	abstract = {Carex aquatilis could be a suitable species for wetland reclamation in mined boreal landscapes as those of the oil sands industry (Northern Alberta). We compared the performance of C. aquatilis plants established in oil sands industrial wetlands (directly affected by processed materials), on-site indirectly affected wetlands, and off-site natural wetlands. We studied leaf chemistry, fluorescence, gas exchange rates (net photosynthesis and transpiration rates), and morphological features of plants. Despite higher photochemistry efficiency in oil sands populations, plants did not channelize surplus energy into increased carbon assimilation rates. Oil sands populations registered lower culm heights and leaf lengths than natural populations. Plants growing in industrial wetlands were shorter and accumulated more sodium in leaves than plants from indirectly affected wetlands. Evidence indicated that C. aquatilis was a promising species for reclamation as it was tolerant to pollution. Though it survived, C. aquatilis, showed a restricted growth in the oil sands wetlands thereby possibly limiting carbon assimilation at the stand level. Oil sands wetlands amended with freshwater and established over non-industrial materials provided better growing conditions for C. aquatilis and demonstrated management tools for local reclamation efforts.
