Wandering Tires and Robins
Last week I complained about the total lack of anything interesting on the beach during my early morning walks here on Marco Island. The beach must have been offended. The day after posting that column, I found more sand dollars on the beach than I’ve ever seen. I could have easily picked up 50, maybe even 75 perfectly intact dollars. For the next three days I opted to forego the beach walks due to the cold, windy and/or rainy conditions outside. However, I vowed that on Monday I would venture out regardless of weather.
It was a cloudless morning and our outside thermometer read 48 degrees Fahrenheit at 5:45 AM. I opted for a bit more shuteye to let it warm up but at 6:30 AM the temperature had fallen to 47! Sticking to my vow, I put on undershirt, knit shirt, sweatshirt and a jacket I wear when it’s in the 40s at home. With the “breezy” conditions, it was cold! The walk was worth the pain however. The beach was more like the Marco I love, completely different from when I left it last week. Gone was the beach covered with red algae, only a few wisps of the stuff left. And I saw perhaps the largest starfish I had seen in my years on Marco. It was a perfect 9-armed critter that I would estimate at a foot and a half in diameter. There were also a few interesting shells and a couple of small horseshoe crabs.
I also noticed 3 tires on the beach and wondered how they got there – did they wash up from the Gulf or did someone bring them there? When I got back from my walk that morning, an article in the January 19 Naples Daily News may have supplied the answer. The article, by Brian Skoloff, was headlined “Artificial tire reef now an ecological disaster” and was filed from Fort Lauderdale. In the past, I’ve written of various well- intentioned efforts to do good by the environment, only to find that the efforts either failed to accomplish their objectives or ended up harming, not helping the environment. This appears to have been one such effort.
Much has been written about the dying off of coral reefs and of the decline in marine life and habitat. Fairly recently, I read about a ship being sunk somewhere off one of our coasts in the expectation that it would form an artificial reef that would eventually be teeming with fish and other sea creatures. Sunken ships do provide good digs for marine life. Back in 1972, a different approach was tried about a mile off the shores of Fort Lauderdale. The intent was to create what was envisioned as the world’s largest artificial reef. Instead of sinking ships, the idea was to dump tires on the sea bottom. Not only would this help the ecology of the sea but it would also help solve the problem of huge numbers of tires piling up in landfills.
The idea was tried not only here in Florida at Fort Lauderdale but also by other states, including Virginia and my own state of New Jersey. The tire reef idea was enthusiastically endorsed on a global basis. For example, Indonesia and Malaysia engaged in huge tire dumping programs. In the Fort Lauderdale endeavor, tires were tied in bundles with ropes of nylon and steel. All in all, there are millions of tires under the waters around the world. If I interpret the newspaper article correctly, there may be up to 2 million tires in the waters off Fort Lauderdale.
What went wrong? If you sink a battleship, you can count on it staying where you sank it. A tire, on the other hand, is a good bit lighter than a ship. If the ropes or cables binding the tires together break, off go the tires, which is what has happened when storms or strong ocean currents break apart the tire reefs. In 1998, Virginia’s coast got clobbered by Hurricane Bonnie and lots of Virginia’s tires ended up on the beaches of North Carolina. Last year, volunteers for an organization known as the Ocean Conservancy picked up over 11,000 tires from beaches around the world in its annual coastal cleanup.
Perhaps, the beach littering would be worth it if the tire reefs performed as expected. They have not. Instead of promoting coral growth they’ve been killing it by breaking loose and piling up against natural reefs. Because of their lightness and tendency to wander, they don’t stay put long enough for marine life to stick and flourish. It was a bad idea. In Florida, the new governor’s budget includes $2 million to assist in disposing of the Fort Lauderdale tires, which will be used in road projects and for fuel. How do you pick up those tires from the sea bottom? The military plans to use the tires to train its Army and Navy salvage divers at no cost to Florida, according to the article. I expect that we taxpayers will help pay for picking up those tires.
Tires aren’t the only things fouling things up in Florida. In another article in the same Naples paper, Julia Ochoa complains about “feathered carpet bombers” from up north, some of which may have come down here from New Jersey. The complaint is about a “barrage of robin droppings” that Ochoa says has been raining down on Southwest Florida this past week. I found it strange that a bird that we consider in Jersey to be a welcome harbinger of spring should be thought of as a pest down here.
With the bitter cold weather up North this month, you can hardly blame the robins for scooting down to somewhat warmer Florida. Aside from the distaste for robin droppings, there is an ecological concern. The robins like to eat the red berries of an invasive plant that first came to Florida in the 1800s, the Brazilian pepper tree. The birds go for the berries even though, except for a hard coating that’s removed in the bird’s digestive track, the berries pass through untouched. Perhaps the birds enjoy the bit of alcohol in berries as they age on the tree.
With the robins depositing the seeds along with a natural supply of fertilizer, the pepper trees spread quickly. The robins and other seed-spreading birds like to sit on power lines and as a result the peppers flourish along Florida’s roadways. The pepper trees tend to dominate other plant species, having no natural enemies in the insect or plant world. On Sanibel Island an invasive species strike team wages a constant battle against the pepper tree in Sanibel’s Ding Darling National Wildlife Refuge. Anyway, the robin does have another favorite food down here – seeds from the Sabal, or cabbage palm, the state tree of Florida. Floridians certainly can’t complain when our harbinger of spring helps to spread the state tree.
One last beach note. This morning I found the beach to be another completely different beach, loaded with interesting shells and hundreds of conches emerging from the sand. There were also lots of sea urchins, the first I’ve seen this year. The red algae have reappeared most of it concentrated in a huge carpet on the beach in front of the Marriott Hotel. It must be spring break. There was a distressingly large number of beer cans and bottles on the algae carpet. Bud Light in cans and Corona in bottles seemed the favorite choices of the current Marriott clientele.
Finally, a hearty welcome back from Morocco to our peripatetic Editor. After posting this column, I find that he has a brief mention of the tire reef story in last week''s Bar Chat - my apology for not reading it sooner!
