Large Herbivores and the Design of Large‐Scale Nature Reserves in Western Europe

Abstract

Nature conservation in densely populated areas, as in western Europe, faces the continuous loss and fragmentation of suitable habitats for wild species. Current conservation measures have not been successful in countering this threat to biological diversity, so a new concept for nature conservation is required. I propose using the habitat requirements of large herbivores as a key to the design of large‐scale nature reserves. Large herbivores can have a significant influence on vegetation composition and thus act as keystone species. Moreover, they require large tracts of land and can be considered an umbrella species group for the preservation of other plants and animals. I review the present status of nature reserves in the European Union concerning size distribution and the occurrence of large herbivores and their predators. I argue that habitat fragmentation and the increased management costs of maintaining seminatural areas necessitate an enlargement of existing reserves, a process‐oriented management approach, and a minimization of human influence for the long‐term preservation of biological diversity.
