Résumé :
|
There has been increasing interest in recent years in reintroducing birds lost from Britain (or parts of it) as a result of human activities. In many respects, reintroduction is an extension of other 'hands-on' approaches to conserving birds, including creation and management of suitable habitats, protection of nests and the provision of food or artificial nest-sites. Carefully considered reintroduction projects can be expensive and take many years to plan, implement and monitor but, in addition to restoring the species in question, may have substantial benefits for a wide range of wildlife. In contrast, poorly planned or inappropriate projects can be detrimental to wildlife. Current legislation is, we believe, in need of revision to ensure that future reintroductions achieve their objectives and are of a high standard in their implementation. Case studies are used that illustrate the achievements of well-organised bird reintroductions in Britain and to highlight: some of the problems that can arise. Finally, we look ahead to the role that reintroductions could play in the future conservation of British birds.
