Maybelle River Wildland Provincial Park, a newly established park located in northeastern Alberta, encompasses some 15,309 hec. The Athabasca Sand Dunes Ecological Reserve is located within the park boundary. The landscape within the park reflects the activity of windblown sand, in the past and present, and fire. This vegetation study was one component of a multi-disciplinary project, which was conducted to develop a preliminary inventory of the natural components of the area. The objective of this vegetation study was to characterize the modal or more commonly occurring vegetation communities and the particular site conditions with which they are associated. The area of the Athabasca Sand Dunes Ecological Reserve has been studied quite extensively in the past (Raup and Argus 1982; Landals 1978); however, relatively little research has been conducted in the surrounding park area.
