Oak plantation establishment using mechanical, burning, and herbicide treatments
Abstract.Mechanical methods, prescribed burning, and herbicide treatments for establishing oak plantations are reviewed, with emphasis on herbicides. Integrated prescriptions for site preparation using these silvicultural tools are outlined for both clearcut forests and old field sites. The basic premise is that intensive cultural treatments will be required for repeated success in establishing oak plantations using either seeding or planting, when advanced natural regeneration or adequate seed trees are not present. Intensive treatments to promote rapid seedling growth appear critical to minimize the intensity and duration of animal predation on oak regeneration. Labeled herbicides and appropriate application techniques for both woody and herbaceous control are reviewed along with approaches for expanding existing labels and registering new herbicides for oak culture.
