The effects of mechanical site preparation and subsequent wildfire on trembling aspen (Populus tremuloides Michx.) regeneration in central Alberta, Canada

The effects of mechanical site preparation techniques on the regeneration of trembling aspen was examined in Alberta. Although the study intended to measure growth after two growing seasons, a wildfire burned 80% of the area after the first season. The results show that in microsites where burning s...

Description
Summary:The effects of mechanical site preparation techniques on the regeneration of trembling aspen was examined in Alberta. Although the study intended to measure growth after two growing seasons, a wildfire burned 80% of the area after the first season. The results show that in microsites where burning slightly disturned the parent root system produced higher levels of suckering than where the root system was severely damaged. Regeneration at aspen sites with thick organic layers and competition from other species can be improved with mechanical site preparation.
