Reef-building corals are the source of primary production in
reef communities through symbiosis with unicellular algae (zooxanthellae).
Biologically active compounds, produced by reef-dwelling organisms,
possess antimicrobial and antiviral activity. These compounds
may be important sources for natural product-based drugs and medicines.
Tourists attracted to the beauty of coral reefs can be a significant
source of revenue for communities in those areas. Unfortunately,
as our understanding of coral reefs increases, it becomes apparent
that the effects of human population on these communities may
be increasing as well. Creating and deploying artificial reefs
is one effective way groups like the Organization for Artificial
Reefs, Inc. (OAR), are taking steps to help alleviate damage caused
by humans.
The Organization for Artificial Reefs is a diverse group of volunteers
dedicated to conserving and enhancing the marine environment of
Florida's Big Bend coast and beyond. The organization, founded
in 1986, is based in Tallahassee, Florida. OAR's growing membership
of nearly 300 makes it Florida's largest private, non-profit organization
involved in the development of manmade marine habitat. A growing
list of accomplishments also makes OAR one of the most successful
of these groups.
What is an artificial reef?
An artificial reef is any structure placed by man in the marine
environment. Properly prepared and strategically located, they
attract marine life of all kinds.
Who, or what, is OAR?
The Organization for Artificial Reefs, Inc. (OAR) is a private,
501(c)(3) nonprofit group of marine enthusiasts and artificial
reef advocates, based in Tallahassee. OAR serves the recreational
saltwater fishing community of Florida's Big Bend Gulf Coast by
promoting the professional development of public artificial reefs.
OAR is committed to responsibly designing and deploying artificial
reefs as a means of protecting and
enhancing a variety of marine life for the sake of both biodiversity
and for promoting the enjoyment of the
saltwater environment by the sport fishing and sport diving communities.
Primarily relying on volunteers, OAR is made up of a dues-paying
membership base that is called upon to carry out various duties.
A non-paid coordinator and an 11-member, non-paid board of directors,
which holds monthly meetings open to all members, govern the organization.
OAR strives to operate at every level as a professional organization
with highly cultivated ties to key organizations and leaders in
federal, state and local governments.
How was OAR started? By an individual, a group or due to legislation?
OAR was started in 1986 by a group of local marine enthusiasts
who saw the need to create much needed habitat in the Northern
Gulf for the purpose of reducing the stresses placed on natural
habitat, and to create more recreational fishing and diving opportunities
for both residents and tourists.
How do you obtain the money to operate and produce these reefs?
For operating funds, OAR relies on a variety of sources, including
membership fees, proceeds from the sale of internally produced
products, private tax-deductible donations, and government grants.
Also, OAR's primary annual fundraiser is the Big Bend Saltwater
Classic fishing tournament. Established in 1989, our tournament
has grown into the largest saltwater fishing tournament operating
on the northeast Gulf Coast.
How do you determine the location for a new reef?
OAR determines suitable locations for new artificial reef construction
by utilizing the organizationÕs volunteer Research Dive
Team (RDT). This group of specially trained divers is skilled
in conducting the types of underwater work essential to the creation
of artificial reefs. The RDT dives and evaluates possible locations
looking for suitable bottom conditions. Bottom conditions play
a very important role in the development of new reefs.
Suitability for a new reef site is determined by the RDT probing
the sea bottom and noting the depths of the underlying substrate
to bedrock, as well as the absence of significant marine habitat
such as sea grasses, hard or soft corals, exposed and encrusted
limestone, other than sand and granular sediments.
How long does it take, from the planning of a location, to actually
dropping the material into the water?
Typically, it takes OAR around one year to create a new artificial
reef. The site must first be evaluated, scientific data must be
collected by the RDT and submitted with the assistance of a local
government to the Army Corps of Engineers (ACOE) for the purpose
of obtaining the permit before construction can take place. The
permitting process, on average, takes OAR approximately 6 months.
Once the permit has been obtained, OAR determines the funding
sources available to create the reef, and then subcontracts the
actual deployment of the reef.
What methods are used to deploy the materials?
Deployment methods vary from reef to reef. The methods are determined
by the materials being deployed and the navigational clearance
required as part of the ACOE permit.
Who deploys the materials?
OAR currently subcontracts out all of its reef-deploying activities.
OAR, with assistance of local governments, sends out requests
for bids to various reef builders in the area. Typically, the
lowest bid is awarded the contract to deploy.
Is there a particular guideline you follow for the layout of
the materials on the ocean floor?
OAR creates reefs that are complex in both structure and deployment
pattern. Materials are selected in an effort to create a truly
balanced reef that provides a complex habitat providing shelter
for a wide range of marine fish and invertebrates. The reef spacing
and distribution have been designed to maximize this potential.
Following the belief that an underwater structure provides a safe
shelter for marine species, each group of materials is spaced
roughly twenty feet apart from the center of the reef in an effort
to provide an adequate foraging zone.
What are the best materials suited for artificial reefs?
There are a wide range of materials that can be used to create
an artificial reef. However, there are strict
guidelines as to what materials can be used. Currently, the only
permissible materials for deployment are either steel (vessels
and scrap) or concrete (bridge rubble, culverts, prefabricated
modules).
What are some styles of prefabricated habitats?
OAR has deployed reefs consisting of various prefabricated modules.
Most recently, OAR deployed
reefs constructed solely of modules produced by Artificial Reefs,
Inc. of Gulf Breeze, FL, called Fish Havens. These modules have
a vertical relief of approximately 8 feet and with a base of 10
feet on each of the modules, 3 sides. These modules are specially
treated during construction to allow for rapid growth. Other modules
such as reef balls, produced by the Reef Ball Foundation (www.reefball.org),
and Lindberg Cubes designed by Dr. William Lindberg from the University
of Florida, have also been used.
How many reefs has OAR built to date?
Approximately 20 reefs have been built to date.
How long does it take for fish to inhabit a newly built reef?
Some fish move into a new reef within hours of deployment. Most
of these are ornamental fish. Sport fish
such as grouper, snapper and pelagics, usually start moving in
within days, sometimes weeks, of deployment. It's hard to tell
for sure, because the reef is typically not monitored until weeks
or months after the actual deployment date.
What is the largest reef that OAR has deployed?
The largest to date is the Bryson Memorial Reef (1998). This reef
consists of two steel hull vessels as well as hundreds of tons
of concrete culverts.
How can the public obtain the locations of the various artificial
reefs in their area?
The locations of all artificial reefs deployed in the State of
Florida can be located on the Florida Wildlife
Conservation Commission's Marine Fisheries Web site:
http://marinefisheries.org/ar/index.htm
How much do your reefs impact the sport and recreational fishing
economy?
Recent studies conducted in the Florida Panhandle have shown that
for every $1 spent on artificial reefs, the conservative overall
socio-economic benefit of the artificial reef system, throughout
its estimated functioning life, was estimated at $138.
Are there other organizations like OAR in Florida?
There are other groups throughout the state that operate similarly
to OAR. However, several of these groups are part of large coastal
counties and municipalities that have their own artificial reef
programs and budgets.
Can anyone get involved with the OAR? If so, who should be contacted?
Anyone and everyone is invited to become a member of OAR. For
