Création d'un référentiel écologique pour l'évaluation du succès d'opérations de réhabilitation de zones humides

Abstract : This work deals with the creation of an ecological reference for the assessment of the success of wetland rehabilitation. The experimental sites are cultivated. Globally, the objective of rehabilitation is to restore the wetness of sites, and their functions. Parameters were selected for the follow-up and the evaluation of sites: soil organic matter, bulk density, pH, vegetation. They were measured on the experimental sites but also on "ecological references", which will serve as point of comparison to assess the success of the rehabilitation. It was decided to build two reference types : a twin site which represents the potential of the experimental site, and a reference composed of various undisturbed sites. The results showed that twin sites are healthier than experimental sites, with however some nuances. The reference panel reflects a range of variability of the parameters, and allows to place experimental sites in a more global context.
