Habitat conditions and plant-environment relationship in some arid and semi‌arid lands character plants (case study: Shahriyar Rangelands, Tehran Province)

Abstract

In order to obtain an optimum management of natural resources, determination of variables that control plant presence and distribution is needed. In the present research, the relationship between some character plants of drylands and some soil and environmental variables were investigated. After primary survey and selection of main plant species, sampling was done in each vegetation type within 3-4 transects (200 m length) by randomized-systematic method.
