STUART, Fla. — More manatees have died already this year than in any other year in Florida's recorded history, primarily from starvation due to the loss of seagrass beds, state officials said.
What You Need To Know
- Many scientists believe loss of seagrass in the Indian River Lagoon is causing starvation
- Overwhelming number of deaths in the the lagoon and surrounding areas, with 312 in Brevard County
- Environmentalists asking that manatees be considered endangered again
The Florida Fish & Wildlife Conservation Commission reported that 841 manatee deaths were recorded between Jan. 1 and July 2, breaking the previous record of 830 that died in 2013 because of an outbreak of toxic red tide.
The TCPalm website reports that more than half the deaths have died in the Indian River Lagoon and its surrounding areas in Volusia, Brevard, Indian River, St. Lucie and Martin counties. The overwhelming majority of deaths have been in Brevard, where 312 manatees have perished.
Some biologists believe water pollution is killing the seagrass beds in the area.
“Unprecedented manatee mortality due to starvation was documented on the Atlantic coast this past winter and spring,” Florida’s Fish and Wildlife Research Institute wrote as it announced the record Friday. “Most deaths occurred during the colder months when manatees migrated to and through the Indian River Lagoon, where the majority of seagrass has died off.”
Efforts to regrow the seagrass beds in the lagoon have been slow-going. Environmentalists say the seagrass is growing in less than 1% of the lagoon.
The Save the Manatee Club stated that people should avoid boating over seagrass beds and shallow areas where manatees might be feeding, and if you see one, keep your boat at least 50 feet away.
The Marine Resources Council wants state monitoring programs for water quality expanded to include toxins like herbicides and pesticides.
Boat strikes are also a major cause of manatee deaths, killing at least 63 this year.
"The human behaviors, polluting, then we've got wastewater, stormwater infrastructure failures," said Dr. Leesa Souto, the executive director of the Marine Resources Council.
The manatee was once classified as endangered by the federal government, but it was reclassified as threatened in 2017. Environmentalists are asking that the animal again be considered endangered.
The federal government says approximately 6,300 manatees live in Florida waters, up from about 1,300 in the early 1990s.
The U.S. Fish and Wildlife Service declared a "Marine Mammal Unusual Mortality Event" back in April, which unlocks a fund to help cover the costs of manatee rescue and investigations into the causes.
