Large herbivores as key factors for nature conservationstock and, therefore, the connection with nature conservation is not obvious or free from ambiguity. Thus, the first purpose of this introduction is to indicate the links between the two issues. The recent discussion in the journal . over the relationship between livestock grazing and nature conserv

Effects of human interference on the landscape with special reference to the role of grazing livestoans 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

The impact of grazing on plant communitieses in which large herbivores were excluded from previously grazed landscapes/plant communities are summarized in Table 5.1. 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

Effects of large herbivores upon the animal communityabout (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

Wild herbivores, such as roe deer (.), red deer (.), hare (.), rabbit (.), herbivorous birds and insects, are not included in this chapter. Although such herbivores may have a considerable impact on the vegetati

Habitat quality and the performance of large herbivoresis well known that quality differences between areas or habitat types affect the performance of animals. 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
