LeBlanc et al 2012: Moss Layer Transfer Technique: From Bog to Fen Restoration


Theme V. Restoration, rehabilitation and after-use of disturbed peatlands


The moss layer transfer technique (MLTT), a relatively simple restoration technique, consists OF transferring mosses and plant fragments collected FROM a donor site to a contoured and rewetted abandoned peatland surface. Several harvested bogs have been successfully restored according to this method in the last 20 years in Canada by the Peatland Ecology Research Group (PERG). However, during the extraction process, some peatlands are harvested to a deeper layer of peat. The residual peat characteristics are therefore similar to minerotrophic conditions. For the first time in North America, a fen restoration project to an ecosystem level was initiated in 2009 by the PERG. That will provide useful information about what concerns have to be taken into consideration when transferring the MTLL to fen restoration projects.
