Predicting the Volume and Normality of Reproduction Stands of Douglas-Fir

Abstract With the increased emphasis placed upon the acquisition and protection of land bearing only trees of reproduction size in the Douglas-fir region has come the necessity of appraising such land and preparing management plans for it. This forest land is usually classified by the stocked-quadrat method but for management purposes it is necessary to know what yields may be expected during and at the end of the rotation. The data presented here are the first attempt to bridge the gap from quadrat stocking to cubic-foot volumes at an age where yield tables may be used.
