Biophysical and Ecological Overview of the ƛušiiʔaaʔaq (Swiftsure Bank) Area

Le résumé fourni par la source

The ƛ̓ ušiiʔaaʔaq/Swiftsure Bank Area is located off the southwest coast of Vancouver Island, British Columbia. First Nations have had a relationship with ƛ̓ ušiiʔaaʔaq for millennia, including Ditidaht First Nation, Pacheedaht First Nation, Huu-ay-aht First Nations and the other four First Nations of the Maa-nulth Treaty Society, as well as the Makah Tribe. ƛ̓ ušiiʔaaʔaq is a dynamic marine region characterized by complex interactions between oceanographic, geological, and ecological processes. The area is influenced by the convergence of the North American and Juan de Fuca tectonic plates, resulting in a diverse range of geomorphologies. The Juan de Fuca Eddy, a prominent oceanographic feature, enhances biological productivity by concentrating nutrients and supporting a rich assemblage of marine species. This area also encompasses estuaries and an anoxic fjord (Nitinaht Lake), which provide crucial habitat for numerous fish, invertebrate, and bird species, contributing to the ecological significance of the region. ƛ̓ ušiiʔaaʔaq provides important habitat to a variety of species and is designated as critical habitat for Southern Resident Killer Whales (SRKW) and overlaps Ecologically and Biologically Significant Areas. It is an area of high productivity and supports a wide array of human uses. Recognizing the ecological, cultural, and economic importance of this area, various conservation and management measures have been implemented, including Rockfish Conservation Areas, Pacific Rim National Park Reserve, and protection zones for SRKW. First Nations’ relationships with the marine environment have been, and continue to be, key to the stewardship of ƛ̓ ušiiʔaaʔaq, which provides important resources and is part of the local governance, trading and sharing economies, culture, and the retention of Indigenous language. This biophysical and ecological overview provides a comprehensive summary of the current state of knowledge for the area regarding its oceanography, ecological uniqueness and importance, taxonomic diversity, human activities, and sensitivity to climate change and highlights opportunities for collaborative research to address knowledge gaps.
