Abstract - Density, milacre stocking, and height of shortleaf pine ( Pinus echinata Mill.) regeneration under 13 reproduction cutting methods were measured after 5 growing seasons across a range of reproduction cutting treatments in shortleaf pine and pine-hardwood stands in the Interior Highlands of Arkansas and Oklahoma. A subset of the full database was used to suggest trends in the data to date. After five growing seasons, six of the treatments exceeded the minimum standards for regeneration success—the clearcutting treatment, two of the three shelterwood treatments, and three of the four single-tree selection treatments. The two seed-tree methods fell short in both pine regeneration density and pine milacre stocking, whereas the two group selection treatments and the unmanaged control fell short in both pine milacre stocking and height. Key questions over the next 5-year period are whether regeneration development can be maintained as residual overstory basal area continues to increase, and whether the 10-year cutting cycle harvest in the uneven-aged stands or the partial removal cut in the even-aged stands will cause unacceptable mortality in the current regeneration cohort.
