The specificity of the Port of Rouen's territory is to have very spread out spaces along the Seine Valley and located along the river. In view of this situation, the actions carried out by HAROPA - Port of Rouen mainly aim to promote the link with the river by promoting, as far as possible, the development of hydraulic annexes which can serve as a temporary refuge for fish or feeding areas for shorebirds, the development of intertidal estuarine habitats (mudflats, reeds etc) or the creation of wetlands. These restoration actions carried out as part of environmental project measures are intended to contribute, at their level, to the ecological restoration of the estuary.
