The Peatland Ecology Research Group (PERG) has developed the Moss Layer Transfer Technique (MLTT) for restoring Sphagnum peatland ecosystems after peat extraction. After thirty years of research, perfecting of the MLTT restoration method has proved to reestablish the carbon sink function of the restored sites, generally within ~15 years. However, unaddressed fragmentation within the MLTT-restored continues to prevent appropriate water distribution over the entire vast areas targeted for ecological restoration. The continued erosion and rapid drainage due to abrupt topographic changes induce the loss of dissolved organic carbon in runoff water, favoring opportunistic plants not typical of peatlands. In addition to fragmentation between sites, discontinuities with the surrounding landscape hinders wildlife movements and have disturbing effects on large-scale ecohydrological conditions. In response, regime changes (from Sphagnum-dominated to tree-dominated communities) are observed. Beyond individual MLTT-restored patches of Sphagnum habitat, this research focuses on developing restoration approaches that will sustainably restore physical connections as well as ecohydrological functions among and within peatland complexes. The field experiments, which include reprofiling and revegetation of large areas will be presented. The importance of considering connectivity issues in restoration projects will be highlighted. More specifically, interventions will be suggested towards restoring ecohydrological functions more typical of peatlands, supported by preliminary findings on groundwater dynamics from a before-after control-impact design. This research is conducted at University Laval, under the supervision of Professors Line Rochefort and Sylvain Jutras, in affiliation with the Centre for Northern Studies (CEN) and the Centre for Forest Research (CEF).
