A Semi-empirical Approach Based on Genetic Programming for the Study of Biophysical Controls on Diameter-Growth of Fagus orientalis in Northern Iran

Remote Sensing, 2019
This paper examines the possible ecological controls on the diameter increment of oriental beech (Fagus orientalis Lipsky) in a high altitude forest in northern Iran. The main objectives of the study are computer-generated abiotic surfaces and associated

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.

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.

Effects of altitude and seasonal variation on stem moisture content and radial distribution in Scots pine and Oriental beech

Maderas: Ciencia y Tecnología
The stem moisture content (MC) of living trees governs log weight, drying behavior, preservative uptake, and the susceptibility of timber to checking and decay, while also reflecting the response of the tree to climate.

Integrating multiscale ecological indicators to assess ecosystem functioning in virgin Hyrcanian beech forests

Frontiers in Forests and Global Change
Virgin oriental beech (Fagus orientalis L.) forests of the Hyrcanian region in northern Iran are among the last remnants of temperate old-growth ecosystems worldwide, yet their ecological benchmarks remain poorly defined.

Decay dynamics of oriental beech (Fagus orientalis Lipsky) and hornbeam (Carpinus betulus L.) deadwood in mixed beech stands

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.
