Characteristics of Residues in a Balloon Logged Area of Old-Growth Douglas-Fir

摘要

The volume and character of residues in a 44-acre old-growth Douglas-fir stand in the Oregon Cascades were determined before and after the area was clearcut and balloon logged. The gross volume of residues on the ground increased from 5,585 cubic feet per acre before logging to 8,539 cubic feet after logging--a 53 percent increase.
