Quaking aspen occurs on more than seven million acres of the interior western United States. It is seral on most sites, usually giving way to more shad-tolerant conifers. Regeneration is almost exclusively by root suckering -- seedlings are a rarity. Discrete clones that occupy several acres are the rule on mountainous western landscapes. Management practices reflect the values of this ecosystem. These values, in decreasing order of importance, are: livestock forage, wildlife habitat, watershed cover, esthetics and recreaction, and wood products. Wood products are gaining in importance, thus encouraging more active management of this important type.
