Climate change-driven droughts and insect outbreaks are becoming more frequent widespread, increasing forest vulnerability to mortality. By addressing the impacts of climate insects on tree growth preceding death, we can better understand mortality risk under a changing climate. Here, used stature interannual (basal area increment; BAI) assess processes leading trembling aspen (Populus tremuloi...

The aspen leaf miner, Phyllocnistis populiella Cham., has caused widespread and severe damage to aspen in the boreal forests of western North America for over a decade.
