Drought is common in rangeland environments and an understanding of its impacts on the structure and function of rangeland ecosystems is paramount for developing effective management strategies. This research was the second of a series of studies investigating the impacts of varying seasonal droughts on northern Great Plains rangelands. Research was conducted on native rangeland during the 1998...

Introduction: Rangeland ecosystems provide multiple ecosystem services, including feed resources for wild and domestic herbivores in semi-arid areas. However, under the ever increasing environmental changes, the impact of rainfall variability on the productivity and vegetation dynamics of rangelands are the great challenges that pastoral community are facing today. As a result, the potentials o...

Soil characteristics and functions are critical determinants of rangeland systems and the ecosystem services that they provide. Rangeland soils are extremely diverse, but an emerging understanding is that paradigms developed in more mesic forest ecosystems may not be applicable. Vascular plants, biological soil crusts, and the soil microbial community are the three major functional groups of or...

rangeland plans as an management option is subject that by giving range to beneficiaries beneficiaries will be identified in the plans whit specific programs. the purpose of this study is to identify factors affecting the performance of rangelands schemes and consequently to rank the projects in razavi khorasan by identified factors. six original schemes in razavi khorasan were selected for thi...

The need to balance biodiversity conservation with sustainable development, though widely agreed upon, is elusive in practice. Human societies are increasingly disconnected from the ecosystems which support them. The loosening connection and growing scientific acceptance that ecosystems are complex, dynamic, non-linear systems pose new challenges for rangeland monitoring. Consequently, although...

Pasture and grazing land in the southern central Great Plains is being invaded by woody species, especially eastern redcedar. As a result of plant encroachment, cattle production on native rangeland becoming less profitable because stocking rates must be decreased. Eastern redcedar encroachment can controlled management, herbicide use, prescribed fire, mechanical control mixed species grazing. ...

Rangelands provide the main forage resource for livestock in many parts of the world, but maintaining long-term productivity and providing sufficient income for the rancher remains a challenge. One key issue is to maintain the rangeland in conditions where the rancher has the greatest possibility to adapt his/her management choices to a highly fluctuating and uncertain environment. In this stud...
