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.
The study, led by the U.S. Geological Survey, is part of a five-year status review for the endangered marine mammal. The scientists concluded that the long-term probability of the species surviving has increased compared to a 2007 analysis, mainly because of higher aerial survey estimates of population size, improved methods of tracking survival rates, and better estimates of the availability of warm-water refuges.

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.
In some Florida locations, harassment of manatees by visitors may be out of control, according to Public Employees for Environmental Responsibility, which last month said it will go to court to try and end the programs.
An email written last year by outgoing Crystal River National Wildlife Refuge/ Kings Bay Manatee Refuge manager Michael Lusk may be a “smoking gun” that shows exactly how visitors are disturbing the animals. Without adequate resources to manage the swim-with-manatees programs, the activities are likely to contribute to the decline of the species. Continue reading

Watchdog group challenges disciplinary action, says state officials may have violated law by requiring alteration of meeting records

FRISCO — Florida Governor Rick Scott’s hear-no-evil approach to climate change has led to a harsh, and probably unjustified, reprimand for a state worker who discussed global warming and the proposed Keystone XL Pipeline at an official state meeting in late February.
Barton Bibler, the land management plan coordinator in the Florida Division of State Lands, was ordered to take a two-day leave of absence and get a doctor’s clearance before returning to work.
Public Employees for Environmental Responsibility, a watchdog group, has formally asked state officials to investigate the disciplinary action against Bibler, suggesting that his supervisor’s orders to alter records from the meeting may warrant criminal investigation. Continue reading

Critical habitat needed to protect marine mammals
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. Continue reading

‘Smart’ adaptation plans needed to protect critical beach nesting habitat
FRISCO — Florida’s strategy of trying to “harden” beaches to prevent erosion poses a serious threat to sea turtles, university scientists said this week, outlining results of a study that tracked reproduction for 30 years.
Hardening beaches puts up barriers to wildlife and impacts sea turtles’ ability to nest,” the researchers said. Continue reading

FRISCO — Panther deaths in Florida climbed to a record level in 2014, as the wild cats continue to succumb to collisions with vehicles on highways in southwest Florida.
In all, 30 panther deaths were reported by the Florida Fish and Wildlife Conservation Commission this year, topping the previous record of 27 deaths tallied in 2012. More than half of this year’s deaths were the result of collisions with vehicles.
Panther mortality this year could represent as much as one-fourth of the entire population, which the Florida Fish & Wildlife Conservation Commission estimates at between 100 and 180 animals. The reason for this wide variation is that the number of cats monitored through radio collars has steadily declined. Continue reading

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.
The agency this week started taking input on a draft environmental assessment for management actions to protect manatees and still allow public access at Three Sisters Springs during the winter season. Continue reading
