Aspen Competition in Norway Pine Plantations

Key Points

Aspen can outcompete norway pine, indicated by greater basal area when established.
Survival for up to five years does not guarantee plantation success, as seen in Lake States.
Systematic weed control measures like release cuttings are necessary for successful pine management.
The competition between aspen and norway pine suggests mixed associations may form without intervention.

Abstract

Abstract A record of survival, even as long as five years after planting, is no criterion of the success or failure of a pine plantation in the Lake States. On sites favorable to aspen this species may enter later, and, through its greater aggressiveness, convert the stand to a mixed association,with the aspen having a larger basal area than the pine. Systematic care by periodic weedings and release cuttings is the only remedy to maintain the pine.
