Site description The Middle Mackenzie River Islands IBA site consists of a 250-kilometre stretch of the Mackenzie River and the associated shoreline between Redstone River and a spot 30 km north of Oscar Creek. The small communities of Norman Wells and Fort Norman lie along this piece of mountain-bordered river. Of the many islands on the river, some are flat and sandy, while others are large and rocky. Shoreline vegetation in places consists of sedges, horsetails and willows, or of pondweed and other emergent plants. The forests of low-lying shorelines are a mix of White Spruce and Balsam Poplar whereas forests on higher terraces and levees are dominated by White Birch. In December, Moose often take up residence on the islands, but in March or April they return to the mainland.
