Center for Biological Diversity v. U.S. Fish & Wildlife Service

Three conservation groups filed a lawsuit asking the federal district court for the District of Columbia to order the U.S. Fish and Wildlife Service to propose a rule to revise the Florida manatee’s critical habitat. The plaintiffs claimed that the FWS’s ongoing failure to respond to their 2008 petition requesting revision of critical habitat (to respond to changes in the meaning of critical habitat over the previous three decades) constituted action unlawfully withheld or unreasonably delayed in violation of the Administrative Procedure Act and that a 2010 finding that revision of critical habitat was warranted but precluded violated the Endangered Species Act. The plaintiffs alleged that Florida manatees and their habitat continued to face “dire and imminent threats, including the loss of warm-water refuges and poor water quality that causes persistent harmful algal blooms and a profound loss of seagrass, a crucial food source, leading to mass starvation.” The plaintiffs alleged these threats were compounded by boat strikes and climate disruption. The complaint’s allegations also included that climate change is expected to cause an increase in the number and severity of cold-water events that that lead to death for manatees.
