The Aspen Project
Quaking aspen (Populus tremuloides) is the most widely distributed tree species in North America. Despite its ability to adapt to disturbance, quaking aspen is declining throughout much of its native range. The Aspen Project is a continuing research project at Oregon State University for the study of quaking aspen and its decline in the western United States.
