Edéhzhíe has great ecological and cultural significance to the communities of Fort Providence, Fort Simpson, Behchokǫ̀, Jean Marie River, Whatì and Wrigley.
The Horn Plateau, a prominent landform in Edéhzhíe, contains the source waters of the Willowlake, Horn and Rabbitskin Rivers. Traditional knowledge identifies the Horn Plateau as a place that could be relied upon during times of food scarcity in the Mackenzie Valley. Mills Lake and the lower Horn River areas are important harvesting areas for surrounding communities.
A Land Withdrawal Order exists granting an interim land withdrawal of surface and subsurface rights until June 5, 2019.
The Horn Plateau is a unique ecosystem. The headwater lakes and muskeg on the Plateau feed the Rabbitskin, Willowlake and Horn Rivers and Mills Lake, all of which are important fish and wildlife habitat, and sources of clean water.
The richness and diversity of Edéhzhíe have made this area a central cultural and spiritual gathering place for the Dehcho and Tłįchǫ peoples that figures prominently in Dene legends.
Edéhzhíe hosts numerous cultural sites, trails and harvesting areas, and has traditionally been used for hunting, fishing, trapping and other activities. Mills Lake is a key northern wetland on the Central and Mississippi continental flyways for migratory birds.
