Résumé :	The French overseas territories have rich avifauna, particularly with endemic species. Protected areas have been designated in those regions, such as National Parks, Nature Reserves, etc. However, the Natura 2000 scheme, derived from EU Birds and HabitatsFauna-Flora directives, is not applicable in these extra-peripheral European regions. Nevertheless, the Grenelle Environment Forum held in 2007, encouraged to provide overseas territories with a similar initiative based on biodiversity inventories and hotspot identification. Within the framework of the European program LIFE+ CAP DOM (2010-2015), we developed a method for identifying Important Bird Areas on Reunion Island in seven steps. (1) The method is based on criteria developed for the identification of IBAs of EU interest on one hand; and on the other hand, on inventory criteria of the R6seau Ecologique habitats des DOM (Ecological network for French overseas territories habitats). 8 criteria (O1-O8) have been defined to select local IBAs, considering the red list classification of local species, following the IUCN threat criteria. A list of 21 trigger species (2) has been established according to these criteria. The gathering (3) of available bird location data allowed the identification of 26 IBAs on Reunion Island by means of mapping analyses (4). Anticipating an upcoming implementation of sites management, we created a rating system (5) to develop a list of 8 "best" IBAs. The presence of trigger species was confirmed by field visits (6) and a spatial delimitation of the 8 areas was proposed (7), according to habitat delineation, topography, hydrography and infrastructure.
