Overall, the sap was sweet but didn't flow all that much
Harvard Forest Post-Doctoral Researcher
Sugar maples are economically important in the northeastern U.S. and adjacent Canada because of maple syrup production, and concerns exist about the viability of maple populations and the maple syrup industry under a warming climate. I am collecting long term records on sap flow and sap sugar content from across New England to understand if these records reflect the resource status of trees and whether this is correlated with variation in seed production across years. This regional study is complemented by detailed observations of sap production, flower and seed production, and pollinator populations at the Harvard Forest to investigate how stored resources and pollination limitation influence masting in sugar maple.
