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 The majority of timber harvests on steep terrain in the Appalachian region use ground-based skidding with bladed skid trails. Skid trails commonly occupy approximately 10% of harvest sites and are potentially erosive areas. Cable yarding systems are less commonly used in the Appalachian region, yet they have been found in other regions to cause less erosion than ground-based skidding on steep terrain. The goal of this study was to compare potential soil erosion losses from cable yarding and conventional skidding with bladed trails in the steep Appalachian Plateau region. Potential soil erosion rates were evaluated on three timber harvests in which cable yarding and conventional skidding with bladed trails were used to harvest different areas within the same timber sale unit. Potential soil erosion rates were estimated with the universal soil loss equation as adapted for forestlands. Potential soil losses were estimated in a minimum of three sample locations for each yarder operational area (deck, yarder landing, spur road, corridor, and harvest) and each ground-based skidder harvest operational area (deck, skid trail, and harvest) on three sites. Areas in each harvest operational area were also determined. Overall, cable yarder operations had less potential erosion than skidder harvests (1.70 versus 1.86 tons/ac per year, respectively). Differences between cable and skidder operations would have been greater had not the poorly designed spur roads within the cable yarder operations yielded >25 tons/ac per year of potential erosion. Cable yarder operations could have been significantly improved with additional preharvest planning and better design of spur roads.

Abstract We analyze economically optimal continuous cover forestry with dead wood as a biodiversity indicator. We study mixed-species stands consisting of Norway spruce (Picea abies [L.] Karst.), birch (Betula pendula Roth.), and other broadleaves (e.g., oak [Quercus sp.], maple [Acer sp.]). The analysis is based on an economic description of continuous cover forest management using an empirically estimated size-structured transition matrix model. We use size-specific decomposition rates for dead wood, with the lower limit on total dead wood volume varying between 0 and 40 m3 ha–1. The optimization problem is solved in its general dynamic form using gradient-based interior point methods. Increasing the dead wood volume requirement affects total stand density only slightly, but increases stand heterogeneity as other broadleaves are grown in higher numbers. In addition, increasing the dead wood requirement has only a minor effect on the total felled volume, but harvests shift from timber harvests to biodiversity fellings to maintain the required dead wood volume. In the optimal steady state with a high dead wood requirement, two harvesting cohorts emerge: one for timber harvests and the other for biodiversity fellings. Increasing the dead wood requirement decreases steady-state net timber income by up to 30 percent compared to the unconstrained solution.

This paper presents a methodology for determining the opportunity cost of a temporary removal of forested land from timber production. The value of forested land in a jurisdiction requiring sustained timber yield is the net value of the contribution of that land to the annual allowable cut. This methodology is used in a case study in west central Alberta to determine the opportunity cost of the removal of land from timber production to allow for coal extraction.
