Résumé :	The French Atlantic coast plays only a marginal role within the wintering area of Bar-tailed Godwit Limosa lapponica. Winter figure in January (mean annual number of 7,400 birds in 2000-2009) represents hardly 6% of the estimated total number. Winter visitors are found nearly exclusively along the coasts of North Sea, Channel and Atlantic. The analysis of census during the last thirty years shows that numbers are more or less stable despite a low decrease in the 1990s. The species distribution is mainly linked to the size of the used sites (functional unit) and to that of protected areas. Meteorological factors play a minor role in the species distribution. Winter numbers censused in the last five years (2005-2009) amounted to 8,000 birds. This means that at the 1 %, a site of national importance must harbour at least 80 birds (criterium 6 of Ramsar convention). Thirteen sites are thus of national importance but no French site is of international importance. The Bar-tailed Godwit is a species sensitive to disturbance. A suitable management of protected areas must be enhanced to maintain or to favour the species occurrence.
