Lawsuit Launched Challenging Ongoing Flooding of Endangered Cape Sable Seaside Sparrow Habitat and Everglades National Park

VERO BEACH, Fla. - The Center for Biological Diversity and noted scientist, Dr. Stuart Pimm filed a formal notice of intent today to sue the Army Corps of Engineers and U.S. Fish and Wildlife Service over continued flooding of habitat for the endangered Cape Sable seaside sparrow and Everglades National Park. According to the notice, the two agencies have violated the Endangered Species Act through water releases that place the sparrow at serious risk of extinction and in the process, have altered vegetation across a broad swath of the national park. 

“For 20 years the Army Corps of Engineers has been flooding Everglades National Park in the wrong place and at the wrong time, destroying the Cape Sable seaside sparrow and precious park prairies in the process,” said Noah Greenwald, endangered species director with the Center for Biological Diversity. “This can’t be allowed go on any longer.”

Since 1993 the Army Corps of Engineers has been releasing large amounts of water during what should be the dry season through a series of gates, called the “S12s,” and flooding the western portion of Everglades National Park. The area in question once harbored the world’s largest population of Cape Sable seaside sparrows, with more than 3,000 birds, but flooding has decimated the population, and in recent years, there have been fewer than 300 birds in the population.  As the only population west of Shark River Slough, this population provides the species as a whole with a crucial buffer against extinction should a fire or other catastrophe wipe out the other populations, all east of the Slough. In addition to hurting the sparrows, flooding of the park has eliminated a large area of marl prairie, the most diverse plant community in the Everglades. 

“There is no question that the sparrow population west of Shark River Slough is critical to the survival of the Cape Sable seaside sparrow,” said Dr. Stuart Pimm, Doris Duke professor of conservation ecology at Duke University and long-time sparrow researcher. “It’s unconscionable that flooding of Everglades National Park and the sparrow’s habitat has been allowed to go on for so long.”

The Army Corps and Fish and Wildlife Service have long promised that the Central Everglades Restoration Project would solve problems with flooding of the park by directing flows back to the southeast, along their historic path, but when or exactly how this will occur remains largely speculative. Today’s notice seeks to remedy this situation and gain some certainty for the future of both the sparrow and the park. 

“Despite the long list of plans with complicated acronyms, the Cape Sable seaside sparrow is hanging on by a thread,” said Greenwald. “It’s long past time to fix this problem.”

At the Center for Biological Diversity, we believe that the welfare of human beings is deeply linked to nature - to the existence in our world of a vast diversity of wild animals and plants. Because diversity has intrinsic value, and because its loss impoverishes society, we work to secure a future for all species, great and small, hovering on the brink of extinction. We do so through science, law, and creative media, with a focus on protecting the lands, waters, and climate that species need to survive.
