Long-Term Monitoring & Research at the Illinois River Biological Station

LTRM & LTEF Monitoring

The biological station is part of two long-term monitoring programs, LTRM and LTEF. Both of these programs have been maintained by biologists at IRBS for decades focusing on fisheries monitoring in both the Illinois and Mississippi Rivers.

The Emiquon Preserve

The Nature Conservancy’s Emiquon Preserve is one of the largest floodplain restoration projects in the United States. IRBS has monitored the aquatic vegetation and fish communities at Emiquon Preserve’s Thompson and Flag lakes since 2007.

Invasive Species Research

The biological station is actively involved in research on invasive carp species in the Illinois River Waterway partnering with multiple state and federal agencies in Illinois and the surrounding states. Several research projects have also been completed on non-native species that have become established in the Illinois River Waterway such as white perch, round goby, and zebra mussels.
