Bermuda: How shipwrecks can save our dwindling coral reefs 

While global warming and pollution are threatening our coral reefs Bermuda is a rather unusual success story.

Unlike more famous coral reefs like the Australian Barrier Reef which are in decline the coral reef around Bermuda is healthy and expanding.

One reason is that Bermuda is hundreds of miles from the US and other Caribbean islands and has no industry to speak of to pollute the seas.This tiny island has a coral reef far larger than the island itself. The Atlantic Ocean north of the island is in some areas just between three and twelve feet deep.

As a result the area is dotted with shipwrecks. So many ships have ran aground there and many have not been discovered. But here is the interesting point. These shipwrecks are incredibly beneficial to coral reefs. Sunken boats create a structure for corals to grow and are magnets with for fish with plenty of hides holes. And it appears rather surprisingly that the rusting iron of the hulks acts as a fertiliser to help coral establish itself. One of the few cases of human made debris being beneficial.

According to the tour guides who took us there is now growing interest in sinking redundant ships on the edge of coral reefs once they have been decontaminated. They are colonised by the coral which expands the reef.

One example is HMS Vixen a former Royal Navy ship which ran aground a century ago whose hull as the picture shows still sticks out of the shallow water. Here it is a magnet for grey snapper, Chubb and various tropical fish.

Bermuda’s coral reefs are also refuges for turtles which are protected from predators and conservationists have brought back turtle eggs to hatch on the island’s beache to re-establish and expand the population.

Not all Bermuda’s Eco experiments have worked. Just off the coral reef there is an abandoned Eco village. The houses are built on stilts on the coast with canvas rooves and no air conditioning and sound proofing.As a result they are unlettable in the summer when there is high humidity and people’s conversations can be heard from house to house.At the moment the government is desperately trying to flog them off to anybody who might want to use them as a spare summerhouse.

Some facts on tax haven Bermuda which free market Tories might like and Socialists hate. Income tax minimal at just six per cent or nothing for 65000 inhabitants.As a result there is a 17.5 per cent tax on everything that is sold there which is already expensive because it has to be imported. Average house prices are $800000. Cheapest one bed flat $300000. Some affordable houses for $300000 – these are ex Royal Navy homes. Lucky to get a beer for £7 and to eat out for two could cost over £100.

Not much chance of Liam Fox negotiating an independent trade deal – unless he wants to expand its tax haven status with the City. Bermuda doesn’t make anything except rum cakes. So apart from flying them in on direct services between Gatwick and Hamilton don’t expect anything special.

Bermuda until 1960’s had a naval presence. Plans by Gavin Williamson the defence secretary to bring back Royal Navy bases in the Caribbean should make it the ideal centre. A few slight problems.The Royal Navy commissioner ‘s house is a museum, the deep water berths are now cruise ship terminals and the port buildings a shopping mall. Apart from that it should be plain sailing.
