Abstract

Various thinning techniques were applied to 5-year old hybrid poplar stands on bituminous strip-mine spoils. Basal and stump sprays of 2, 4, 5-T in diesel oil were effective for killing the trees. There was no evidence that chemical treatments affected adjacent trees. Where trees were cut and stumps were not chemically treated, all clones sprouted prolifically. Dominance in sprout clumps was asserted soon after thinning. Sprouting vigor was affected more by site quality than clonal parentage. Results indicate that hybrid poplar can be successfully regenerated under coppice management or can be easily removed for stand conversion.
