"This report identifies 83 key terrestrial habitat sites for migratory birds in the Northwest Territories and Nunavut. These sites support at least 1% of the Canadian population of at least one migratory bird species (or, in some cases, subspecies). Sites also include marine and freshwater habitats where the value of the terrestrial habitat is intimately linked to the presence of aquatic habitats. Data for the identification of sites were drawn from existing published and unpublished reports and personal communications. In this updating of key terrestrial habitat sites in the Northwest Territories and Nunavut, eight new sites have been added and two have been removed. Four sites listed in the previous edition have been combined under a single location. Many of the sites recognized in earlier listings have been revised, some quite substantially. Eighteen of the key terrestrial habitat sites overlap with existing Migratory Bird Sanctuaries, and two sites overlap with National Wildlife Areas. This report describes key terrestrial habitat areas that are essential to the welfare of various migratory bird species in Canada. It serves as a statement of the interest of Environment Canada's Canadian Wildlife Service in lands where special wildlife conservation measures may be required, and it is offered as a guide to the conservation efforts of other agencies having interests in the Northwest Territories and Nunavut."--Abstract.
