Sustaining Aspen in Western Landscapes: Symposium Proceedings
USDA Forest Service Rocky Mountain Research Station
Vegetative regeneration of aspen can be initiated through manipulations that provide hormonal stimulation, proper growth environment, and sucker protec- tion—the three elements of the aspen regeneration triangle. The correct course of action depends upon a careful evaluation of the size, vigor, age, and successional status of the existing clone. Soils and site productivity, competition from other plants, and the potential impact of browsing animals upon new regeneration should also be consid- ered. Treatments may include doing nothing, commercial harvest, prescribed fire, mechanical root stimulation, removal of competing vegetation, protection of regenera- tion from herbivory, and in limited circumstances, regenerating aspen from seed.
