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 Michigan Bog Grasshopper (Appalachia arcana) is designated as a Regional Forest Service Sensitive Species endemic to the state of Michigan. In 2017, timber was harvested in an area of the Mio Ranger District in Huron National Forest with a documented Michigan Bog Grasshopper population, though the impact of management on this species is currently unknown. In 2018, the grasshopper population on the 54-acre plot was studied to determine the impact of management on habitat use and population dynamics of this species. One vegetation plot was conducted per acre (n=54) using a 1 m<sup>2</sup>quadrat to identify available habitat. Measurements collected include height class, horizontal density, and proximal tree species distance from the center of each plot. In the 54 acre survey area, visual encounter surveys were conducted by slowly walking and placing a flag where a grasshopper was observed. After confirming the species and sex of the grasshopper, coordinates were recorded and a vegetation survey was conducted to identify selected habitat (n=103, 67 males and 36 females). This replicated a 2014 study on the same site in which 51 males and 33 females were counted. Although no estimate was produced, comparison with the 2014 data suggests the population has not experienced a decline and the area of usable habitat may have expanded. Michigan Bog Grasshoppers continue to select areas containing sweet fern and dense blueberry understory along with course woody debris. <a name="_Hlk524978184"></a> Composition of vegetation plots yielded strong selection ratios for sweet fern (?<sub>female</sub>=2.18, ?<sub>male</sub>=2.60), course woody debris (?<sub>female</sub>=2.75, ?<sub>male</sub>=2.40), and blueberry (?<sub>female</sub>=1.83, ?<sub>fmale</sub>=2.1).  Although more study is needed, the results suggest timber harvest may not negatively influence Michigan Bog Grasshopper population numbers or alter habitat selection.
