Spring frost and decay fungi are implicated in suppressing aspen re-growth following partial cleaning in juvenile stands
International audience Aspen (Populus tremuloides Michx.) regenerates at high densities following manual cleaning.* Ten-year-old stands located near Lac La Biche and Peace River, Alberta were manually cleaned to three densities (0, 500 or 1500 stems ha−1) at three times (bud set, dormancy or bud flu...

International audience Aspen (Populus tremuloides Michx.) regenerates at high densities following manual cleaning.* Ten-year-old stands located near Lac La Biche and Peace River, Alberta were manually cleaned to three densities (0, 500 or 1500 stems ha−1) at three times (bud set, dormancy or bud flush) to test the hypothesis that maintaining residual aspen reduces regeneration.* At Lac La Biche up to 98% of the aspen regeneration died in the partially-cleaned plots compared to 67% at Peace River five years post-treatment.
