Equipment Trials for Uprooting Root-Rot-Infected Stumps
Abstract:Root residues were measured following stump-root extraction 1 year after harvesting a 55-year-old Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) stand with 20% infestation of Phellinus weirii (Murr. Gilbertson) root rot. A D8 Cat, a 180-hp (large) backhoe, and a 115-hp (small) backhoe were each used to uproot stumps on 1.2-1.3 ha blocks. All treatments resulted in less than 10% of root volume remaining in the soil compared with pretreatment volumes calculated from dbh-root volume relationships on a similar site. Average numbers and lengths of root residues/m³ soil were significantly greater for the small backhoe than for the other treatments, and volume was greatest for the D8 Cat treatment. The large backhoe treatment resulted in smaller residual volumes than the other treatments. West. J. Appl. For. 3(3):80-82, July 1988.

- Each regional journal of applied forestry focuses on research, practice, and techniques targeted to foresters and allied professionals in specific regions of the United States and Canada. The Western Journal of Applied Forestry covers the western United States, including Alaska, and western Canada; WJAF will also consider manuscripts reporting research in northern Mexico that has potential application in the southwestern United States.
