fire, as a natural ecological disturbance factor in forest, this study located in the marivan region, northern zagros forest, and western iranian state of kurdistan. in each burned and unburned area 30 circle sample plot (1000 m2) were collected by randomized–systematic method in the 100×200 m net (in total 60 plots). in every sample plot the kind of species, number of tree, the height of coppi...

The authors propose that a heat-driven circulation from the Zagros Plateau has a significant impact on the climate of the Middle East Plain (MEP), especially summertime winds, air temperature, and aridity. This proposal is examined in numerical experiments with a regional climate model. Simulations in which the Zagros Plateau was assigned a highly reflective, “snowlike” albedo neutralized the h...

In this paper the geometrical relationship of the folds which exist in the Folded Zagros Mountains, including Asef Mountain (northern Iran), were studied. The southern and western zones of the Zagros Mountains are called the Folded Zagros. These zones extend approximately 1,375 km in length with a width ranging from 120 to 250 km. Asef Mountain is located in northern Shiraz (from northern Sarda...

The Zagros forests (west of Iran) have been highly exploited in recent decades by human impacts. Easy access, abundance and variety of valuable forest yields have led to population growth density, creation of new residential areas and deforestation activities. In order to determinate the distribution and rate of deforestation from 1995 to 2006 by using the satellite imagery (IRS-1C and  LANDSAT...

Assessing the Plant Communities Changes by Effects of Vegetation Type, Physiography and Soil in Central Zagros Forest

Estimation of the Economic Value Soil Nutrition Protection in Zagros Forest Ecosystems (Case Study: Noujian Watershed Khoramabad)

Spatial pattern of trees can possibly indicate stand history, population dynamics, and species competition. This research was investigated in the Chahartagh forest reserve, Ardal region, chaharmehal and Bakhtiari Province, Central Zagros forest, and southwest Iranian state. In this study 53 hectare of the study area was selected and perfect inventory.  Information includes the position and kind...

physiological factors have effects on most forest parameters such as forest classification so that understanding knowledge about this subject is important to manage forests. the forests of sorkhake-sanjabi village with area of 1645 ha located in eslam abad city, kermanshah province, iran were selected. 23 sample plots with rectangular shape (40m*50m) were selected and the species, origin of spe...
