Abstract: This study is about the long term evaluation of the vegetation of Bois-des-Bel peatland, restored by the “moss layer transfer” technique. The communities approach showed different vegetation structure and composition for the reference ecosystem, the non-restored section and the nine years old restored section. However, the restored section had higher abundances of 1) Sphagnum mosses which increased its dissimilarity from the non restored section and of 2) herbaceous species which increased the difference with the reference ecosystem. Traits of herbaceous species found ten years after restoration were different and more uniform than those found in the reference ecosystem, but they seemed to converge toward the latter. For herbaceous species, the former ditches of the restored section had higher traits functional diversity than peat fields ten years after restoration. Thus, the creation of shallow or deep ponds could increase diversity of the restored site.
