Restoring peatland plant communities on mineral well pads
|Advisor:||Rochefort, Line; Nadeau, Léonie|
|Abstract:||Peatlands are largely represented in the boreal region of Alberta but little is known about their restoration on well sites. The goal of this study is to compare plant communities and substrates in order to recover peatland vegetation. Two field experiments tested which plant communities (bog, bog-aspen ecotone, willow-sedge fen, shrubby rich fen, treed rich fen) would best regenerate on different substrate (sawdust, clay loam, mix sawdust-clay, peat, surface roughness). We found that peatland communities can establish on mineral soil after propagules transfer using the moss layer transfer technique (MLTT). The choice of plant community, where the propagules are harvested is key to bryophytes establishment. Peat amendment facilitated the plants establishment. The MLTT is a promising approach to restore fen plants on well sites. We recommend a scale-up experiment for a whole well site to test the validity of MLTT within pad removal techniques.|
