Man-hours required for tree removal, trimming and stump removal are presented. Interactions between man-hours required, diameter class, season, overhead electric wires and species were examined. Diameter class influenced all work types. Season influenced tree removal and stump removal. Overhead electric lines influenced the trimming operation. Tree species did not influence any of the work types studied. ER -
