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...

this research was carried out based on systematic analysis approach for evaluation of ecological resources capability of kasilian representative catchment for agricultural land use. the study area is located in southern of mazandaran province. in this study we used topography digital data, paper maps, climatology data, satellite images and gis, database and spreadsheet software. the process of ...

in this study, we focused on detailed studies on micromorphological and mineralogical properties of three types of peat and swamp, to compare these different ecological area together. to achieve this goal, samples from a highland peat swamp (ghaleh-ghafeh ps), a peat swamp forest (suteh psf) and a costal swamp (galougah cs) in golestan province, north of iran have been considered. these studies...

the present study was carried out during a one year period in 2012-2013 in order to investigation of seasonal density and diversity of diplopoda in a hyrcanian forest (semeskandeh forest) in northern iran. for these purpose, some forest soil sampling were done in two mounth intervals and the samples were collected from leaf litter (ol,f,h), the 0-3 cm and 3-6 cm of soil layer (ah). a total of 7...

the effect of fire was investigated on some soil chemical properties of forest area of baghe shadi herat- yazd province. to perform the experiment, 18 profiles of soil in control area and 7 profiles from each of burned areas were dug and samples of two depth (0-15 and 15-30) in total of 64 samples were collected. results showed effect of the area was significant in organic matter and carbon per...
