Fermentation in the rumen of cattle produces methane (CH4). Methane may play a role in global warming scenarios. The linking of grazing management strategies to more efficient beef production while reducing the CH4 emitted by beef cattle is important. The sulfur hexafluoride (SF6) tracer technique was used to determine the effects of best management practices (BMP) grazing compared with continu...

We investigated the impact of pastoral management on birds in subtropical grassy eucalypt woodland in southeastern Queensland, Australia, where the patterns of land management have made it possible to disentangle the effects of livestock grazing from those of tree clearing. We recorded changes in bird species composition, density, and relative abundance across two woodland habitat types (ripari...

Overgrazing is considered one of the key disturbance factors that results in alpine grassland degradation in Tibet. Grazing exclusion by fencing has been widely used as an approach to restore degraded grasslands in Tibet since 2004. Is the grazing exclusion management strategy effective for the vegetation restoration of degraded alpine grasslands? Three alpine grassland types were selected in T...

In the western United States, livestock grazing often co-exists with recreation, cultural resource management and biodiversity protection on federal and state protected rangelands as well as on many local government open space areas. While the value of livestock grazing for managing rangeland vegetation to reduce fire fuel loads and improve wildlife habitat is increasingly recognized by resourc...

owing to the importance and necessity of identifying soil properties in arid rangeland management, and the variableeffects of different kinds of herbivores on soil, this study compares some of the physical and chemical properties ofsoil between two regions experiencing livestock and wildlife grazing in the desert rangelands of kalmand-bahadoranin yazd province. the key areas in two regions expe...

We assessed the relationship between riparian management and stream quality along five southeastern Minnesota streams in 1995 and 1996. Specifically, we examined the effect of rotationally and continuously grazed pastures and different types of riparian buffer strips on water chemistry, physical habitat, benthic macroinvertebrates, and fish as indicators of stream quality. We collected data at ...

Experts were interviewed on the grazing preferences of sheep in upland vegetation types and on the responses of plants to grazing. A qualitative model of direction of change in species abundance given different seasonal sheep grazing management regimes was constructed with the expert information. The model was tested against empirical data of sward responses to summer-only grazing. The approach...

Widely -contrasting stocking rates and grazing schedule treatments were imposed upon a Mediterranean herbaceous community in northern Israel. Botanical composition was monitored for 3 years. The vegetative community was found to be highly resilient to the treatments. Perennial grasses and legumes were among the resilient plants. These results are consistent with the view that Mediterranean ecos...
