Although non-native pests and diseases are becoming increasingly important in North American forests, the impacts of these forest diseases on native fauna are not often quantified. In North America, beech bark disease is an exotic forest disease complex caused by the non-native scale insect Cryptococcus fagisuga (Homoptera: Cryptococcidae) and native and non-native fungi in the genus Nectria. It causes extensive mortality of American beech (Fagus grandifolia) and is currently spreading towards the northwestern range limit of beech. As beech bark disease progresses in a stand, increases in coarse woody debris and snag density as well as changes in the canopy and understory will likely alter habitat suitability for many species. The purpose of this study is to determine the potential impacts of beech bark disease on arthropod communities. Fifteen study sites in the Upper Peninsula of Michigan were used in this research: five in beech forests with beech bark disease, five in beech forests without beech bark disease, and five in hardwood forests without beech. Several trapping methods were used to measure community composition and species abundances at each study site. Flight intercept panel traps were baited with ethanol and longhorned beetle lures to capture wood infesting insects. Blacklight traps were used to sample nocturnal flying insects, particularly Lepidoptera. Pitfall traps were use to characterize ground dwelling arthropod communities. Differences in arthropod community structure among site types indicate that beech bark disease is altering forest arthropod communities.
