Felling, Girdling, and Poisoning Undesirable Trees in Forest Stands

This article presents a summary of past experience in methods of eliminating undesirable trees from the forest and the results of new experiments in which poisoning with sodium arsenite was compared with girdling and felling. Very accurate time records were kept so that the cost and results of each process may be referenced to trees of different sizes and to those with soft and relatively hard woods. Under the conditions of the experiment, the authors found poisoning the cheapest and most effective method.
