Deepwater Horizon: Conservationists Warn of 'True Catastrophe' for Wildlife
Oil drifting ashore along the Gulf of Mexico coastline will affect key breeding grounds for seabirds as well as fisheries, wildlife bodies say
May 01, 2010
Conservationists monitoring the spread of oil from the Deepwater Horizon rig across the Gulf of Mexico say the situation is at risk of turning into a disaster for the biodiversity in the area. Coastal areas around Louisiana, Mississippi, Alabama and Florida will all potentially be affected by the spill.
Oil that drifts ashore will impact on important breeding grounds for seabirds and many other species, according wildlife experts. Oyster and lobster fisheries could also be badly hit.
"It seems to me yet another man-made environmental tragedy on our hands," said Martin Spray, chief executive of the UK Wildfowl and Wetlands Trust. "The coast of Louisiana has about 40% of the US coastal wetlands so it's a seriously important area. These are incredibly important for their fisheries as well, so there are human livelihoods involved as well."
"The terrible loss of 11 workers may be just the beginning of this tragedy as the oil slick spreads toward sensitive coastal areas vital to birds and marine life and to all the communities that depend on them," said Melanie Driscoll, a conservation director based in Louisiana for the US National Audubon Society (NAS). "For birds, the timing could not be worse - they are breeding, nesting and especially vulnerable in many of the places where the oil could come ashore."
Efforts to stop the oil before it reached shore may not be enough, she said. "We have to hope for the best, but prepare for the worst, including a true catastrophe for birds."
Chris Mann of the Pew Environment Group said: "The Exxon Valdez oil spill provided a mass of scientific data on how oil affects marine life, ecosystems, coastal communities, fisheries and subsistence economies - the effects extend far beyond the inevitable photographs of seabirds, marine mammals and fish covered in oil."
Important bird habitats at risk in the Gulf of Mexico include Chandeleur Islands, Gulf Islands National Seashore in Louisiana and Mississippi and the Active Delta in Louisiana.
The brown pelican, the state bird of Louisiana, nests on islands in the Gulf of Mexico and its breeding season has already started this year. The NAS said many pairs are already incubating eggs. Other species at risk include terns and gulls that nest on the beach, including the Caspian tern, royal tern, laughing gull and the black skimmer. These birds roost on the beaches and also plunge into the water to feed on fish and other marine life. They are therefore at risk from oil on the surface of the water or if it washes ashore.
Similarly, the American oystercatcher, Wilson's plover and snowy plover feed on invertebrates on the beach and could find their sources of food at risk if oil ends up on their sands.
Ocean-dwelling birds such as the magnificent frigatebird could also be affected by oil on the surface of the water that could damage their feathers.
Migratory birds such as plovers and sandpipers are currently on their way from wintering grounds in South America to their breeding grounds near the Arctic. They usually rest and refuel in the Gulf of Mexico on their long journey across the world.
If the oil flows east, it will encounter the seagrass beds that form a key habitat for manatees, among other species.
Carl-Gustaf Lundin, head of the marine programme at the International Union for the Conservation of Nature (IUCN) told the BBC: "If you've got seagrass beds badly contaminated, clearly the manatees could be seriously affected." Less than 2,500 adult manatees remain in the area and are already at risk from climate change and disturbance by boat traffic.
Mann said that the effects of the Exxon Valdez oil spill in Alaska in 1989 can still be found along the beaches in Prince William Sound more than 20 years after the accident. "And research has shown that polyaromatic hydrocarbons - components of crude oil that are highly resistant to weathering - are also highly toxic to marine life."
The accident could also been seen as a warning for those wanting to drill for oil in the Arctic circle, around Alaska. "With decades of experience in drilling in the gulf, and response equipment nearby, the gulf is one of the 'safest' places to drill," said Mann. "If Deepwater Horizon can happen there, it can certainly happen in the Arctic Ocean, where bitter cold, ice, and extreme wind and wave conditions are everyday facts of life and response equipment would be days or even weeks away."
An Urgent Message From Our Co-Founder
Dear Common Dreams reader, It’s been nearly 30 years since I co-founded Common Dreams with my late wife, Lina Newhouser. We had the radical notion that journalism should serve the public good, not corporate profits. It was clear to us from the outset what it would take to build such a project. No paid advertisements. No corporate sponsors. No millionaire publisher telling us what to think or do. Many people said we wouldn't last a year, but we proved those doubters wrong. Together with a tremendous team of journalists and dedicated staff, we built an independent media outlet free from the constraints of profits and corporate control. Our mission has always been simple: To inform. To inspire. To ignite change for the common good. Building Common Dreams was not easy. Our survival was never guaranteed. When you take on the most powerful forces—Wall Street greed, fossil fuel industry destruction, Big Tech lobbyists, and uber-rich oligarchs who have spent billions upon billions rigging the economy and democracy in their favor—the only bulwark you have is supporters who believe in your work. But here’s the urgent message from me today. It's never been this bad out there. And it's never been this hard to keep us going. At the very moment Common Dreams is most needed, the threats we face are intensifying. We need your support now more than ever. We don't accept corporate advertising and never will. We don't have a paywall because we don't think people should be blocked from critical news based on their ability to pay. Everything we do is funded by the donations of readers like you. When everyone does the little they can afford, we are strong. But if that support retreats or dries up, so do we. Will you donate now to make sure Common Dreams not only survives but thrives? —Craig Brown, Co-founder |
