The Competition and Individual Size Between Two Species: Sand Pine (Pinus Clausa) W. and Longleaf Pine (Pinus Palustris) M. in Same Community

Abstract
Two experiments were conducted to evaluate competition and individual Size between two species; Sand pine (Pinus clausa) W. and longleaf pine (Pinus Palustris) M. in same community. The result show that, for the first experiment, mean circumference of P. clausa in the road/open area was 92.83 cm, and in the middle of the stand was 84.11 cm. Regard to the second experiment, mean height of longleaf pines in hardwood area was 10.30 m, and in burnt area was 10.63 m. Mean circumference of longleaf pines in hardwood area was 49.17 cm, and in burnt area was 52.31 cm. Mean heights of longleaf pines did not differ between the hardwood area and burnt area, whereas mean circumference of longleaf pines in burnt area was found to be higher than that in hardwood area. The competition in this case is inter specific, between hardwood and longleaf pines, possibly for sunlight and nutrients. In burnt area, this competition was reduced by the use of fire.
