Some aspen colonies become very large with time, spreading about 1 m (3.3 ft) per year, eventually covering many hectares. They are able to survive forest fires, because the roots are below the heat of the fire, with new sprouts growing after the fire burns out. Aspens do not thrive in the shade, and it is difficult for seedlings to grow in an already mature aspen stand. Fire indirectly benefits aspen trees, since it allows the saplings to flourish in open sunlight in the burned landscape.
This species of tree may be the fastest growing tree in North America. In some locations it can put on a good 10-15 feet per year, and can often do so for several years in a row. It can continue to put on 5 feet per year even after this phase is completed, and may do so for around a quarter of a century.cacia (Wikimedia). Acacia can be an impressively fast growing tree.
