Abstract A study of residual stand damage along yarding trails associated with four harvest methods—harvester/forwarder and cable skidder, tractor, and bulldozer with chainsaw felling—was conducted in a group selection harvest of a mixed hardwood stand in Maine. Tractive yardingmethods were associated with greater numbers of damaged trees per meter of trail length. In addition, the bulldozer method resulted in the largest number of damaged boles per 100 m2 of near-trail space, whereas the smallest number of damaged boles per 100 m2 was associatedwith the forwarder method. The tractor method resulted in the most root damage, and the forwarder method resulted in the largest trail width. These results have implications for equipment selection and the planning of harvests and harvest access systems.

Abstract A study of soil compaction associated with four harvesting systems—a forwarder working with a mechanized harvester and a rubber-tired cable skidder, a farm tractor, and a bulldozer, each of them coupled with a chainsaw felling—was conducted in a group selection harvest of a mixed hardwood stand in Maine. The bulldozer system was associated with the highest percentage differences in soil bulk density measured in machine tracks (16.9%), trail centerlines (15.7%), and harvested group selection units (13.1%) versus adjacent untrafficked areas, whereas the forwarder system was associated with the lowest percentage differences in soil bulk density measured in machine tracks (3.5%), trail centerlines (1.2%), and harvested group selection units (6.3%) versus adjacent untrafficked areas. Results will help to inform loggers and foresters on equipment selection, harvest planning, and the conservation of forest soils and soil productivity.

Abstract Many high-elevation stands of noble fir (Abies procera) in the northern Oregon Cascades are being actively managed. Forest managers are investigating different activities that will control stand impacts and the subsequent spread of Heterobasidion annosum, a rot pathogen on the Warm Springs Indian Reservation. The purpose of this study was to quantify the relationship between logging production and costs with associated residual stand damage during a commercial thinning operation. Investigated in the study were four ground-based harvesting systems and two different harvest unit layout methods. Harvesting costs for the four different systems and layout methods ranged from $67.75 to $92.66/mbf (thousand board feet), with residual stand damage of 20.1 to 62.6%. Equipment size, log lengths, and layout method were found to affect total residual stand damage. West. J. Appl. For. 18(2):118–126.

Abstract Fixed plot sampling was used to measure residual stand damage on 101 harvested stands in West Virginia. Damage was categorized for roots, base, bole, and crown components of all trees 4 in. dbh and greater. The level of damage was correlated to both preharvest and residual stand densities. Equations were developed to estimate stand damage, based on preharvest and residual stand basal area and trees per acre. These equations were found to reasonably estimate levels of stand damage from previous studies in partial/selection cuts, but not in thinnings. North. J. Appl. For. 16(4):191-196.

Abstract In an attempt to reduce fuel loading during commercial thinning in a mixed-conifer forest, treetops were left attached to logs that were skidded to a landing for bucking and top disposal. Designated skidtrails were used to minimize residual stand damage and soil compaction. In a comparison with conventional logging procedures, treetop skidding did not decrease skidding productivity or increase damage to residual crop trees, but neither did it significantly reduce fuels. Whole-tree skidding, which would remove lower limbs, may be necessary to reduce unacceptable fire hazard. West. J. Appl. For. 1:13-15, Jan. 1986

The practice of timber harvesting in natural forests which has been conducted up to now still leaves wood harvesting residue and residual stand damage. Most condition of wood harvesting residue is still good and can be utilized. The objective of this research was to determine the potency of wood harvesting residue and residual stand damage on timber harvesting in natural forests. The data on wood utilization, wood harvesting residue, and residual damage were collected from three sample plots. The sample plots were arranged in a systematic and purposive manner, and the data were processed with tabulation and average analysis. Research results showed that the average volume of wood being utilized was 9.212 m3 tree−1. The average volume of wood harvesting residues was 2.310 m3 tree−1, and the total average volume of wood harvesting residues which were good, defected, and broken was 2.121 m3 (80.952%), with an average volume for good wood harvesting residue condition of 1.038 m3 (34.808%). Proportions of wood harvesting residues were 2.154 m3 (94.444%) consisting of buttress as large as 0.102 m3 (5.159%), stumps as large as 0.375 m3 tree−1 (23.597%), butt as large as 0.855 m3 (35.930%), and end part as large as 0.821 m3 (29.758%). The average number of trees with a diameter of 20 cm which were damaged due to felling and skidding was 5 trees ha−1 (5.40%) and 6 trees ha−1 (6.58%), respectively.
