Abstract:

Most harvested stands of Ocala sand pine (Pinus clausa var. clausa D B. Ward) have been regenerated by direct seeding. An integrated system using a scarifier-seeder can reduce site disturbance, control spacing, and conserve seed. Modifications to this equipment to pack the soil over the seed, or to reduce the slope of the scarified spot did not improve stocking levels, but they did reduce seed movement. The alteration to reduce the slope of the scarified spot caused no mechanical problems and reduced seed displacement. Chopping to reduce competing vegetation greatly increased stocking levels, but there is little advantage to using a scarifier-seeder if sites must be chopped first. Criteria are needed for determining which sites are best suited to chopping and broadcast seeding and which to regenerate by scarifier-seeding. South. J. Appl. For. 14(2):85-88.
