U.S. agency to consider endangered species protections for emperor penguin
By WiG reports

The U.S. Fish and Wildlife Service today (Jan. 22) said the emperor penguin may warrant protection under the Endangered Species Act. The most ice-dependent of all penguin species, emperor penguins are threatened by the loss of their sea-ice habitat and declining food availability off Antarctica, according to a statement from the nonprofit Center for Biological Diversity.

"Our carbon pollution is melting the sea-ice habitat emperor penguins need to survive," said Shaye Wolf, climate science director at the center. "Emperor penguins are the icons of wild Antarctica, and they need rapid cuts in carbon pollution and Endangered Species Act protections if they’re going to have a future."

Emperor penguins rely on sea ice for raising their chicks and foraging. In parts of Antarctica where sea ice is rapidly disappearing, emperor penguin populations are declining or have been lost entirely. The emperor penguin colony featured in the film March of the Penguins has declined by more than 50 percent, and the Dion Island colony in the Antarctic Peninsula has disappeared. One recent study projected that nearly half of the world’s emperor penguins may disappear by mid-century without drastic cuts in carbon pollution.

Warming ocean temperatures and melting sea ice in the Southern Ocean encircling Antarctica have also diminished the availability of krill — a key food source for emperor penguins. Ocean acidification resulting from the ocean’s absorption of carbon dioxide and industrial krill fisheries further threaten the penguins’ food supply.

In 2006, the center petitioned the U.S. government to list 12 penguin species, including the emperor penguin, as threatened or endangered. Fish and Wildlife protected seven penguin species but denied protection to the emperor penguin.

In 2011, the center again petitioned for protections for the emperor based on new scientific information demonstrating the species is imperiled. In today’s finding, Fish and Wildlife agreed to conduct a full review to determine if the emperor penguin should be protected under the Endangered Species Act.

Listing of the emperor penguin would offer greater protections against the greenhouse gas emissions driving climate change and the industrial overfishing of key prey species, according to the center. For example, if penguins are listed, future approval of fishing permits for U.S.-flagged vessels operating on the high seas would require minimization of impacts on penguins. The act also compels federal agencies to ensure that their actions — including those generating large volumes of carbon pollution — do not jeopardize endangered species and their habitat.
