Maple Sugaring: An Introduction to Small-Scale Commercial Production
A Dartmouth College study published in Forest Ecology and Management suggests that by 2100, maple sap may flow a month earlier in some parts of the United States. Over a 6-year period, the study tested how monthly and season-long average temperatures during the tapping season, and temperature and precipitation from the preceding year, affected sap flow in six locations from Virginia to Quebec. Based on the results, the researchers predict that, by 2100, Virginia and Indiana locations will produce hardly any sap and production in other parts of the United States will decline, while Canadian production will improve. “Maple syrup producers may want to consider adapting their technologies and collection logistics in advance, so that they are prepared for how climate change is going to affect production,” said co-author David Lutz.
