Description: A common study design has been installed at 14 locatoins Southwide to track the growth of loblolly pine established with four different competition control treatments: (a) no control, (b) woody control, (c) herbaceous control, and (d) total control after site preparation. This regionwide investigation is the Competition Omission Monitoring Project (COMP). During the first 5 years, the general pine response by treatment has been greater growth in height, diamter, and volume index as follows: total control > herbaceous control > woody control > no control. Generally, diameter growth was more responsive than height to vegetation control treatments.
