. Differential effects of the 1944-56 spruce budworm outbreak in eastern Oregon. Spruce budworm Oregon; Trees Diseases and pests Oregon. 1941 1942 1944 1946 1948 1950 1952 1954 1956 1958. Figure radial and height increment comparisons and photograph of lightly damaged grand fir and adjacent Douglas-fir trees which appeared in competition. The grand fir grew faster until defoliation reduced its rate of increment below that of the Douglas-fir. In 1958s the radial increment of the grand fir again surpassed that of the Douglas-fir3 al- though height growth still lagged. 11. Please note
