Welcome to the interactive web schedule for the 2019 Midwest Fish & Wildlife Conference! The schedule is subject to change (as of November 7, 2018). Please check back for updates. To return to the main Conference website, go to: www.midwestfw.org.

The conference schedule is hosted in SCHED which allows you to search within the schedule, and filter the schedule to show items only occurring on a certain date or within a track/symposia.
  • To view only a certain type of presentation or track, locate the heading "Filter By Type" in the navigation bar. As an example, try clicking on "T01: Fisheries: Great Lakes I".
  • The default view for the schedule is "Simple" which only shows the start time and title of the agenda item. Hover over the button that says "Schedule" to see the different view options. The "Expanded" option will show start and end times, room location, and session description, if there is one.
  • You can build your own schedule by creating a free account with SCHED by selecting "SIGN UP." Watch the "how-to" video to learn more about using Sched. 
  • PLEASE NOTE: Adding agenda items to your schedule through this app does not sign you up for a session. If an agenda item says "pre-registration required" or charges an additional fee, you need to add the item to your registration through the online registration system

ABSTRACT. Having directly restored, enhanced, and protected greater than 2,700 ha of former floodplain wetlands and associated uplands in the central Illinois River valley, the Nature Conservancy’s Emiquon Preserve is the most substantial floodplain restoration effort in the region to date. The restoration has provided critical nesting habitat for many waterbird species, including species of conservation concern such as Least Bittern, Black-Crowned Night Heron, and Common Gallinule. Since 2013, Forbes Biological Station has conducted nest searches in two distinct wetland vegetation communities, dense emergent and hemi-marsh vegetation. We evaluated nest density, nest success, and nest characteristics of marsh birds during June and July of each year. Nest searches were performed in random plots (0.2 ha) that were generated in ArcGIS and we also found nests incidentally when travelling between plots The addition of a water control structure in summer 2016 increased water management capabilities at Emiquon Preserve and restored river floodplain connectivity. In 2018 managers implemented a drawdown designed to restore moist soil vegetation and provide opportunity to perform levee repairs and this allowed us a unique opportunity to evaluate the effects of the drawdown on waterbird nesting ecology. We will compare data from summer 2018 with all previous monitoring years and compare estimates and characteristics of nest density and survival. This may provide valuable insight into how small habitat manipulations can have a large impact on marshbird breeding strategies. This multi-year research project will continue to provide information to adaptively manage and improve Emiquon Preserve and areas like it using nesting waterbirds as an environmental indicator and sentinel of wetland quality.
