Acer saccharum Range. Wikipedia. (2006)

Naturally growing sugar maples do not typically form pure stands, although people do selectively create more uniform groves called sugarbushes to facilitate maple syrup production. Generally, sugar maples are found as part of a mixed hardwood forest composed of from one to three other predominant trees. Some of the more common variants of this include sugar maple-beech-yellow birch, beech-sugar maple and sugar maple-basswood forests. These forest types, and sugar maples specifically, occur throughout much of eastern North America, from far eastern Kansas all the way to Maine and from Quebec to southern Tennessee. They are happiest, however, in New England, New York, Pennsylvania, Ohio and southern Quebec. In the southern portions of their range, they are largely restricted to growing above certain altitudes.
