How much are mangroves worth?

How much are mangroves worth?

It’s no secret that we at Lake Worth Waterkeeper are big mangrove fans.

At least twice a month you can find us and our intrepid volunteers tromping around in our mangrove planters at Jewell Cove and Bryant Park, picking up trash, looking for fiddler crabs, and checking on our mangrove nursery. We love mangroves so much because we understand and appreciate what they do for our human and non-human communities, our mental and physical well-being, and even our economy!

In much of south Florida, our economy is tourism based– fishing, diving, boating, and almost perpetually sunny beaches are huge draws to people from all over the world. Businesses of all kinds reap the economic benefits of tourists and snowbirds flocking to our coastal communities – and we have mangrove systems to thank for most of it!

Mangroves are considered a nursery ecosystem, providing food and shelter for hundreds of species of juvenile fish. An estimated 75% of the game fish and 90% of the commercial species in south Florida rely on mangrove systems during at least part of their life cycle.

Florida Fish and Wildlife Conservation Commission (FWC) estimates that saltwater commercial fishing generates $3.2 billion in income, and supports 76,700 jobs. Saltwater recreational fishing brings in around $9.2 billion, and supports 88,501 jobs. Many species of tropical fish also rely on mangroves during their life cycles. In a study published by the National Oceanic and Atmospheric Administration (NOAA) in 2021 looking a reef-related diving and snorkeling, it was estimated that Palm Beach County accounted for the highest economic impact and number of jobs supported by the dive industry. Results from this study show that reef- related diving and snorkeling in Southeast Florida support 8,668 jobs and generate about $902 million in total economic output over the course of a year. We owe a LOT of our tourism dollars and jobs to these mangrove ecosystems!
Mangroves play such a large role in supporting fish, and other marine and estuarine (and even some freshwater) species because they create habitat. Specifically, the red mangrove, or walking tree, with its distinctive aerial root system, plays a unique and essential role in creating productive estuarine habitat. Their roots grow down into the water and create underwater labyrinths perfect for hiding from larger predators. The submerged roots also provide hard substrate for organisms like oysters, barnacles, sponges and other invertebrates. Their leaves drop down into the water and decompose into nutrient rich detritus, feeding a variety of organisms and creating a strong base for many food webs, including those that support those valuable game and commercial fish species!

Mangroves are also allies in the fight against climate change. They are among the most carbon-rich forests in the tropics, sequestering up to four times as much carbon as rainforest per unit area. One estimate puts the carbon sequestration services of Caribbean mangroves at ~$6.6 billion. Continued loss of mangroves would release this dangerous stored carbon into the atmosphere.
The tangled, dense roots and branches of the red mangrove also act as barriers against storm surges and wave action that can cause erosion, property damage, and even loss of life. A scientific study published by the Nature Conservancy, UC Santa Cruz, and RMS found that the presence of mangroves significantly reduced the damages from storms and are a strong first line of defense for coastal communities.
The study concluded that mangroves in Florida prevented $1.5 billion in flood damages and protected over half a million people during Hurricane Irma in 2017, reducing damages by nearly 25% in counties with mangroves. According to the study, mangroves most effectively reduce flood risk where they are abundant and located in front of areas with high densities of people and property. In vulnerable Miami-Dade County, urban coastal mangroves protected high-value coastal properties from over $134 million in potential flood damages from Hurricane Irma. According to an International Union for Conservation of Nature (IUCN) summary, the insurance industry is increasingly interested in the role mangroves can play in protecting property, even leading some to lower premiums in areas where mangroves are shown to reduce property damage from storms and therefore, large insurance pay-outs.

In comparison, the Snook Island restoration project off the Lake Worth Golf Course cost about $18 million, and when Hurricanes Frances and Jeanne hit mid-construction, neither the project, nor the Lake Worth Golf Course shoreline sustained damage.

In areas where those systems have already been lost or degraded, there is a strong economic and ecological case for mangrove restoration. Approximately 70% of the Lake Worth Lagoon shoreline is man-made bulkhead. We have a wonderful opportunity in our communities to invest in living shoreline preservation and restoration. In many cases, protecting and restoring whole mangrove systems has been shown to be less costly than building and maintaining artificial storm protection, and they provide many more ecosystem services, such as habitat creation, than artificial shorelines.

It is clear from the research that natural, intact mangrove systems offer the most value for local communities, governments, and investors.

It is difficult to quantify in dollars the total value of natural places. These estimates still don’t adequately capture the entire value of our mangrove systems, and in reality, they are likely even more valuable than the numbers reflect. While we can put a price on certain parts or functions of an ecosystem, how much is a day spent fishing with your children, or a once in a lifetime encounter with a sawfish truly worth?
These are questions that only we as individuals and communities can answer. The research does make one thing clear: the high value of these intact, healthy ecosystems challenges the generally held assumption that profiting off of nature has to involve extraction. In many cases, and certainly when it comes to mangroves, nature is more valuable to us when it is protected, restored, and allowed to thrive.

“A blue-green algae bloom was identified in water discharging to the Lake Worth Lagoon last month with toxin levels high enough to trigger the posting of multiple warning signs at Spillway Park, a popular fishing spot”

-The Palm Beach Post

Towns all over the Lake Worth Lagoon watershed are being subjected to a toxic cyanobacteria bloom that fills the air with a poisonous stench. Humans breathing cyanotoxins have an increased risk of neurodegenerative diseases like amyotrophic lateral sclerosis (ALS), multiple sclerosis, Parkinson’s disease, Alzheimer’s disease, Huntington’s disease, and prion diseases –and all are incurable. Pets can be mortally sickened. From the Glades to Palm Beach, we should all RAISE OUR VOICE.

If enough of us take action quickly, our Commissioners should attend the Army Corp of Engineers’ LOSOM meeting on Friday from 9am to 3pm and fight effectively for us.

The Cyanobacteria Saga

The Cyanobacteria Saga

There was a notable inspiration behind the forming of Lake Worth Waterkeeper: the lost summer of 2016.

That summer the Lake Okeechobee cyanobacteria bloom made it all the way to the Lake Worth Lagoon, the bloom stopped right at the S-155 Spillway one of my favorite fishing spots.

Then I could confidently claim that there was no vocal advocate devoted to the Lake Worth Lagoon, especially when it came to the ever important Everglades restoration and Lake Okeechobee issues. The other northern estuaries were well covered, but the Lake Worth Lagoon left a void that needed to be filled. That summer I was inspired to take my environmentalism to the next level and to fill that void.

Three years ago during the summer/cyanobacteria season after Lake Worth Waterkeeper’s formation I did this news piece where I pointed out the Lake Okeechobee bloom was blooming again, and that the water was destined to be sent our way soon

At the time, there were limitations on sending Lake O water our way. But those limitations were temporary, and – as I pointed out then – if we’re not attentive to the process we are in danger of taking on even more toxic Lake Okeechobee discharges.

We’re at a pivotal moment with that process right now. The Lake Okeechobee System Operating Manual (LOSOM) is being updated. This policy determines Lake Okeechobee’s management, specifically how its water is moved throughout the Greater Everglades ecosystem. Right now the changes being made are suggesting a move toward more Lake O discharges into the Lake Worth Lagoon.

Since my start as your Lake Worth Waterkeeper I have spent much of my effort in calling attention to the environmental plight of the western half of the lagoon’s watershed, the Glades. The communities here are hurt the most by environmental and public health problems in the state. Yet, little attention was given to this plight. Tragic for the communities affected and detrimental to the Everglades movement as a whole, because solving the environmental problems in the Glades would have very real and long standing effects throughout all of the Greater Everglades. Largely because environmental work here calls attention to the true culprit of most of our environmental problems – Big Sugar.

Recently our work has been gaining so much momentum. Unfortunately this summer is looking like it’ll be a bad one for Lake O. But we certainly appreciate the sudden increase in attention being given to the Glades community and our watershed on this issue. Pahokee Marina is being hit hard right now with the worst part of Lake O’s cyanobacteria bloom so far.

With all eyes on our area – from the media, other environmental groups, and especially other communities in our neighboring northern estuaries – we are looking forward to carrying this momentum forward, because if we work together to help the Glades we certainly will be working for a better Greater Everglades.

Protecting Lake Worth Lagoon from Developers

Protecting Lake Worth Lagoon from Developers

Taking a fight to a state agency head is no easy task,

but this case is bigger than the Lake Worth Lagoon, because it threatens to open up un-permitted development anywhere on Florida’s awe-inspiring coastlines.

To put it briefly, the chairman of the Florida Fish and Wildlife Commission, Mr. Rodney Barreto, is charged with protecting our fisheries and wildlife

—yet he is pursuing condo development on Lake Worth Lagoon that would mean filling or dredging a total of 16 acres.  This would make room for 300+ residences, 2 marinas, etc, beside Singer Island and MacArthur State Park, and wipe out the current habitat sheltering manatees, young green sea turtles, bonefish, small sawtooth fish, manta rays and more. 

When the top boss of a powerful state agency chooses to enrich himself at the expense of the environment and community

–in my honest opinion, it’s a terrible disservice and my main reason for doing this work. To me, this is exactly why Florida has a bad reputation for corruption in government, and the complete disregard for the state’s natural beauty and resources, in favor of money-making.

This may be a lengthy legal battle to stop these and other development plans for our Lagoon, but the animals can’t fight for themselves.

Contributions to Lake Worth Waterkeeper will make a difference to the community of fish, birds, manatees, turtles, residents, tourists, fishing & diving enthusiasts, kayakers, canoers, day trippers and all who love having healthy water and a clean beach.

Top Florida wildlife official wants to fill, build on lagoon

Top Florida wildlife official wants to fill, build on lagoon

Florida’s top appointed protector of wildlife wants to make millions by dredging up and filling in acres of the wildlife-filled Lake Worth Lagoon.

Rodney Barreto, an influential lobbyist who chairs the Florida Fish and Wildlife Conservation Commission, is pressing legal action to let his company fill, dredge and build hundreds of condos and houses on mostly submerged land off Singer Island.

The company, Government Lot 1, LLC, based in Coral Gables, seeks to reopen and expand upon a 1990 circuit court order that gave previous owners the right to fill but not dredge the 19-acre site off Singer Island without requiring permits from state regulators.

Government Lot 1, after buying the site in 2016 for $425,000, proposed three multifamily buildings with 110 units each, 15 single-family lots with two docks each and a 50-slip marina that includes a restaurant and community center on the site. The project called for filling more than 12 submerged acres and dredging another 4, on the northwestern end of the barrier Island, just south of John D. MacArthur Beach State Park.

The South Florida Water Management District in 2018 expressed “serious concerns” about potential impacts on the estuary and determined the plan could not move forward without extensive measures to mitigate environmental damage. The company withdrew its plan but in August 2020 moved to reopen the 31-year-old circuit court case, asserting that its final order should be supplemented to clarify that state regulatory approvals are unnecessary to move ahead with development. The company acknowledges that federal approval, from the U.S. Army Corps of Engineers, still would be required.

Opponents argue that the site should be preserved, that its clear waters and sea grass serve as a nursery and migratory spot for manatees, endangered green sea turtles and smalltooth sawfish and other abundant wildlife.

Lisa Interlandi, executive director of the Everglades Law Center, called the project a blatant conflict of interest for Barreto and one that compromises his agency’s responsibility to protect Florida environmental treasures. Her organization, which litigates for environmental protection, last week moved to intervene in the case on behalf of nonprofit Lake Worth Waterkeeper, to block the project.

“The days of turning water to land and land to water have thankfully passed,” Interlandi said. “We hope.”

Barreto said the project posed no conflict with his FFWCC duties. The state sold and conferred the right to develop the submerged land decades ago, just as much of the lagoon is developed, he said in an email last Wednesday to The Palm Beach Post.

“Although I will not be directly participating in any decision by the FFWCC, I am prepared to take appropriate action in response to any unlawful interference with my property rights,” he wrote. “Furthermore, I will continue to exercise the duties of my position with the FFWCC in a manner that vigorously protects the state’s resources without abusing its governmental authority in a manner that fails to seek a balance that shows due respect for vested private property rights.”

James. D. Ryan, the North Palm Beach lawyer who filed the motion to reopen the case, could not be reached. Ryan’s motion also asserts that other property owners in that area similarly should be allowed to build on their submerged land without state approval.

Barreto agreed, saying nearby landowners Fane Lozman and Daniel Taylor, with whom he has collaborated in the matter, have identical rights and should be allowed to move forward and coordinate development of their properties with his.

“This approach would improve the likelihood that the taxpayers do not become saddled with an enormous financial obligation, the owners develop a portion of the property in a manner that allows their financial expectations to be realized and some of the property being dedicated to conservation.” Government Lot 1’s 2018 plan called for a 1,200-foot long line of mangroves to be planted on his site.

A closer look at Rodney Barreto

Barreto, a lobbyist and one-time Miami policeman, has long been a force in government circles in Miami-Dade County and around the state.

A co-founder of Floridian Partners, a lobbying firm with offices in Tallahassee and Miami, he also presides over The Barreto Group, which specializes in corporate and public affairs consulting, real estate investment and development. He chaired the Super Bowl Host Committee in 2007, 2010 and 2020 and was named to Gov.-elect Ron DeSantis’ Inaugural Committee in 2018.

He was appointed by Gov. Jeb Bush and re-appointed by Gov. Charlie Crist to the Florida Fish and Wildlife Conservation Commission, where he served two five-year terms initially, much of that time as chairman. After his terms expired, he became a member of the Florida Fish and Wildlife Foundation, a citizen fundraising and promotional group that supports the commission. Then Gov. DeSantis reappointed him to the FFWCC in 2019.

Reinaldo Diaz, president of Lake Worth Waterkeeper, an environmental monitoring and advocacy group, looked out Thursday over the expanse of mangrove-lined waters rippling above Barreto’s submerged land.

It’s among the most pristine and abundant sections remaining of the lagoon, he said, the water reflecting in his mirrored sunglasses. “You would think somebody in charge of the FFWCC would know the value of a mangrove habitat.”

Blocking it off with seawalls would destroy a sloping shoreline where horseshoe crabs come to nest and a shallow, sea grass lined stretch where bone fish and “extremely rare” smalltooth sawfish swim, he said. What’s more, a decision allowing development here, as it might have been in the past, ignores decades of environmental learning and could have ramifications for habitats elsewhere in Florida, Diaz said. “We know better now.”

One Singer Island resident whose home overlooks Barreto’s site acknowledged that his own property sits on land a developer filled in the late 1950’s. But he agreed with Diaz that society today has a heightened awareness of the need to protect such waters.

A lot of things have changed over the decades, said the resident, who asked not to be named. “Smoking was good for you in 1960.”

Barreto, though, said he has every right to rely on and profit from almost 100 years of political and legislative decisions that shored up the property rights attached to the submerged land he owns.

“Nearly a century ago the governor and his cabinet, acting as the Trustees of the Internal Improvement Fund (TIFF) for the state, made a determination that it was in the state’s best interests to sell land in and around Lake Worth (Lagoon) for development,” he said. “In accordance with the General Laws of the State, such sales conferred specific rights enumerated in the law, i.e., to dredge, fill and bulkhead the conveyed land unless the deed expressly included an encumbrance restricting such rights….”

The TIFF sold 311 acres at that time, including the land his company eventually bought, and about half of that total has been filled and sea-walled, he said.

“About 50 years ago, when only a few miles of the lake’s shore remained untouched, the state made a decision to preserve some of it and it did so by purchasing the land that is now John D. MacArthur State Park,” he continued. The state decided not to buy any of the Government Lot 1 land and left the private property rights intact, he said.

Subsequent court decisions confirmed those rights and said the owners could develop the site without permission from any state regulatory agency, he said. “I do not believe the state or the FFWCC has any lawful basis to terminate those rights,” he concluded.

Decision in court’s hands

The court must now decide whether those rights hold against the current of decades of environmental research, regulation and legislation. If they do, it will be left to the U.S. Army Corps of Engineers to weigh the project on its merits.

“There would likely be discussions regarding the purpose and need of the project, as “housing” is not considered a water-dependent activity,” Army Corps Public Affairs Specialist Nakeir Nobles said Thursday. The project also would have to pass muster with the Endangered Species Act and compensate for environmental damage, she said.

Interlandi said Barreto should deed the submerged land back to the state, as it’s a stone’s throw from MacArthur Park. He has no right to dredge and the state has a responsibility to enforce laws that protect waterways from harmful development, she said.

“Mr. Baretto did not acquire this land 100 years ago, he purchased it approximately four years ago, He has served on the Fish and Wildlife Conservation Commission for more than 10 years, which is more than enough time to realize that filling in habitat for sea turtles and manatees to build condos and luxury homes would be an extremely bad idea….

“If Mr. Barreto’s approach prevails, what would it mean for commercial and recreational fishing all around the state? How many of these deeds exist in Florida waters and if the state is not able to enforce the law, how much will the public have to pay to protect critical environmental and fishing habitat from development?”

Barreto said he won’t give the property back to the state. If the state wants to conserve it, it can buy him out, he said.

“But we have discussed reaching a compromise that would create permanent protection over some of our land without any expense to the taxpayers,” he said. “This could result in land being added to the park.”

Interlandi dismissed that idea. “In exchange for his being able to develop the land?” she asked. “No way.”

This Thursday and Friday the FFWCC commissioners are scheduled to hold one of their five meetings per year. The Friday session includes a portion for up to three hours of comment from the public on items not on the agenda. Interlandi said she expects members of the public to voice objections to the chairman’s development plans then.
