    Description

    Effects of climate change at three aspen sites in Saskatchewan were explored using a climate-driven model that includes insect defoliation. A simulated warming of 4-5 °C caused complete mortality due to drought at all three sites. A simulated warming of 2-2.5 °C caused complete mortality of aspen at the parkland site, while aspen growth at two boreal sites showed little change from the present climate until after insect defoliation, when dieback was more severe under the warmer climate. The results suggest that future impacts of climate change on boreal aspen forests may not become evident until after major insect outbreaks have occurred.
