Soil bulk density, soil strength, and regeneration of a bottomland hardwood site one year after harvest

摘要

The first year soil physical properties and regeneration measurements following harvestindicate ample regeneration on all treatments including the landing areas. Comparisons included threemachine systems (three skidders) and a helicopter-yarded control that were field tested for harvestinga bottomland hardwood site under adverse conditions. The results also demonstrate a significantlygreater number of tree stem count following the winter than the summer harvest. Results of thestatistical analysis of soil bulk density indicate that the soil had partially recovered from machinetraffic one year after harvest.
