Lessons in establishing plant communities on constructed fens for oil sands mine reclamation
The third-largest proven oil deposit in the world is in Alberta, underlying 142,000 square kilometers of Canada’s boreal covered by forested uplands and peatland basins. The vast deposit is in the form of oil sands that consist of a mixture of sand, water, clay and oil. Where oil sands are near surface, they are excavated in open-pit mines that remove the overburden landscape to extract the resource. Reclamation is a legislative condition for oil sands operators to replace ecosystems that are lost. This involves recontouring the surface to recreate landscape processes and introducing plant species ...
