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

Study seeks abrupt climate change clues
FRISCO — Icebergs may have been drifting off the coast of Florida as recently as 21,000 years ago, university researchers said after developing a climate model that recreates ocean currents from the end of the last ice age.
The study implies that the mechanisms of abrupt climate change are more complex than previously thought, according University of Massachusetts Amherst oceanographer Alan Condron. The models are supported by the discovery of iceberg scour marks on the sea floor along the entire continental shelf. 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

FRISCO — Conservation of coastal rivers of the northern Gulf of Mexico is vital to the survival of the alligator snapping turtle, including two recently discovered species, University of Florida scientists concluded in a recent study that sheds more light on the taxonomy of the dinosaurs of the turtle world.
The study shows the alligator snapping turtle, the largest freshwater turtle in the Western Hemisphere and previously believed to be one species, is actually three separate species. Continue reading

Higher summer spikes could mean more destructive storm surges

FRISCO — Annual sea level fluctuations have been intensifying along parts of the Gulf Coast, raising concerns about more hurricane flooding and impacts to delicate coastal ecosystems in the region.
There have always been seasonal fluctuations in sea level, which rise in summer and fall in winter. But a new study shows that, from the Florida Keys to southern Alabama, those cycles have amplified in the past 20 years.
The additional summer sea level rise during the past two decades means storm surges can rise higher than previously thought, according to Thomas Wahl, a postdoctoral researcher from the University of Siegen in Germany who is working at the University of South Florida in St. Petersburg and lead author of the study.

State’s wildlife is squeezed from all sides
Oceanic birds and birds that rely on coastal habitat face challenges related to climate change, according to the 2011 State of the Birds report. bberwyn photo.

FRISCO — The rapid growth of Florida’s population, combined with laissez-faire development policies and the lack of strong environmental regulations is putting the state’s natural resources at risk, conservation advocates said in a year-end press release.
The warning came as the U.S. Census Bureau released figures showing that Florida will soon overtake New York as the third-most populous state in the country, and as Florida’s wildlife continues to struggle in the face habitat loss, urban sprawl, water withdrawals and other effects of rapid human population growth in recent decades.
“As Florida’s human population growth breaks new records, incredible species like panthers and manatees are dying at record rates,” said Stephanie Feldstein, the Center for Biological Diversity’s population and sustainability director. “Florida is a beautiful, biodiversity-rich state, but it has a long history of replacing that beauty with condos and strip malls. If Florida doesn’t get its growth under control, development and concrete are all that will be left.” Continue reading

Listing decision part of far-reaching settlement for imperiled species
By Summit Voice
FRISCO — Chugging ahead on its commitment to make endangered species listing decisions for more than 750 species, the U.S. Fish and Wildlife Service last week announced that three native Florida plants — all threatened by sea level rise — deserved protected status.
Most populations of the plants — aboriginal prickly apple, Florida semaphore cactus and Cape Sable thoroughwort are at, or just above, mean sea level.
“These native plants are being squeezed out of existence — pressed between coastal development and rising sea levels,” said Florida-based Center for Biological Diversity attorney Jaclyn Lopez. “Protection under the Endangered Species Act will give them a role in South Florida’s planning for rising seas.” Continue reading
