A simple competition assessment system was evaluated as part of an intensive competition control study in a natural, even-aged stand of loblolly-short-leaf pine (Pinus taeda L.- P. echinata Mill.) seedlings in southern Arkansas. Four levels of competition control were maintained annually for 3 years as follows: (1) no competition control, (2) woody competition control, (3) herbaceous competition control, and (4) total control of nonpine vegetation. The competition assessment system is based on a correlation of total height to groundline diameter (gld) for loblolly pine seedlings that are less than 6 ft tall. The correlation indicated that if seedling gld's are not within + 10 mm of total seedling height (in feet) multiplied by 10, then the seedlings would most likely show a positive growth response to competition control
