Vulnerability of forest types to spruce budworm damage in Newfoundland: An empirical approach based on large sample size

A. G. Raske; M. Alvo

Abstract A clear relationship between stand characteristics and spruce budworm ( Choristoneura fumiferana (Clem.)) damage was present only for stand composition and budworm damage in Newfoundland during the 1970s. Other stand parameters were not related. A sample size of 2 031 507 was used in the investigation. The lack of a consistent correlation may have been caused by the severity of the outbreak, the randomness of mass transport of adult moths and the lack of wide diversification in species composition of forested lands.
