A Comparison of Sheared and Sawhead-Felled Stump Heights on Six Nonindustrial Private Timber Sales in Southeastern Virginia
Stump heights were measured on six recently harvested nonindustrial private timber sales in the Virginia coastal plain. The tracts had been clearcut by six different logging contractors. Three of the tracts had been felled with hydraulic shears, and three had been felled with continuous disk sawheads. Sawhead-felled stumps were found to be significantly higher than shear-felled stumps for both pine and hardwood on all tracts. Estimated stumpage revenue loss for the three sawhead-felled tracts due to high stumps and saw kerf was $12.04/ac. Both sheared and sawhead-felled stumps exhibited visible felling defects such as fiber-pull and barber-chair. South. J. Appl. For. 16(3):140-142.
