John (Mac) Marston, PhD, is a specialist in paleoethnobotany, the study of archaeological plant remains. He has been burning wood samples from the Arnold Arboretum to create a reference collection of charcoal for archaeological field research. In this tree mob, he will explain how archaeologists use small fragments of ancient, burned wood to understand environmental change and describe some of the results from his collaborative work in central Turkey that show long-term human impacts on forests. Gather in the Conifer Collection at 6pm on Thursday, May 21 at Juniperus excelsa Acc. # 17-2003*C.
