- Overview of Southwest Florida Estuaries
Presented by Gary Lytton
Environmental Administrator, Rookery Bay Reserve
An estuary is a coastal basin in which fresh water from rivers and streams mixes with
ocean salt water. Estuaries are highly productive and diverse ecosystems, providing
essential habitat for wildlife, and supporting important economic benefits to coastal
communities. Collier County's estuaries include Clam Pass, Naples Bay, Rookery Bay,
and the Ten Thousand Islands. These estuaries range from urbanized coastal bays (e.g.
Naples Bay) to relatively pristine environments (e.g. Rookery Bay).
Key emergent and submerged plant communities in Southwest Florida estuaries include
mangroves and seagrasses. Mangroves, with three species in Florida, are trees capable
of living in salt water. The region's mangrove forested wetlands provide important
functions for coastal environments: refugia for wildlife, nursery for recreationally and
commercially important fish and shellfish, and an important source of food that fuels
biological productivity along the coast. Detritus, or decomposed plant matter in the form
of mangrove leaves, seagrasses and other wetland plants, provide an important energy
source that serves as the foundation of the estuarine food web. Seagrass beds provide
similar functions as refuge, habitat and food source for fish and shellfish. Coastal plant
communities support a rich biological diversity in Collier County: 227 species of fish,
150 species of birds and 460 species of plants.
Economic benefits from estuaries are linked to the high productivity associated with
healthy coastal environments. For example, commercial landings in Collier County for
2002 (fin fish and shellfish combined) totaled over 4 million pounds and generated $11.7
million dollars. In 2001, there were over 22,000 registered boaters in Collier County.
Recreational boating generates millions of dollars in revenue through sales of boats, boat
rentals, fuel, fishing tackle and related items. Ecotourism is an increasingly important
business that is linked to conservation of coastal resources.
High biodiversity and productivity of estuaries in Collier County are linked to fresh water
inflows that drain fi.om connecting watersheds, or drainage basins. Historically,
seasonal rainfall flowing downstream to estuaries filtering slowly through wetlands
concentrated within a series of flow ways, or shallow depressions that capture and direct
surface water to the coast. Research has linked healthy estuaries to the timing, volume,
and quality of flesh water flowing downstream from watersheds. Key estuarine species,
such as shrimp, redfish and blue crabs have adapted their spawning cycles to the natural
seasonal changes in salinity of the estuary.
Key issues or threats to Collier County's coastal estuaries include:
Loss of coastal habitat: Coastal development in Southwest Florida has resulted
in direct impacts to estuarine environments from dredging, resulting in significant losses
of wetlands such as mangroves and seagrasses. In Tampa Bay, 44% of the emergent
10
promoting informed decisions
wetlands and 80% of seagrasses were lost, resulting in the collapse of important local
fisheries.
Watershed alterations: Changing land use within watersheds has resulted in
significant impacts to natural fresh water fiow regimes to the region's estuaries. Timing,
volume, and quality of fresh water have been changed as roads, canals, and other land
uses alter the natural landscape. These changes interrupt spawning cycles offish and
shellfish, and result in loss of plant communities (e.g. seagrass beds).
Stormwater runoff/Water quality: Urban development along the coast can
result in significant increase of impervious surfaces (e.g. roads, parking lots, etc.) that
eliminate the natural filtering action of wetlands. Runoff from storms and seasonal rains
carries pollutants (e.g. oils, pesticides, fertilizers) directly to estuaries. Runoffto coastal
waters can alter natural water quality conditions, causing algal blooms and fish kills as
eutrophication occurs. Thirty (30) beach closings in Collier County occurred due to high
fecal coliform between August 2002 and April 2003.
Non-native invasive plants/animals: The native biodiversity of the County's
coastal environment is threatened by the introduction of non-native species of plants and
animals. Non-native invasives, such as Australian pine and Brazilian pepper, out-
compete native plant communities and eliminate habitat for native wildlife. Following
the removal of 300 acres of Australian pines from Key Island, there was a notable
increase in loggerhead turtle nesting.
Public use: Collier County residents and tourists access coastal environments
ranging from barrier beached to inland bays. Public use and enjoyment of the County's
coastline contributes to both a higher quality of life for both residents and non-residents,
and to a stronger local economy. Monitoring has indicated, however, that significant
impacts are occurring from over-use and lack of public awareness. Seagrass beds are
scarred from outboard engine props, barrier island beaches are littered with trash,
manatees are injured or killed by unaware boaters, and seasonal shorebird nesting areas
are lost to unwary beach goers.
Catastrophic storm events: Hurricanes and tropical storms have occurred over
thousands of years along Southwest Florida's coast. Catastrophic storms act as change
events for coastal ecosystems, altering the configuration of barrier islands and tidal inlets
and causing changes on short-term (e.g. wetlands loss) and long-term (e.g. tidal flushing)
scales.

Connecting Science to Management
Presented by Dr. Michael Savarese, Florida Gulf Coast University
Presentation Outline
1. Purpose of this presentation.
This short presentation has two purposes. First, the scientific method will be
reviewed and its role in coastal resource management will be explained. Second, the
method's strengths and limitations will be reviewed and the implications for management
decisions explored.
2. Tools of the decision maker.
Management decisions are affected by numerous factors, only one of which is
scientific data. First and foremost, however, management decisions should be supported
by the best science available. Beyond this other factors can constrain or influence
management decisions. For example, legal issues may prevent certain decisions from
being implemented or economic constraints may prohibit certain solutions. Finally,
management decisions are influenced by the wishes of the decision-maker's constituency.
3. The scientific process.
Science is often misconstrued as a collection or catechism of facts when in reality
science is a process through which the natural world is studied. The process follows a
rigorous and formal protocol. First, a hypothesis, a suspected statement of fact, is posed
that is ultimately subjected to scientific testing. A hypothesis may be negated or falsified
through the making of inconsistent observations. Alternatively the hypothesis may be
corroborated by amassing supportive evidence. After the hypothesis is generated, an
experiment is designed, predictions concerning the outcome are made, and the
experiment is conducted. Data are collected and analyzed, and the results are interpreted.
If the interpretation is consistent with the hypothesis, then the hypothesis remains viable.
If the interpretation is not consistent, then the hypothesis is falsified and discarded.
Finally, to ensure quality and objectivity, all scientific studies are subject to peer review
before results are made public.
4. Difficulties studying environmental science.
Environmental science is complicated by a number of factors, resulting in a
lessened confidence in the outcome. First, ecosystems are dynamic and change over
short time scales. This makes the characterization of an ecosystem's state problematic.
Second, ecosystems are governed by numerous, interdependent factors, making it
difficult to isolate specific causes and effects. Third, the state of an ecosystem is a
consequence of history. Numerous, pre-occurring historic phenomena have affected the
composition and state of an ecosystem. Accurately predicting an ecosystem response in
the future requires an understanding of that history, something rarely known by the
investigator. Fourth, the study of environmental science often requires immense amounts
of time, time not available for the purpose of management. And lastly, ecosystems are
difficult to study experimentally because they are hard to control and manipulate. All of
promoting informed decisions
13
these factors contribute to a greater level of uncertainty in the results than what is
experienced in other scientific disciplines.
5. As a consequence...
Even the best environmental science can result in high levels of uncertainty.
Often hypotheses are supported but they require additional testing. At times best efforts
establish a correlation between two phenomena without necessarily establishing a cause
and effect relationship. Ultimately then science is not necessarily a panacea. Yet within
these limitations, and with foresight, science can "get the job done" and sound
management decisions can result.
6. Implications for management.
Best science should be employed whenever available before management
decisions are made. If the level of uncertainty is low and the science community has
great confidence in the results of the hypothesis test, then the management alternatives of
choice should be clear (assuming no other compromising factors; see point 2 above).
When uncertainty is high and the hypothesis test results are weak, then management
decisions should be conservative and err on the side of greatest societal benefit.

Mosquito Control Example of Adaptive Management
Presented by Dr. Michael Shirley, Research Director, Rookery Bay NERR
Scientific research plays a key role in adaptive management, which is an
emerging goal of many of today's management programs for coastal natural
resources. Research gives quantitative, objective information on the success or
other impacts of a management strategy, supplying feedback on the need for any
alterations or new considerations. As stated in the previous presentation,
scientific research may be one of many sources of information that need to be
considered before adapting management strategies.
To illustrate a real life example of the role scientific research plays in adaptive
management, we will discuss a recent project conducted at the Reserve in
partnership with Collier County Mosquito Control.
Mosquito Control regularly treats a residential area east of C.R. 951 and adjacent
to the core area of the Reserve along Henderson Creek. When researchers began
finding large numbers of dead fiddler crabs in the Reserve, anecdotal evidence
suggested that the mosquito pesticide might be the cause.
Researchers contacted Mosquito Control to inform them of their concerns.
Working together, the two agencies coordinated a research program to monitor
the effects of pesticide application on fiddler crab populations.
RBNERR scientists set up research stations to monitor both fiddler crab mortality
rates and pesticide deposition on the ground.
Data from the monitoring stations indicated that the mosquito control pesticide
was the cause of high fiddler crab mortality rates and that pesticide problems
within the Reserve were occurring when the wind patterns caused significant drift
across Reserve boundaries. In addition, data showed that a large portion of the
pesticide was being lost to rapid ground deposition, indicating ineffective
mosquito control efforts.
As a result of the research, the decision was made to adapt the treatments by
flying an offset pattern to adjust for wind drift in order to target the proper area
with pesticide. Continued monitoring showed that crab mortality was decreased,
but continued environmental problems were still occurring. Large amounts of
pesticide were still quickly depositing on the ground, causing non-target impacts
and inefficient mosquito control.
To gather additional information, a second round of studies were conducted using
different chemicals and application techniques to investigate the possibility of
more successful application methods.
promoting informed decisions
15
As a result of the study, researchers recommended using a different pesticide and
a modified spray nozzle. This new combination created a finer aerosol that stayed
airborne and killed more mosquitoes with less pesticide.
After implementation, there was no fiddler crab mortality, and Mosquito Control
was killing more mosquitoes with less pesticide, thereby reducing their
operational costs.
This successful example illustrates the benefit that science can have when
appropriately applied in coastal management. By formally incorporating and
supporting research in management programs from the outset, science can provide
valuable feedback on the natural resources that are being managed. This feedback
is then one part of a step-by-step process that incrementally improves
management practices through consideration of all parts of the puzzle.

Water Quality Monitoring: Managing for Optimal Diversity
Presented by Dr. Michael Shirley, Research Director, Rookery Bay NERR
The physical and chemical properties of water naturally vary to a large degree,
especially in coastal and estuarine areas that are influenced by watershed
drainage, tidal mixing and weather patterns. Poor water quality usually means
that one or more of these properties are far enough outside the normal range to
negatively effect the local community. These may be direct effects such as toxins
or pollutants that affect human health or decreased aesthetic appeal to residents
and visitors. But, they may also be indirect effects, such as the degradation of
other desirable natural resources (such as fisheries) that depend on certain water
conditions.
Managing water quality is challenging due to the variety of potential causes for
any impact. Identifying the cause of water quality impacts is often difficult
because coastal waters are receiving areas from large watershed drainage basins,
but are also significantly affected by offshore conditions. Likewise, managing
these impacts, particularly when they span large distances, is also challenging and
highlights the need for coordination and communication among local
communities.
When water quality issues are relatively direct, such as pollutant-related health
hazards, the management goals are also relatively direct - clean out the problem
pollutant. However, it is important to also consider long-term goals for managing
coastal water quality and its effects on the biology of the coastal area. In some
areas, such as those dominated by an important fishery, water quality
management aims to optimize a particular species or resource. However, it is also
possible to manage water quality for the coastal ecosystem as a whole, by
maintaining water quality that sustains maximal natural biodiversity within the
ecosystem.
By maximizing natural biodiversity, communities are likely to support fisheries
and other desirable natural resources that were historically abundant. In addition,
the waters will more likely support other species that, although little may be
known about them, may play an important ecological role. Finally, a healthy,
diverse ecosystem is generally considered more robust and able to recover from
large disturbances such as storms or disease outbreaks.
These biological goals are indirectly achieved by managing physical and chemical
water properties in a way that approximates the natural state prior to being
impacted. This is best accomplished by managing properties such as salinity,
temperature, pH, dissolved oxygen, and turbidity (the amount of suspended
particles in the water,), which most directly affect the biology of the system.
The success of a monitoring program is largely dependent on having been
correctly designed to give the necessary information. Because water properties in
18
promoting informed decisions
coastal areas vary over very short time periods (minutes to hours,) biologically
important changes in water quality can happen very quickly. Automated data
recorders can be used to sample the water periodically (every few minutes) and
store the readings for regular download. These systems can efficiently gather far
more detailed data than traditional manpower-based sampling programs. As a
result, they can often catch very important short-term changes or events that are
missed when data are acquired less frequently.
Results of these monitoring systems have shown important differences in various
coastal bays in Collier County. Although we know that the hydrology of different
bays has been altered to a different extent, monitoring programs have shown the
different effects of these alterations on water quality. By comparing these data to
differences in biodiversity in these bays, managers can determine what impacts
are affecting diversity and set water quality targets to help improve the biological
conditions.
Research programs also sometimes monitor biological components of an
ecosystem. All species have evolved to thrive in a specific suite of water quality
conditions, and some of these can tolerate a much wider range of conditions than
others. Improved understanding of these tolerances can help researchers try to
predict the success of different species and changes in biological communities
that may occur as a result of different water quality conditions. In addition, when
much is known about the physical requirements of a particular species, its
abundance (or its absence) can offer additional insights into physical water quality
characteristics or changes that may be occurring. Thus, biological monitoring
becomes another tool to help illuminate the complex interactions that affect
successful management of coastal ecosystems.

Estuarine Health: Habitat and Fisheries
Presented by Dr. S. Gregory Tolley, Florida Gulf Coast University
Estuaries are created where fresh and salt water meet and then mix to varying
degrees. Due to their unusual characteristics-freshwater inflow, relatively high nutrient
input, and mixing due to tides and winds-estuaries are some of the most productive
ecosystems in the world. Nevertheless, there is a cost to living in such a productive
environment. These systems are subject to constant change: tides and freshwater input
working together challenge species normally adapted to living in waters with stable
salinities, an environment that allows for easier maintenance of internal water and salt
balance.
Yet, there is a growing consensus among scientists and resource managers that a
significant proportion of commercially and recreationally important fishery species in the
eastern United States depend upon estuaries to provide nursery habitat for developing
young. These species can be said to be estuarine dependent to varying degrees: a small
number of species have actually developed the survival skills necessary to live in the
continuously changing estuarine environment year in and year out (e.g., spotted seatrout);
however, many species that spawn at sea or along the coast have young that move into
estuaries to take advantage of nursery habitats there (e.g., snook, red drum). It seems that
for many of the latter, the young are better able to tolerate changing estuarine conditions
than are the adults. In extreme cases, the young of some species actually travel far
upstream in the estuary to be the first in line to take advantage of the abundant food
available there.
Those species able to successfully invade the estuary are well rewarded. Young
fishes find a variety of habitats there-seagrass beds, mangroves, marshes, tidal creeks,
oyster reefs-that provide food and shelter from predation. The importance of these
habitats to coastal fisheries cannot be underscored enough: for example, the size of the
commercial harvest for estuarine-dependent species has been linked to the amount of
marsh habitat available within an estuary. As the young of these estuaxine dependent
species grow and move into higher salinity waters, they provide a vital food and energy

Figure 1. Schematic diagram of the effects of freshwater inflow on estuaries
(Alber 2002~
As we begin to understand more fully how esmarine ecosystems function, we are
beginning to realize the significant role that freshwater inflow (i.e., the amount, timing,
and quality of freshwater) plays (Figure 1). For many coastal fisheries, productivity is
related to freshwater inflow. Catches of shrimp, blue crabs, seatrout, and red dram appear
to be greater in years preceded by higher levels of freshwater input into estuaries. In
contrast, sustained high freshwater inflows into Apalachicola Bay in the Florida
Panhandle result in reduced oyster harvests. At a time when major ecosystem replnmbing
efforts are underway in South Florida as part of the Comprehensive Everglades
Restoration Plan, the consideration of the availability of freshwater for estuarine
ecosystems and ultimately for coastal fisheries has never been more important.

..... Florido Red Tides
Presented by Beverly Roberts, Research Administrator, Florida Marine Research Institute
What are they and what effects do they produce?
Red tide is actually a bloom of a type single-celled planktonic plant called a
dinoflagellate, with the scientific name of Karenia brevis. This dinoflagellate is most
likely always in Florida waters, but does not cause a noticeable impact until
environmental conditions are right to foster its growth to relatively high levels. There are
many different types of microscopic algal organisms and blooms, and they play a very
important part in the food web of coastal waters. However, the dinoflagellate that causes
red tide also produces a toxin, which, at high levels, causes many of the undesirable
effects that these events have come to be famous for, including:
water discoloration
· respiratory irritation
· contact dermatitis
· infections fi.om punctures
· mortality of fish and other marine animals
· accumulated toxins in animals such as bivalve mollusks (including commercial
shellfish) and tunicates
· human illness
How can we manage them?
Historical records indicate that red tides have occurred for hundreds of years. There is
also considerable scientific evidence to indicate that red tides are a natural offshore
phenomenon, only affecting the coast when wind patterns drive the bloom into inshore
waters. However, scientists are currently investigating whether land-based nutrient
pollution may increase the duration or intensity of red tide events once they move
inshore. Therefore, it does not appear to be something that can be largely managed by
land use decisions along the coast. There are however, opportunities for communities to
manage local effects of red-tide, including:
· information dissemination
· response protocols
· monitoring
· fish removal
· Further research initiatives that investigate:
° public health
· prediction
· mitigation & Control

The Florida red tide is a naturally
occurring phenomenon that con-
tinues to challenge researchers
seeking clues to its origin and cause.

Florida's Gulf Coast since the 1840s

and probably occurred much earlier. Fish kills around
Tampa Bay were mentioned in the logs of Spanish ex-
plorers. The source of these red tides--a group of tiny,
plant-like organisms called dinoflagellates--was not
discovered until the massive red tide of 1946-47 In
southwest Florida.
Description
Red tides with various characteristics have been docu-
mented worldwide for thousands of years in cold tem-
perate to tropical waters. Dinoflagellates, the organisms
that cause most red tides, are microscopic, single-celled
organisms characterized by two whiplike structures,
each called a flagellum. One flagellum spins the cell
around and the other propels it through the water at
about three feet per hour. Dinoflagellates and other
types of microscopic algae, collectively called "phyto-
plankton," are commonly referred to as the "grass of the
sea" because they are so plentiful and have plant-like
nutritional characteristics. They use the sun's energy to
produce their own food and, In turn, are eaten by many
other kinds of marine life. In this way, they serve as a
Florida Marine Research Institute
foundation for the marine food web.
Dinoflagellates can produce
some of the most powerful poisons
in nature. When certain dinoflagel-
lates are present in higher-than-
normal concentrations, a "bloom" is
created that releases poison, or toxin, into the water.
This toxin can cause various effects; for example, it may
paralyze fish, causing them to stop breathing. Some-
times, a bloom discolors the surrounding water. The
color may be red, but a bloom may also be yellow,
orange, brown, or reddish-brown.That's why scientists
prefer the term Harmful Algal Bloom (HAB).
Scientists prefer to call red tides Harmful
Algal Blooms, or HABs.
In Florida, the most common cause of red tides is
a toxic marine dinoflagellate named Knrenln brevls (fre-
quently abbreviated to K. brevis), which is a yellow-green
dinoflagellate measuring only about ~/iooo of an inch long.
A stingray-shaped single cell, it contains one flagellum
encircling a groove around the middle of the cell and
a second flagellum trailing behind like a ship's rudder.
The cell's forward morton resembles a gently falling leaf,
turning over and over in the water as it swims, but/4.

Red tides can kill fish and other marine animals and contaminate shellfish such
as clams and oysters. People can become ill by eating shellfish tainted with red
tide toxins; additionally, toxic particles in sea spray at the shore can cause respi-
ratory discomfort.
brevis Is a weak swimmer and progresses mostly by
drifting along with currents.
Like other dinoflagellates,
K. brevls reproduces by cell
division, with a single cell
splitting into two about every
48 to 120 hours. In addition to
a dividing cycle, K. brevis has
a sexual cycle that may include
"resting" stages whereby it
could remain inactive during

always present in Florida marine waters at very low
levels of less than or equal to 1,000 cells per liter (ap-
proximately equal to one quart) of water. Periodically,
due to a combination of environmental or biological
conditions, K. brevis can accumulate in concentrations
of up to millions of cells per liter. Water samples col-
lected during a red tide that plagued southwest Florida
in 1995 and 1996 contained over 20 million cells per
liter. Counts exceeding I00 million cells per liter have
been recorded.
Scientific research shows that the growth of g. bre-
vis is influenced by a variety of factors, including
sunlight, temperature, salinity, and the amount and
types of nutrients available in the water. Winds and cur-
rents also play a role in determining when and where
blooms will occur. Studies indicate that K. brevls prob-
ably blooms annually in offshore waters as part of its

normal growth cycle. It becomes a problem for people
only when winds and currents drive the blooms close
to shore, where they can be concentrated.
Because Florida red tides caused by K. brevis start
offshore, one theory is that pulses of warm water from
the Caribbean moving Into the deeper waters of the Gulf
of Mexico may "awaken" K. brevls and spark a red tide
bloom. Another theory is that another phytoplankton
organism precedes g. brevis and conditions the water
for red tide growth.
People frequently ask whether red tides are a re-
sult of increasing pollution of coastal waters. Although
excess nutrients associated with human activities have
been linked to red tides caused by other species in en-
closed areas in Japan, Europe, and elsewhere, there is
no evidence to suggest a similar connection between
pollution and Florida's offshore K. brevis blooms. K. bre-
vis red tides begin offshore and have occurred in the
Gulf of Mexico for hundreds of years, long before man-
made pollution became prevalent. However, pollution
can cause other types of algal blooms in Florida's
coastal waters and estuaries, and researchers are
vestigating the possibility that pollution or nutrient
enrichment may influence K. brevis blooms after the
blooms are transported and concentrated inshore.
Didribufion
Karenia brevls red tides have been observed at least
once along almost the entire coastline of Florida. They
have also occurred at least once in the coastal waters
of the other Gulf states (most frequently in Texas) and
in Mexico. On the Atlantic coast, K. brevis has been
transported as far north as the Carolinas. Blooms occur
most frequently from August through February but.
have been documented in every month of the year.
Offshore surveys have shown that Florida red tides
generally begin 10 to 40 miles from the coast in the Gulf
of Mexico on the mid-continental shelf. Winds and
currents may push the patches of red tide onshore or
along the shore to other areas.
If conditions are right, a bloom may remain in an
area for several weeks or may move up and down
along the coast for months at a time. One red fide that
first appeared near Naples in November 1946 spread
as far north as Sanibel Island and Englewood by January
1947. Red tide surfaced again in the spring of 1947 in
outer Florida Bay and a few months later as far north
as Tarpon Springs. It was during this event, charac-
terized as one of the worst red tide episodes on record,
that scientists first identified K. brcvls as the toxic
organism responsible for Florida red tides.
flow Red Tides Affecf/ arine Life
Karenla brevis toxins, called "brevetoxins," primarily
affect the nervous system of fishes, causing death by
paralyzing the nerves and effectively suffocating the fish.
Karenia brevis can become lethal to fish at concentra-
tions greater than 100,000 cells per liter. This organ-
ism has been implicated in the mortality of marine
mammals, birds, and invertebrates during red tides
such as the one that occurred in 1996.
Although K. brevls red tides can kill thousands or
even millions of fish, there is no evidence that they cause
permanent damage to marine fish and invertebrate
populations. The impact of a red tide often appears to
be short-lived, and fishermen have reported better
catches of some species, such as crabs, in the months
following an outbreak. This may occur because the red
tide organism has killed specific predators, allowing
certain prey species to survive in greater numbers, or
because red tides introduce more food into the system.
Thus, although large numbers of fish may be killed by
a bloom, other species may benefit. Indeed, the ecosys-
tem currently in the Gulf of Mexico is composed of
populations that are the product of an environment that
has included red tides, storms, and other disturbances
for probably thousands of years.
The red tide bloom of 1946-47 is estimated
to have killed 500 million fish.
slow-moving fish, unable to flee from the path of
red tides, are usually the first to die, along with terri-
torial or bottom-dwelling fish. Nearly all fish are sus-
ceptible, especially if the bloom is dense or prolonged.
Invertebrates are usually not killed by red tide toxins,
although a greater variety of animals, including snails
and crabs, may be killed if the bloom Is severe enough.
Bivalve shellfish such as clams and oysters, which
feed by filtering plant matter from the water, may ingest
K. brevis and, consequently, become toxic to consumers.
Even when ~'. brevis concentrations are only slightly
above normal, these filter-feeders may become toxic If
they are exposed to Iow levels of toxin long enough.
In southwest Florida in 1996, an unprecedented
event of 149 manatee deaths was finally linked to a red
tide bloom that had extended into winter. As a result,
both the bloom and the manatees were present at the
same time in one of the manatee wintering areas. Red
tide toxin was found in the organs and stomach con-
tents of manatee carcasses. Given the results of detailed
examination of the carcasses, scientists hypothesized
that these animals died quickly after being exposed to
large quantities of toxin. Additional manatees died in
the winter of 1982 and in recent years during red tide
events; these animals also showed signs of exposure
to red tide toxin.
Flow Red Tides Affecf People
The greatest threat to humans posed by K. brevis red
tides is through consumption of bivalve shellfish that
have been contaminated with the red tide toxin. At
present, no humans have died from eating tainted
clams, mussels, oysters, or coquinas, but some people
have become seriously ill with an ailment called
Neurotoxic Shellfish Poisoning (NSP). Symptoms include
nausea, diarrhea, tingling of fingers and toes, and
sometimes a reversal of sensations--hot seems cold and
cold seems hot. Illness occurs within a few minutes to
several hours after consumption of the shellfish. NSP
is often confused with a more dangerous and commonly
known shellfish poisoning called Paralytic Shellfish
Poisoning (PSP). PSP Is caused by other dinoflagel-
lates that produce an entirely different set of symptoms
in humans.
As part of a routlne shellfish management plan, the
Florida Department of Agriculture and Consumer Ser-
vices closes harvesting areas when shellfish beds are
threatened by a bloom. The harvesting ban is lifted only
after meat from shellfish passes a laboratory test for the
toxin. Generally, most bivalves can purge the toxin from
their systems wlthin two to six weeks after the red tide
dissipates. The shellfish harvesting bans do not apply
to shrimp, crabs, or lobsters because the edible parts of
these and other crustacean shellfish do not become
toxic when the animals are exposed to Florida red tides.
Fish caught during K. brevls red tides show no ev-
idence of the toxin In their flesh and are safe to eat if
they are filleted. However, at any time, experts advise
against eating a fish that appears sick or lethargic.
People can also be affected by airborne toxins.
Wave action breaks apart the red tide cells, and the tox-
ins, associated with particles in the sea spray, cause
sneezing, coughing, and general respiratory irritation.
In addition, red tide can cause aesthetic problems in
coastal areas; it often dumps smelly, dead fish--some-
times hundreds or thousands of them--on area beaches.
Most local communities dispose of the rotting fish
quick]y, but these cleanups can be costly.
K. brevis is one of only a relatively few red tide
organisms known or suspected to produce
noxious, airborne toxic particles that can
irritate human respiratory systems.
Should flumans Seek lo Eliminate Red/ides?
Although it has long been debated whether research
should strive to find ways of eliminating or otherwise
controlling red tide, many scientists believe that there
is no practical way to totally eradicate Florida red
tides. Getting rid of red tide would be extremely diffi-
cult and costly because red tide blooms often occur over
hundreds to thousands of square miles of water, are
distributed throughout the water column, can be moved
great distances along the coast, and fluctuate daily
with the tides. The use of chemical or biological control
agents to disperse the red tide blooms or neutralize the
toxins may adversely affect other forms of marine life.
Yet, the possibility of controlling the bloom at a local
level, by mitigating either its effects or its distribution,
has recently gained popularity. Researchers are pursuing
the possibility of applying techniques that have been
used for limiting localized blooms of other species
elsewhere. Overall, scientists and managers agree that
we must be careful about introducing control agents into
our coastal system. Indeed, there is speculation that the
red tide phenomenon may serve an important, although
currently unverified, role in making the marine ecosys-
tem off Florida's coast more productive.
If red tides and their paths could be predicted,
alerted coastal communities might have time to mobi-
lize cleanup crews and establish warning systems
before the bloom arrives. With prediction as one of their
goals, numerous scientists are participating in a fed-
erally funded program called ECOHAB:Florida, a joint
effort involving the Florida Fish & Wildlife Conserva-
tion Commission (FWC), the University of South Florida
College of Marine Science, Mote Marine Laboratory, and
ten other university and federal laboratories. This group
has been studying how these blooms develop, grow, and
move. The use of satellites in detecting ocean currents
and blooms also holds promise for tracking the move-
ment of red tide and possibly predicting its occurrence.
The FWC and a number of other agencies and
research entities are acquiring scientific knowledge
about the Florida red tide organism in order to manage
its effects on humans and natural resources. Because
of FWC's long-term experience with this organism and
others, FWC scientists have made valuable contribu-
tions to investigations of harmful algal blooms.
This satellite Image, showing a bloom (light gray) in the Gulf of
Mexico off the southwest coast of Florida, is an example of how
satellites are used to detect and track red tides. The original image
uses colors to show different concentrations of red tide. These blue
arrows point to areas of greatest concentration.

Rookery Bay National Estuarine Research Reserve Visitor Study

School of Forest Resources and Conservation
University of Florida
Rookery Bay National Estuarine Research Reserve (RBNERR), located in an
extremely populated urban area in Southwest Florida, is a popular site for many types of
recreational activities. The seemingly unlimited opportunities, and lack of visitor
management, can both hinder a recreationist's experience and increase environmental
impacts. The object of this report was to identify visitor perceptions of impacts and
preferred management strategies, and create a helpful guide for managing for recreation.
The Rookery Bay Reserve composes over 12,500 acres [note announcement,
included in this notebook, of the recent boundary expansion that occurred after this study
was published], the boundaries of the Reserve have now expanded to include
approximately of diverse habitat, ranging from estuarine seagrass beds and mangroves to
coastal marshes and upland stands of pine, cabbage palm (Sabalpalmetto), and
hardwoods. However, Rookery Bay lies at the northern end of the Ten Thousand Islands
National Wildlife Refuge (TTINWR) and is surrounded by other publicly managed areas.
Therefore, this study took a regional approach to examining the Rookery Bay region -
recognizing that recreation visitors and environmental processes do not recognize the
political boundaries dividing the areas (Figure 1). Also, RBNERR and TTINWR
managers have recognized their inherent connections and have formed a strong
partnership in the management of the area.

Visitors to Rookery Bay were interviewed at many popular access points to target
as many types of users as possible. From September 2000 to March 2002, a total of 312
visitors were interviewed. Researchers contacted the first 157 study participants at public
boat ramps, throughout Naples and Marco Island, which provided access to RBNERR.
Researchers conducted the entire interview on-site for these respondents. To ensure
researchers interviewed tourists to the RBNERR area, researchers targeted boat rental
companies and surveyed 155 RBNERR visitors. To save time on-site, these interviews
were divided into a short on-site interview and a longer mail-back questionnaire (46.5%
response rate).
The study area was divided into ten recreation zones in order to assess where
visitors traveled, where they spent the most time, and what they considered to be their
most favorite areas (Figure 2). Also, understanding where visitors traveled throughout
the study area, but other information (e.g., perception of impacts, desires for
management, and participation in activities) into a practical context.
Key Findings
Socio-demographic Characteristics
Survey participants were mostly white males, between the ages of 26 to 55.
Most were married with children, and many were well educated.
· The household income of respondents was well distributed, however many
averaged above $96,000 per year.
· Over half were local to the Naples/Marco Island area, and more than three-
quarters were repeat visitors.
Trip Characteristics
· Visitors spent the most time in and around zones 4, 6, and 7 (Keewaydin/Marco
Island area).
· The most common primary activities included fishing, boating, and wildlife
viewing or sightseeing.
· Visitors were motivated to come to Rookery Bay to reduce tension, enjoy nature,
for achievement or stimulation, and to spend time with their family.

Additional research is needed to assess the acceptability of the proposed
management strategies and to evaluate the success of suggested communication
campaigns. As the population in Collier County grows, steps will need to be taken to
minimize the social and ecological impacts associated with high recreational use,
consequently conflicts between residents and non-residents will be an issue of furore
concern. Getting input from community stakeholders and organizing those citizens
concerned with the conservation of local natural resources will continue to be a vital
component of any future initiative.
Ultimately all ecological impacts can affect the recreational experience of visitors
to Rookery Bay. Solving problems, which harm the delicate balance of the southwest
Florida ecosystem, will take a comprehensive, countywide effort, an effort, which
includes citizen involvement, communication strategies, and continued monitoring of
ecological impacts.

Coastal Management: Naples Bay Example
Like many urbanized bays, Naples Bay represents a highly altered system. Naples Bay
and its watershed are drastically different from their historical state as a result of the land
use changes that have occurred during the development of Collier County. Many of these
changes that have occurred in estuarine areas have been intentionally implemented in
order to achieve or maintain an important outcome (e.g., flood control, water supply,
transportation needs). These characteristics can be found in many developed coastal
areas of Florida:
· Alteration of historic flow ways: To maintain flood control in the wet season
and water supplies during the dry season, sheet flow is now blocked and
channeled through managed canal systems. Often, these systems connect or
divert historic drainage basins, effectively altering the size of the watershed
(Naples Bay, for example, now drains approximately ten times more land area
than it historically did)
· Loss of wetland function: Canals are intentionally designed to rapidly convey
floodwaters to the estuaries. As a result, they do not filter storm water or buffer
large freshwater pulses as effectively as the wetlands that historically transported
slow moving and widely dispersed sheetflow.
· Increased impervious surface: Roads, parking lots, and buildings allow much
less stormwater to infiltrate into the ground. Instead, this water is diverted
directly into storm drains and then quickly to canals or coastal waters, and can
carry large amounts of sediment, pollutants and nutrients directly to the bay.
Furthermore, this diversion decreases groundwater and aquifer recharge.
· Increasing turbidity: Increased sediment from erosion and stormwater runoff
clouds the water and decreases light available for seagrass growth. High sediment
loads can also impact bottom plants and animals as it settles out of the water. In
addition, vessel traffic continually resuspends these sediments from the shallow
bottom.
· Shoreline alteration: To provide waterfront access and stabilize erosion on
property lines, the shoreline has been physically altered and hardened in many
locations. This alteration often results in a loss of mangroves and other fringing
habitats, along with the functions they perform.
As stated above, these changes were made to accomplish certain goals. However, with
increased understanding of the relationship between ecological systems and community
needs, and with new technology, it is often possible to achieve these goals with less
impact, or even improved benefit, to the natural systems. This increased understanding
can be applied to new developments, redevelopments, or to guide dedicated restoration
efforts that aim to mitigate as much loss of ecosystem function as possible, while still
maintaining the infrastructure needs of the community. As a result, Naples Bay, and
other urbanized bays like it, are wonderful opportunities for collaboration and shared
stewardship across disciplines and district lines in order to achieve constructive
outcomes.

Findings of the Naples Bay Group
Presented by Dr. Mike Bauer, South Florida Water Management District
Naples Bay is a relatively narrow and shallow estuary ranging in width from 100 to 1500
feet; and in depth from 1 to 23 feet. As stated in the previous section, it has been altered
in many ways as a result of recent urbanization. Specifically:
· The historic watershed area was predominately comprised of swamps, marshes
and sloughs that recharged the aquifer and supported native plants and animals.
This gradually changed from those natural conditions, to agriculture, and then to
urban land uses.
· The Bay once drained about 10 square miles, but it's now the receiving body from
approximately 120 square miles due to the construction of the Golden Gate Canal
system.
· The natural water inlets like the Gordon River, Rock Creek, and Haldeman Creek
have been altered by urban infrastructure that has virtually eliminated the historic
flowways to the Bay and impacted both water and biology.
In late 2002, an unofficial group of people got together to discuss the Bay's problems.
This group included staff from city, state, and local government, environmental groups,
and the private sector. We found that, over the past 25 years, there have been several
studies of Naples Bay that have produced recommendations for improved management.
In 1979, The Conservancy of Southwest Florida issued a report entitled the "Naples Bay
Study," which made the following recommendations
,, Slow the flood of fresh water in the summer by:
o Improving the weir system,
o Putting earth plugs in the Golden Gate canals, and
o Re-flooding all of Golden Gate.
· Prevent bacteria from accumulating in the water column by building a better
sewage treatment system.
· Control the speed of watercraft
· Enforce shore-based pollution problems
· Improve stormwater runoff by:
o Plugging all storm sewers and directing water to a sewage plant,
o Allowing only licensed operators to carry out lawn treatments, and
o Removing debris from residential canals and correcting their depth.
In 1988, The Naples Area Chamber of Commerce established a Naples Bay Task Force,
which among its recommendations recommended the formation of a Bay Management
Organization. This organization was roughly parallel to the Metropolitan Planning
Organization, and made up of County Commissioners, City Council members, with a
citizen advisory committee and a technical advisory committee. The Bay Management
Organization recommended:
· Carrying out a hydrographic study of Naples Bay (how much water goes where),
31
promoting informed decisions
Establishing a stormwater utility, a funding mechanism for building facilities to
control stormwater
· Expanding the dredging and maintenance of residential canals,
· Replacing vertical seawalls with rip rap,
· Developing a Golden Gate Basin Management Plan
In 1997, the Naples City Council established a Naples Bay Project Committee, which
recommended:
· Marine vessels be better controlled
· Water quality be improved by
o removing debris,
o aerating canals,
o preparing a bathymetric chart of the Bay,
o restoring mangroves,
o creating artificial habitats in the Bay,
o connecting dead end canals,
o implementing a stormwater master plan, and
o educating citizens
As a result of these studies, several of these recommendations have actually been carried
out, including:
The Golden Gate discharge rate has been slowed by improvements in the canal
system
· The wastewater treatment plant has been upgraded to tertiary treatment
capabilities
o Former package and septic systems have been hooked up to the central
sewer system
o All septic tanks in Naples have been eliminated.
· Stormwater management is ongoing
· Depth changes in some canals have been corrected
· Vessel speed controls are in place.
However, there are still continuing problems that are negatively impacting the health of
Naples Bay. The recent informal Naples Bay group, after reviewing these studies,
identified three major remaining problems in Naples Bay:
· Stratification of the water column in the Bay and in canals is affecting oxygen
levels, salinity, and the movement of food for aquatic organisms.
· Stormwater runoffis still negatively impacting the Bay, and
· Loss of estuarine habitats, such as mangroves, seagrasses and oyster reefs, has
occurred due to changes in the shoreline.
A short time after this group began meeting, we learned that the South Florida Water
Management District had identified a number of projects designed to address these
problems. The District has approached the Florida Legislature for the funding necessary

to carry them out. The WMD came to our group and explained their projects to us, which
included:
Developing stormwater management plans for the Gordon River Basin and the
Gateway Triangle,
· Stormwater improvements to the existing Lely area drainage system,
· Modifications of Golden Gate Canal Weir #2 and 1-75 Canal Weir #1,
· Mapping and hydrodynamic modeling of Naples Bay, and
· Restoring submerged aquatic vegetation
They then asked our group to rank the projects in order of importance to the Bay. The
group ranked them the following order:
1. Developing a bathymetric map and hydrologic model for Naples Bay (what water
goes where) to be used as a management tool. This can also help identify areas
most impacted by fresh/salt water stratification.
2. Developing the Gordon River Basin Stormwater Management Master Plan
3. Modification of Golden Gate Canal Weir # 2.
4. Modification of 1-75 Canal Weir #1.
5. Document the historic distribution of habitats (SAV, oyster reefs, mangroves)
prior to restoration efforts.
6. Gateway Triangle Stormwater Management Plan.
To accomplish these goals, the group recommends the establishment of a formal
implementation team. This group should be comprised of individuals capable of moving
forward and acting on the restoration initiatives. The Naples Bay Group recommends
that this formal implementation team should be comprised of core group of individuals
that represent:
· Collier County Commission
· City Council of Naples
· Collier County and City of Naples Natural Resources Departments
· SFWMD Big Cypress Basin
· Rookery Bay NERR
· Non-profit
· Private industry
· Citizens

Coastal Management Tools
Presented by Gary Lytton
Environmental Administrator, Rookery Bay Reserve
There is a suite of management strategies or tools available to local governments to help
address the challenges of coastal management in Collier County:
Research and Monitoring: Establishing and sustaining long-term monitoring of
changing coastal conditions, combined with data analysis, can yield important
information to managers and decision-makers. Monitoring can provide an "early warning
system" that allows managers to address water quality problems before they become a
crisis. Monitoring results are also used to direct restoration and stormwater management
efforts. Basic and applied research is essential for increasing knowledge and
understanding of coastal processes and the changing relationship of humans to the coastal
environment. Applied research directed to specific issues can result in solutions to
coastal problems, such as minimizing the effects of mosquito aerial spraying on non-
target species, and reestablishing natural fresh water flow regimes to estuaries.
Land Use Planning and Mapping: Strategic planning for sustainable use of
coastal resources is an important tool that enhances protection of critical habitats and
helps to ensure a sustainable economy. As the county population increases, Naples,
Marco Island, and Everglades City are transitioning to the redevelopment of coastal
communities. Planning for restoration and sustaining fresh water flow ways, enhancing
stormwater treatment and management, and allocating sufficient fresh water to estuaries
are examples of coastal management strategies designed to sustain a healthy coast.
Access to recent technological advances in Geographic Information Systems (GIS) can
greatly enhance planning efforts through the use of high resolution satellite and aerial
imagery combined with analysis of spatial data.
Restoring Altered Hydrology and Wetlands: Restoration projects designed to
restore impacted coastal wetland habitats (e.g. mangroves) have bccn successfully
completed at a number of coastal sites in Collier County. More recently, restoration
projects designed to restore altered fresh water or tidal flows (e.g. bridges, culverts,
"geoweb," and removal of roads) have been conducted. The planned restoration of thc
Southern Golden Gate Estates is an example of a large-scale watershed restoration
designed to restore altered flows to the Ten Thousand Islands estuary.
Education and Training: Increased community awareness of coastal resources
and issues is a powerful management strategy that promotes coastal stewardship in the
private and public sector. Residents are key decisions-makers on issues ranging from
land use to resource protection. Professionals, including elected officials, land use
planners, developers, agricultural interests, environmental regulatory officials, and
coastal managers are decision-makers with profound influence on the coast. Education
and training designed to provide accurate, science-based information can help promote
more informed decisions effecting coastal resources.

Promoting informed decisions in Southwest Florida through science-based training for the professional c~mmunitF
Since the tare 1980's', Southwest Florida has been one of the nation's fastest devetoping regions.
Such unprecedented growth has. chattenged communities to seek ways to improve decisions about
[and use, environmentat regutations, water resources and coastar management. The professionats
that make these decisions include government, academic, nonprofit, agriculture, devetopment and
real estate, marine trades, and many others. This targe audience of coastar poticy- and decis!on-
makers needs accurate science-based information about coastar systems on which to base. their
decisions. Through the Coastar Training Program (CTP) RBNERR can buitd on considerabte expert-
ence and offer more focused training opportunities to these targeted audiences.
The Coastar Training Program has three key objectives:
· Provide the best avaitable science-based information,
toots, and techniques required by individuals and groups
that are making important decisions regaFding coastar
resources
· Increase regionat networking and cot[aboration across
commUnity sectors invotved with coastar management
issues
· Increase understanding of the environmentat, social -
and economic consequences of human activity with the
coastar tandscape
RBNERR began a series of bimonthty Coastar Zone Management
workshops in 1989 to hetp improve decisions about coastal
resources in Southwest Ftorida. The workshops target coastal
management professionats, and include topics, ranging from water-'
shed restoration and invasive plant control to marine mamma[
recovery and oit spit[ response. The workshops proved to bca
successful forum for training and networking coastar professionats,
and were eventually adapted for use as a mode[ for five other
sites in Florida as wet[ as the 25 Nationat Estuarine Research
Reserves in the U.S. The Coastal Training Program represents the
next step in enhancing training opportunities across the country.
The Rookery Bay National Estuarine Research Reserve is managed by the Florida Department
of Environmental Protection in cooperation with the National Oceanic and AtmosPheric
Administration. The Reserve's mission is to provide a basis for informed coast~! decisions
........ through research, education, and stewardship. For more information, contact (239) 417-6310

ROOKERY BAY RESERVE BOUNDARY APPROVED BY NOAA
NAPLES -Rookery Bay National Estuarine Research Reserve has received notification from the
National Oceanic and Atmospheric Administration's Office of Ocean and Coastal Resource
Management that the five-year management plan and boundary expansion has been approved.
The federal approval of the 110,000-acre boundary for the Reserve comes following an extensive
review and public planning process that began in 2000. All lands included in the federally
approved Reserve boundary are state-owned or under lease to the state. The designation
provides federal resources and support for research, restoration, education and training. The
boundary approval also identifies the expanded area including the Ten Thousand Islands as an
estuary of national significance. Approval by NOAA does not bring additional federal rules or
regulations, as the National Estuarine Research Reserve System depends on existing state
authority to manage and protect reserves.
Public review and participation involved three workshops and review by a multi-agency council.
The Governor and Cabinet approved the boundary proposal in October 2001.
The mission of the Rookery Bay Reserve is to provide a basis for informed coastal stewardship
through research and education. The management plan identifies management goals that address
priority resource management issues, as well as specific strategies to accomplish these goals.
The plan outlines an adaptive management strategy using a science-based approach to
stewardship.
One of 25 nationally designated National Estuarine Research Reserves, the Rookery Bay
Reserve is managed by the Florida Department of Environmental Protection in cooperation with
the National Oceanic Atmospheric Administration and protects one of the few remaining
relatively undisturbed mangrove estuaries in the nation.
