Abstract:

Felling and skidding are essential in the timber extraction process. But on the other hand, residual stand damage can’t be avoided. This study aimed to analyze the impact of conventional and improved felling and skidding techniques on residual stands in natural forests. Three observation plots were developed to identify the types, numbers, and criteria of residual stand damage due to both techniques. The criteria were categorized as a) minor damage (<25%), b) moderate damage (25–50%), and c) major damage (>50%). It showed that the conventional felling and skidding technique caused damage

Abstract:

A major component of sustainable forest management are the stands left behind after the logging operation. Large mechanized harvesting equipment involved in current forest management can inflict damage on residual trees; and can pose a risk of mortality from diseases, natural calamities, and/or degrade future economic value. The primary objective of this study was to evaluate the residual stand damage under different harvesting methods and silvicultural prescriptions i.e., crop tree release (CTR), diameter limit cut (DLC), and overstory removal (OSR). The second objective was to evaluate the i

Abstract:

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:

Minimizing the impacts to the residual stand is one of the goals of sustainable forest management. To achieve this goal it’s essential to know the dynamics of these impacts, its frequency, cause and severity. Various studies in this topic were carried out in primary tropical forest, but little is known in secondary forests, which have smaller and denser tree community. We evaluate the bole and crown damage and the incidence of leaning trees in the residual stand right after the timber harvesting in a secondary Atlantic Rainforest in southern Brazil. On average, 26% of the residual trees suffer

Abstract:

Abstract Damage to residual trees after cable logging was observed in two northern hardwood stands in Pennsylvania. In the first stand, primarily red maple and black cherry, only 8% (by basal area) sustained major damage. Felling was the major source of damage, as the amount due to yarding was negligible. The second stand, a mix of red maple, red oak, and black birch, sustained 10% major damage. The results were similar to observations made in West Virginia, and support the effort to use cable yarding for partial cuts in hardwood stands. North J. Appl. For. 8(1):15-17

Abstract Residual stand damage was assessed in 10 ac stands harvested with either a 12 in. diameter-limit harvest, a 16 in. diameter-limit harvest or an establishment cut of the shelterwood method. Each stand was logged using manual felling and cable skidding; treatments were replicated four times. The 12 in. diameter-limit harvests had the lowest residual basal areas but residual stems had the highest percentage of damage and largest stem wounds. In all three treatments, as tree size (dbh) increased and distance to skid trail increased, the probability of individual tree damage decreased.

Abstract:

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 re

Abstract:

The extent and temporal pattern of crown damage (attributed to Hymenoscyphus pseudoalbidus) in even-aged stands of Fraxinus excelsior in relation to bud flushing phenotype, stand density, and season was investigated. Data were collected in 2007 in four statistically designed thinning experiments located in 12&ndash;15-years old plantations of ash in Denmark. The study included 21 plots of four contrasting, residual stand densities: (1) 1700&ndash;5500 trees/ha (unthinned control plots), (2)&nbsp;1500 trees/ha, (3) 500 trees/ha, and (4) 100&ndash;150 trees/ha.

The objective of this study was to evaluate the damage caused to the remaining trees of a pinus stand submitted to mechanized thinning by a wheeled harvester. The data were obtained in the operational areas of timber harvesting in a forest company located in the city of Inácio Martins, in the state of Paraná, Brazil. The Pinus stand of the study was 11 years old, and was submitted to the first commercial thinning. The operation was performed by a harvester, characterized by the systematic removal of the 5th planting line to give access to the interior of the stand, followed by selective thinni

Abstract Eighteen mechanically harvested, partially cut hard- and mixed-wood stands in New England were examined to determine the extent of logging damage. Frequency of crop tree damage averaged 9.6%. Tree injury, both incidence and severity, was not related to location relative to skid trails or landings. Variations in damage level between sites was not explained by numbers of trees per acre, size of trees, or basal area prior to or after harvest, but cover type, rockiness, and season of harvest in combination accounted for a small part of the site-to-site differences.

Abstract. The trend in modern gin stand designs to increase gin stand production rate in terms of bales/h was generally achieved by increased width, narrower saw spacing, and higher saw loading. This study examined fiber length reductions, short fiber content, fiber neps, and cottonseed damage associated with five saw gin stands of differing production rates, design, and manufacture that represent a range of gin technologies developed since the 1960s to identify technologies from those earlier designs that may guide future gin stand research. Based on rated ginning rate, the gin stands were cl

Abstract:

Under external load excitation, damage such as breathing cracks and bolt loosening will cause structural time domain acceleration to have nonlinear features. To solve the problem of time domain nonlinear damage identification, a damage identification method based on the Kullback–Leibler (KL) distance of time domain model residuals is proposed in this paper. First, an autoregressive (AR) model order was selected using the autocorrelation function (ACF) and Akaike information criterion (AIC). Then, an AR model was obtained based on the structural acceleration response time series, and the AR mod

Abstract:

Abstract Following a damaging storm, managers of small forest tracts often want to know when to harvest and reforest to maximize financial return. The assessment of financial return is complicated by the need to project the product value of damaged trees and to account for the risk of another damaging storm. Methods are demonstrated for handling both these complications. The effects of stem sweep on product value is projected by incorporating a sweep distribution into a simulator for stand growth and computing stumpage value using a residual value approach in which trees are optimally allocate

Abstract Flood plains in interior Alaska support an important forest resource. Silvicultural alternatives for these sites depend on access and on the effect of timber harvesting on the residual stand and site. Some aspects (i.e., road access, logging damage to residual stand, and effect of logging on snow pack) of winter logging of white spruce on an island in the Tanana River were observed. Winter roads of snow and ice were easily developed over a variety of surface conditions and appeared to have little lasting impact. Damage to uniformly spaced residual shelterwood trees was variable.

Abstract Following a severe ice storm, one of a landowner's first considerations regarding the future of their damaged stands should be on the recovery potential of injured crop trees. The ice storms that struck Arkansas in December 2000 provided an opportunity to monitor 410 injured loblolly pines (Pinus taedaL.), representing a wide range of damage in 18–20-year-old plantations. Five-year mortality rates were <3% for trees with low to moderate injury, 16% for major damage, and 55% for critical damage. Of the most seriously affected pines, root-sprung trees had the highest periodic mortali

Cracks were the most frequent form of defect, but swelling, callus, and open cankers also occurred. Damage was observed in 192 of 1056 spots, and there was wide variation in the frequency of damage caused by different materials. There also

Abstract Partial harvesting (here defined as removal of ≤50% of preharvest volume) is the predominant silvicultural scheme applied to hardwood forest types in the eastern United States. Future stand conditions are largely reliant on trees retained after harvest, so their mortality because of harvesting activity damage should be minimized or taken into account when planning. We quantify partially harvested stand characteristics and postharvest mortality using data from 32,057 forested conditions, 366,953 trees with a diameter at breast height (dbh) ≥ 2.5 cm, of which 4,469 trees were cut and us

Abstract Silvicultural treatments designed to enhance stand structural diversity may result in increased wind damage. The ability to avoid conditions that might lead to excessive wind damage would benefit forest managers. We analyzed wind damage following implementation of a variable-density thinning at four sites on the Olympic National Forest in northwest Washington. The prescription created small canopy gaps and retained unthinned patches within a uniformly thinned matrix, thus creating substantial amounts of internal edge.
