National proceedings: Forest and Conservation Nursery Associations—1996. Gen. Tech. Rep. PNW-GTR-389. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 282 p. This proceedings is a compilation of 51 papers that were presented at the regional meetings of the forest and conservation nursery associations in the United States in 1996. The Southern Forest Nursery Association meeting was held in Gatlinburg, TN, on June 25-27, 1996; the Northeastern Forest Nursery Association Conference was held in New England, CT, on August 19-22, 1996; and the Western Forest and Conservation Nursery Association meeting was held in Salem, OR, on August 20-22, 1996. The subject matter ranges from seed collection and processing, through nursery cultural practices, to harvesting storage and outplanting. Keywords: Bareroot seedlings, container seedlings, nursery practices, reforestation. Note: As part of the planning for this symposium, we decided to process and deliver these proceedings to the potential user as quickly as possible. Thus, the manuscripts did not receive conventional Forest Service editorial processing, and consequently, you may find some typographical errors. We feel quick publication of the proceedings is an essential part of the symposium concept and far outweighs these relatively minor distractions. iii iv TABLE OF CONTENTS SOUTHERN FOREST NURSERY ASSOCIATION MEETING Reforestation in Tennessee 1 Hart W.
