Abstract

Quaking aspen (Populus tremuloides Michx) exerts significant influence on the function and diversity of boreal and subalpine forests of western North America. Aspen’s expansive range highlights its success in adapting to a variety of environmental conditions. Recent patterns of dieback and habitat loss suggest that shifts in environmental conditions appear to be placing constraints on aspen vigor in some, but not all portions of its western range. The objectives of this chapter are to outline recent trends in aspen’s status in western North America and to establish a physiological framework for understanding current and future trends in aspen ecology in the context of succession dynamics, shifts in climate conditions and biotic factors, and aspen’s clonal nature. The literature suggests that aspen decline is occurring in some areas but that trends are highly variable depending on: site characteristics, fire and succession, extreme climatic events, biotic agents, and human influence.
