ADV - Lunch with a Scientist - Bison Project - Cedar Creek
East Bethel, MN 55005
Join life-long learners for a monthly lunch and learn series at Cedar Creek. Bring your own lunch and hunger for knowledge, we will provide the brain food! If weather permits, we will go outside to see the research in action. Please wear closed-toe shoes and dress for the weather. Oak savanna is one of Minnesota’s most threatened ecosystems. Today, less than 0.1% of savanna remains, and most have lost their native grasses and wildflowers as the lack of fire allows trees to dominate. Savanna restoration research at Cedar Creek started in 1965 and has shown fire eliminates non-savanna species and restores savanna species. This has also shown frequent fires prevent oaks from regenerating. Grazing by large herbivores may be essential for restoration and preservation. When not grazed, grasses compete with oak seedlings and, when these ungrazed grasses burn, their high abundance causes intense fires that kill oak seedlings. By introducing bison we hope to better understand how we might preserve Minnesota’s oak savannas long into the future. Chad is a postdoctoral associate working with Forest Isbell and Dave Tilman on the bison and savanna research project. His research asks if grazing by bison reduces fire intensity and competition from dominant grasses to promote oak regeneration and the diversity of savanna species. Chad completed his Ph.D. at Michigan State University where his research aimed to understand how plant functional traits structure the community assembly and functioning of ecosystems undergoing restoration.
