Tree species employ a variety of strategies in response to climate change. When faced with a stressor (drought, fire or changes in growing conditions), species can either tolerate its effects, avoid stressor-induced damage, or re-establish after impacts. Such strategies consist of a set of mechanisms and interacting processes that operate at different biological, spatial and temporal scales. Mechanisms are characterized by traits, which are morphological, physiological, and phenological attributes that determine an organism's response to a stressor. The ability to utilize these strategies influences whether species’ exhibit tolerance or sensitivity when faced with a climate change stressor.
Researchers have created indices of tree species sensitivity for three key climate change stressors: Increased frequency of drought events, shifts in climatically suitable habitat, and increased fire intensity and frequency.
