Wales Harbour Conservancy encompasses an area where the Coast Tsimshian have strong cultural interests, including the desire to pursue their traditional activities as they have done for millennia, in a manner that sustains the biological diversity and natural values of the area.

Wales Harbour Conservancy falls within the Pearse Natural Protection Area for Metlakatla First Nation. This classification recognizes the Pearse Island area as being important for its high natural values. Lax Kw’alaams First Nation considers Wales Harbour to part of the Ts’msedasx Special Management Area. The Ts’msedasx Special Management Area has been, and continues to be, important in providing Coast Tsimshian people with food, medicine, raw materials, cultural items, and goods as part of their economy.
The Coast Tsimshian have numerous harvesting sites in the area and the adjacent foreshores and waterways. The conservancy protects traditional harvesting sites thereby sustaining and enhancing traditional use opportunities. To date, no known archaeological sites have been recorded in the conservancy. The lack of identified archaeological sites in Wales Harbour Conservancy is typical for the British Columbia north coast where few detailed archaeological assessments have been completed. Future archeological site inventories may yet identify additional cultural heritage and archaeological resources within the Wales Harbour Conservancy.
Knowledge of the conservancy’s flora and fauna, especially ecosystems, ecological communities and species of conservation concern, is incomplete.
