Reports on the investigation of resource availability and planted longleaf pine (Pinus palustris Mill.) seedling and understory vegetation response within and among three sizes of experimentally created canopy gaps (0.11, 0.41, 1.63 ha) in a mature longleaf pine savanna. Longleaf pine seedlings and understory vegetation that showed increased growth in gaps created by tree removal; Longleaf pine seedling growth within gaps that was maximized from the uncut savanna; Increased longleaf pine seedling survival under the uncut savanna canopy observed that suggests that the overstory may facilitate establishment of longleaf pine seedlings rather than reduce survival through competition; Light quantity that was increased by tree removal; Light that was also the resource most strongly correlated with seedling and understory vegetation growth; Results that suggest that regeneration of longleaf pine may be maximized within gap sizes, due largely to increases in light availability. |
