Title: Growth and mortality of ponderosa pine poles thinned to various densities in the Blue Mountains of Oregon. Forest Service research paper

Technical Report ·
OSTI ID:128231

Growth and mortality in relation to density were investigated for 24 years. High mortality rates from mountain pine beetle occurred on some plots where values for stand-density index exceeded 140. Periodic annual increments of gross basal area and cubic volume increased curvilinearly with increasing stand density, whereas periodic annual diameter increments decreased curvilinearly with increasing stand density. Mean annual increments of board-foot volume have not culminated at age 84 years.
