Predesignatedskid Trails 2.2.1.3 Reforestation

Chapter 2—Alternatives 2.2.1.2 Timber Yarding Ground-based yarding In ground-based yarding, a machine travels to the logs and pulls them to the landing. The machines used for skidding are diverse and can have wheels or tracks. Trees and logs are removed from the woods using rubber- tired skidders, tracked skidders, or forwarders. The skidders yard the trees to the landing by lifting the front end of the logs off the ground. Skidders travel on skid trails that are designated and approved by the BLM. A feller-buncher fells and bunches trees mechanically. The typical feller-buncher is track mounted. Some must move from tree-to-tree for felling, while others use a boom to fell multiple trees from a single position. The feller-buncher bundles trees for a skidder to pick up and move to a landing. A forwarder is a rubber-tired machine that typically works with a harvester. Harvesters move through the stand felling, delimbing, bucking, and bunching trees selected for harvest. Forwarders travel into the stands on the slash created by the harvester. They load the logs piled by the harvester and carry them to the road where they are ofF-loaded. The logs carried by a forwarder do not touch the ground during travel. Ground-based yarding is generally limited to slopes of 35% or less. After harvest is complete, skid trails and landings not needed for future management would be ripped, seeded, and mulched. Skyline-cable yarding Skyline-cable yarding uses steel cables to pull logs to the landing. A stationary machine, or yarder, would be located on the road and would pull logs up to the landing with one end of the log suspended. Skyline-cable yarding is typically used where the ground is too steep for ground-based yarding. Helicopter yarding Helicopter yarding can be used on nearly any terrain and is not dependent on road location or harvest treatment. Helicopters use a tag line (cable), generally 150 feet or greater, to lift the logs above the standing timber and fly them to a landing. Predesignated skid trails Skid trail routes would be specifically selected by the BLM to facilitate yarding operations. The skid trail can be an existing skid trail or newly located and is intended to be used by the yarding operator. 2.2.1.3 Reforestation Regeneration harvest units would be replanted after harvest with 300 to 500 trees per acre in the following mix of native conifers: 70% Douglas-fir, 20% sugar or ponderosa pine, and 10% incense cedar. In stands with root rot, no ponderosa pine would be planted; a mix of Douglas-fir, sugar pine, and incense cedar would be planted. In regeneration harvest stands adjacent to stands with Douglas-fir mistletoe, no Douglas- fir would be planted within 50 feet of the perimeter of the infected stand. Target stands would have 280 well-spaced trees per acre. At 1, 3, and 5 years, the BLM would conduct surveys to determine seedling survival, stocking levels, and maintenance needs (e.g., tubing, mulching, shading, scalping). Replanting would occur if needed to meet the target number of trees per acre. If necessary, competing vegetation would be removed for a 3-foot radius around planted seedlings. 15.

Implications of Selective Harvesting of Natural Forests for Forest Product Recovery and Forest Carbon Emissions: Cases from Tarai Nepal and Queensland Australia
Article Implications of Selective Harvesting of Natural Forests for Forest Product Recovery and Forest Carbon Emissions: Cases from Tarai Nepal and Queensland Australia Bishnu Hari Poudyal, Tek Narayan Maraseni * and Geoff Cockfield Centre for Sustainable Agricultural Systems, University of Southern Queensland, Queensland 4350, Australia * Correspondence: [email protected] Received: 5 July 2019; Accepted: 13 August 2019; Published: 15 August 2019 Abstract: Selective logging is one of the main natural forest harvesting approaches worldwide and contributes nearly 15% of global timber needs. However, there are increasing concerns that ongoing selective logging practices have led to decreased forest product supply, increased forest degradation, and contributed to forest based carbon emissions. Taking cases of natural forest harvesting practices from the Tarai region of Nepal and Queensland Australia, this study assesses forest product recovery and associated carbon emissions along the timber production chain. Field measurements and product flow analysis of 127 commercially harvested trees up to the exit gate of sawmills and interaction with sawmill owners and forest managers reveal that: (1) Queensland selective logging has less volume recovery (52.8%) compared to Nepal (94.5%) leaving significant utilizable volume in the forest, (2) Stump volume represents 5.5% of total timber volume in Nepal and 3.9% in Queensland with an average stump height of 43.3 cm and 40.1 cm in Nepal and Queensland respectively, (3) Average sawn timber output from the harvested logs is 36.3% in Queensland against 3 3 61% in Nepal, (4) Nepal and Queensland leave 0.186 Mg C m− and 0.718 Mg C m− on the forest floor respectively, (5) Each harvested tree damages an average of five plant species in Nepal and four in Queensland predominantly seedlings in both sites, and (6) Overall logging related total emissions in 3 3 Queensland are more than double (1.099 Mg C m− ) those in Nepal (0.488 Mg C m− ).

Investigation of Feller-Buncher Performance Using Weibull Distribution
Article Investigation of Feller-Buncher Performance Using Weibull Distribution Ebru Bilici Forestry Department, Dereli Vocational School, Giresun University, Giresun 28950, Turkey; [email protected] Abstract: With the advancement of technology in forestry, the utilization of advanced machines in forest operations has been increasing in the last decades. Due to their high operating costs, it is crucial to select the right machinery, which is mostly done by using productivity analysis. In this study, a productivity estimation model was developed in order to determine the timber volume cut per unit time for a feller-buncher. The Weibull distribution method was used to develop the productivity model. In the study, the model of the theoretical (estimated) volume distributions obtained with the Weibull probability density function was generated. It was found that the c value was 1.96 and the b value was 0.58 (i.e., b is the scale parameter, and c is the shape parameter). The model indicated that the frequency of the volume data had moved away from 0 as the shape parameter of the Weibull distribution increased. Thus, it was revealed that the shape parameter gives preliminary information about the distribution of the volume frequency. The consistency of the measured timber volume with the estimated timber volume strongly indicated that this approach can be effectively used by decision makers as a key tool to predict the productivity of a feller-buncher used in harvesting operations.

Mobility Range of a Cable Skidder for Timber Extraction on Sloped Terrain
Article Mobility Range of a Cable Skidder for Timber Extraction on Sloped Terrain Andreja Đuka *, Tomislav Poršinsky, Tibor Pentek, Zdravko Pandur ID , Dinko Vusić and Ivica Papa ID Faculty of Forestry, University of Zagreb, Svetošimunska 23, 10000 Zagreb, Croatia; [email protected] (To.P.); [email protected] (Ti.P.); [email protected] (Z.P.); [email protected] (D.V.); [email protected] (I.P.) * Correspondence: [email protected] Received: 2 August 2018; Accepted: 27 August 2018; Published: 30 August 2018 Abstract: The use of forestry vehicles in mechanised harvesting systems is still the most effective way of timber procurement, and forestry vehicles need to have high mobility to face various terrain conditions. This research gives boundaries of planning timber extraction on sloped terrain with a cable skidder, considering terrain parameters (slope, direction of skidding, cone index), vehicle technical characteristics and load size (5 different loads) relying on sustainability and eco-efficiency. Skidder mobility model was based on connecting two systems: vehicle-terrain (load distribution) and wheel-soil (skidder traction performance) with two mobility parameters: (1) maximal slope during uphill timber extraction by a cable skidder based on its traction performance (gradeability), and (2) maximal slope during downhill timber extraction by a cable skidder when thrust force is equal to zero. Results showed mobility ranges of an empty skidder for slopes between −50% and +80%, skidder with 1 tonne load between −26% and +63%, skidder with 2 tonne load between −30% and +51%, skidder with 3 tonne load between −34% and +39%, skidder with 4 tonne load between −35% and +30% and skidder with 5 tonne load between −41% and +11%.These results serve to improve our understanding of safer, more efficient timber extraction methods on sloped terrain.
