Release cutting, live crown ratio, diameter-at-breast height, and dwarf mistletoe (Arceuthobium abietinum f. sp. magnificae). acted to affect radial and height growth of red firs (Abies magnifica A. Murr.). Infected and noninfected red firs responded well to release as expressed by increased radial growth: growth rate doubled within 10 years after release. Live crown ratio also had a marked effect on radial growth rate. Irrespective of the level of dwarf mistletoe, trees with good live crown ratios showed significantly greater rates of radial growth than did trees with poor live crown ratios. Dwarf mistletoe reduced growth but, in general, growth was reduced significantly only at the medium-to-high levels of infection. Height growth in released trees was influenced most by live crown ratio and, to a lesser extent, by dwarf mistletoe and tree diameter. In managing red fir stands by release cutting, trees with good live crown ratios, preferably the larger ones, should be left in the stand, regardless of the level of dwarf mistletoe infection.Publication Notes
