Thaidene Nëné National Park Reserve is a protected area in the vicinity of the east arm of Great Slave Lake, located on the northern edge of the boreal forest of Canada in the North Slave Region of the Northwest Territories. The National Park Reserve consists of a national park administered by Parks Canada and an adjacent protected area administered by the Government of the Northwest Territories. The current land withdrawal covers an area of approximately. The area has been subject to interim land withdrawals by which "no new mining claims or oil and gas rights will be issued for the affected area" while decisions are being made. Some areas of potentially high mineral content have been excluded from the proposals, such that certain industrial and commercial activities will likely be approved to continue in those areas. Designation as a national park would prevent the expansion of uranium and diamond mines into the park's boundaries, and works to protect caribou and pelt animals such as "lynx, wolf, red fox, wolverine, marten, moose and black bear". Other mammals inhabiting this park reserve include Arctic fox, beaver, muskox, grizzly bear and barren-ground caribou. The area features red granite cliffs, as well as "a spectacular array of peninsulas, canyons and waterfalls as the forests give way to northern tundra". Various migratory bird species also stage and nest in the area, including ducks and songbirds.
History
Consideration for the creation a national park in the region was withdrawn in 1970 under the Territorial Lands Act, but in 2001 the Łutsël K'é Dene First Nation re-considered the proposal. Consultations for a feasibility study proceeded from 2002 to 2004, which drew the inclusion of the Métis Nation to the process. By 2005, the Łutselk'e produced a Band Council Resolution "supporting consideration of a national park as part of a broader protection initiative for their traditional territory", in cooperation with other AkaitchoFirst Nations. In 2006, the Łutselk'e DeneFirst Nation and the Minister of Environment and Minister Responsible for Parks Canada signed a Memorandum of Understanding which expanded the land withdrawal area for consideration for the national park by an additional and defined a process for working together on matters pertaining to establishing a national park. Originally expected to be designated in 2009, negotiations have yet to be finalized. By 2014, the government of the Northwest Territories through the Northwest Territories Devolution Act took administrative control of the park study area, and by the following year initiated a "matrix of protected area designations" that included a scaled-down National Park Reserve of in combination with a range of territorial designations, conserving 75 percent of the area. Public consultations on the smaller proposed boundaries finished in 2016. The federal government's 2016 budget named the Thaidene Nëné proposal in its allocation of funds to help the National Park Reserve to realization. On June 10, 2015, Parks Canada and the Northwest Territory Métis Nation negotiators reached an agreement in principle on most elements of an Impact and Benefit Agreement. The agreement is subject to internal review and consultation by both the NWTMN and Parks Canada. The Government of Canada announced its proposed boundary for a national park reserve in the Thaidene Nëné area on July 29, 2015 and launched formal consultations on the boundary. On February 15, 2019, the Łutselk'e Dene First Nation voted to approve the creation of Thaidene Nëné National Park Reserve. On 21 August 2019, an agreement was signed by Parks Canada, the Government of the Northwest Territories, and three First Nations establishing a protected area consisting of a national park administered by Parks Canada, and a area administered by the territorial government that includes a wildlife conservation area.
