Welcome to the interactive web schedule for the 2019 Midwest Fish & Wildlife Conference! The schedule is subject to change (as of November 20, 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

(WILDLIFE: WETLAND CONSERVATION) The Influence of Impoundment Management on Whooping and Sandhill Crane Colt Survival at Necedah NWR

AUTHORS: Ross P. McLean, University of Wisconsin-Stevens Point ABSTRACT: Whooping Cranes (WHCR) are federally endangered and in 2001, a reintroduction effort was initiated at Necedah National Wildlife Refuge (NNWR) in Wisconsin to establish an Eastern Migratory Population (EMP). However, despite seventeen years of management, recruitment remains low.  Greater Sandhill Cranes (SACR, Antigone canadensis tabida) are biologically similar to WHCRs and have similar breeding ecology.  We studied colt survival for both crane species at NNWR to determine if low recruitment is unique to the Eastern Migratory Population (EMP) of WHCRs, or an issue for both North American crane species in the initial introductory breeding grounds of the EMP. Additionally, we lowered water levels in some wetland impoundments to better mimic the natural annual water cycle. This management action was part of an effort to increase wetland and forage access for wading birds during summer months. Our objectives were to determine (1) if summer drawdowns and reduced wetland water levels increase survival of WHCR and SACR colts compared to cranes reared in or near impoundments with full water levels, and (2) differences in overall colt survival rates between species. We hypothesized that (1) WHCR would use the drawdown areas more than available wetlands with higher water levels, and (2) that colt survival would be higher in lower water wetlands due to increased mobility and access to prey. We placed VHF transmitters on adults and colts of both species to collect colt survival status and family group locations every day during the 2017-2018 field seasons. Analyses are ongoing, but many of the fledged colts were raised in areas with lower water. We will discuss implications for crane management in the Midwest.     <a href="applewebdata://63650BC7-DDE7-47CB-BF71-58A32F69113E#_msoanchor_1"></a>
