New protection of Canada's ‘Sea of Glass' bans fishing near the reefs

The last living remains of an ancient European species - the 9,000-year-old fragile glass sponge reefs off the coast of Canada - will now be offered further protection

The new designation bans destructive fishing activity near the reef structures following pressure from the Canadian public and marine scientists around the world

The Canadian government has increased protection for fragile 9,000 year-old glass sponge reefs to prevent their destruction by fishing trawlers.

The ancient reefs, which were discovered off the country's Northwest coast only 30 years ago, are the only large-form, living examples of their type in the world. The reefs reach the height of an 8-storey building in parts and cover 1,000 km2 of ocean floor.  

Fossilized remains of the whole reef system today form giant cliffs that stretch across much of the European mainland from Russia, through Germany, France and all the way to Portugal.

The reefs were discovered in 1987 by a team of Canadian scientists surveying the seafloor in Hecate Strait and Queen Charlotte Sound, off the North coast of British Columbia.

The new designation bans destructive fishing activity near the reef structures following pressure from the Canadian public and marine scientists around the world. Scientists estimate that about 50 per cent of the glass sponge reefs have already been destroyed by bottom trawlers and other heavy fishing gear.

Help us keep the Ecologist platform going

Since 2012, the Ecologist has been owned and published by a small UK-based charity called the Resurgence Trust. We work hard to support the kind of independent journalism and comment that we know Ecologist readers enjoy but we need your help to keep going. We do all this on a very small budget with a very small editorial team and so joining the Trust or making a donation will show us you value our work and support the platform which is currently offered as a free service.
