General Aspects of the White Pine Situation
Abstract:The 32nd annual meeting of the Society recommended that a committee determine the financial policy which should govern the application of blister rust control. Mr. Detwiler points out that the Society has the moral obligation to review the entire white pine situation and make definite recommendations as to future production. Federal responsibility in this matter also is stressed. The white pine type originally occupied over 100 million acres in the United States. Now 20 million acres remain and three-fourths of this has been invaded by the blister rust since 1915. The rust emergency is expected to be met for the present through the work of the Civilian Conservation Corps. Adequate provision for the future calls for regional and national application of the principle of sustained yield. The white pines fulfill all of the requirements governing choice of species in forest management and rate first consideration in planning systematic softwood production. The ecological factors also favor choice of white pine as the principal tree in the management type over extensive areas since white pine was the climax species over millions of acres of original forest and was intended by Nature to permanently occupy certain sites. If America had not been invaded by the blister rust, natural regeneration and planting would have reproduced white pine on these sites. This cannot now be accomplished unless control of the disease is maintained. Control over the period of the rotation will add not to exceed a dollar per thousand feet to the average cost of white pine lumber. Ribes can be suppressed through the selection system of forest management thus further reducing the cost of control. Under these conditions it is important that the forestry profession carefully consider the facts and formulate a white pine production policy in harmony with a broad plan of economic land utilization through sustained forest yield.
