Spectroradiometric Measurements of Tree Species in the Caspian Forests of Iran
Forest type maps play a significant role in sustainable forest management. For many years aerial photos and satellite data were a primary data source supporting forest type mapping. Recent developments in remote sensing provide opportunities to further enhance forest type maps by introducing variations of spectral, biochemical and biophysical properties at various scales. A structural sampling ...
متن کاملStress Response of Dominant Forest Tree Species South of the Caspian Sea in Relation to Soil from Coast to Upland
Distribution and growth of plant species is affected by many factors including abiotic (topography, altitude and soil) and biotic (root symbiosis) factors. In light of global warming, recent findings advocate microhabitats and micro-conditions of the root zone and canopy ambiance as determining factors in sustaining of plant populations. Although, occurrence of ectomycorrhizal (ECM) and non...
متن کاملShape of Skidder Productivity Function for Ground Based Skidding System in Caspian Forests
Cut-to-length (CTL) timber harvesting technology currently accounts for approximately 90% of Caspian forests. The technology involves felling, branching, cross-cutting, and then the skidder carries the logs to a landing, where the timber is temporarily stored, sorted and assembled for transportation to the mill. Cut-to-length systems typically require less labor, less access road construction, ...

متن کاملOptimal Forest Road Density Based on Skidding and Road Construction Costs in Iranian Caspian Forests
Information on the productivity, costs and applications of the logging system is a key component in the evaluation of management plans for the rehabilitation and utilization of Caspian forests. Skidding and road construction costs are expensive forest operations. Determining the optimum forest road network density is one of the most important factors in sustainable forest management. Logging me...
