Each of the four First Nations has their own distinct tradition, including their unique and thriving dialects. Some of the teachings and skills have been lost or weakened and are being re-learned. The extensive recording of oral history and its codifying into educational programmes and tourist interpretation is an important cultural process, and care needs to be exercised to protect the use of this knowledge. The ability of the First Nations to sustain their culture is also under some threat from socioeconomic and health issues and by acculturation. The former include extremely high unemployment, and health problems (ICOMOS, 2018).
