Barnett Savannah, Georgia August 25-27, 1981 Sponsored by: Southern Forest Experiment Station Southeastern Forest Experiment Station Southeastern Area State and Private Forestry Silvicultural Working Group, Society of American Foresters Georgia Cooperative Extension Service Georgia Pacific Corporation PREFACE Research findings provide benefits to society when they are communicated to and implemented by users. This principle was the rationale for the Southern Containerized Forest Tree Seedling Conference. In the 8 years since the North American Containerized Forest Tree Seedling Symposium in August 1974, southern for- esters have developed container seedling nurseries and begun large-scale planting programs. By their ex- perience and research, the state-of-the-art has been rapidly advanced. It was time to redefine the state- of-the-art for the 1980s. The conference objective was to describe and discuss the state-of-the-art of growing and planting con- tainerized tree seedlings for reforescation in the South. The program developed alternative approaches and examined the potential for expanding the use of this regeneration method. Many individuals and organizations deserve credit for the success of the conference. Each of our speakers did a fine job of covering his assigned topic. We are especially grateful for the presentations of those nurserymen who shared their trials in developing large-scale nurseries and field planting programs, so their successors need not repeat their errors. They have added more to the font of knowledge than they realize and serve as witnesses that planting containerized seedlings is a viable reforestation method. The moderators proved adept at keeping the sessions on schedule, providing insights of their own, and leading the informative discussion periods. The speakers are responsible for the content of their papers and sub- mitted them in camera-ready form. In addition to our speakers, 4 individuals merit special mention for their contributions to conference planning and arrangements: John C. Brissette, Southeastern Area State and Private Forestry, U.S. Forest Service, Jackson, Mississippi William E. Balmer (Ret.), Southeastern Area State and Private Forestry, U.S. Forest Service, Atlanta, Georgia David C. Borem, Georgia-Pacific Corporation, Savannah, Georgia H. Lamar Merck, Georgia Cooperative Extension Service, Statesboro, Georgia. Finally, we acknowledge the support of the Silvicultural Working Group of the Society of American For- esters and the exhibitors. The SAF Continuing Forestry Education and Professional Development Program awarded 16.5 hours of Category 1 credit to each conference attendee. The South's Third Forest report, published by the Southern Forest Resource Analysis Committee in 1969, stated that developing "year-long planting and seeding schedules for principal forest species" was one of the most important forest research needs to assure adequate future wood supplies. We feel that the authors have made a large contribution toward meeting that need. Through this volume, we transfer a new regenera- tion technology to you, the reader, hoping that society will be the ultimate beneficiary. Richard W. Guldin and James P.

On behalf of the U. S. Forest Now to join me in this welcome, it is my Service, welcome to the Southern Containerized privilege to introduce a gentleman from our host Forest Tree Seedling Conference. We're pleased state! Under his leadership, as State Forester, to see the diversity of background and interests the Georgia Forestry Commission started one of represented here today! While most of you are the first State Tree Improvement Programs and from private industry and public agencies here established one of the first seed orchards in in the South, we do have visitors from the West, the South. Canada and even as far away as Sweden. This conference offers a tremendous opportunity to Georgia has consistently been among the top exchange information; informally as well as in three states in the country in terms of the number the formal sessions. I hope you'll take full of seedlings produced, the number of acres planted, advantage of this time together. and the number of genetically improved seedlings produced. It is fitting, then, that we meet here The objectives of this conference are: to in Georgia! describe and discuss the state-of-the-art in producing and planting containerized tree seed- It is a real personal pleasure to introduce lings; to develop alternative approaches; and my good friend - State Forester Ray Shirley. to examine the potential use of this regeneration method for reforestationin the South! We have an exciting program and well qualified speakers to address the subject matter. However, your participation in sharing information and ideas are essential to insure the maximum benefit from this conference. These three days and the results of the meeting will be what you make it!
