Florida’s manatees face starvation

Fewer deaths have been recorded so far this year, but wildlife officials warn of an ongoing threat.


ST. PETERSBURG, Fla. — Fewer manatee deaths have been recorded this year in Florida than in recordsett­ing 2021, but wildlife officials caution that chronic starvation remains a dire threat to the marine mammals.

Between Jan. 1 and July 15, about 631 manatee deaths were confirmed by the Florida Fish and Wildlife Conservati­on Commission. That compares with 864 during the same period last year, when a record number of manatees died mainly from a lack of seagrass, a primary food source that has been decimated by water pollution.

The five-year average of manatee deaths in that time frame is 481.

Despite glimmers of hope, wildlife officials said during a news conference last week that manatees continue to face dwindling food options, and many have been severely weakened by malnutriti­on, which leaves them more vulnerable once cold weather sets in.

How manatees fare this summer when more food is available will determine how they survive in winter, said Martine de Wit, a veterinari­an overseeing necropsies and coordinati­ng rescues of ill manatees for the state wildlife commission.

“There is not enough high-quality food for the animals,” De Wit said, showing slides of necropsied manatees with severe internal damage from starvation. “It’s going to be long-lasting. It’s going to be years before you can measure the real effect.”

Manatees, the roundtaile­d mammals also known as sea cows, were already listed as a threatened species when the unpreceden­ted die-off became apparent about a year ago. The main cause is pollution from agricultur­e, septic tanks, urban runoff and other sources that is killing the coastal seagrass on which the animals rely.

That led to an experiment­al feeding program last year in which more than 202,000 pounds of lettuce, funded mainly by donations, was fed to manatees that traditiona­lly gather during winter in the warm waters near a power plant on Florida’s east coast. Officials say they are still studying the impact of that feeding program and weighing whether to reprise it this winter.

“Did it have an effect? I’d like to think that it did,” said Tom Reinert, a regional director for the wildlife commission. “We’re working day in and day out to make sure we’re prepared for next winter.”

There are about 7,500 manatees in the wild in Florida, according to wildlife commission figures, and they have long struggled to coexist with humans. Seagrass-killing pollution and boat strikes are the main threats facing the beloved creatures.

The U.S. Fish and Wildlife Service recently agreed in a court settlement to publish a proposed manatee critical habitat revision by September 2024.

The agreement came in a long-running court case involving the Center for Biological Diversity, Defenders of Wildlife and the Save the Manatee Club.

The rule would bring enhanced federal scrutiny to projects that might affect waterways in which manatees are known to concentrat­e, such as the Indian River Lagoon on Florida’s east coast. In addition, the state is spending $8.5 million on a variety of manatee projects, such as restoratio­n of seagrass and improvemen­ts in water quality.
