Nature conservation with large herbivores in a restored riparian environment
Restoring damaged or destructed ecosystems became an urgent target for nature conservation of the twenty-first century. Achieving and maintaining habitat diversity is generally the aim in ecosystem restoration, especially in projects associated with rewilding, and large herbivores are important acto...

Restoring damaged or destructed ecosystems became an urgent target for nature conservation of the twenty-first century. Achieving and maintaining habitat diversity is generally the aim in ecosystem restoration, especially in projects associated with rewilding, and large herbivores are important actors in this process due to their role as ecosystem engineers. The influence that large herbivores have on different parts of the ecosystem are, however, not straightforward. In this thesis, I investigated how birds, as indicator species of biodiversity, may be affected by large herbivores in a recently restored floodplain ecosystem on the Rhine Island of the national nature reserve Petite Camargue Alsacienne. My work focused on how numbers of the most abundant songbird species and of birds of different foraging guilds on the restored area are related to the spatiotemporal distribution of cattle and horses that were introduced to the Rhine Island as ecosystem engineers.
