Title: Reproduction of western yellow pine in the Southwest
Author: Pearson, G.A.
Subject: Ponderosa pine (Pinus ponderosa)
Abstract: Western yellow pine (Pinus ponderosa) has by far the greatest commercial importance of any tree in the Southwest. In 1908 it constituted 96.5 per cent of the lumber cut of Arizona and 87.7 per cent of the cut in New Mexico. The extensive pure stands of it in this region are now being heavily logged, and this exploitation will undoubtedly increase. Therefore the perpetuation of the trees becomes a problem of vital importance. Reproduction has not been satisfactory, either in the virgin forest or after lumbering operations, and large areas once overed with good stands of yellow pine are now practically bare. The artificial reforestation of denuded areas is impracticable at present, yet a study made in 1908 indicates that proper methods of management will insure a satisfactory second growth.
