One of the Sable Islands is an elongated nearshore barrier sandbar, featuring marshes and rounded (“hummocky”) sand dunes. The mainland section of this reserve features peat bogs. Like other areas in the extreme western part of the province, the reserve supports a rich variety of plant life that includes rare species with strong prairie affinities. The mixed boreal forest on the mainland contains white cedar, balsam fir, black ash, white birch, poplar, and black spruce. Shrubs, blue-joint grass, and cattails also grow here. The reserve is undeveloped and unspoiled.
