Aspen Trees in Autumn

Aspen trees are a “pioneer” species of tree, meaning that it is one of the first trees to grow in an area that has been cleared by some type of disturbance, such as a fire or avalanche. The quaking aspen is unique because it reproduces by growing new trees from long horizontal roots that grow underground and send up new shoots, meaning that new trees are all clones of the original tree. This makes the trees one single organism. The aspen’s brilliant fall colors are because the leaves lose their chlorophyll, revealing their natural pigment. A hillside or slope will look dramatic in autumn because all the trees are connected and turn yellow and lose their leaves at the same time.
