Variation in wood density by stand origin and log position for loblolly pine sawtimber in the coastal plain of ArkansasThis article is part of a larger document. View the larger document here.
A study was undertaken to investigate and report scaling factor variation for loblolly pine sawtimber in the Coastal Plain of Arkansas. Scaling factors for butt logs averaged 65.6 pounds per cubic foot for trees in stands of naturally seeded origin and 65.0 pounds per cubic foot for plantation trees. These scaling factors were not significantly different by stand origin at α = 0.05. Scaling factors for the upper logs of trees in stands of naturally seeded origin averaged 70.5 pounds per cubic foot and those for plantation-grown trees averaged 71.0 pounds per cubic foot. These scaling factors were likewise not significantly different by stand origin at α = 0.05. A seasonal trend was noted; treelength log scaling factors were numerically larger during spring and fall than those during fall and winter. These results should assist weight scaling of loblolly pine sawlogs in southern Arkansas.
