DescriptionA thinning levels study was initiated in Southeastern Oklahoma in the spring of 1984. The study was installed in a 9 year-old loblolly pine (Pinus taeda L.) plantation that contained 110 ft2/ac of basal area. Thinning treatments consisted of (1) three control plots (BA-100) that were never thinned and contained an average of 860 trees/acre (tpa) at the beginning of the study (2) three plots that were thinned to approximately 25 percent of the original basal area (BA-25), basal area averaged 34 ft2/ac after thinning and (3) three plots that were thinned to 50 percent (BA-50) of the original basal area, 54 ft2/ac. In 1988 the BA-50 and BA-25 plots were rethinned to a basal area of 50 ft2/ac. No other thinning has been done through age-24.
