The stand hazard index is a function of Crown Competition Factor and tree species diversity. The index showed a strong correlation with the number of trees killed by the fir engraver during a 3-year period. This model (SHR) should assist forest managers in assigning management priorities for the application of cultural treatments to reduce or prevent engraver-caused mortality. Forest Sci. 23:103-110.",
