Population expected to double in the next 50 years
Biologists say current conservation efforts for Florida’s manatees should suffice to help the marine mammals survive for at least the next 100 years. If resource managers continue to protect manatees and their habitat, there’s less than a half-percent chance the population would drop below 500 individuals, the level that would threaten long-term survival.
The new study was done by the US Geological Survey and the Florida Fish and Wildlife Research Institute. It found that Florida’s manatee population is likely to gradually double over the next 50 years and then level off. Over time, environmental and habitat changes will probably cause manatees to become less abundant in South Florida and more numerous in North Florida, but the population as a whole will remain high.

Federal biologists say manatees are on the road to recovery and they’re proposed to downlist the species from endangered to threatened under the Endangered Species Act.
When scientists started tracking the gentle marine mammals, the Florida population was estimated at about 1,200. In the last 25 years that population has grown to about 6,300, with 13,000 across the species’ range, including Puerto Rico, Mexico, Central America, South America, and Greater and Lesser Antilles.

With record numbers of manatees wintering in Three Sisters Springs, and substantial increases in the number of people wanting to see the marine mammals in their natural habitat, the rules are needed to limit the potential for “viewing-related disturbance,” according to refuge manager Andrew Gude.
“Three Sisters Springs is among the top three most frequented springs by manatees in the world,” Gude said in a press release. “It is also the only confined-water body in the United States open to the public while wintering manatees are present. Understandably, more manatees in the springs attract more people who wish to experience them up close,” Gude said. Continue reading “Feds to boost protection for Florida manatees”→
Loss of seagrass habitat, red tide events still seen as key threats
FRISCO — A new report on threats to manatees is full of mixed signals, on the one hand downgrading the extinction threat, but on the other, warning that loss of habitat and cold-water mortality events are still huge threats.
Agency efforts to educate visitors sometimes met with verbal abuse, according to federal biologists
FRISCO — Observations by U.S. Fish and Wildlife Service biologists may bolster a watchdog group’s arguments that well-intentioned swim-with-manatee programs are actually pushing the endangered marine mammals closer to the brink of extinction.
FRISCO — Wildlife advocates say they will the sue the U.S. Fish and Wildlife Service for failing to adequately protect Florida’s endangered manatees. The formal notice of the lawsuit filed this week specifically takes aim at commercial tours that bring hundreds of swimmers into small shallow warm-water lagoons to touch otherwise resting manatees.
Florida manatees are one of the most endangered marine mammals in U.S. coastal waters. Despite their large size, they have low levels of body fat and a very slow metabolism, making them extremely vulnerable to cold and unable to survive long in water colder than 68 degrees Fahrenheit. But the rare shallow warm-water springs manatees need in the winter are precisely those targeted by the increasingly popular swim-with tours.

Refuge managers seek to balance protection of marine mammals with demand for public access at Three Sisters Springs
FRISCO — The U.S. Fish and Wildlife Service says a careful management plan at a freshwater spring in Florida can help protect manatees and ensure public access to the popular Three Sisters Springs recreation area.
