The emerald ash borer, Agrilus planipennis (Fairmaire), is an exotic pest that was first confirmed in southeast Michigan during summer 2002. To date, over 10 million ash trees have been killed in the state. We are examining the impact of emerald ash borer on approximately 50 stands in and near the Huron River watershed in southeast Michigan. Mean percent ash dieback and mean percent dead ash varies greatly. Data on tree health is compared by location in watershed, tree species, tree size, presence/absence of emerald ash borer, and amount of live and dead basal area.
Species 1: Coleoptera Buprestidae Agrilus planipennis (emerald ash borer)
Keywords: tree health, exotic species
