Aquatic Vegetation and Fish Community Monitoring
at The Nature Conservancy’s Emiquon Nature
Preserve
• River and floodplain interaction essential
• maintains river integrity
• ex. ecological, geomorphological, hydrological
• Floodplains
• maintain biodiversity
• provide ecosystem services
• ex. ecological and societal benefits
Floodplain Importance

Floodplain Restoration
• Illinois River is a productive, floodplain river system
• among highest commercial fishing harvest rates historically
• natural biological productivity changed
• ex. floodplain disconnection, elevated nutrient inputs, and invasive fish species
• The Nature Conservancy’s Emiquon Preserve
• intended to benefit Illinois River
• serve as model floodplain restoration
Restoration Evaluation
• Illinois Natural History Survey
• standardized monitoring
• fish (2007-present) (Gutreuter et al. 1995)
• aquatic vegetation (2008-present) (Yin et al. 2000)
