Regeneration and Growth following Silvicultural Treatments in a Productive Central Hardwood Forest

The lack of desirable oak (Quercus spp.) regeneration on upland sites is a problem in the Central Hardwood Region. While reintroduction fire, thinning, and/or harvesting has been proposed as solution to increase regeneration, these treatments may have limited impact productive sites, and effects growth residual midstory stems not clear. This study examined response white alba) mature, oak-dominated, forest following four treatments: (1) burn, (2) thin (3) harvest (4) no treatment (control) at Trail Tears State Forest located southern Illinois. Results indicated there was significant difference density among for any size class. In addition, none resulted radial release stems. These results suggested need be modified that enough time since application, or intense enough,
