A simple method is described for evaluating the regenerative potential of aspen (Populus tremuloides) stands undergoing overstory deterioration. Sucker and sapling densJ.tJ.es are obtained, and based on this information, treatments involving livestock restrictions or disturbances are proposed to insure regeneration. Disturbance treatments rejuvenate aspen stands by stimulating root suckering. No treatment is necessary if the sapling density is adequate (approximately 2,100/ha). Total basal area (m2/ha) and density of overstory trees are also determined and function as indicators of the stage of deterioration. By comparing the overstory characteristics with treatment results, it may eventually be possible to better predict ability to rejuvenate aspen stands in various stages of deterioration.
