Changes Planned to Lake Okeechobee Regulation Schedule
The U.S. Army Corps of Engineers is making changes to the 11-year-old federal guidelines
that regulate water levels in Lake Okeechobee without the usual public comment due to the "immediate" need,
according to an internal Corps letter that was circulated among Palm Beach County commissioners last month.
The Corps said that lowering the lake this year beyond recommendations was necessary to help critical aquatic vegetation regrow after years of
too-high water levels,
and to reduce summer discharges to the St. Lucie and Caloosahatchee estuaries that promote the growth of toxic blue-green algae.
U.S. Sugar promptly sued, saying the Corps' "rogue" decisions to lower Lake Okeechobee puts South Florida's ecosystem
and water supply for 6 million people at risk.
Skimmer Attempts to Remove Blue-Green Algae; Salt Water Shown to Release Toxins
The U.S. Army Corps of Engineers tested out a floating skimmer on Lake Okeechobee last month,
hooking it up with hoses to gurgling machines and train car-size filters on land,
to see if it could be used to remove toxic blue-green algae.
The skimmer, similar to what's used to clean up oil spills, sucks up the water,
which is supposed to be scrubbed free of algae and the nutrients it feeds on and then pumped back into the lake.
The spongy chunks of algae would be separated and turned to bio fuel by breaking down the algae cell structure to extract oil.
Oil is stored as a natural energy in the algae.
If successful, the technology could be used in Lake Okeechobee, Lake Erie and other affected lakes around the country.
Lake Washington, just west of Melbourne, is Florida's latest victim of the blue-green algae that has killed off oysters, seagrass, fish and marine life.
Mississippi closed all 21 of its beaches due to a blue-green algae bloom in the Gulf of Mexico last month. Here's everything you wanted to know about blue-green algae, including the short-term and potential long-term threats it poses to human health.
A U.S. Geological Survey laboratory study of two potentially toxic types of freshwater cyanobacteria, or blue-green algae, found that exposure to salty water can damage the cyanobacteria cells' walls, causing them to release their toxins into the water. USGS started the investigation after state water quality samples taken in 2016 showed that cyanobacteria from Lake Okeechobee were probably being transported downstream to the brackish St. Lucie Estuary and the Indian River Lagoon.
And here's some background on how the Everglades, Florida Bay, the Lake, and the St. Lucie and Caloosahatchee Rivers got into the state they're in...
SFWMD Determines Proposed Wells Require More Study
The governing board of the South Florida Water Management District is once again considering the feasibility of
using Aquifer Storage and Recovery wells to pump water 1,000 feet underground and store it until it is needed, but this time they
seem to be listening to environmental concerns, deciding that more study is needed.
The wells would be part of a project intended to hold and clean fertilizer-laden water coming into Lake Okeechobee from the north,
in order to limit the amount of polluted water that flows into the lake and to reduce the need for harmful discharges into
the St. Lucie and Caloosahatchee rivers and estuaries.
Sargassum Seaweed is Here to Stay
Sargassum seaweed has been choking beaches from the Florida Keys to the Treasure Coast in recent years.
It started in the Caribbean and the Gulf of Mexico in 2011 and year after year has gotten more widespread.
While generally not harmful to people, it smells like rotten eggs when it decays and can cause problems for people with asthma or
other respiratory issues.
Some beaches are so thick with it that it has blocked swimmers from entering the water.
In the Keys it has been decaying en masse in canals, causing fish kills.
Sargassum can also be a benefit to the environment, for example, it provides shelter for hatchling sea turtles,
who feed on the tiny crabs and other organisms that live in it.
The seaweed we are seeing on the beaches is just the tip of the world's largest sargassum forest, that Florida researchers have found stretches from the west coast of Africa to the Gulf of Mexico. University of South Florida and Florida Atlantic University scientists found the seaweed's growth spurts occur in years when runoff from the Amazon River includes large amounts of fertilizer and when an upwelling in the eastern Atlantic brings cooler water and nutrients from the bottom of the ocean to the surface. The extent of the seaweed was measured using 19 years of NASA satellite images and detailed in a study published this month in Science magazine.
While it has been speculated that phosphorus in Saharan dust has been playing a major role in fertilizing the Amazon basin, a University of Miami study released last week found that smoke from African fires burning wild or to clear land has more usable phosphorus in it than Saharan dust. The phosphorus in the dust is not easily dissolved, whereas it is highly soluble in the smoke. That phosporus, combined with nitrogen from runoff coming out of rivers like the Amazon and the Mississippi, are the likely culprits in the seaweed's explosive growth.
Legislature Fails to Address Water Quality and Moves to Silence Concerned Citizens
Toxic blooms of blue-green algae, red tide, and brown tide pose serious public health problems from the Indian River
down to Florida Bay, up the west coast and across Florida's lakes and waterways. All are caused or exacerbated by the increased inflow
of nutrients from fertilizers, sewage and manure into our waterways. A number of bills that would have addressed these water quality
problems failed to pass. And yet, at the end of the session, the Legislature passed and the governor signed a bill that effectively
prevents Florida residents from challenging local government on the kind of bad land use decisions that have cumulatively destroyed
so much of Florida's environment. So says former Martin County commissioner Maggy Hurchalla and numerous editorial boards around the state...
Study Blames Everglades Nitrogen for Bleaching Coral Reefs and Killing Florida Bay's Seagrass
A study, published in the journal Marine Biology by Florida Atlantic University marine biologist Brian LaPointe,
concludes that water from the southern Everglades is harming reefs near Looe Key.
LaPointe said water sampling he conducted over 30 years showed that big pulses of water from the Everglades' Shark River
preceded the Keys' mass bleaching events over the years.
He says the river is polluted with nitrogen from farms and urban development, which can harm corals.
He also blames those high levels of nitrogen for triggering die-offs of seagrass in Florida Bay
after droughts such as those in 1987 and 2015.
Other scientists disagree, saying that more widespread sampling shows nitrogen in the Bay only spiking during natural events like tropical storms, cold freezes and hurricanes, and that LaPointe's sampling is from a single reef and from the Everglades near Tamiami Trail, not from where Shark River actually flows into Florida Bay. Most scientists attribute the seagrass die-offs to the droughts that made the Bay become too salty, and claim that the nutrient-starved Everglades remove most of the nitrogen from the water that flows into the Bay.
Florida Bay's seagrass meadows stabilize the muddy bottom and help maintain the clear water that coral reefs need to thrive. They also provide food and habitat for the marine life that lives on reefs. Part of the complexity is understanding the dynamic between nitrogen and phosphorus, the two chemicals at play in the ecosystem. Seagrass thrives on a ratio of high nitrogen and low phosphorus. Reefs, which are disappearing at an alarming rate and now in the midst of an unprecedented disease outbreak, are the opposite.
For more on how dependent the fish and wildlife of Florida Bay are on clean freshwater from the Everglades and on the hopes that are now pinned on the Everglades Agricultural Area reservoir, here's an in-depth story from Hatch Magazine...
As Seas Rise, Roseate Spoonbills Move North and Inland
Changes in habitat and climate are threatening birds all across the country,
but the Roseate Spoonbill is the rare story of successful adaptation.
Spoonbills were nearly wiped out in the U.S. by the feathered hat craze of the late 1800s.
In Florida, the birds have slowly worked their way back from about a dozen nests to an estimated 4,000 Spoonbill pairs today.
As the deterioration of the Everglades cut off the flow of clean water to Florida Bay decades ago, the first Spoonbills started moving north to new territory along Florida's coasts. Then when the rising ocean levels altered the depths they needed for foraging, many of them moved from their coastal nesting areas and set up rookeries inland, exchanging their saltwater habitat for freshwater.
Now Spoonbills can be found as far north as Georgia and South Carolina. But as they move north and inland, they are abandoning their historic breeding grounds in Florida Bay and the coastal Everglades. Still, Florida Audubon's research director Jerry Lorenz holds out hope that the restoration of the Everglades could supply enough clean water one day to restore Florida Bay as a primary breeding ground.
As Seas Rise, Crocodiles Find High Ground at Turkey Point Nuclear Plant
Turkey Point's man-made canals serve as home to several hundred crocodiles,
where a team of specialists working for FPL monitors and protects them from predators and climate change.
Burmese Pythons Not the Only Threat to Everglades Wildlife
Burmese pythons have established breeding populations at least as far south as Key Largo and as far north as our Refuge
in western Palm Beach County.
Mammals make up most of their diet, and they have taken a huge toll on South Florida's rabbits, raccoons, opossums and other animals.
Although the state has now banned ownership of Burmese pythons and several other large constricting snakes,
it's still legal to buy dozens of other non-native snakes, lizards and other animals at reptile shows,
stores and over the internet for live delivery by express mail.
Facing criticism that other species could escape and become established in the wild,
the Florida Fish and Wildlife Conservation Commission countered that they have been proactive in banning ownership of several non-native birds,
mammals and reptiles, including three species of anaconda, before they had a chance to become established in the wild.
And they are looking at the possibility of banning others, such as the Argentine tegu.
Although the tegu has become established in Florida, the state's eradication efforts began earlier than with the python,
so there may be more hope of containing it.
Hunters have killed a record number of Burmese pythons in the Everglades, with about 1,500 pythons caught last year, nearly triple the number in 2016, reflecting a decision by state agencies to start paying hunters. A female Burmese python that stretched more than 16 feet long was caught in the Everglades of western Broward County last month, and her nest of up to 50 eggs was destroyed.
Everglades Visitors Discover Lubber Grasshoppers
If you can remember the first time you saw a lubber grasshopper,
you might have been as freaked out as these French visitors to the Everglades...
Thrips Released to Combat Invasive Brazilian Peppertree
Several local and federal agencies took another step in protecting the Everglades last month by releasing an insect,
known as a thrip, that had been reared to combat the invasive Brazilian peppertree.
First introduced to Florida in the 1800s as an ornamental tree, the Brazilian peppertree is one of the most aggressive,
non-native plants in Florida, impacting more than 700,000 acres statewide, including portions of the Everglades.
The trees create a dense canopy that crowds out native plants and creates poor habitat for native wildlife.
Rare Ghost Orchid Found to Have More Than One Pollinator
Photographers and biologists working at Audubon's Corkscrew Swamp Sanctuary and at Florida Panther National Wildlife Refuge
have discovered moth species other than the giant sphinx moth are able to pollinate the rare Ghost Orchid...
