Abstract
The seed-tree method of regeneration was attempted on two sites, but the results were essentially the same as a clearcut because seeds contributed little to the regeneration. After 29 years, one stand produced 2,530 ft³/ac and the other produced 2,840 ft³/ac in trees ≥5.0 in. dbh. The sweetgum (Liquidambar styraciflua)-red oak (Quercus falcata var. pagodifolia, Q. nigra, and Q. phellos) stands reproduced to essentially the same species as the parent stands. Although the initial composition of the stands was quite different from the parent stands, they appear, through the processes of normal stand development, to be progressing toward stands that have essentially the same composition as the parent stands. Density in trees ≥1.0 in. dbh peaked between the 15th and 18th years. Cubic foot volumes in dominant-codominant trees at age 29 for the two areas were 52 and 76% sweetgum and 23 and 24% red oak. The oak component as a proportion of total overstory stocking increased with stand age. South. J. Appl. For. 12(2):73-78
