The conservancy is within the traditional territory of the Gwa’sala-‘Nakwaxda’xw First Nation.
The Mahpahkum-Ahkwuna/Deserters-Walker islands continue to be an area of high importance to First Nations with a number of cultural sites located on the islands and islets within the conservancy. Two small ‘Nakwaxda’xw village sites were once located in areas that are now part of the conservancy. These village sites, and the waters around these islands, were, and continue to be extremely important for seasonal marine harvesting activities.
The conservancy’s islands are biologically diverse with nutrient-rich waters that provide an intense feeding area for marine mammals, seabirds, shorebirds and waterfowl. The waters surrounding the islands act as a migratory corridor for several runs of Pacific salmon.
