Prospects for long-term ash survival in the core emerald ash borer mortality zoneThis article is part of a larger document. View the larger document here.
Attacking all North American ash species (Fraxinus spp.), emerald ash borer (EAB) (Agrilus planipennis Fairmaire) has caused significant mortality within its introduced range. For other forest pests, host bark plays an important role in infestation density and oviposition behavior. The objectives of this study were to (1) locate live ash trees in the core EAB-induced mortality zone in southeastern Michigan, (2) examine differences in live and neighboring dead trees in terms of d.b.h. and bark roughness, and (3) develop a deployable and simple ash mortality probability model.
