“…During the conversion from NMG to UF, PF, and PP, the vegetation cover and soil properties were changed according to how the land conversion was managed. Variations in the environment due to land-use conversion have a direct influence on the microbial community inhabiting the soil (Zhang et al, 2014;Mendes et al, 2015). In the Horqin region, the land-use conversion of NMGs usually involves plowing and harrowing the soil and the cultivation of crops or planting trees.…”

Abstract. The conversion of natural grassland into agricultural fields is an intensive anthropogenic perturbation commonly occurring in semi-arid regions, and this perturbation strongly affects soil microbiota. In this study, the influences of land-use conversion on the soil properties and bacterial communities in Horqin Grasslands in Northeast China were assessed. This study aimed to investigate (1) how the abundances of soil bacteria changed across land-use types; (2) how the structure of soil bacterial community was altered in each land-use type; and (3) how these variations were correlated with soil physical and chemical properties. The variations in diversities and compositions of bacterial communities and relative abundance of dominant taxa were detected in four distinct land-use systems, namely, natural meadow grassland, paddy field, upland field, and poplar plantation, through high-throughput Illumina MiSeq sequencing technique. Results indicated that land-use changes primarily affected soil physical and chemical properties and bacterial community structure. Soil properties, namely, organic matter, pH, total N, total P, available N and P, and microbial biomass C, N, and P, influenced the bacterial community structure. The dominant phyla and genera were almost the same among the land-use types, but their relative abundances were significantly different. The effects of land-use changes on the structure of soil bacterial communities were more quantitative than qualitative.

“…Rangelands are important for biodiversity conservation and livestock production and support the livelihoods of millions of peoplemany of them among the world's poor (Campos et al, 2016;Nadal-Romero et al, 2016). However, many rangelands are severely degraded because of anthropogenic and climatic factors, with grave consequences for people and wildlife (Lu et al, 2015;Zhang et al, 2016). Poor grazing management is often cited as a major contributor to rangeland degradation (Lesoli, 2011;Kiage, 2013;Carter et al, 2014;Nadal-Romero et al, 2016;Tóth et al, 2016) and can seriously impair rangeland sustainability (Ibáñez et al, 2014).…”

Vegetation, Wildlife, and Livestock Responses to Planned Grazing Management in an African Pastoral Landscape

2017

Rangelands are vital for wildlife conservation and socio‐economic well‐being, but many face widespread degradation because in part of poor grazing management practices. Planned grazing management, typically involving time‐controlled rotational livestock grazing, is widely touted as a tool for promoting sustainable rangelands. However, real‐world assessments of its efficacy have been lacking in communal pastoral landscapes globally, and especially in Africa. We performed landscape‐scale assessment of the effects of planned grazing on selected vegetation, wildlife, and cattle attributes across wide‐ranging communally managed pastoral rangelands in northern Kenya. We found that planned grazing enhanced vegetation condition through a 17% increase in normalized difference vegetation index, 45–234% increases in herbaceous vegetation foliar cover, species richness and diversity, and a 70% reduction in plant basal gap. In addition, planned grazing increased the presence (44%) and species richness (53%) of wild ungulates and improved cattle weight gain (>71%) during dry periods when cattle were in relatively poor condition. These changes occurred relatively rapidly (within 5 years) and despite grazing incursion incidents and higher livestock stocking rates in planned grazing areas. These results demonstrate, for the first time in Africa, the positive effects of planned grazing implementation in communal pastoral rangelands. These improvements can have broad implications for biodiversity conservation and pastoral livelihoods. Copyright © 2017 John Wiley & Sons, Ltd.

“…Land degradation is a consequence of the mismanagement of the natural resources. Usually, the abuse or misuse of those resources is because of agriculture, grazing, or mining (Bruun et al, 2015;Masto et al, 2016;Zhang et al, 2016). However, the human activities can be sustainable and some strategies as mulching, cash crops, low intensity grazing, or organic farming can help to achieve the sustainability (Costantini et al, 2015;Li et al, 2016;Lu et al, 2015;Prosdocimi et al, 2016).…”

Evaluating the Role of a Protected Area on Hedgerow Conservation: The Case of a Spanish Cultural Landscape

et al. 2016

Hedgerows are key features in agricultural landscapes performing diverse functions that are both economically and ecologically significant. Here, we quantify how the characteristics of a relict hedgerow network of a Spanish cultural landscape (Guadarrama mountains in the north of Madrid region) have changed over a single decade both inside and outside the boundaries of a Protected Area, the aim of which is to conserve cultural uses and biodiversity. A gradient of abandonment of pasture systems was detected, including a decline and loss of woody species from hedgerows associated with grazed areas towards shrub encroachment zones. These tendencies were similar inside and outside the boundaries of the Protected Area. The results highlight the management weaknesses of the Protected Area in order to achieve its objectives. Based on the results, we propose to include a specific conservation status for hedgerow landscapes in the regulatory framework of Spanish protected areas. Copyright © 2016 John Wiley & Sons, Ltd.
