Description:	Advance regeneration, sprouts and seeds are sources of reproduction in the regeneration of mixed hardwood stands following harvest. The control of undesirable, non-commercial, competing vegetation is a common technique in site preparation to promote the establishment and growth of desirable species. This study was designed to evaluate the effectiveness of pre- and post-harvest site preparation treatments in the regeneration of an upland hardwood stand near Oak Ridge, TN. Four site preparation treatments (pre- and post-harvest slashing, with and without herbicide stump treatment) and a control (no slashing or herbicide treatment) were implemented. Each set of five treatments was replicated six times. The regeneration harvest was conducted during the winter of 1996-1997. After ten growing seasons, there was little statistical difference in species composition between treatments. Even though many undesirable existing stems were controlled by the pre- and post-harvest site preparation treatments, the proliferation of light-seeded species, primarily yellow-poplar (Liriodendron tulipifera), red maple (Acer rubrum), black cherry (Prunus serotina), and Virginia pine (Pinus virginiana) overcompensated for the various site preparation treatments.
