Dr. Tim Perkins (Director-University of Vermont Proctor Maple Research Center) discusses the intimate relationship between weather and maple sap flow, changing climatic conditions have the potential to affect the maple industry in a variety of ways. This presentation describes research that has been conducted on climate change and maple as well as new ongoing work, and describe some possible effects of changing climate on the future of the industry in the northeast.

This study compared 141 ecologically relevant climate metrics to field assessments of sugar maple (Acer saccharum Marsh.) canopy condition across Vermont, USA from 1988 to 2012. After removing the influence of disturbance events during this time period to isolate the impact of climate, we identified five climate metrics that were significantly related to sugar maple crown condition. While three of these are monthly summary metrics commonly used in climate analyses (minimum April, August and October temperatures), two are novel metrics designed to capture extreme climate events (periods of unusual warmth in January and August). The proportion of climate-driven variability in canopy condition is comparable to the proportion accounted for by defoliating pests and other disturbance events.
In the Spring, maple trees begin to move sap up from their roots. At the Arnot forest, this sap is collected and then boiled down to produce maple syrup. In this video, Prof. Brian Chabot, tells us about the process and we see how maple syrup is made.
There are several important factors that affect the yield of sap from trees during the production season. One relationship that is sometimes overlooked is the one between tree size and yield. In order to develop models of tree size and yield to answer some of these questions, we measured the sap volume and sugar content from approximately fifty individuals along a wide range of sizes during the 2016 and 2017 seasons.
