Through the increased combustion of fossil fuels, humans have dramatically increased pollutant additions of sulfur and nitrogen into the atmosphere wher eit combines with water to form sulfuric and nitric acids, creating acid rain. This article investigates the impact of this issue on sugarbush health.
For the past several years we have been conducting researcg and extension on tapping birch trees for their sap and syrup production. This article presents some of the lessons learned to date on some of the most frequently asked questions about tapping birch trees.
Severe and extreme weather has significant impacts on sugar maples. This article discusses how to look for signs of stress, and how to manage sugarbushes for resilience.
Climate change trends, the impact on maple syrup production, and mitigation strategies.
Slides from a presentation on how sugar maples adapt to drought and other effects of climate change.
Sugar maple (Acer saccharum) is a highly valued tree in United States (US) and Canada, and its sap when collected from taps and concentrated, makes a delicious syrup. Understanding how this resource may be impacted by climate change and other threats is essential to continue management for maple syrup into the future. Here, we evaluate the current distribution of maple syrup production across twenty-three states within the US and estimate the current potential sugar maple resource based on tree inventory data. We model and project the potential habitat responses of sugar maple using a species distribution model with climate change under two future General Circulation Models (GCM) and emission scenarios and three time periods (2040, 2070, 2100).
This research was conducted to determine whether tapping below the lateral line in vacuum tubing operations results in the same quantity of sap from a taphole as normal (above the lateral line) tapping, and thus whether tapping below the lateral is a reasonable management alternative which might be employed to increase the size of the tapping band in maple sap production. It will also inform us as to any tradeoffs (reductions) in yield that might result from this approach.

Short and long-range weather forecasts can both be useful to determine the proper time to tap. But both also have limitations.
The University of Vermont Maple Benchmark project is advancing the study of maple economics and supporting management decision making at the individual business level. The following article summarizes the cost of production findings from 2014 and synthesizes key trends in business management.
