Title: Conversion of Upland Loblolly Pine-Hardwood Stands to Longleaf Pine

Project Proposal Abstract: Forest managers wishing to restore upland loblolly pine-hardwood forests to longleaf pine often have stands with poorly developed herbaceous plant communities and dense understories of shrnbs and vines. Subsequently, sites newly planted to longleaf pine, following harvesting and site preparation, will not burn evenly or with enough intensity because they do not have the necessary fine thel bed to carry a fire. Instead, aggressive hardwood sprouts and seedlings of other pine species encroach. We believe this vegetation will again form a midstory with draped and laddered fliels creating a high fire danger even though a prescribed burning program was initiated. To study this possibility, we will evaluate changes in thel load conditions on recently harvested upland loblolly pine-hardwood sites over time. Specifically, we will establish three 6 to 8 ha (15 to 21 acre) blocks. Two conversion treatments will be randomly assigned to 2 to 3 ha (5 to 7 acre) stands within each of the three blocks: (1) clearcut and (2) clearcut with reserved longleaf pine, which will be compared to (3) unharvested forest. The two clearcut treatments or stands will have been planted with longleaf pine seedlings. In addition, three treatments will be assigned within each of these stands: (a) untreated condition, (b) control burning, and (c) control burning and supplemental woody plant control by mechanical means. This will create a split plot randomized complete block design with three blocks as replicates, three main plot treatments per block, and three subplot treatments per main plot. We will then critically evaluate changes in fuel load condition and vegetative composition and structure in response to different treatment combinations. A project of this nature normally lasts for 15 years and is directly applicable to the management of longleaf pine across the Southeast. Results can also be used in model development.
