Description: During the period 1946-49, The Pennsylvania State University established 22 experimental plantings of trees and shrubs on strip-mine spoil banks in the Bituminous Region of Pennsylvania to determine which species were best suited for revegetating such sites. When 10-year growth on the experimental plots was evaluated, a clone of hybrid poplar was found to have outgrown all the other species tested. The performance of this one hybrid poplar suggested that other hybrid poplars might be well adapted for growing on strip-mine spoils, so we planned a screening test of as many hybrid poplar clones as possible to determine which ones were worth further consideration for use in large-scale plantings.
