High-altitude coal waste areas are usually difficult to revegetate. However, naturally occurring plant species may be adapted to the extremely harsh substrate of these waste areas. Ten coal waste areas (spoils) of varying ages in the Rocky Mountains in Alberta were analyzed for physical and chemical properties and vegetation composition. Older spoils have a reduced fraction of coarse material, a higher clay content, a greater moisture retention capacity at -1.5 MPa, and higher levels of… CONTINUE READING
