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

(SYMPOSIA-06) How Do Beavers Affect Trout Populations? Well, it depends…

AUTHORS: Troy Zorn, Michigan Department of Natural Resources Fisheries Division

ABSTRACT: Most published studies do not provide a complete understanding of the effects of beavers on trout populations and streams.  Results often vary by location, with some studies characterizing beavers as beneficial to trout populations and others indicating beavers are harmful.  Drawing on case studies throughout the Midwest and North America, I will attempt to explain what underlies these seemingly contradictory findings.  For example, groundwater availability and inputs drive many Midwestern trout streams, and a thorough understanding of these processes is critical for understanding how beaver dams will affect trout populations.  Understanding the factors that shape trout streams in other regions will provide the context needed for interpreting an array of studies examining beaver-trout relationships and will enable managers to better predict how beavers might affect trout streams in their region.
