Abstract

The effects of soil-applied and stem-injected herbicidal techniques of forest conversion on soil moisture, pine establishment and understory vegetation were determined in an Appalachian hardwood forest. Grid applications of fenuron (1,1-dimethyl-3-phenylurea) at 11.2 kg/ha were as effective in killing tops and controlling sprouting of hardwood species as the injection application with 2,4,5-T [(2,4,5-trichlorophenoxy)acetic acid] and fuel oil. Survival of white pine (Pinus strobus L.) was higher with 5.6 kg/ha than with 11.2 kg/ha of fenuron pellets. The growth in height of pines growing under reduced competition was considerably greater than for pines growing in competition with hardwoods. During the second growing season after treatment significantly more soil moisture was present in the plots treated with fenuron and 2,4,5-T than in the untreated ones. Herbaceous vegetation and understory woody plants increased after the herbicide treatments. The third season following herbicide treatment twenty-seven species were recorded on the treated areas that were not present on the untreated control areas.
