Recognition of habitats and conditions of species presences in different situations can be effective in proper utilization of vegetation. Little is known about the vegetation composition of Boralan Mountain region located in North West of Iran in the border of Turkey and Azerbaijan with the altitude range of 800-2000m. The aim of this study therefore […]
Abstract. The purpose of this study was to investigate the effects of topographical factors on the classification of grassland plant communities in the rangelands of Ghorkhud, Northern Khorasan Province, Iran. For sampling, land units were specified. A floristic list was prepared using minimal area method based on the nested plot (Braun-Blanquet method). 116 10m2 furrows […]
One of the main objectives of ecosystem management is to preserve the species diversity. Many researchers regard higher species diversity as the stability of ecological systems. The aim of this study is to investigate the stability and relationships between topographical factors with diversity indices in Ghorkhud mountainous rangeland in northern Khorasan province, Iran. For data […]
Medicinal plant species constitute a considerable part of the flora in Iran and play a major role in the composition of plant communities. Therefore, it is necessary to recognize the factors leading to the establishment and distribution of vegetation. For data sampling (2012), land units were specified. The plot size was determined using minimal area […]
There is less published research on ecosystems of forested rangeland in Iran. This research was conducted to investigate the forested rangeland area based on legal definition via comparison of indices species richness, diversity, and morphology of the trees and shrubs in Sabzkouh watershed, Chaharmahal Bakhtiari province, Iran. Quantitative characteristics of trees and shrubs were measured […]
Most of rangeland soils are limited in their ability to supply adequate nutrients to plants. Soil conditioners have been shown to alter soil fertility and plant characteristics. This investigation aimed to evaluate the influence of two soil conditioner on nutrition value of N. schoberi and A. podolobus. For this, two separate experiments for each species […]
