Conserving living landscapes: investigating the impacts of livestock grazing and assessing rangeland restoration potential in Overberg Renosterveld, South Africa
… Historically, large herds of indigenous grazing mammals roamed these landscapes. Today the Overberg's agricultural lands are fragmented by land cover change and divided by fences. In the contemporary landscape animals, largely domestic livestock, and plant resources are closely coupled, …

Living in the moss. Mesofaunal communities of Racomitrium lanuginosum in Icelandic rangelands
… In northern rangelands, large herbivores such as sheep and reindeer can disturb the moss layer by trampling, grazing and waste deposition. However, the effect of large herbivores on the arthropod mesofauna in the bryosphere has yet to be explored. The aim of this study is to contribute to the …

The Impacts of Heather and Grassland Burning in the Uplands: Creating Sustainable Strategies
… peat soils of UK uplands are heavily managed for sheep grazing and recreational shooting. Productivity of these landscapes has been increased through managed burning of the vegetation. Burning has been linked with increases in water colour and inappropriate burning can lead to ‘unfavourable’ …
