Strait of Georgia and Howe Sound Glass Sponge Reef Marine Refuge

The Strait of Georgia and Howe Sound Glass Sponge Reef Marine Refuge is a marine refuge in the Strait of Georgia and Howe Sound, off the coast of Vancouver, British Columbia, Gambier Island, and Bowen Island. The marine refuge was established in 2019 and managed by the Department of Fisheries and Oceans Canada. The area was created with the goal of preserving glass sponge reefs.

History
The Strait of Georgia and Howe Sound Glass Sponge Reef was discovered in 2001. Radiocarbon dating has suggested that similar hexactinellid sponge reefs within British Columbia started forming around 7000 BC. == Biodiversity ==
Biodiversity
The reef is primarily built by three species of glass sponges, including the fingered goblet sponge (Heterochone calyx), cloud sponge (Aphrocallistes vastus), and Farrea occa. The reef provides habitat for many marine species including juvenile rockfish, spiny dogfish, spot prawn, Pacific blood star, Sunflower sea star, and California sea cucumber. == References ==
