Innovations in Seed Orchard Management in the Southern Appalachians

Three recent innovations in seed orchard management are described. Prescribed fire was found to be an effective replacement for chemical control of the white pine cone beetle in a clonal orchard. A seed collection method which retrieves seed after it drops on netting spread over the orchard floor can be used in pine seed orchards located on sloping sites. British tree shelters enhanced both survival and height growth of planted oak seedlings. Additional Keywords : prescribed fire, insect control, seed collection, net retrieval, Pinus strobus , P . echinata , P. virginiana , tree shelters, Quercus spp., hardwood regeneration.
