Abstract: The major southern pine species are ecologically and economically important and consist of longleaf, loblolly, slash, and shortleaf. Longleaf pine is typically perceived as being of equal quality to slash pine, and higher in quality than loblolly pine or shortleaf pine (Kretschmann 2010). Some differences in SG between the species can be attributed to growing region. Longleaf pine typically grows near the southern coasts, a region that produces trees with “better” wood properties than those grown further north or further inland (Jordan et al. 2008). Eberhardt et al. (2017) showed that when grown in the same location, slash pine had greater SG than loblolly pine (0.523 and 0.498, respectively), but the differences were not nearly as large as those values reported in the Wood Handbook (Kretschmann 2010). Another reason for longleaf pine’s perceived quality advantage over other southern pines could also be attributed to it being obtained from natural stands rather than plantations. Because of the high growth rate in plantations, trees are harvested at younger ages, and thus the wood has a higher proportion of corewood (juvenile wood) (Jordan et al. 2008, Dahlen et al. 2018).
