Aiding blister rust control by silvicultural measures in the western white pine type

Abstract

The forest industry of the Inland Empire depends on the production of western white pine (Pinus monticola Dougl.) as a major species. Continued production of this tree is impossible unless white pine blister rust (Cronartium ribicola Fischer) is controlled. Existing merchantable timber can and probably will be harvested before serious losses occur, but the young growth that will determine the future of the industry is the great value at stake. The stakes are large. According to Matthews and Hutchison, "A lumber industry with white pine has greater prospects for security, stability, and prosperity than in industry dependent solely upon the other less valuable kinds of timber. To the extent that the lumber industry is more secure and prosperous, the communities of the white pine belt will be more secure and prosperous.
