PROGRAM AIMS TO SAVE STARVING MANATEES

An unprecedented, experimental attempt to feed manatees facing starvation in Florida has started slowly, but wildlife officials have expressed optimism that it will work as cold weather drives the marine mammals toward warmer waters.

Water pollution from agricultural, urban, and other sources has triggered algae blooms that have decimated seagrass beds on which manatees depend, leading to a record 1,101 manatee deaths, largely from starvation, in 2021. The typical five-year average is about 625 deaths.

That brought about the establishment of a feeding station along the state’s east coast designed to entice wild manatees with romaine lettuce.

The lettuce feeding program, part of a joint manatee death response group led by the Florida Fish and Wildlife Conservation Commission and the US Fish and Wildlife Service, had yet to entice wild manatees, though the animals will eat it in captivity, officials said.

“We have not documented animals foraging on the lettuce,” said Ron Mezich, chief of the joint effort’s provisioning branch. “(But) we know manatees will eat lettuce.”

During winter months, hundreds of manatees tend to congregate in warmer waters from natural springs and power plant discharges. Because this winter has been unusually mild in Florida so far, the animals have been more dispersed.

“They’re moving, but they are not being pressed by cold temperatures yet,” said Tom Reinert, south regional director for the FWC. “We expect that to happen.”

In addition to the feeding experiment, officials are working with a number of facilities to rehabilitate distressed manatees that are found alive. These include Florida zoos, the SeaWorld theme park, and marine aquariums. There were 159 rescued manatees in 2021, some of which require lengthy care and some that have been returned to the wild, officials said.

“Our facilities are at or near capacity,” said Andy Garrett, chief of rescue and recovery. “These animals need long-term care. It’s been a huge amount of work to date.”

There are a minimum of 7,520 manatees in Florida waters currently, according to state statistics. The slow-moving, round-tailed mammals have rebounded enough to list them as a threatened species rather than endangered, although a push is on to restore the endangered tag given the starvation deaths.

Officials are also using US $8 million in state money on several projects aimed at restoring manatee habitat and planting new seagrass beds, but that is a slow process and won’t ultimately solve the problem until the polluted waters are improved.

People can report any manatee they see that might be distressed by calling a wildlife hotline at 888-404-FWCC (3922). Other ways to help are donating money through a state-sponsored fund or purchasing a Save the Manatee vehicle license plate. It remains a violation of state and federal law for people to feed manatees on their own.

Officials say feeding manatees personally does more harm than good because the animals will associate humans with food. People and manatees have struggled to coexist for decades.

“This is a very serious situation,” Reinert said. “Use your dollars and not heads of lettuce.”
