Vernal pools in the Sacramento Valley are essentially islands of native flora among a grassland composed primarily of exotic annual species. In managing the vernal pool landscape to sustain these islands of native flora, the integrity of the landscape’s hydrology must be maintained. One management decision that may indirectly affect hydrology is complete rest from grazing. Although the native v...

Livestock have been a key factor in the development of civiliiation, hut what will their role be in the future and how should the science of rangeland management change to meet the challenges of the future? In this paper I look at current grazing management in the contest of paradigm shifts and scientific revolution. The impact of livestock on rangelands occurs primarily because livestock selec...

Highlight: Preferences of white-tailed deer to various grazing management systems now being tested at the Texas A&M University Agricultural Research Station, Sonora, were evaluated on the basis of deer density and economic returns from hunting. Hunter success was evaluated on the basis of several factors. White-tailed deer definitely preferred a rangeland grazed under a system which included a ...

BACKGROUND With world food demand expected to double by 2050, identifying farming systems that benefit both agricultural production and biodiversity is a fundamentally important challenge for the 21(st) century, but this has to be achieved in a sustainable way. Livestock grazing management directly influences both economic outputs and biodiversity on upland farms while contributing to potential...

Rangelands are the most important ecosystem for carbon sequestration. Knowledge of plant response to grazing is one of important requirements for rangeland management. Stocking rate is one of main factors in destruction of the vegetation cover in rangeland ecosystems. Livestock grazing has the potential to substantially alter carbon storage in grassland ecosystem. This study examined the effect...

Beyond grazing, managed grasslands provide ecological services that may offer economic incentives for multifunctional use. Increasing biodiversity of plant communities may maximize net primary production by optimizing utilization of available light, water, and nutrient resources; enhance production stability in response to climatic stress; reduce invasion of exotic species; increase soil OM; re...

Maintaining or enhancing the productive capacity and resilience of rangeland ecosystems is critical for the continued support of people who depend on them for their livelihoods, especially in the face of climatic change. This is also necessary for the continued delivery of ecosystem services derived from rangelands for the broader benefit of societies around the world. Multi-paddock grazing man...

Rangeland management plan is one of the major means of management and utilization of rangelands in Iran. The formulation of these plans for the rangeland users should be studied from the ecological and socio-economic points of view. One of the main envisaged activities in almost all the management plans is the grazing system. An experiment was used to study the effects of three deferred grazing...

Dairy systems predominantly based on rotational grazing are notoriously hard to manage. In order to ensure profitability, this type of production requires quite good organisation, planning, and operating capability on the part of the farmer. A simulation-based decision support system, called SEPATOU, has been developed for this purpose. At the core of the decision support approach lies an expli...

Grazing of Livestock is one of the factors having influence on the structure and dynamics of the range land vegetation. Grazing management is a vital factor to control the intensity of the rangeland ecosystems degradation. In this study, plant functional traits and diversity and richness properties were used to assess the vegetation response to different grazing intensities. This was done in No...
