Effects of water and temperature

Abstract

Aspen's geographic and elevational ranges indicate a species that tolerates severe cold but does not tolerate sustained high temperatures, or semiarid or even dry, subhumid conditions. Much can be inferred from observation of the sites on which quaking aspen grows in the West. Aspen's distribution is related to its regeneration characteristics, its pathology, and its relations with other plants. Water and temperature, to some degree, affects each of these relationships.
