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.

TIPS FOR NAVIGATING THIS SCHEDULE:
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: The overall population of bald eagles (Haliaeetus leucocephalus) has increased in range and size across much of North America, since they were listed as a federally Threatened Species in the 1970’s.  This increase likely is due in part to the efforts of several federal and state wildlife management agencies in protecting nest sites, an important factor in raptor reproduction.  We studied nest-site selection in bald eagles along the 420-km long Upper Mississippi River National Wildlife and Fish Refuge using survey data from 1990 – 2012.  Spatial analyses were conducted on known active nest locations using a GIS to develop several metrics relating to bald eagle nesting ecology (e.g., distance to water, surrounding cover type, patch size) and several disturbance metrics (e.g., distance to navigable channel, distance to road).  These metrics will then be used to build a mixed-effects resource selection function under a use-availability design for this population.  This information will increase the understanding of how bald eagles occupy habitats along the Upper Mississippi River in relation to habitat features and human activities, further contributing to the effective management of this species.
