Then there’s the example of Palm Beach County, mentioned by the Herald-Tribune, which has dredged its way through a passel of island restoration projects in the 20-mile long Lake Worth Lagoon. (Note its name: it’s a “lagoon.” Unlike Sarasota’s natural bay, where salt and fresh water have mixed for thousands of years, the Lagoon at Palm Beach is an artificial bay, still in the teething stage since its creation a mere 150 years ago, when cuts were made to permit entry of ships into what had been a fresh water lake near the ocean. When it rains, fresh water floods the Lagoon from canals that were dug to drain the land. Those flows cause the Lagoon’s salinity to swing erratically—a danger to young sea creatures, in contrast to the more tender care generally provided by Sarasota’s bays.)
One of Palm Beach County’s naturalists was quoted by the Herald-Tribune as, in effect, taking Sarasota to task for being too timid and slow to get with the island restoration dredging program, which he said was “settled science.” But neither he nor the article mentioned two important points: 1) Roberts Bay doesn’t suffer from the major ills targeted by the Palm Beach projects, and 2) Palm Beach County’s signature project, the 79-acre Peanut Island restoration, didn’t at all diminish the beach, boating or recreational use of a a popular island destination. Rather, much of the $13 million spent on Peanut Island was used to expand use of the island’s popular county park by building hundreds of feet of boating docks, a snorkeling pool, 1.25 miles of paved brick walkways—plus a 23-acre storage area used for dredging material. All wonderful, no doubt, but not what’s needed in Roberts Bay and not what’s usually meant by “science.”
Helpfully, Palm Beach County describes the purposes of its projects (not the drawbacks, but at least the goals are published). So let’s take a look at the description by that County’s Department of Environmental Resource Management of the project that most nearly resembles (in size and layout) what some have imagined for Big Edwards, namely, John’s Island.
Where did they get the sand they needed to cover all those acres? It was sliced off the tops of older spoil islands, including the sprawling Peanut Island, and the smaller John’s Island and others. When they sliced, they also removed “exotic vegetation” from the amputated islands. Costs of the Snook Area project: about $18 million, or roughly $180,000 per acre. Afterwards, says Palm Beach County, seagrass did begin to settle in, and fishermen caught more snook. These Palm Beach projects are popular ones, and perhaps they are exactly what’s required to grow seagrass, mangroves and snook habitat in that area’s artificial bay.
But Sarasota is much luckier. Roberts Bay is already a paradise for snook —no need to first build a “Snook Islands Natural Area.” Seagrass plants itself naturally on the bottoms of Sarasota’s natural bays (if currents aren’t diverted by “restoration” projects and if the water’s not clouded)—no need to strip sand from islands to manufacture “natural” bay bottoms. Muck and “dead zones” are not issues in Roberts Bay. In the narrow Lake Worth Lagoon, they dump boulders to protect new mangroves (as at the Snook Area and John’s Island). But in the sheltered tidal coves and channels on Big Edwards Island, nature’s mangroves are already flourishing--no hand-planting and no boulder breakwaters required.
