Current Research

My current research deals with the effects of emerald ash borer (Agrilus planipennis) on forest communities. Short-term effects, such as ash (Fraxinus) decline trajectories and responses of native and exotic species, are being monitored in a network of plots across Ohio and Michigan. An ash decline transition matrix will be created from this data and will allow managers to predict yearly ash decline and mortality in forest stands. Preliminary matrices show the potential for rapid mortality. Long-term responses of forests will be modeled using the Forest Vegetation Simulator (FVS), which I am modifying to include invasive shrub species. FVS will also be used to examine effects of management, such as invasive shrub removal and native tree planting, in forests where ash is the dominant species
