Soil erosion is of the most important environmental challenges and factors of forest damage, which is, occur because of the land use change, road construction and lack of vegetation cover. Forest soil is naturally penetrable but forest roads are not. This issue causes the flows runoff on road surface and washes soil particles. Thus, forest roads must be planned and constructed accurately. So, t...

In the high forests which managing with close-to-nature silvicultural method, the future of forests depends on the stable establishment of saplings planted in the gaps; hence, the current study was done by selection sampling method with the aim of qualitative and quantitative investigation of natural regeneration based on the gap area in two different beech (Fagus orientalis Lipsky) forests: pu...

We present a stochastic dynamic programming approach with Markov chains for optimal control of the forest sector. The forest is managed via continuous cover forestry and the complete system is sustainable. Forest industry production, logistic solutions and harvest levels are optimized based on the sequentially revealed states of the markets. Adaptive full system optimization is necessary for co...

physiological factors have effects on most forest parameters such as forest classification so that understanding knowledge about this subject is important to manage forests. the forests of sorkhake-sanjabi village with area of 1645 ha located in eslam abad city, kermanshah province, iran were selected. 23 sample plots with rectangular shape (40m*50m) were selected and the species, origin of spe...

Estimating the amount of variation due to spatial dependence at different scales provides a basis for designing effective experiments. Accurate knowledge of spatial structures is needed to inform silvicultural guidelines and management decisions for long term sustainability of forests. Furthermore, geostatistics is a useful tool to describe and draw map the spatial variability and estimation o...
