摘要

A cacia melli f era subsp.detinens is commonly viewed as a problem plant.Total clearing of A.melli f era is thus a common practice, but re‐encroachment often occurs.The objective of this study was to determine the dynamics of A.melli f era seedlings grown in soil collected within three subhabitats : two areas under the canopies of mature A.melli f era trees, the first close to the main stem of the plant and the second approximately in the middle of the canopy and the third in open areas between the canopies of the trees.
