Everglades Restoration Project Ongoing for 20-Plus Years Sees Huge Rewilding Success
A huge area of the Everglades that was drained in an attempt to convert it to suburbia has been restored to a somewhat native ecosystem after 2 decades of reverse-landscape engineering.
Picayune Strand is a large, almost perfect rectangle of South Florida wetland, located northwest of Everglades National Park and northeast of Thousand Islands Nat. Wildlife Refuge, and west of the Florida Panther Nat. Wildlife Refuge.
It was part of an enormous land package bought by the real estate company Gulf American in the 1950s in an attempt to create America’s largest suburban housing development, called Golden Gate Estates.
But their effort to tame the swamp failed, even though substantial landscape alterations were made to try to dry out the area. Picayune Strand is 2 feet lower in elevation than the Golden Gate Estate land to the north, and this little difference made it virtually impossible to prevent flooding. The company went bankrupt.
One of the first projects identified and pursued by conservationists under the Everglades Restoration Plan of 2000, Picayune Strand has changed significantly over the years. Since 1985, conservationists have been buying up all the private, often unbuilt-on land that Gulf American had managed to sell. It was tedious lawyer’s work, but by 2004, it was all consolidated into a conservation package.
Gulf American built 4 large canals to channel water off the land they wanted to develop, while the earth and stone they churned up were used to crisscross the area with causeways, atop which roads ran. These were the first targets for groups like the Everglades Foundation, the Conservancy of Southwest Florida, and the US Army Corps of Engineers.
The hydrology of the Everglades is defined by water flowing across the once-7 million square miles all in the same direction at roughly the same snail’s pace, a phenomenon described as “sheet flow” through a “river of grass.” Huge areas remained flooded all year, and plugging the canals was the first step towards restoring the natural hydrology.
To restore this, the roads were torn up, and the materials were chucked back into the canals from whence they came.
From macro to micro
“Picayune is as good a place in South Florida as there is, in terms of getting it back to what it was before,” Michael Duever, an ecologist who has been monitoring the Picayune project, told Yale News. “We’re feeling that we’re in the range of 90 plus-or-minus percent of restoration.”
There had to be some compromises, as people still live in Picayune Strand. Part of that 10% is missing; Duever refers to it as 3 pumping stations that pull rainwater out of the closed canals on the northern boundary of the Picayune project and dump it into large basins that will leak it out in many directions. The water level at times is higher than natural, however, and at other times drier.
Vegetation is coming back in a big way—not always ideally, but upland plants cannot now spread further south because of the continual water bodies. More native species that have missed the continual wetness are also returning—like a native, wild sunflower.
The restored Picayune is expected to help several endangered species, including the red-cockaded woodpecker and the Florida panther, while studies have already shown that increased insect abundance is benefiting the bonneted bat, the largest of its kind in Florida, with a wingspan greater than a foot.
“I kind of view Picayune Strand as a microcosm of the entire [Everglades] plan,” Stephen Davis, chief science officer at the Everglades Foundation, told Richard Mertens at Yale.
The good news in this story is that once a mistake is realized, many hands helped make it right again. Today’s JohnKu talks about rectifying mistakes. I hope you have a terrific weekend.

That threatens wildlife and Earth. . .
