The Impact of Insects in the Northern Hardwoods Type

Abstract

The northern hardwoods type occupies about 16 percent -- 8.2 million acres -- of the commercial forest land in the Lake States. The timber has high unit values and represents about 42 percent of the total value of all the commercial forest in the region. Increasing values and markets for northern hardwoods in recent years have stressed the need for better quality in the finished product. Industry, therefore, is vitally iinterested in clear material, particularly for veneers and furniture stock and even for the relatively new use of the denser hardwoods for pulp. This interest, in turn, has focused attention on agents affecting growth and grade.
