Tools and Methods in an Experimental Pruning of White Pine
The results of the study here reported show: the superiority, by virtue of lower timecosts, less tree injury, and greater labor safety, of certain tools and methods of using them for pruning dead limbs of northern white pine, with evidence that timecost need not increase with height from the ground, except as limb size increases; why selection of workers is as important as choice of tools; and that stand density has little effect on artificial pruning of this species
