Abstract

NSF RAPID grant proposal to sample nutrients, processes (e.g., denitrification), and communities (e.g., microbes and zooplankton) that respond quickly to disturbances at two floodplain restoration sites on the Illinois River that flooded for the first time during the record flood of April 2013. We will also document the longer-term responses of submerged macrophytes and higher level consumers (birds and fishes) using existing data sets and on-going sampling programs.The flood event at one site (Emiquon) approximated a natural seasonal flood because the flood overtopped the levee for a few days but did not breach the levee. In contrast, the levees breached at the other site (Merwin), and river water continues to flood through Merwin. We hypothesize that the restoration trajectory has been reset at Merwin.
