Abstract Plots were established to monitor the success of advance regeneration for red oaks and ash on eight high quality sites on minor bottoms in Mississippi. Data were collected pre- and post-harvest, and annually for 3 yr following harvest. Red oak and ash stems were initially categorized by height class, or by diameter class for those stems at least 1 in. in diameter at breast height. Survival and competitive position were monitored to provide estimates of the probability of producing at least one free-to-grow stem 3 growing seasons following stand harvest. Regardless of species, the competitive advantage of larger seedlings and stump sprouts over smaller seedlings (less than 1 ft tall) was clear. Less than 10% of the smaller seedlings were free-to-grow after 3 growing seasons, whereas 26% to 71% of the larger seedlings and stump sprouts were judged free-to-grow after the same amount of time. Results were used to revise an existing regeneration assessment system. A field tally sheet was developed to aid in the application of the revised system. South. J. Appl: For. 23(3): 133-138.
