Lighter Cuts and Larger Yields in Ponderosa Pine
Abstract:Ponderosa pine is one of the most widely distributed and one of the most important forest trees of North America. Information concerning its management and expected yields is, therefore, of broad interest. It has been found that the net annual increment for blackjack is around three per cent of the original volume and that for yellow pine the net increment is usually less than one per cent. In average stands of the Southwest an average volume of 4,000 board feet per acre may be expected to yield a net annual minimum of 80 to 100 board feet over a period of twenty years. Increasing the reserve will raise the net increment only to the extent that the additional growing stock is made up of thrifty trees below 30 inches d.b.h. and so situated as to utilize growing space normally left vacant by heavier cutting.
