Seasonal Effects of Prescribed Burning on Longleaf Pine (Pinus palustris Mill.) Vigor and Mechanisms for Tolerating Repeated Crown Scorch
Prescribed burns in longleaf pine stands are utilized in 2-4 year rotations as a method of controlling competitive vegetation in such fragile ecosystems. While prescribed burns are generally considered beneficial, some studies suggest that significant leaf scorch may reduce pine production under certain conditions. Therefore, the objective of the investigators of this research is to conduct a study in the Winn Ranger District of the Kisatchie National Forest in order to determine the seasonal period when fires pose the greatest risk to pine vigor and monitor two mechanisms of longleaf pine crown scorch recovery after prescribed burns. Specific factors to be examined may include leaf area reestablishment with root starch and carbon fixation increases due to enhanced water use efficiencies and canopy level photosynthesis.
