this study was carried out to investigate the effective environmental factors in the distribution of vegetation in zirkouh rangelands of qaen. after delimitation of the study area, sampling of soil and vegetation were performed using randomized- systematic method. vegetation cover was recorded by using braun-blanquet combined abundance-cover scale in each sample. within each sample, one profile...

abstract this paper presents a quantitative account of vegetation–environmental factor relationships in arid rangelands. vegetation cover was recorded using braun-blanquet combined abundance-cover scale in each quadrat. within each quadrat, one profile was dug and soil samples being taken at 0-20cm and 20-100cm depths. under study physical-chemical characteristics included texture, lime, organi...

the aim of this research was to study the relationships between presence of plant species and environmental factors in garizat rangelands of yazd province and providing their predictive habitat models. after delimitation of the study area, sampling was performed using randomized-systematic method. accordingly, vegetation data including presence and cover percentage were determined in each quadr...
