Post-establishment vegetation control in a Eucalyptus grandis x E. camaldulensis stand: research note

Abstract

In eucalypt plantations, the effect of shading following canopy closure reduces the growth of competing vegetation. In some eucalypt stands full canopy closure is not achieved and the important characteristic of complete shading is lost. This results in stands with the potential to support competitive levels of postestablishment vegetation. A trial was established on a two year old Eucalyptus grandis x E. camaldulensis stand to determine the competitive effect of post-establishment vegetation on tree growth. A weedfree treatment was implemented annually over a period of five years and compared to a weedy control to determine the time period for the post-establishment vegetation to reach competitive levels. There was no significant tree growth or survival response to competition from post-establishment vegetation for the duration of the trial.
