Hernando County: a leader in artificial reef development

 March 16, 2018 – 01:17

Since 1990 Hernando County has been active in artificial reef development. Funding is provided by a combination of federal, state and local government, as well as private funds. This is done through the Division of Marine Fisheries Management of the Florida Fish and Wildlife Conservation Commission (FWC). The FWC assists in developing these reefs, enhancing existing reefs that are already successful and to monitor and assess artificial reefs. According to Frank Santo, chairman of the Hernando County Port Authority, there has been a a large grassroots effort by Hernando County which has had a huge impact on Hernando County’s marine system. These state and federal programs are driven by the recognition of benefits for commercial fishing and tourism. Commercially important fish and sports species are frequently attracted to the artificial reefs for the food source and shelter they provide. As larger fish species migrate through the area in the spring and fall the artificial reefs provide shelter, food and resting areas for such fish as albacore, king fish, Spanish mackerel and cobia. Artificial reefs remain very popular with the fishing public and contribute significantly to local economies.

There are numerous considerations for artificial reef placement. Some individuals may be concerned that artificial reef structures may dislodge and be a detriment to the shore. According to research by Ryan Fikes Staff Scientist, with the Gulf Restoration Campaign National Wildlife Federation in an article in November 2013 titled Artificial Reefs of the Gulf of Mexico: A Review of Gulf State Programs & Key Considerations, artificial reefs need to be placed in clear shallow water with good light. “Water depth at the reef site may critically affect reef material stability and long-term structural integrity” when considering wave conditions. “The reef materials and designs should be properly matched to water depth and predicted wave conditions to ensure their stability. Planning for worst-case storms may need to be considered on sites where movement of materials would be detrimental or hazardous”. The reef material design needs to be matched to the water depth and predicted wave condition to resist breakup, movement or burial. Detailed engineering is important for the success of an artificial reef.

There are few natural reefs in Hernando County and they tend to be over-fished. So artificial reefs allow distribution, growth, and protection of marine life. This relieves the pressure on the natural reefs. Due to the importance of site placement, careful planning and permitting is required as artificial reefs need to be placed near seagrass beds but have to be at least 150 feet away. Hernando County has a rich seagrass bed of 190,000 acres. The bottom is flat and sandy with seagrass interspersed between hard bottom areas. Hernando County seafloor has no structure only flat with occasional holes. Naturally occurring reefs develop over hard, rocky bottoms. Areas between natural reefs are often loose sand that supports marine grasses, such as eelgrass or turtle grass. The seagrass beds support many species and are important in the ecology of adjacent reef systems, providing foraging and breeding sites for reef fish. They provide food, habitat, and nursery areas for numerous vertebrate and invertebrate species. They are the ideal environment for juvenile and small adult fish for escape from larger predators. Many small organisms live in the soft sea bottom like crabs, clams, and starfish for protection from currents. Initial monitoring of new artificial reefs which are placed near seagrass indicate after testing of the first week, there are already juvenile grouper living on the reef.

Much research has been completed internationally in regards to the benefits of artificial reef development. Researchers Gary M. Serviss and Steven Sauers, who were the principal investigators in a detailed research article published in 2003, Sarasota Bay Juvenile Fisheries Habitat Assessment, proved positive impact of these reefs. Although they found the natural reef sites had a higher density of resident and transient species, the artificial sites had a slightly higher mean density of nursery fish. Monitoring indicated that the habitats are doing fairly well when compared to that of the natural habitat types. Their research found that many of the reef-dependent species such as tomtate, gray snapper, and gag grouper were observed and this also held true for the commercially important stone crab. The researchers also found that the diversity of the species tended to increase with the complexity of the material. More crevices provided more safety from predators. Also, the older the artificial reef the higher the diversity of adult fish and fewer juveniles. They found the less uneven surfaces like “concrete block, generally did not provide the number of protected spaces needed for some of the species to successfully habitate. This material type generally had low numbers and low species diversity. However, increasing the complexity of a concrete block pile with the presence of reef balls greatly improved the diversity and numbers of fish species present.” This resulted in a wide variety of different species with four size classes, from the early juvenile stage of some up to the largest adult stages.

Mr. Santo stated that initially there was not much interest in the community for these projects, but now our county administrators have realized these artificial reefs have increased tourism and have had a sound environmental impact. As a result, Hernando County is getting respect among fisherman and the state for the advancement of protecting and enhancing our very important marine system.

There are currently a number of artificial reefs in Hernando County which include but are not limited to, Bendickson Reef where there are 10 M60 army tanks placed in 1995, these are now overgrown with sea and fish life. Permits were recently approved and an additional 600 tons were added to the reef. Monitoring will be provided by FWC and Florida Department of Environmental Protection (FDEP), and US Army Corp of Engineers (ACOE). The Florida artificial reef program is the only state program that is not exclusively run at a state agency level. FWC depends on its partnership with local counties to hold reef permits and manage new reef deployments.

Another artificial reef is reef project #1 which is a shallow reef project with 130 reef balls in 3 different spots. These aHre carefully researched locations. Monitoring is planned for April 15th by the Scubanauts, who are coming to assess the fish populations and new life growing on the artificial reef. The Scubanauts are students in a marine science education for young men and women, ages 12-18. These young marine scientists receive informal science education through underwater exploration focusing on diving experience, and personal development. Hernando County is fortunate to have these young scientists available to assist our community in our marine research.

Hernando County is also in the process of investigating 20 different sites where the next batch of material will be placed. The reef ball material is available and site planning and permitting is ongoing. Permitting is the responsibility of the ACOE in federal waters and by both the ACOE and the FDEP in state waters. Both agencies work with the FWC during the artificial reef application process. Sponsorships are now being offered through the Hernando Environmental Land Protectors (HELP). HELP is a not-for-profit corporation created in 1976 and is one of the oldest established environmental organizations in Hernando County. Through this organization, an individual or business can sponsor a reef ball. The reef balls will include permanent commemorative plaques and the location coordinates will be provided to the sponsors so they may visit their reef in the future. The sponsored reefs will also provide educational opportunities, as well as great fishing spots. All deployments will be monitored by Scubanauts International and data analyzed by the students of the University of Florida and other research institutions. Artificial reef projects are monitored by a variety of sources such as the Scubanauts, and sonar imaging of the seafloor and remotely operated underwater video. These assessments include fish censuses and mapping, reef spacing and design, material stability, storm impacts and comparisons of artificial reef fish communities with those on adjacent natural reefs.

Approval has also been received for development of an oyster reef and habitat restoration project in Centipede Bay. Research has proven that placement of oyster shell in bags will stimulate the growth of juvenile oysters, improve water quality and reduce shoreline erosion. On March 11, community volunteers loaded bags of specially processed and disinfected oyster shell to be returned to the sea for oyster regeneration. This was sponsored by UF /IFAS extension. Oyster beds are dying in the state of Florida because of freshwater intrusion and lack of nutrients. Hernando County has a rich area of nutrients. The tentative launch date for the oyster beds is April 2018.

Florida is responding to fisheries and habitat decline with one of the nation’s most progressive artificial reef program, with Hernando County being one of the leaders in the state.

SCUBAnauts volunteers assist with artificial reef project off Hernando coast


Hernando County’s multi-part plan to boost local waterways through artificial reef projects kicked off last month when more than 600 tons of concrete material were dumped into the Gulf of Mexico atop the existing Bendickson Reef.

On Sunday, the second part of the project — involving reef balls, or man-made concrete structures used to repair ailing reefs and promote healthy habitats for fish — got moving, too, much of it with the help of some unlikely volunteers.

Seventeen youth ages 12 to 18 from SCUBAnauts, a local marine science education program founded in 2001, gathered in Hernando Beach to create four reef balls to be dropped into the gulf next month.

County Commissioner Wayne Dukes says the structures will find their resting place in shallow waters, creating a reef fit for recreational activities, like fishing, snorkeling and diving, to help the county to live up to its newly adopted “Adventure Coast” slogan.

He says data from the state shows an $8 dollar return on every dollar spent on artificial reefs, resulting from increases in commercial and recreational water activities supported by the expansions.

“This is going to bring a lot more recreational opportunities to Hernando County, and that is good for the quality of life of our residents and tourists,” he said.

Dukes tipped his hat to the SCUBAnauts volunteers, whose involvement in the county’s plans began months ago, when they were enlisted by county waterways manager Keith Kolasa to do standardized underwater surveys of proposed reef sites.

While waterway projects are mostly fueled by the county’s $14 million BP settlement from the 2010 Deepwater Horizon oil spill in the gulf, county officials say those dollars are still stretched tight and only available in increments over a 15-year payout period.

Without SCUBAnauts, the county would have had to hire scientists to survey the sites for information required to get project permits and move forward, while services from the group were free.

“I give them all the credit. … They have helped us tremendously through this whole process,” Dukes said. “Their volunteer services have saved us both time and revenue.”

SCUBAnauts president and CEO Paul Foisy said in his mind, the partnership helps his organization just as much as it has helped the county.

“This isn’t something your typical teenager does, and a lot of them don’t even realize the magnitude of what they are doing,” Foisy said, adding that the group also does regular survey work in the Florida Keys. “We are all about hands-on experience. … This is that.”

SCUBAnauts member Diana Phillips, 15, said the best part about helping communities like Hernando County with waterway projects is knowing how long-lasting her work will be.

“Us being kids and being able to make something that will last hundreds of years is a big deal,” Phillips said. “It’s good for our future and the community’s future at the same time.”

Much of the funding for Sunday’s project came from 19-year-old Cole Kolasa, son of Keith Kolasa and a longtime SCUBAnauts member who now attends the University of Central Florida. Over the summer, he kayaked from the Florida Panhandle to the Everglades while blogging and collecting donations for the county’s reef projects.

Kolasa raised about $3,200, which was used to purchase the four reef ball molds used by SCUBAnauts, as well as concrete and other materials.

Once the reef balls are dropped, Foisy said, the SCUBAnauts members will return regularly to monitor them. Kolasa, a sophomore marine biology major, said he will, too, and hopes to have the university study the sites and their effect on seawater in the area.

“It’s really exciting what is happening, especially because I grew up in Hernando County and now I am able to do research and actually be able to make a difference and see results,” he said. “I’m excited to see change actually happening.”

Texas, coastal flooding from Harvey

There are some Reef Balls that seem to be way underwater along the texas coast.   One of the sites I have been watching is Oyster Lake.  The image below shows a lot of sediment moving down the rivers and into the Gulf.  My hope is to find that the Reef Balls have captured a lot of sediment.  Time will tell.


There is a sequence of before and after that is also interesting as the image of the day.    That link will probably change over time.

Tilghman Manmade Reef to Double in Size

On Wednesday, 140 concrete reef balls will be planted on the Tilghman Reef, off Tilghman Island.

The reef balls were built by students in STEM education programs, in Carroll and and Anne Arundel counties as well as Vienna, Virginia. The addition of the new reef balls will double the current size of the reef, making it one of the largest man-made, three-dimensional reefs in the Maryland part of the Bay.

The Coastal Conservation Association (CCA) Maryland and Northern Virginia Chapters and the Building Conservation Trust, CCA’s National Habitat Program, will plant the reef balls.

Half of the 140 reef balls being deployed this summer were set with oyster spat. When the reef was started a year ago, just 72 reef balls were deployed. Stevenson University scientist Dr. Keith Johnson is monitoring the reef. Dr. Johnson estimates there were up to 2,000 juvenile oysters in each reef ball that was deployed last July.

The reef provides habitat for fish, oysters and other filter feeders. It also attracts fish, making it a great spot for recreational fishing.

Coastal Conservation Association Maryland posted this sonar shot of the reef ball deployment from July 2016. Just one year later you can see the they are productive habitat holding fish.

A broad partnership led by the Maryland and Virginia chapters of the Coastal Conservation Association, a group of recreational anglers, dumped nearly 150 of them overboard just off the shores of Tilghman Island. They were laid alongside 72 reef balls that were dropped last year.

The project united the anglers with environmentalists, business sponsors and students for a common objective: cleaning the Chesapeake for the sake of its ecology and for its economic power.

The strategy for restoring the bay’s oyster population has become divisive in recent years, with debates over where watermen should be allowed to harvest and how much of the shellfish population should be held in sanctuary.

Projects such as the Tilghman Island reef show the industry and science don’t have to be at odds, said Del. Robert Flanagan, who joined Schoberg and two Carroll County teachers Wednesday to watch the new reef be built.

“We can have sanctuaries and still have this thriving industry,” the Ellicott City Republican said. “We can do both.”

The Coastal Conservation Association funded the $20,000 project largely through its Building Conservation Trust, a program that aims to restore or create new habitats for fish and other marine organisms.

It pulled in the support of groups such as the Chesapeake Bay Foundation whose ship, the Patricia Campbell, was used to ferry and drop the reef balls, and companies like Lehigh Heidelberg Cement Group, which supplied the concrete, said David Sikorski, executive director of the association’s Maryland chapter.

And they employed the labor of students from across the bay watershed — including a handful of Carroll County schools, the Anne Arundel Center For Applied Technology North, and James Madison High School in Vienna, Va.

About half of the reef balls planted Wednesday were each covered in about 2,000 baby oysters, grown by the bay foundation at its Oyster Restoration Center in Shady Side. That made them already a dingy gray as the ship’s crane lowered them into the bay, four at a time.

Students made the reef balls with fiberglass molds developed by Georgia-based nonprofit the Reef Ball Foundation. They mixed the concrete, poured it in the molds and waited for them to set.

Underwater surveys and photos of last year’s reef balls show an area of bay bottom that would otherwise be barren sand is teeming with life. They are part of an 84-acre artificial reef that also contains bridge decking, tires and granite, according to the Maryland Artificial Reef Initiative, a program of the state natural resources department.

Allison Sweeney and Bethany Baer, fourth-grade teachers at Elmer Woolfe Elementary School in Union Bridge, said the project came amidst lessons about bay ecology and water quality and about the history of Maryland’s seafood industry. The two tagged along Wednesday to snap photos to share with their students.

“In social studies we talk about the job of the bay,” Sweeney said. “We talked about how our natural resources affect what we can do in our society.”

The lessons stuck with Schober. She remembered seeing pictures of massive piles of oyster shells, from back when there were nearly 100 times more of the bivalves across the bay.

“Now there’s just barely any left,” she said.

But one of her favorite lessons was about the Chesapeake “Oyster Wars,” conflicts in the late 1800s and early 1900s between watermen and pirates who dredged for oysters illegally. That conflict, and the ongoing struggles of watermen on the bay, taught her the economic importance of oyster harvesting.

“You can’t say ‘don’t do it for a month,’ because some people make their money that way,” Schober said.
