During two years, the medicinal plants that have been collected […]
In order to estimate the nutrient value of three dominant range species; Festuca ovina, Trifolium montanum and Alopecurus textilis via proximate analyses and gas production technique, samples were collected in three stages during grazing period from 26th May to 1th September in six areas of Sabalan Mountain in North West of Iran. Results showed that […]
The genus Thymus is perennial medicinal plants belong to the Lamiaceae family that is used for different propose in pharmaceutical industry. Environmental stresses, particularly salinity, are considered as the major factor reducing plant growth. The purpose of this study was to investigate the effects of salt stress on germination characteristics and seedling morphology in two […]
Classifying remote sensing imageries to obtain reliable and accurate Land Use/Cover (LUC) information still remains a challenge that depends on many factors such as complexity of landscape especially in arid region. The aim of this paper is to extract reliable LUC information from Land sat imageries of the Pishkouh watershed of central arid region, Iran. […]
The aim of this research was to investigate the effect of index species, Astragalus ammodendron on the associated plants of Agropyron tauri and Bromus tomentellus from different aspects in Shazand rangeland in southwest of Markazi province. The effects of species density and distribution pattern and then index species on the soil properties were studied. Based […]
Renewable natural resources are the wealth that not only belongs to the current generation but also to future generations. Diversity in rangeland user viewpoints and policy makers has caused these lands to face some damages. This study was conducted to compare viewpoints of ordinary members as rangeland users, and board of directors as executives of […]
Today, in the rangeland management science and determination of range capacity, accurate and true information about range production is crucial.

Awareness of the effects of fire on various aspects of an ecosystem after the fire, is important for range management. Changes in soil physical and chemical properties caused by fire can be the cause of changes in the vegetation. In this study, effects of fire on physical and chemical characteristics of soil were investigated. This […]
Soil salinity is one of the important factors which can influence the growth and distribution of plant species. Saline and alkaline rangelands of Golestan Province, Iran with low-deep underground water level are considered as a halophyte plant species growing area. Attempts have been made to determine soil salinity and its relationship with Frankenia hirsuta L. […]
