Preparing Cutover Woodland for Longleaf Establishment
Larry J. Such

“There is a strong, direct, and positive correlation between percent survival and initiation of height growth with intensity of site preparation”
(NCFS Forestry Note No. 61, “Establishment and Growth of Longleaf Pine on Droughty Sites in North Carolina, May 1988”
“Longleaf pine is a very intolerant species and is difficult to regenerate without effectively controlling competing vegetation”
(“Regenerating Longleaf Pine with Artificial Methods”, USDA, Forest Service, Southern Forest Experiment Station, 1989”
“Much of the failure in (longleaf) plantations is due to submarginal nursery stock or inadequately prepared planting sites.”
(“Longleaf Pine Management”, USDA, Forest Service, Forestry Report R8-FR 3, December 1983)
“Longleaf . . . will grow best in the complete absence of all competition, . . . ”
(“Silvics of North America”, Vol. 1, USDA, Forest Service, Ag. Handbook 654)
“. . . it is imperative that adequate site prep be completed prior to tree planting . . .”
(Don H. “Zippo” Robbins, 1996 memo to Technical Development Unit)
Site Prep Considerations?
Site Prep Methods
Mechanical / Heavy Equipment
For best results
Keep the blade sharp!!
Site Prepared - KG Sheared, Piled, Bedded
Drum Chopped Area
Site Prep - Chopped & Burned
Chopping minimizes soil disturbance
Savannah Bedding Plow
V-Shear & Bed
Burning after chopping or herbicide treatments makes tree planting easier and more likely to succeed!!
Burning removes the litter layer which facilitates planting seedlings at the proper depth
If you plan to plant longleaf, do it right the first time -- don’t scrimp on the site prep. Inadequate site prep will cost more in the long run!!!
“First year survival is often more difficult to attain with longleaf pine than with other (pine) species. The seedlings usually remain “in the grass” (stage) for 3 to 5 years, and, . . . Places longleaf at a disadvantage in comparison with other southern pines. It also handicaps longleaf in competition with hardwood sprouts and brush and even grass and weeds, . . . Where height growth is unduly delayed, mortality is likely to continue annually for many years.” * [Source: “Planting the Southern Pines”, Philip Wakeley, USDA -FS, Ag. Monograph No. 18, 1954]
