Nutrient status, sapwood basal area (SBA) and sapwood to heartwood basal area (S/H) were measured on second growth Pseudotsuga menztesn trees in western Montana. Armillaria ‐infected trees had significantly lower S/H ratios, growth, and foliar N and S concentrations than noninfected trees. Our results indicate a general influence of Armillaria infection on nutrient content and physiological status of P. menziesü trees. However, these measurements are not a reliable method to determine the extent of infection.
