Sedimentation of the Illinois River in central Illinois has greatly diminished the utility and ecological value of the Peoria Lakes reach of the river. Consequently, a large dredging project has been proposed to improve its wildlife habitat and recreation potential, but disposal of the dredged sediment presents a challenge. Land placement is an attractive(More)
Dredging sediments from water bodies in Illinois is done to preserve reservoir capacity, maintain navigation and recreation channels, and restore habitats, but the fate of the sediments is an issue. In anticipation of a major sediment dredging operation in Lake Peoria in the Illinois River, a retrospective study of sediment placement operations was(More)
Using historic data sets, we quantified the degree to which global change over 120 years disrupted plant-pollinator interactions in a temperate forest understory community in Illinois, USA. We found degradation of interaction network structure and function and extirpation of 50% of bee species. Network changes can be attributed to shifts in forb and bee(More)
The overall habitat quality of the Illinois River is significantly degraded by over 100 years of sediment accumulation. Once-deep backwaters and side channels have lost well over 70 percent of their water storage capacity and in many areas average about a foot deep. A twenty-year restoration project by the State of Illinois and Army Corps of Engineers is(More)

The authors wish to acknowledge the assistance of John C. Marlin (ISTC) for making sediment analysis data available for this report, providing text on the river and sample collection and preparation, and assisting with editing. The sediment cores and data were collected over several years as part of several projects collectively referred to as the Illinois(More)
