Developing A Field Indicator For Suckering Ability Of Quaking Aspen, Abbey M. Hudler Oksness

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Quaking aspen is an ecologically valuable deciduous tree species in the high elevation environment typical across many parts of western North America. It is a clonal tree species which primarily depends on vegetative regeneration by root suckering after an aboveground disturbance, e.g., wildfire, removes the stems. A flush of suckers will be stimulated after a disturbance and the resulting regeneration relies on available resources from the undamaged root system for resprouting. Due to wildfire suppression efforts of the last century, many aspen stands are considered mature, overmature, or decadent and lack regeneration to replace the overstory mortality. In the absence …
