Southern pine beetle impacts on forest ecosystems

Research ecologist Katherine Elliott and her team found that cutting and burning sites reduces heavy fuel loads, improves soil nutrient status, and opens the canopy for restoration of shortleaf pine communities. However, poor pine regeneration was observed due to drought, seed production issues, and hardwood competition.
