The efficiency of livestock production in shortgrass steppe may be increased by grazing fourwing saltbush (Atriplex canescens [Pursh] Nutt)-dominated rangeland in late fall and/or early spring, but there is a paucity of information concerning stocking rates and animal gains. The objective of this study was to compare the effects of light and moderate stocking rates on weight gains of heifers gr...

Livestock grazing has the potential to substantially alter carbon (C) storage in grassland ecosystem. In this study, we evaluated the soil-plant system C (0-30cm) under three different grazing intensities by yaks (light: 1.2, moderate: 2.0, and heavy: 2.9 yaks/ha) in alpine meadow on the eastern Tibetan Plateau. Soil organic C at 0-30cm depth and total plant components C increased from light gr...

The effect of cattle grazing on the soil nematode and protozoan communities, and on microbial biomass, was measured in Israel’s northern highlands. Three grazing areas were compared: (1) with 1 1 cow ha 1 y ; (2) 0 55 cow ha 1 y ; and (3) control—no grazing for almost 18 years. Soil samples were collected from the upper 10 cm level of each area (n1⁄4 24), in autumn, before the onset of the rain...

A study was conducted to determine foraging efficiency of cattle, mule deer, and elk in response to previous grazing by elk and cattle. Four enclosures, in previously logged mixed conifer (Abies grandis) rangelands were chosen, and within each enclosure, three 0.75 ha pastures were either: 1) ungrazed, 2) grazed by cattle, or 3) grazed by elk in mid-June and mid-July to remove approximately 40%...

BACKGROUND The effects of grazing on soil methane (CH4) uptake in steppe ecosystems are important for understanding carbon sequestration and cycling because the role of grassland soil for CH4 uptake can have major impacts at the global level. Here, a meta-analysis of 27 individual studies was carried out to assess the response patterns of soil CH4 uptake to grazing in steppe ecosystems of China...

This study aims to assess the effect of grazing intensity on vegetation structure, soil nutrient concentrations and soil physical properties. The study was carried out in steppe rangelands of Saveh, Markazi province, Iran. Four sites with four grazing intensities including very high, high, moderate and non-grazed with the same ecological conditions were selected. To study various vegetation and...

A modified litter-bag method was used to measure plant fineroot decomposition in relation to biomass quality in a mixedgrass prairie. Measurements were made during three years on moderately and heavily grazed pastures that had been under cattle grazing for 17 years prior to sampling. Although we found no significant difference in initial fine-root litter quality between grazing treatments, nitr...

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...

Livestock grazing is one of the most important factors influencing the above-ground community composition and structure in a natural grassland ecosystem. Different grazing intensities also have the potential to alter soil C and N storage substantially in grasslands. We conducted a field community study and soil analyses to determine the effects of different grazing intensities on the above-grou...

Finding an optimal balance between livestock production and grazing impact on animal diversity is important for the development of sustainable grazing systems. This paper tests the hypothesis that extensification of grazing management enhances animal diversity. Similar treatments were applied over a period of three years to sites in the UK, France, Germany and Italy. There were three treatments...
