Astragalus adscendens as a predictor of rangeland ecosystem functions and services in the Zagros territory residents of Bakhtiari

Introduction:

 One of the most important approaches to understanding the characteristics of each region is its vegetation study. Therefore, identifying the characteristics of vegetation, explaining its services, functions and ecological and economic values can be a suitable guide for the segregation and differentiation of potential regions. Genus Astragalus is one of the plant genera with abundant variety and abundance. This genus has been distributed and growthed in Iran and most parts of the world. One of the most important species of this genus is Astragalus adscendens Boiss. & Hausskn, which is known as the tragacanth plant and the only host of the Psyllid insect that produces an exclusive product called Ghazangbin.

Purpose of the research: 

Plant diversity in rangelands and, consequently, the abundance of animal species can provide diverse service and functional potentials and values. Due to climate conditions and utilization techniques of arid and semi-arid rangelands, this species has become especially important issue.

Methodology :

Due to the review nature of the research, the data collection method has been used in a documentary-library method.Geographical area of research Considering the extent and distribution of A. adscendens in the Zagros region and the territory of the Bakhtiari tribe, it is necessary to study the ecology, geographical distribution and functions of this species.

Results and discussion:

 This study has examined the ecology, geographical distribution, and ecosystem functions and services of A. adscendens.

Conclusion:

 The effective and efficient strategies for the protection and management of this species can be achieved by introducing and identifying the ecological needs and values and functions of the species in the form of ecosystem goods and services and identifying its threatening factors and own Psyllid insect.
