Vegetation cover over time and space is the result of interactions between vegetation cover and environmental factors. Changes occurred in range covers are caused by matrix dominance, one of the most important environmental factors. Decision support system (DSS) could be used for determining the rate and importance of each factor. Actually, in methods based on […]
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 […]
Pubescent wheatgrass (Agropyron trichophorum (Link) Richt.) is growing in semiarid regions of Iran at altitude of 500 to 2000 m. Among different grasses growing in Iran, A. trichophorum is relatively resistant to grazing and defoliation as compared to other species of Agropyron genus which are dominant in the most summer rangelands. In Emam Gholi protected […]
