a primary uses from iran rangelands is livestock grazing and the major livestock is sheep. sheep grazing on the slopes above 60%, because of using a lot of energy for grazing operation, caused to not only reduces livestock performance but also increases the risk of erosion. sheep grazing in an area where more than five kilometers away from water sources, due to the prolongation of the march rou...

The role of ungulate grazing in shaping rangeland ecosystems is well known relative to other important plant-animal interactions such as pollination, seed dispersal, granivory, and belowground herbivory. Successful rangeland revegetation may be enhanced by strategies that favor certain groups of animals and discourage others. Many perennial forbs and shrubs require animals for successful pollin...

Conservation policy often incentivizes managers of human-impacted areas to create landscape heterogeneity to maximize biodiversity. In rangeland, patchy disturbance regimes create landscape heterogeneity (patch contrast), but outcomes of heterogeneity-based management are rarely tested for a universal response. We analyzed four habitat variables – vegetation structure, plant functional group co...

We investigated experimental warming and simulated grazing (clipping) effects on rangeland quality, as indicated by vegetation production and nutritive quality, in winter-grazed meadows and summer-grazed shrublands on the Tibetan Plateau, a rangeland system experiencing climatic and pastoral land use changes. Warming decreased total aboveground net primary productivity (ANPP) by 40 g x m(-2) x ...

The most important decision for successful range management is setting a proper stocking rate. The stocking rate affects rangeland health and productivity, livestock production, and economic returns. Because of its importance, much rangeland research has focused on answering the question, "what is the proper stocking rate?" However, like many important questions in life, it is not easily answer...
