the Green Mountains, is covered by the conifers and northern hardwoods of the New England-Acadian forests.
Climate change appears to be affecting the maple sugar industry. Sugar maples have been subject to stress by acid rain, asian longhorn beetles, pear thrips, and, in 2011, an excessive deer herd that is forced to eat bark in the winter. These maples need a certain amount of cold to produce sap for maple syrup. The time to tap these trees has shrunk to one week in some years. The tree may be replaced by the more aggressive Norway maples, in effect forcing the sugar maples to "migrate" north to Canada.
