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.
Balsa production. The balsa tree is the fastest growing tree in the world. It can grow from a tiny seedling to an adult 90 feet high in about 5-7 years. It grows straight and tall, with a trunk of about 18 inches in diameter, and is topped by a lush crown of very large leaves.Each balsa tree produces hundreds of thousands of seeds.he other ingredients for rapid healthy growth are contributed by nature: the rich Ecuadorian soil, rainfall that averages 90 inches a year and hot tropical sunlight. Balsa wood is cultivated on plantations in Ecuador and is not harvested from the rain forest.
