This is one of the most widely distributed trees in North America.
In our area they grow in high mountain valleys and on hillsides
where sufficient moisture is available.
Aspens are slender white-barked trees which tend to grow in thick
stands. They reproduce most commonly by sprouting from the roots
of an established tree, rather than from seeds. All of the trees
in a grove have probably sprouted from the roots of a single parent
tree, and are therefore clones of the original tree.
The leaves are nearly round in shape, and are about 2 inches in
They are attached to the twigs by long slender leaf stalks, which
are slightly flattened in cross section. This
causes the leaves to flutter and tremble in the slightest breeze.
In the fall they turn a bright golden yellow. (In some groves,
