DescriptionThe southern pine beetle has shown a dramatic decline in outbreak activity over much of the southeastern States since the turn of the 21st century compared to previous decades. Concurrently, from the 1950s through the present day, a twenty-fold increase in pine plantation area has occurred across the region while trends in genetic tree improvement and pine silvicultural advances have seen a marked increase in application towards the end of the 20th century. We examine southern pine beetle outbreaks in the Piedmont and Coastal Plain physiographic provinces of the southeastern U.S. relative to this increase in pine plantation area and intensive management. While climate and natural enemy hypotheses are discussed, the substantial changes to the management and condition of the southern pine resource in the form of plantations that are genetically improved, younger, faster growing, less overstocked or more fragmented may provide a more robust explanation for regional declines in SPB
