Seedlings, herbs and grasses abound in the adjacent fields were not found under the canopy of its stand. No differences between soil nitrogen and phosphorus levels inside and outside of the Chromolaena stand were detected. Light intensity under the canopy was however only 2.7% that above the canopy.
