Resource sustainability requires a thorough understanding of the influence of forest management programs on the conservation of genetic diversity in tree populations. To observe how differences in forest management affect the genetic structure of Fagus orientalis Lipsky (oriental beech), we evaluated thirteen beech sites across Hyrcanian forests, based on six microsatellite loci. Significant di...

gross rainfall (gr) partitioning into throughfall (tf), stemflow (sf) and interception loss (i) was studied in a pure oriental beech (fagus orientalis lipsky) forest located in the central caspian region of northern iran. measurements were performed on a rainfall event basis in a 5625 m2 plot of the kheyrud forest research station of tehran university during 2008 and 2009 growing seasons. gr wa...

we studied 11 gaps covered with beech saplings (< 1.30 m tall) in a reserve compartment (compartment 139, district one, langa forest, watershed 36: kazemrood) of the caspian beech forest in n iran. two transects, each 2 m wide, were laid along the longest (n-s) and shortest (e-w) axis of each gap. five micro sample plots, each 4 m2, were established: one at the center, and one at each corner. q...

We studied 11 gaps covered with beech saplings (< 1.30 m tall) in a reserve compartment (compartment 139, district one, Langa forest, watershed 36: Kazemrood) of the Caspian beech forest in N Iran. Two transects, each 2 m wide, were laid along the longest (N-S) and shortest (E-W) axis of each gap. Five micro sample plots, each 4 m2, were established: one at the center, and one at each corner.

canopy gaps are one of the most important structural features of forest ecosystems, and studying of them can have useful results and implications for forest management. the aim of this study is investigation of characteristics and regeneration within canopy gaps in an intact beech stand in the shastkalateh experimental forest of hyrcanian region, north of iran. all canopy gaps and related fores...

Modification of stands’ structure and managing them using silvicultural methods close to nature and single selection system require information on status of structure, determining the target diameter, basal area and suitable volume to result in long-term equilibrium and sustainability. So, this study was conducted using the selection sample statistical method by selecting  five 1-ha sample plot...

Species diversity is one of the most important indices used for evaluating the sustainability of forest communities. This study aims to characterize the forest communities and to identify and compare the plant species diversity in the study area. For this purpose, 152 relevés were sampled by a randomized-systematic method, using the Braun-Blanquet scale. Classification of the vegetation was con...
