Canadian Softwood Plywood (CSP/SPF)
Aspen
Habitat:
Trembling aspen grows best on moist, well-drained soils, especially
soils rich in calcium, such as those derived from limestone.
It is known for its ability to sprout from root suckers and form clones
of many individual stems. Aspen clones can often be distinguished in
spring or fall when groups of stems leaf out or change colour all at
once. These clones can get quite large and can be very long-lived. Some
are estimated to be over 5,000 years old.
Uses of Trembling Aspen:
After decades of being treated as a weed, the forest industry now values aspen for pulp and waferboard. It is also exported as chopsticks.
