Impacts of oil sands process water on fen plants: Implications for plant selection in required reclamation projects
چکیده انگلیسی

Fen plant growth in peat contaminated with groundwater discharges of oil sands process water (OSPW) was assessed in a greenhouse over two growing seasons. Three treatments (non-diluted OSPW, diluted OSPW and rainwater) were tested on five vascular plants and four mosses. All vascular plants tested can grow in salinity and naphthenic acids levels currently produced by oil sands activity in northwestern Canada. No stress sign was observed after both seasons. Because of plant characteristics, Carex species (C. atherodes and C. utriculata) and Triglochin maritima would be more useful for rapidly restoring vegetation and creating a new peat-accumulating system. Groundwater discharge of OSPW proved detrimental to mosses under dry conditions and ensuring adequate water levels would be crucial in fen creation following oil sands exploitation. Campylium stellatum would be the best choice to grow in contaminated areas and Bryum pseudotriquetrum might be interesting as it has spontaneously regenerated in all treatments.


► Fen plant growth was assessed under groundwater discharges of oil sands process water.
► Sedge and grass species were not stressed after two growing seasons in greenhouse.
► Carex species and Triglochin maritima would be helpful in created contaminated fens.
► In dry conditions, contaminated groundwater discharge was detrimental for mosses.
► Campylium stellatum would be the best choice in created fens with contaminated water.
