Abstract In this article a departure has been made from the usual idea prevailing in the Southwest and quite generally throughout the Forest Service that large trees which are more than an average risk should be cut. This idea would probably be sound if it were not for the fact that under present conditions we have extensive areas of virgin timber which can not be cut within 50 years. Under these circumstances there will probably be less loss by leaving thrifty large trees on cut-over areas than if these trees are cut and a corresponding volume of decadent trees left uncut in virgin stands.
Hermann Krauch (Mon,) studied this question.
