In the 1960s only a few hundred manatee swam in Florida causing the species to be labeled as endangered.
Back in 2007 the US Fish and Wildlife Service recommended moving the manatee from endangered to threatened as the abundance surged to 3,300.
The current abundance of the species in Florida alone is at about 3,300 animals.
Therefore, we believe the West Indian manatee no longer meets the definition of an endangered species . . . we believe the West Indian manatee should be classified as threatened.
Eight years later nothing has been done. Two groups- Save Crystal River and the Pacific Legal Foundation- filed a petition to have the manatee reclassified.
Last summer, the U.S. Fish & Wildlife Service announced it would undertake a year-long review of the manatee’s status to see if it should be reclassified from endangered to threatened. The review was prompted by a petition filed in 2012 by the boating group “Save Crystal River” and the Pacific Legal Foundation arguing that the population is recovering. When the species was listed in 1967, only a few hundred of the creatures swam around Florida’s coastal and inland waters. Today, the population is estimated at over 4,800. Manatee deaths spiked to a record 829 in 2013, blamed mostly on red tide in the Gulf and a toxic algae bloom in east-central Florida’s Indian River Lagoon. But mortality dropped dramatically to 371 last year.
