Quaking Aspen
(Wide and Flat: Alternate Arrangement)
A small to medium sized tree, 30'-40' high, of rapid growth but short-lived. Most common on sandy or gravelly soils of old fields and open woods in northern Pennsylvania, but it can be found throughout the state. Important for revegetating recently cut or burned areas by sprouting from widespread roots. Its wood is used chiefly for pulp in manufacturing paper and cardboard. Many animals browse the twigs and it is a favorite food of beaver.
