Its exact boundaries are frequently difficult to delimit where the type merges into the hardwood type but roughly it covers the lower parts of Maine, New Hampshire, Vermont and Massachusetts and the more elevated portions of Connecticut. In New York and the Lake States it is a lowland type but only occurs in the northern parts. The growing season is distinctly longer than with the two types previously considered. Ordinarily frosts do not occur between May 1 and September 15 so that there is a vegetative period of about five months. Moreover, the temperatures are higher. For the year the mean is 50 F. while during the summer the maximum is 100 F. with an average of 65 F.
