Abstract : Bird disturbance is one of the impacts related to human frequentation on natural sites. It results both from the destruction and the fragmentation of natural habitats, and from the increase of human frequentation on these spots. If human/bird cohabitation has been possible for a long time thanks to widespread natural habitats and a lower anthropogenic pressure, it has now become more complex and sometimes problematical when disturbance occurs on a regular basis and when rare and/or endangered species are concerned. This thesis aims to assess the issue of bird disturbance within the geographical framework of Brittany, France. Firstly, an extensive scientific bibliographic synthesis coupled with a regional survey enabled us to highlight the complexity of the concept of disturbance, its biogeographical characteristics as well as the difficulties faced by conservation area managers when dealing with this issue in situ. Secondly, this thesis aims to carry out a methodological and pluridisciplinary study of human/bird interactions through the monitoring of two working sites, bringing together the skills and knowledge of different geographers and biologists. Based on a reading of the Natura 2000 legislation, our methodology allows an assessment and a quantification of the loss of natural habitats in wintering waterbirds resulting from human frequentation, thus, enabling the identification of human activities regarded by European legislation as “significant disturbance”.
