Abstract
Equations were developed to estimate outside-bark, merchantable stem green weight (lb) and inside-bark merchantable stem volume (ft
3) for sawtimber-sized Nuttall oak (
Quercus texana Buckley), overcup oak (
Quercus lyrata Walt.), water oak (
Quercus nigra L.), and willow oak (
Quercus phellos L.) found at two bottomland hardwood sites in southeast Arkansas. Sixty-one trees were used in this study. Trees ranged from 43 to 90 years in age (average of 62 years), 12 to 34 inches in diameter at breast height (d.b.h.) (averaging 19.5 inches), 60 to 120 feet in total height (averaging 94 feet), 27 to 77 feet in merchantable height (averaging 53 feet), and 5.4 to 26.0 inches in merchantable top diameter (averaging 11 inches). Equations were developed by species and employ a combined variable, (d.b.h.2 * total height), to facilitate ease of use based on commonly measured inventory attributes. The results of this research should assist those inventorying hardwood sawtimber-sized trees by weight or those working with scaling factors (outside-bark weight divided by inside-bark volume) in southern Arkansas.
