Effects of partial cutting on diseases, mortality, and regeneration of Rocky Mountain aspen stands.

Abstract

Logging wounds on residual aspen, in partially cut stands, predisposed wounded trees to attack by insects and diseases. Five to 7 yr after cutting, aspen mortality amounted to 20%; 41% of live trees were infected with canker diseases; and 30% were infested with wood borers. Adequate sprouting occurred even though only 60-80% of the basal area was removed.-Authors
