For thousands of years grazing was superimposed on abiotic conditions, which have been strongly influenced by human impact. This includes the change from la

This quintessence was captured by many seventeenth century painters, who emphasized the sky with its clouds over near-treeless landscapes. To many a citizen of tod

Spontaneous Order and the Utopian Collectiveans have altered the natural landscape (Chapters 2 and 3). Grazing by livestock is one of the main instruments that forged the traditional preindustrial landscape. This chapter therefore sets out to elucidate the impact of grazing on the development of semi-natural landscape patterns in prehistoric

This list is certainly not complete but it allows some generalizations. Grazed areas harbour pioneer species, including annuals and biennials that have to establish from seedli

Matthew J. Taylor,Michael K. Steinbergabout (Figure 6.1), direct competition may take place for resources important to other fauna. Indirect effects are the result of changes in the structure and the species composition of the vegetation, mainly through the foraging process. The effects are mediated through species-specific characterist

In poor ranges wildlife populations are often said to be limited by environmental conditions. Such a claim necessitates a good definition of the word ‘limiting’ and of the nature of the limitatio
