In 1997, HMCS Saskatchewan was sunk off Nanaimo; 448 days later divers recorded 46 taxa, including 9 molluscs and 7 echinoderms

In British Columbia, artificial reefs are transforming the marine landscape, demonstrating swift colonization by diverse marine species within just a few years. By creating stable surfaces from sunken vessels, these reefs foster thriving ecosystems. Research highlights notable variations in species diversity when juxtaposed with natural reefs. While artificial reefs expand available habitat, they do not replicate the exact communities, ultimately aiding in the preservation of strained natural ecosystems.
