also accounts for C emissions due to transportation and silvicultural activities. Site productivity (site
quality) was the major factor controlling stand C density followed by rotation length. Thinning reduced
C sequestration, as the slow growth rate of longleaf pine reduced the potential of C sequestration in forest
products. Prescribed burning reduced average C stock by about 16–19%, with the majority of the reduction
in the forest floor. In a comparison of longleaf pine C dynamics with slash pine (Pinus elliottii
Engelm.), both species reached a similar average C stock at age 75 years, but when averaged across the
whole rotation, slash pine sequestered more C. Nevertheless, for medium quality sites, C sequestration
