Variation in the relative abundance of the large pine weevil among Sitka spruce plantation sites

Between 1993 and 1994 over 160 forest sites were sampled to obtain indices of pine weevil (Hylobius abietis L.) densities. Overall 48 variables were tested for their ability to explain variation in weevil numbers between compartments. The models generated from the sample data identified 14 variables as significant in influencing weevil densities. In this research note the variables are identified, and their relationship to forest management discussed.
