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

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

Feds consider changing manatee status from endangered to threatened
FRISCO — Gentle, slow-moving manatees are still facing serious threats from motorboats in Florida waterways and should continue be be listed as endangered, according to conservation advocates.
The U.S. Fish and Wildlife Service is considering down-listing manatees, but the move doesn’t make sense, considering that boat collisions are still the leading cause of death, as detailed in a new report issued by the Center for Biological Diversity.
The conservation group charges that federal and state officials have issued permits for thousands of new docks, boat ramps and piers without considering the cumulative effects on the marine mammals who favor the same near-shore waters used by Florida’s recreational boaters. Continue reading

A manatee comes up for air in Florida’s Crystal River.
CRYSTAL RIVER — Getting a closeup look at marine mammals is always a treat. I believe we have a lot more in common with our ocean-going friends than we realize, and we should be trying to listen to what they have to say. This week, I had a chance to visit the Crystal River in Florida this week to look for manatees. The gentle vegetarians are protected by various federal and state laws, but they are still struggling due to extensive development and other human activities along the Florida coast. One of the best places to catch a glimpse of manatees is at Ellie Schiller Homosassa Springs Wildlife State Park about 45 minutes north of Tampa, Florida. Biologists at the park help rehabilitate manatees that have been injured by boat strikes, and from the park’s manatee observatory, it’s easy to see the deep scars on their backs. We’ve made some progress on protecting these magnificent marine mammals, but there’s more work to be done. Continue reading

USGS research shows isolated population
By Summit Voice
SUMMIT COUNTY — Puerto Rico’s manatees could be threatened by extinction because they are relatively isolated genetically, with no cross-breeding between the Puerto Rico population and those in Florida.
The findings, which come from a study of West Indian manatees by the U.S. Geological Survey and Puerto Rico Manatee Conservation Center, could help resource managers make decisions about how to conserve the endangered marine mammal. Continue reading

Researchers assessed changes as human activity grew in a remote Belize coastal area
By Summit Voice
FRISCO — Results of a long-term manatee study in Belize suggest the gentle marine mammals are a true sentinel species, indicating overall ecosystem health of coastal areas.
The research will help strengthen manatee conservation plans, showing the importance of protecting habitat and migratory paths, and working with local populations as well as tourists to educate them about conservation activities.
“Manatees are the proverbial ‘canaries in the mineshaft,’ as they serve as indicators of their environment and may reflect the overall health of marine ecosystems,” said co-author Alonso Aguirre, executive director of the Smithsonian-Mason School of Conservation. Continue reading

Florida developers just can’t let go of their get-rich-quick schemes
By Bob Berwyn
SUMMIT COUNTY — Florida may still be mired in the worst real estate slump in memory, but that has never stopped starry-eyed speculators in the state from trying to make quick buck by scraping raw land and building ticky-tack subdivisions.
One of the latest schemes would make a mockery of the “Nature Coast” designation for a stretch of coastline extending from Clearwater to Ochlockonee Bay that harbors 19 endangered species.
As if the development weren’t bad enough on it own, there are plans afoot to dredge a massive new channel that would result in almost unprecedented destruction of seagrass in Fillman Bayou, with ongoing impacts from heavy boat traffic after construction. Continue reading
