To determine the potential habitat of two rangeland species of Salsola rigida and Agropyron trichophorum in Qasr-e-Shirin, Iran, Geographic Information Systems (GIS) and Remote Sensing (RS) techniques were used. At first, several maps (vegetation cover and land uses maps and thematic maps of various organizations) were collected or prepared. For digitizing geology, vegetation and conventional […]
Nowadays, in many rangelands, due to over grazing, and problems that some plants have in germination, the rate of forage production is greatly reduced. So to take advantages of the benefits of such plants, it is necessary to identify and remove barriers of germination and establishment of suitable plants. The present study was designed to […]
Environmental pollution with heavy metals is a global disaster that is related to human activities. This study was conducted to determine the extent of heavy metals accumulation by plant species in Lia industrial city (Qazvin, Iran) and to investigate the remediative capacity of native plant species grown in the contaminated soils. Soil and industrial wastewater […]
This research aims to evaluate the effects of seed scarification on five perennial Astragalus species including A. effusus, A. vegetus, A. subsecundus, A. brevidens and A. cyclophyllon in the field conditions. Seeds were sown after scarification with sandpaper by hand in the field of Homand Absard Rangeland Research Station, Damavand, Iran in autumn in 2008. […]
Rangeland ploughing and cultivation using dry land farming crops may be a major reason for the destruction of natural resources in the semiarid and sub-humid regions which may significantly change the composition and reduce the stability of the affected communities. In present research, an abandoned ploughed site was compared with a nearby reference site in […]
Rangelands are known as one of the main income resources for their exploiters. In the recent century, management of Iran rangeland has undergone vast transformations because of vulnerable socio-economic conditions of pastoralists. A study was done to provide a clear picture of the status and utilization of Aq Qala rangelands via assessing internal and external […]
Knowledge on habitat characteristics and nature of regional vegetation in rangelands is a prerequisite for any planning and proper range management along with sustainable development of renewable natural resources. Rangelands in southern and western highlands of Kashan, Iran are of good vegetation diversity but unfortunately, palatable and desirable species are endangered in recent years. This […]
Understanding the plant species diversity could be used as an important indicator applied for the natural areas management. The aim of this study was to investigate the relationships between soil characterizes with distribution and diversity of plant in vegetation types in Karvan district (located in west of Isfahan province). For this purpose, three vegetation types […]
Tajikistan is a hotspot of plant and animal species diversity and endemism and is important for the conservation of biodiversity on a global scale. The country is located at a biological crossroads. Species from Central and Northern Europe, Central Asia, the Middle East, and North Africa mingle here with endemics found nowhere else. The richness […]
Flood disaster is considered as a major natural hazard due to its devastating effects on the affected areas. Determining the flood vulnerable areas is important for decision makers in order to perform planning and management activities. Geographical Information System (GIS) is integrated with Multi Criteria Decision Analysis (MCDA) used to analyze the flood vulnerable areas. […]
