Abstract: In this thesis, I was interested in increasing restored peatland value by characterizing plant diversity along pool margins and by developing restoration techniques for this particular habitat. I first conducted inventories in restored and natural peatlands in order to measure the contribution of pools to plant diversity of the ecosystem. I also established two experiments to test the efficiency of the moss layer transfer technique in regard to pool vegetation. Inventories showed that pools enhance plant species richness in natural peatlands. Around created pools though, species associated with natural pools were still absent and non-bog species present six years after restoration. Two experiments revealed that Cladopodiella fluitans fragments need to be covered with straw to regenerate. Only Sphagnum mosses colonised pool margins with the moss layer transfer technique; introduced vascular plants had a very low mean cover after three years and adapted techniques should be developed to insure their establishment in restored peatlands.
