Impacts of preharvest and postharvest residual stem control methods on stand development twelve years after harvest of a mature upland hardwood stand.

ABSTRACT

Preharvest treatment with injections of all unwanted stems (0.5-4.5 cm d.b.h.) of desirable and undesirable species, preharvest injection of only undesirable species followed by chainsaw felling after clear felling, and postharvest chainsaw felling were tested for control of residuals after clear felling a mature upland hardwood forest near Asheville, North Carolina. After 12 yr, the free-to-grow stocking of desirable species was substantial and similar regardless of method of controlling residual stems. Yellow poplar [Liriodendron tulipifera] and black cherry [Prunus serotina] were the most prevalent species. Oak [Quercus spp.] stocking, which comprised a small component of the desirable species, was not affected by method of control. Postharvest felling did lead to more undesirable species that were free-to-grow than did preharvest treatments, but differences were small after 12 yr.
