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).

The range of sugar maple (Acer saccharum Marsh.) is expected to shift northward in accord with changing climate. However, a pattern of increased sugar maple abundance has been reported from sites throughout the eastern US. The goal of our study was to examine the stability of the sugar maple southern range boundary by analyzing its demography through the southern extent of its distribution. We analyzed changes in sugar maple basal area, relative frequency, relative density, relative importance values, diameter distributions, and the ratio of sapling biomass to total sugar maple biomass at three spatial positions near the southern boundary of the speciesÕ range using forest inventory data from the USDA Forest Service Forest Inventory and Analysis program over a 20 year observation period (1990Ð2010).
