Abstract

The aim of this research is to assess the ecological needs of Ephedra major as a medicinal and forage species and important for soil and water conservation in rangelands of Bojnourd. In the site, the studies were climatically characteristic, geology, stand type, co-dominant plant and vegetable variation, Estimating biomass, physical and chemical analyses of the soil. The results indicated that Ephedra major could be adapted for regions with semiarid-cold climate to altitude climate, annual rainfall average of 332. 9 mm and annual temperature average of 9. 82 c . Ephedra major have dispersed in north, south, east and west slope and altitude 1400-2520 m of sea level in mountainous areas. The Soils physical and chemical analyses showed that the soil is very shallow with sandy-loom texture, Ph= 7. 75, Ec= 55. 88 μ s/cm and lime. The stand type was Artemisia aucheri-Festuca ovina and the co-dominant plants were over 86 species. Average of canopy covers and density were 2. 16 and 346 shrubs in hectare respectively. Principal component analysis (PCA) indicated that the variables of precipitation, saturation moisture percentage, pH, potassium, calcium and sand had significant correlations with the first axis and explained the 49. 84% variation. For the second component, the percentage of organic matter and nitrogen were more important traits and explained the 27. 94% variation. Because of the high ability of the species to adapt itself with hard environmental condition such as high percentage of Caco3, and also its medical and conservation values in arid and semi-arid regions, it can be used for proper management strategies, reclamation and preservation of its habitats.
