Abstract

Two articles by G. A. Pearson which appeared in the Journal of Forestry during 1944 show that in the Southwest net increment in ponderosa pine stands increases during the first ten years after cutting and then starts a downward march. In this article the author presents data from sample plots on the Boise and Salmon National Forests which show an initial period of rapid growth after cutting, followed by a decline of relatively short duration and then a decided upturn. On the basis of this evidence he concludes that the facts now available do not indicate a cutting cycle of less than 30 years in the southwestern Idaho belt of ponderosa pine.
