Special Issue Information

Dear Colleagues,

Traditionally, wood production has been the main objective of forest harvesting and transportation operations, supplying raw materials (i.e., logs and wood chips) to the forest products manufacturing sector. While this is still an important objective of today’s forest operations, the equipment and systems are now often employed to address other forest restoration issues such as forest, watershed, and wildlife habitat improvement, and fuel treatments to reduce wildfire risks. The use of forest harvesting systems and equipment as a tool for a wide range of forest restoration objectives is now increasingly common, as we often deal with changing climactic conditions, threats from wildfire, as well as the continued maintenance of actively managed stands.

This Special Issue will illustrate and exchange ideas about how forest management tools and practices that are commonly used in today’s forest operations can effectively accomplish a wide range of forest restoration objectives. We would welcome any topics and examples of original research articles showcasing the use of forest operations as a means to accomplish forest restoration objectives, such as (but not limited to):

  • forest ecosystem restoration treatments
  • controlling the spread of insects and pests
  • enhancement of wildlife/fish habitats and biodiversity
  • increased watery yield and supply,
  • removal and utilization of non-native species
  • fire hazard reduction,
  • utilization of woody materials resulting from forest restoration treatments, and
  • other innovative forest operations that contribute to the success of forest restoration.

Interest in the production of renewable energy using forest biomass is increasing in South Korea, and improved knowledge on operations logistics to lower biomass harvesting costs is needed. This study aimed to build a low-cost forest-biomass harvesting system by analyzing the costs of two integrated (cut-to-length and whole-tree) harvesting systems for logs and logging residues. Two integrated harvesting systems were carried out in the clear-cut mixed forest on a steep slope. Compared to the cut-to-length system that separately extracts logs and logging residues in a forest, the cable whole-tree harvesting system can save $8.8/green weight ton (Gwt) because it requires no additional yarding operation cost of logging residues. Moreover, a breakeven analysis shows that the required machine utilization rates that favor whole-tree harvesting systems over cut-to-length harvesting were more than 70% for cable harvesting systems. The introduction of the whole-tree harvesting system is, therefore, required to produce forest biomass at a low cost. In the future, studies on forest-biomass processing and transportation systems will be needed to provide a biomass feedstock supply cost from stump to biomass power plant. Full article

In South Korea, logs for low-value products, such as pulpwood and fuelwood, are primarily extracted from harvest sites and transported to roadside or landing areas using small shovels. Previous studies on log extraction, however, have focused on cable yarding operations with the goal of improving productivity on steep slopes and inaccessible sites, leaving small-shovel operations relatively unexamined. Therefore, the main objectives were to determine small-shovel extraction productivity and costs and to evaluate the impact of related variables on productivity. In addition, we developed a model to estimate productivity under various site conditions. The study took place in 30 case study areas; each area has trees with stems at a diameter at breast height ranging from 18 to 32 cm and a steep slope (greater than 15%). The areas ranged from 241 to 1129 trees per hectare, with conifer, deciduous, and mixed stands. Small-shovel drives ranged from 36 to 72 m per extraction cycle from stump to landing. The results indicated that the mean extraction productivity of small-shovel operations ranged between 2.44 to 9.85 m3 per scheduled machine hour (including all delays). At the forest level, the estimated average stump-to-forest road log production costs were US $4.37 to 17.66/m3. Small-shovel productivity was significantly correlated with stem size (diameter at breast height and tree volume) and total travelled distance (TTD). However, a Pearson’s correlation analysis indicated that stand density and slope did not have a significant effect on productivity. Our findings provide insights into how stem size and TTD influence small shovel performance and the predictive ability of productivity. Further, this information may be a valuable asset to forest planners and managers. Full article
