بررسی آت‌ اکولوژی گونۀ Stipagrostis pennata در ماسه‌زارهای روداب

Discovering ecological factor of desert indicator specific species is considered as an applied study aiming to shed light on edaphic and ecological factors influencing the very labor ever and their management. In the Land of sandy desert soil conditions are very compatible with special herbs, growing and one of the most important species is Stipagrostis pennata That of the family Poaceae. In the current research climate of the study area is cold dry. A random systematic design has been applied in 4 sites called A, B, C, and D within a distincthabitat of S. pennanta. The most important ecological factor for the growth and distribution of Sand plain desert region as a dominant species and communities of habitat, species Soil compatibility with sandy hair root sheath and the development of the root system in wide area network. Studies have shown that in addition to the impact of the consolidation of sands. The results show that there is a direct relationship between the amount of nitrogen and growth properties off S. pennanta.
