1960, and 1988. INHS ecologists resampled 122 sites in the county between 2012 and 2015.
