Contrasts in certain physical factors in Fagns-Acer and Quercus-Carya communities in Brown and Bartholomew counties, Indiana

摘要

Oak-hickory forests occur in Indiana under three sets of ecological conditions. First, in the northern fifth of the state, roughly north and west of the Tippecanoe river (except for the northeast corner, i. e., Steuben and part of Lagrange counties), they are the most mesophytic type of forest that will be permanently maintained by the general climate of the area and, therefore, become the climax association.
