L'assèchement des dépressions dunaires du littoral du Cotentin?: mécanismes et propositions de gestion

摘要

The dunes of Lower Normandy are characterized by moist depressions of various sizes. The depressions harbour a rich fauna and habitats, which are therefore of great patrimonial interest. But this environment has for some years witnessed an overgrowth of brushwood. This last one, directly connected to a drying out, worries the managers. The analysis of processes of drying out of dune slacks shows the combination of parameters involved (moisture conditions in the soil, human actions), and thus allows to optimise the patrimonial management of these sites.
