Calculating the factor of safety (FS) as slope stability is necessary to prevent environmental damage. Therefore, this paper aims (i) calculate FS using limit equilibrium approaches and Slide software (ii) investigate slopes according calculated (Janbu Bishop methods) status different sites in study area (Hyrcanian forest Iran). Six landslides were selected along road by a field survey. Landsli...

Besides Quercus, Acer L. genus is the largest tree in Northern Hemisphere and consists of about 124–156 species. High morphological molecular variability has led to infra-specific complexity within most species this genus. In Iran, cappadocicum subsp. Gled. distributed eastern western parts Hyrcanian forests. study, three leaf-morphotypes A. were identified during sampling a forest located regi...

Estimating the diameter increment of forests is one most important relationships in forest management and planning. The aim this study was to provide insight into application two machine learning methods, i.e., multilayer perceptron artificial neural network (MLP) adaptive neuro-fuzzy inference system (ANFIS), for developing models Hyrcanian forests. For purpose, diameters at breast height (DBH...

Aim To analyse the biogeographic patterns of Temperate Deciduous Forests (TDFs) in Western Eurasia based on different life-forms and forests layers explore their relationships with current climate, Last Glacial Maximum (LGM) climate topography. Location Eurasia. Taxon Vascular plants. Methods We delimited nine regions encompassing variability TDFs collected 1000 vegetation plots from each. deco...

Parrotia persica is one of the most notable endemic relict tree species growing in Hyrcanian forest at southern Caspian Sea. The recent discovery sibling subaequalis, occurring temperate forests south-eastern China, offers opportunity to compare their morphology and ecological preferences dig deeper into paleophytogeographic history genus from a perspective. Since pollen these would be essentia...

forests are an important economic source for human and have key role in nutrient cycle, hydrology and ecosystem performance, any interference in this vital ecosystem causes to damage to forests. mechanical logging and road construction in forest areas have led to much soil compaction. soil physical and chemical properties were studied in parts of road and non-road in the darabkola forest of ira...

Iran, a 4-season land in the world, is located in semi-arid part of Asia. There are several geographical climates in this country, which are the main causes for the existence of diverse ecological conditions. In the north, where the Caspian Sea meets the land, there are three provinces. One of these, Guilan province, (the studied area) is located in the southwest of the Caspian with different g...
