Abstract
The postfire recovery sequence during the last 150 to 200 yr, lichen-ground colonization pattern, and soil development in a parabolic-dune system along the east coast of Hudson Bay, northern Quebec, were documented using fifteen contiguous vegetation belts. Differential plant colonization takes place during succession because of a sustained exposure gradient associated with site position in the dune environment. Along the colonization gradient, seven developmental stages were identified, showing distinct vegetation and soil types and particular lichen-ground polygonal patterns. Soil development proceeded successively from bare sands, regosol, and shallow eluviated dystric brunisol.
