Biodiversity drivers in European and Oriental beech forests
Buchenwälder sind globale Refugien und Hotspots der biologischen Vielfalt weltweit und können einenhohen Anteil an endemischen und reliktischen Arten beherbergen. In Europa gibt es nur noch einigeReste alter europäischer Rotbuchenurwälder (Fagus sylvatica), die jetzt als "Alte und ursprünglicheWälder der Karpaten und anderer Regionen Europas" zum ...

Diameter and height increment process of oriental beech (Fagus orientalis) in natural Caspian forests; Kelardasht region [PDF]
تحقیقات جنگل و صنوبر ایران, 2007 The development stages in the natural forests run very slowly, which are not easy to recognize them within a short period of time. The duration of development of a stand and transition from one stage to another varies among the forest communities.

Generalized height-diameter models for Fagus orientalis Lipsky in Hyrcanian forest, Iran
Journal of Forest Science, 2016 In this study, 39 generalized height-diameter prediction models were developed for Oriental beech (Fagus orientalis Lipsky) in the Hyrcanian forest in Iran. Data were collected from 75 permanent sample plots in uneven-aged stands of F. orientalis.

تحقیقات جنگل و صنوبر ایران, 2014 Due to their significance for carbon sequestration and ecosystem management, information on decay dynamic of deadwood and its total decay time are of great importance to ecologists and forest managers. This study was conducted in Kheirud forest of Nowshahr to study the decay process of beech and hornbeam deadwood.

Determination of Surface Roughness Based on the Sanding Parameters of Oriental Beech Wood
BioResources, 2018 This study demonstrated the strength of a theoretical model founded on the Box-Behnken experimental design method to determine the surface roughness (Ra parameter) of solid Oriental beech (Fagus orientalis Lipsky) wood. The working parameters (sanding belt grit size of 60 to 100, feeding speed of 4 m/min to 10 m/min, and sanding cutting depth of 0.1 mm
