Abstract

Since 2007, the Emiquon Preserve (Emiquon) has been monitored using Key Ecological Attributes (KEA) to determine the success of restoration on the vegetation and fish communities. The KEA’s were developed to reflect a high-functioning, balanced ecosystem at its upper limits. Native submersed aquatic vegetation (SAV) abundance and richness continue to be the dominant macrophyte communities. Submersed aquatic vegetation species diversity has remained stable though the years with native species dominating the biomass. The Emiquon Preserve’s fish community continues to be dominated by native fish species. 2020 saw an increase in abundance of bluegill, bowfin, largemouth bass, yellow bass, and golden shiners from the previous year. An extended drawdown was conducted in 2020 bringing the water surface elevation down to 427.56 ft.
