A controlled burn flashes across a grassland research area at Merry Lea Environmental Learning Center on Monday. Ryan Sensenig, assistant professor of biology, has been studying the grazing habits of deer in the plot. Since grassland areas burn every three to four years, it was decided to conduct a controlled burn of the research plot. Aaron Goldstein, Jeremy Good and Darin Schwartzentruber were among the students from an environmental science class taught by Sensenig who assisted with the burn. Photo contributed by Ryan Sensenig.
