Status: 
Ongoing
Science Themes: 
Maple syrup is produced from the sap of sugar maple trees collected in the late winter and early spring. Native American tribes have collected and boiled down sap for centuries, and the tapping of maple trees is a cultural touchstone for many people in the northeast and Midwest. Because the tapping season is dependent on weather conditions, there is concern about the sustainability of maple sugaring as climate changes throughout the region. In spite of this, maple syrup production is increasing rapidly, with demand rising as more people appreciate this natural sweetener. 
 
This research project addresses the impact of climate on the quality of maple sap used to make maple syrup. Informed by the needs of state and federal resource managers, tribal groups, and other maple syrup producers, the research team will examine the chemical composition of sap collected throughout the northeast and relate this to variation in climate across the region. They will also examine sap from red maple trees, an alternative to sugar maple that is increasingly used to make syrup, and a tree species that is expected to be less sensitive to climate change. Ultimately this project will make projections of maple syrup quality under future climate conditions and under a variety of management strategies.
