Soil Disturbance Effects of Hoe-Forwarding on Tree Growth and Site Productivity: 15-Year Results at the Woss Study Site

چکیده
These effects on tree growth, which may persist for several decades (Hatchell et al. 1970, Butt 1987, Miller et al. 1996), may lead to shortand long-term reductions in tree growth and forest productivity. The level of soil disturbance will vary with soil texture, forest floor thickness, and soil water content at time of harvest (Miller and Sirois 1986, Corns 1988). In addition, machine type, size and operating practices will directly influence the level of disturbance. Concerns about soil disturbance levels from ground-based harvesting systems led to the development of the “Site Degradation Guidel ines for the Vancouver Forest Region” (BC Ministry of Forests 1991).

متن کاملImpact of Site Disturbances from Harvesting and Logging on Soil Physical Properties and Pinus kesiya Tree Growth
A study was conducted to determine the impacts of soil disturbance and compaction on soil physical properties and tree growth and the effectiveness of tillage in maintaining or enhancing site productivity for intensively managed Pinus kesiya Royle ex Gordon sites in Dedza, Malawi. The results indicate that about fifty-two percent of the area of compacted plots was affected by the vehicular traf...

Mountainous landscapes in Central Zagros are mainly used as grazing rangelands to feed animals and are heavily degraded. Overgrazing may impose a negative effect on rangeland productivity and sustainability through significant changes in soil properties. Soil nitrogen (N) mineralization is one of the key biological processes that might be affected by biotic and abiotic factors including range g...
متن کاملClimate Change, Carbon Sequestration, and Wildfire Management in Sierran Mixed Conifer Forests
2 I. Abstract We measured the impacts of prescribed fire and small clear-cut tree harvesting on carbon dynamics in a mixed-conifer forest in the central Sierra Nevada. Soil CO 2 efflux, above ground tree biomass, annual tree radial growth, and ecosystem carbon stored as litter, fine root and in the mineral soil were measured in four treatment sites: an un-manipulated control, a prescribed fire ...
متن کاملEffects of runoff harvesting through semi-circular bund on some soil characteristics
In this study, to investigate the effects of runoff harvesting on soil properties in the semiarid forest, runoff harvesting through semi-circular bund was considered as a method to conserve soil and thereby combat tree mortality. In order to evaluate this hypothesis, runoff was harvested through the semi-circular bund affecting soil quality and moisture storage. The selected forest site is loca...
