Abstract
Dense ground covers of fern and grass interfere with the regeneration of Allegheny hardwoods. An herbicide containing N-phosphonomethyl glycine controls the fern and grass, but also kills advance reproduction of desirable tree species. Preliminary results of an experiment comparing regeneration 3 years after herbicide-clearcuts and herbicide-shelterwood seed cuts showed that the amount of desirable hardwood reproduction was substantially greater in the shelterwood treatment than in the clearcuts. Clearcuts were dominated by black cherry, whereas shelterwood cuts contained nearly equal mixture of black cherry and red maple. The herbicide-shelterwood sequence appears to be more reliable than the herbicide-clearcut treatment in obtaining adequate reproduction of desirable species.
