Bus Tour • Thursday, June 9 • 12:00 pm - 8:00 pm
(included in conference fee; registration required)

     You won’t want to miss this tour featuring one of North America’s premier inland field stations – the W.K. Kellogg Biological Station (KBS). KBS is Michigan State University’s largest off-campus education complex, located between Kalamazoo and Battle Creek, Michigan.

World renowned for its contributions to ecological science and evolutionary biology, KBS is home to the National Science Foundation’s only agriculture-based Long-Term Ecological Research (LTER) site, a brand-new Long-Term Agroecological Site (LTAR) funded by USDA-ARS, and a Great Lakes Bioenergy Research Center site funded by DOE. It is also home to the W.K. Kellogg Farm which includes a grazing dairy with all supporting field crops and research projects including pasture and alfalfa management, malt barley evaluations, cover crop management in corn, soy, and wheat, and much more.

The tour will begin with a box lunch as we embark on our 75-minute ride from the hotel to KBS. Following the tour stops, we will enjoy dinner at the KBS educational campus prior to returning to the hotel around 8 pm.
