Sɢ̲aay Taw Siiwaay K’adjuu Heritage Site/Conservancy is located on Moresby Island approximately 5 km from Mitchell Inlet on the western coast of Haida Gwaii and 35 km southwest of the community of Sandspit. It is part of an archipelago-wide system of protected areas that includes Gwaii Haanas National Park Reserve and Haida Heritage Site, several provincial parks and ecological reserves, and ten other heritage site/conservancies. In total, half of the land base of Haida Gwaii is now in protected status. The heritage site/conservancy includes all of Takakia Lake, and three other smaller unnamed lakes and their tributaries. The heritage site/conservancy covers 597 hectares from an elevation of about 500 metres up to 1,000 metres above sea level.
The Sɢ̲aay Taw Siiwaay K’adjuu Heritage Site/Conservancy area has been used since time immemorial by the people of the Haida Nation for cultural, social and spiritual purposes. The freshwater lakes and the surrounding limestone outcrops are one of the most important locations on Haida Gwaii for rare and endemic plants.
