Aspen seedlings for boreal mine reclamation
Trembling aspen is a major component of the forests in Alberta. Aspen is an early successional species which occurs in both pure and mixed stands. It also provides the timber for pulp mills and oriented strand board mills with a harvest rate of nearly 12M m3 (5.08 BBF) of aspen timber annually in Alberta. Aspen normally regenerates vigorously after disturbance from root suckers in the range of 10,000–100,000 stems per hectare. However, after industrial disturbances such as mining or the creation of well sites where the soil has been removed, root suckering is not a viable regeneration option. Given the large areas to be reclaimed and reforested after these industrial disturbances, understanding the techniques to encourage regeneration from seed are important.
