biodiversity plays a crucial role in stability and productivity of natural ecosystem. the main goal of this research was to classify ecological groups in steppe rangeland and investigate their relationships with plant diversity indices. therefore, fifty different land unit tracts (lut) were identified in khod-neuk basin, yazd province, iran, in 2010. vegetation and soil samples were taken in th...

forests and rangelands are the most important natural ecosystems which provide many economic benefits to the society due to their biodiversity and ecological functionalities. dashtenaz wildlife refuge, sari, is a sylvan region, covering 55 ha of rangeland with abundant diversity, is refuge of an endangered species of deer called dama mesopotamica. in this study, contingent valuation method (cvm...

This study aimed to identify the most important physical variables affecting the distribution of four range plants species (Tamarix aphylla, Calligonum comosum, Prosopis spicigera and Salsola rigida) habitats and to prepare potential habitat map of the species using Maximum Entropy (MaxEnt) method in rangelands of Jiroft city, Kerman province, located in SE Iran. To this end, sampling of vegeta...

Carbon sequestration in rangeland ecosystems has been identified as a suitable strategy to offset greenhouse gas emissions that information of carbon sequestration hotspots is a good tool to improve rangeland management. Objectives for this study were to assessment potential carbon sequestration in various rangeland types, to identify carbon sequestration hotspots and to study the effective fact...
