dc.description.abstract Native plants that naturally establish and thrive in sand (particularly on active dunes) are adapted to dry, nutrient deficient habitats and have evolved a tolerance to burial and exposure. In 1995, Wild Rose Consulting, Inc. and Syncrude Canada initiated a preliminary study to evaluate psammophilous plants (native to the local boreal ecoregion) for establishment and growth on oil sand tailings near Fort McMurray. Alberta. Seeds and roots of Astragalus aboriginum, Carex siccata, Deschampsia mackenzieana, Elymus mollis, Hierochloe odorata, Hudsonia tomentosa, Salix brachycarpa, and Stellaria arenicola were collected from three active dune sites in northern Alberta and Saskatchewan (Grande Prairie, Lesser Slave Lake, and Lake Athabasca). A preliminary survey of mycorrhizal symbionts was undertaken. Germination was tested after seeds were dried and cleaned. Species with adequate germination were tested for growth in tailing sands under controlled conditions. Astragalus aboriginum, Deschampsia mackenzieana, Salix brachycarpa, and Stellaria arenicola grew well in tailing sands in the greenhouse and were placed in field plots in 1996 (transplanted and seeded). Average survival of transplants in field plots was 80% or greater after two months in the first year. Deschampsia mackenzieana and Astragalus aboriginum seedlings were also emerging. Plants were divided into three groups based on their mycorrhizal symbionts: Elymus mollis, Deschampsia mackenzieana, and Hierochloe odorata formed vesicular-arbuscular mychorrizas, Hudsonia tomentosa and Salix brachycarpa were ectomycorrhizal, and Stellaria arenicola and Carex siccata lacked recognizable mycorrhizae. en
