Logging wounds on residual aspen, in partially cut stands, predisposed wounded trees to attack by insects and diseases. Five to 7 years after cutting, aspen mortality amounted to 20%; 41% of the 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.
