Settlement from 1998 oil spill benefits local beaches and far-away habitat What do New Zealand, a leaky oil tanker and the San Mateo
Coast have in common? The answer highlights the interconnectedness of life, particularly seabird species that migrate long distances between their nesting sites and their feeding areas.
Oil washes up on the San Mateo County Coast Chemical sleuthing matched the unique fingerprint of the oil
recovered at sea to the cargo carried by the oil tanker Command - the first time this technique had been used to identify the source of an oil spill.
By the time the US Coast Guard apprehended the ship, it was in Panama, thousands of miles from the spill. Scientists were able to match the particular chemistry of the oil in the ship's hold to that of
the spill, which led to an early settlement. The owners of the Command agreed to pay $5,518,000, of which $3,913,016 was allocated to restore natural resource damages. Habitat restoration funds established Three San Mateo beach areas will benefit from restoration funds. At the But other funds are going further from the source of the oil spill,
to mitigate habitat for migratory seabird species that were injured or killed by the oil spill. The most interesting project is in New Zealand. Protecting the sooty shearwater In the summers, these birds aggregate in large conspicuous flocks
to feed on shoaling fishes that concentrate in productive coastal shelf waters off the San Mateo Coast and beyond. Shearwaters' feeding territory happens to lie within the shipping lanes of oil
tankers, which makes them particularly vulnerable to oil spills. Their numbers off the California coast have declined precipitously, due to a combination of factors, including pollution.
Although we enjoy watching their continuous feeding activity in the summer, in winter they disappear to New Zealand where they breed on islands of the south coast and are known to the Maori as titi.
The Trustees determined that eliminating predators where shearwaters breed at the Big South Cape Islands would have the most impact in restoring shearwater populations. Norway rats
introduced to these islands are the main threat to the breeding colonies of several species of petrels, terns and shearwaters. On Campbell Island, rats had killed virtually every sooty shearwater.
The rat elimination project will bring an impressive partnering of native Maori community representatives, the New Zealand Government, the U.S.-based research group Protecting the fragile web of life The next time you see a teeming flock of shearwaters, think of
the huge distance they have come to their feeding grounds and the many threats facing them on their long journey, and appreciate the difference this unusual restoration project is making in the sooty
shearwater's survival. |
