A comparison of Nuttall oak establishment methods using improved and unimproved seedlings, seedling treatments, and site preparation intensity in the Lower Mississippi Alluvial ValleyThis article is part of a larger document. View the larger document here.
Restoration of bottomland hardwoods in the Lower Mississippi Alluvial Valley (LMAV) has increased over the past 3 decades to restore the resource, increase wildlife habitat, improve water quality, and enhance forest health and production. However, establishment successes of afforestation efforts in this region have been highly variable. This study attempted to employ proven establishment operations with new concepts to further supplement our understanding of oak establishment on bottomland sites. Two locations were established using minimum site preparation and intensive site preparation methods. Cultural factors included varying combinations of subsoiling, chemical site preparation, herbaceous release, and clipping and sheltering treatments to planted 1-0 bare-root seedling stock. An additional opportunity arose to evaluate the impacts on improved and unimproved seedling stock. Significant differences were identified between minimum and intensive site preparation treatments in regard to survival and growth variables. Additional differences were observed in seedling and planting stock treatments at each study site.
