Let us first put it in a North American context with climate change and atmospheric N deposition. We can research the impact that has occurred where the pest has moved through from Virginia through New England. And then we can look at stand vulnerability factors. We stand to lose trees and some stands. The outbreaks will be heterogenous: stands receiving more N in SW Nova could be more affected. Cool ravines should be less affected. Stands near the coast may be less affected because there has been less temperature change over the past 30 y.
