Commercial tree products modeling case study in Gorazbon district, Kheyroud Forest, Iran

volume, height and wood production modeling using the changes in a nine years rotation (case study: gorazbon district in kheyroud forest, north of iran)

the oriental beech constitute one third of northern forests area and stocking volume in the north ofiran. these stands obseve in pure and mixed. in order to properly management which guaranteesustained yield, it is crucial to collect basic information including stocking (volume and stem number),tree growth, diameter distribution pattern, diameter-height relationship, diameter-volume relationshi...

growth models using to simulate and investigate different forest management methods (case study: gorazbon district in kheyroud forest, north of iran)

hyrcanian forests are the most valuable forests in the north of iran and industrial harvesting occurs only in this area. it is a productive region near the southern coast of caspian sea. in these forests mixed beech stands mostly shown uneven-aged structure that is managed under selection system. in order to determine the priority of uneven aged method not only from an ecological view, but also...

quantifying the spatial structure in hyrcanian submountain forest (case study: gorazbon district of kheirud forest-noushahr-iran)

quantifying spatial structure is one of the most important components, describing natural ecosystems and their biodiversity. in this study, a set of indices and functions related to spatial structure using 102 established plots with an area of 1000 m2 were presented. to achieve spatial structure of carpinus-fagus type, a set of indices (clark & evans, uniform angle, shannon-wiener, mingling and...

an investigation on the forest structure and trees spatial pattern in fagusorientalis stands of hyrcanian forests of iran (case study: gorazbon district of kheyrud forest)

beech forests in midland areas of hyrcanian forests of iran are the most important forests having the highest degree of naturalness. these forests are the valuable source of wood production and other forest products. one of the most important characteristics of plant communities is the spatial pattern of trees. ecological process in forest ecosystems are directly influenced by the spatial patte...
