Clone Expansion and Competition Between Quaking and Bigtooth Aspen Suckers After Clearcutting

The ability of quaking and bigtooth aspens (Populus tremuloids Michx., P. grandidentata Michx.) to vegetatively regenerate dense stands of root sprouts (suckers) is well documented (Brinkman and Roe 1975). Tens of thousands of suckers per hectare are commonly produced when stands are killed by fire or removed by clearcutting
