    A ponderosa pine stand growing at a net rate of 618 board feet per acre per year may be rather amazing to foresters accustomed to the proverbial slow growth of this species in the virgin forest. Yet that is the average increment for the last 6 years of a 102-year-old even-aged stand on Lookout Mountain in the Pringle Falls Experimental Forest in central Oregon. During the same period an adjacent stand from which 25 percent of the merchantable volume was thinned in 1938 grew at the rate of 566 board feet per acre per year. At this rate, by 1949 the thinned stand will have regained the volume removed in cutting.
