Description: Height and age of understory red fir (Abies magnifica A. Murr.) were related to dwarf mistletoe (Arceuthobium campylopodum f. abietinum infection from the surrounding overstory red fir on four National Forests in California. Percentage of trees infected and intensity of infection increased significantly as height of understory tree increased. Age of understory trees appeared to be closely related to infection in only the youngest age class studied.
Key Words: Arceuthobium campylopodum f. abietinum; epidemiology; predisposing factors; cutting systems; stocking density; Abies magnifica; disease control
