Executive Summary
In 2005, the State of Florida completed the Florida Comprehensive Wildlife Conservation
Strategy (FWC, 2005). The Florida CWCS identifies and rates threats to the state’s
terrestrial, freshwater and marine habitats and identifies and rates strategies to abate the
top rated threats. While this is a highly valuable resource that will help guide the actions
of resource managers and other stakeholders to protect these resources over the next
several years, it lacks site specific advice for abating threats to the state’s environmental
resources. The Big Bend Conservation Action Planning process described in this
document follows up on the CWCS effort by providing a narrower focus on a specific
area of Florida. The Big Bend Conservation Action Plan (CAP) focuses on the marine
and estuarine resources of the Big Bend area of Florida. For purposes of this effort, the
Big Bend CAP planning area is defined as extending from Lighthouse Point (coast south
of Tallahassee) at its north end west and south to Anclote Key (just north of Clearwater,
Florida near Tampa Bay) at its southern end. The inland boundary of the project area is
the influence of saltwater as defined by the National Wetlands Inventory classifications
for marine and estuarine wetlands. The offshore boundary extends to the state waters
boundary which, on the Gulf Coast is 9 nautical miles from the shoreline.
To complete the Big Bend CAP, we have utilized a process developed and refined by The
Nature Conservancy over the last 10 years called Conservation by Design. Site
conservation through the development and implementation of Conservation Action Plans
has been carried out by the Conservancy and its partners around the globe. Some key
features of Conservation Action Plans (CAPs) are identification of conservation targets to
represent the ecosystem under consideration, identification of key threats to these
conservation targets, development of strategies to abate these key threats and methods for
measuring the success of implemented strategies. The strategies are to be reviewed
periodically and adapted as necessary depending on what the measures of success
indicate.
Over the last year and a half, we have held a series of meetings with Big Bend region and
statewide marine and estuarine resource experts and stakeholders to guide resource
characterization, threat assessment and strategy development. In addition, we have
corresponded with some of these same experts to advise us on the development of the
viability assessment component of the CAP. This effort builds on the numerous ongoing
conservation and management efforts that have been implemented in the Big Bend region
for a number of years by utilizing the information that has been gleaned about the
resources and their condition. A key value of this effort is to bring together in one place a
comprehensive compendium of actions that will be needed to ensure protection of area
resources for the use and enjoyment of future generations. The review of ongoing actions
to abate threats and measure success contained in this document also points out some
gaps in management actions and assessment that should be filled in order to ensure the
future health of area resources.
vi
In this report, we provide background on the key steps of the CAP process and detail the
results from the meetings and other analyses. The keys steps of the CAP process and our
findings are as follows:
Identify conservation targets to represent all area resources
We selected the following conservation targets to represent the marine and estuarine
ecological systems of the Big Bend region of Florida:
• Submerged Aquatic Vegetation
• Salt Marsh - Tide Flat Complex
• Oyster Reef
• Live Bottom Community
• Florida Manatee
• Fish Community
• Diadromous Fish; and
• Bay Scallops
Assess viability of the selected conservation targets;
We assessed the viability of each conservation target by examining three broad measures
of resource health: size, condition and landscape context. We identified specific attributes
to measure health and rated the health status of each conservation target by reviewing the
relevant scientific literature and survey results and by consulting with state and regional
resource experts. In summary, we found that individual conservation target health ranged
from fair to very good and that overall, the ecological health of the area could be
considered good.

vii
Identify and rank the critical threats to the conservation targets
We evaluated and rated approximately twenty potential threats to marine and estuarine
resources for each conservation target. When synthesized for all conservation targets in
the planning area, we identified the following nine very high or high rated threats:
harmful algal blooms, coastal development, fishing gear impacts, utility corridors, dam
presence, nutrient loads, dredging, inadequate stormwater management and incompatible
fishing pressure.
Develop strategies to abate the critical threats, detailed action steps and a work plan
At an expert workshop, we developed strategies to abate the top-rated threats and rated
each of these strategies. The ranking of the threats and strategies provides a tool for
resource managers and other stakeholders to focus on top priority threats and strategies in
the planning area. Below are the strategies that received a high or very high rating.
Top Rated Strategies to Abate Harmful Algal Blooms (includes toxic and harmful,
non-toxic blooms & black water events; goes beyond red tide)
Objective A: The conditions necessary to trigger HABs are understood and management
resulting in arrested HAB development is in place by 2016.
• Using data/information from existing water quality monitoring programs in the Big
Bend (FWC and Project Coast, UF, Tom Frazer), define as best we can what the
natural background levels of nutrients are for the area (current, baseline and/or
historic).
• Push for congressional support (i.e., funding) to address HABs now "while the iron is
hot".
• Conduct/support research that builds on existing knowledge to identify the cofactors
that trigger HABs.
• Create incentives for the placement of advanced septic systems. These could be tax
incentives. Water management districts and local governments may be the
appropriate leads for this action.
Objective B: Understanding of the dynamics and movement of HABs along the Big Bend
Coast allows prediction and early warning about HAB impacts to potentially impacted
communities by 2016.
• Purchase and deploy an adequate network of in situ samplers.
Top Rated Strategies to Abate/Reduce Impacts of Coastal Development
Objective A: By 2016, at least 90% of Big Bend planning area shorelines remain in a
natural condition (i.e., unhardened) so as to allow for natural processes to proceed
uninhibited.
• Modify federal/state flood insurance programs in coastal high hazard regions to
strictly control payment of repeat claims in areas subject to frequent flood events. For
example, after a certain amount of loss, the property becomes public or the owner can
rebuild at their own cost (for example, pay to rebuild once).
• Implement an education program to promote soft shoreline alternatives to hardened
shoreline
• Ensure adherence with the CCCL rules and shift the coastal construction control line
landward
viii
Objective B: Allow the migration of marine/estuarine habitats inland (i.e., upslope) as sea
level progresses by purchasing 50% of unprotected lands within 1 mile of the 2006
shoreline by 2016.
• Purchase more coastal conservation lands and easements
• Develop a mechanism to improve communication between developers and the
conservation community to circumvent problems upfront.
Top Rated Strategies to Abate Fishing Gear Impacts
Objective A: By 2016, Fishing gear improvements are developed and implemented that
result in minimal irreparable damage to marine and estuarine habitats from fishing
activities.
• Develop gears less harmful to bottom habitat for harvesting bait shrimp as an
alternative to roller frames.
• Conduct a broad-scale characterization of benthic communities and associated
habitat.
• Consider rotational closure of bottom trawling for the most sensitive areas.
• Develop aquaculture production for bait shrimp and other types of bait.
Top Rated Strategies to Abate the Threat of Utility Corridors
Objective A: Sensitive living resources in the Big Bend planning area are protected from
degradation by ensuring that all utility corridors approved for the planning area are sited
in the least vulnerable areas, effective 2006.
• Ensure that the least environmentally sensitive locations are selected for placement of
utility corridors, especially with respect to bay scallops. Consider co-location of
utilities when feasible.
• Ensure that the proper safeguards are employed to minimize secondary impacts
associated with utility corridor siting.
Top Rated Strategies to Abate the Presence of Dams
Objective A: Restore self-sustaining populations of target diadromous fishes, by
reconnecting upstream and downstream habitats across the dam at Lake Talquin
(Ochlocknee River) by 2016.
• Develop/implement fish passage technologies
Top Rated Strategies to Abate Nutrient Loads
Objective A: By 2011, determine natural background levels of nutrients in Big Bend
Region coastal waters, quantify nutrients loads especially from river sources such as the
Suwannee and develop nutrient targets for sustaining project area marine and estuarine
systems as viable and healthy.
• Determine natural background levels of nutrients in the Big Bend area. Use this
information to define nutrient targets. The FWC and water management districts
(Project Coast) may already have some of this information.
Objective B: By 2016, implement nutrient reduction programs such as best management
practices (BMPs) aimed at a minimum of achieving nutrient targets in the Big Bend
ix
Region. Focus on the most sensitive areas first. May use the results of the Conservancy's
Site Assessment to identify the most sensitive areas.
• Support continued and expanded implementation of BMPs in Suwannee Basin (Water
management districts may have data on dairy & chicken farms BMP implementation).
• Implement nutrient reduction techniques in sensitive areas or draining to sensitive
areas. For example, require septic systems that treat nutrients more effectively than
the status quo for all new development. For existing systems, require upgraded
system upon the need to replace it. This action will likely include new regulations
and/or code.
• Support the Water management districts ongoing work to retrofit existing stormwater
treatment areas identified to be problematic. Develop improved stormwater treatment
systems to reduce invasive species that thrive on high nutrients.
• Encourage the Water management districts and local governments to champion the
creation of incentives for placement of advanced septic systems (could be tax
incentives).
Top Rated Strategies to Abate Dredging Impacts
Objective A: From now into the future, maintain the ecological integrity of Big Bend
Area seagrass beds and salt marshes by preventing the unnecessary dredging of these
systems especially in designated managed areas such as the state's Aquatic Preserves.
• Prevent the dredging of new boating channels by effectively maintaining existing
dredged channels. Establish a rule that prevents new channels from being dredged in
managed areas or through high quality benthic communities.
Objective B: Beginning now, minimize the adverse impacts of dredge disposal by
identifying the least ecologically damaging and/or most ecologically beneficial methods
for dredge disposal.
• Create and implement effective uses for dredged spoils. For example, enhance
existing bird nesting sites.
Top Rated Strategies to Abate Incompatible Stormwater Management
Objective A: By 2016, accelerate WMD and local government efforts to retrofit
stormwater treatment systems throughout the planning area.
• Support the Water management districts ongoing work to retrofit existing stormwater
treatment areas identified to be problematic.
Top Rated Strategies to Abate Incompatible Fishing Pressure
Objective A: By 2016, stocks of all harvested species in the planning area are effectively
managed so as to ensure viable and sustainable populations into the future.
• Improve species specific management by evaluating/re-evaluating minimum size &
slot limits, seasons, bag limits, rotational harvest and closed areas.
• Improve protection at existing managed areas including more support for marine
enforcement.
• Pursue enhancement and restoration strategies for redfish, oysters, bay scallops and
other species as may be determined in the future.
x
Establish measures for evaluating the success of the strategies
Strategies, once implemented, must be evaluated periodically to determine if they have
been successful. In the final section of this report, we recommend measures to monitor
success for each conservation target. Some of these measures are already being
monitored comprehensively by resource agencies or institutions. Others are being
monitored, but only in certain locations or infrequently. Some of these factors are not
currently measured.
The development of the Big Bend CAP and preparation of this document are but first
steps in the conservation process. Continued implementation of the already ongoing
management and conservation efforts as well as implementation of the additional efforts
recommended in this document will be required to ensure the future health of Big Bend
area marine and estuarine resources.

I. Introduction
The Big Bend Coast is distinctive in Florida in that it is a low energy coastline with vast salt
marshes and seagrass beds among other important ecological communities. This coast remains
the least developed coastal region in Florida, but there is accelerating pressure to grow. This
combination of vast resources and relatively undeveloped coastline is a key reason the ecological
resources in this area remain so important. The vast seagrass beds in this region undoubtedly
make a significant contribution to Gulf of Mexico fish and invertebrate (e.g., shrimp) production.
This Conservation Action Planning process for the Big Bend Region of Florida follows and
builds on the Comprehensive Wildlife Conservation Strategy developed last year for the state of
Florida (FWC, 2005). The Strategy summarized conservation threats for all of the state’s major
habitat types and provided a prioritized list of actions to abate the identified threats, among other
things. With this effort, we have focused in on marine and estuarine resources of one area, the
Big Bend Region, to provide a more detailed look at conservation challenges and develop more
region specific actions to abate the identified threats. For this effort, we have used a process
developed and refined by The Nature Conservancy to develop a Conservation Action Plan.
Conservation Action Plans have been developed and implemented by the Conservancy and its
partners around the globe. Some key features of Conservation Action Plans (CAPs) are
identification of key threats to area resources, development of strategies to abate these key
threats and methods for measuring the success of implemented strategies. The strategies are to be
reviewed periodically and adapted as necessary depending on what the measures of success
indicate.
Over the last year and a half, we have held a number of meetings with Big Bend region and
statewide marine and estuarine resource experts and stakeholders to guide resource
characterization, threat assessment and strategy development. In addition, we have corresponded
with some of these same experts to advise us on the development of the viability assessment
component of the CAP. This effort builds on the numerous ongoing conservation and
management efforts that have been implemented in the Big Bend region for a number of years by
utilizing the information that has been gleaned about the resources and their condition. A key
value of this effort is to bring together in one place a comprehensive compendium of actions that
will be needed to ensure protection of area resources for the use and enjoyment of future
generations. The review of ongoing actions to abate threats and measure success contained in
this document also points out some gaps in management actions and assessment that should be
filled in order to ensure the future health of area resources.
In the following sections, we provide background on the key steps of the CAP process and detail
the results from the meetings and other analyses. The keys steps described in this document are
as follows:
• Define project area and identify conservation targets to represent all area resources;
• Assess viability of the selected conservation targets;
• Identify and rank the critical threats to the conservation targets;
• Develop strategies to abate the critical threats, detailed action steps and a work plan; and
• Establish measures for evaluating the success of the strategies;

The development of this CAP and preparation of this document are but first steps in the
conservation process. Continued implementation of the already ongoing management and
conservation efforts as well as implementation of the additional efforts recommended in this
document will be required to ensure the future health of Big Bend area marine and estuarine
resources.

II. Project Area and Conservation Targets Defined
In this step of the Conservation Action Planning process, the project team defined the project
area and the conservation targets. Conservation targets are the natural systems (aka habitat types)
and specific species that were selected as representative of the overall biodiversity of the project
area. In this planning process, we limited ourselves to eight conservation targets.
Project Area
The project area is illustrated in Figure 1 and extends from Lighthouse Point (coast south of
Tallahassee) at its north end west and south to Anclote Key (just north of Clearwater, Florida
near Tampa Bay) at its southern end. The inland boundary of the project area is the influence of
saltwater as defined by the National Wetlands Inventory classifications for marine and estuarine
wetlands. The offshore boundary extends to the state waters boundary which on the Gulf Coast is
9 nautical miles from the shoreline.
Conservation Targets Selected for the Big Bend Conservation Action Plan
The following conservation targets were selected by the project team as being representative of
the biodiversity of the entire project area:
• Submerged Aquatic Vegetation
• Salt Marsh - Tide Flat Complex
• Oyster Reef
• Live Bottom Community
• Florida Manatee
• Fish Community
• Diadromous Fish
• Bay Scallops
For a complete list of nested targets within each habitat type conservation target see the Florida’s
Comprehensive Wildlife Conservation Strategy (FWC, 2005).
Where geospatial information was available for a conservation target, it is displayed in Figures 2
– 10 which are grouped at the end of this section (pages 8-14). Additional information on the
Live Bottom Community, Fish Community and Diadromous Fish conservation targets is
included below.
Live Bottom Community Of all the conservation targets selected for this conservation action plan, live bottom community
along Florida’s Gulf Coast is the least well known, especially within state waters. The U.S.
Department of the Interior, Minerals Management Service has defined two types of live bottom
community in the Eastern Gulf of Mexico as follows:
• “Live bottoms (low relief features) means seagrass communities, areas that contain biological
assemblages consisting of sessile invertebrates living upon and attached to naturally
occurring hard or rocky formations with rough, broken, or smooth topography; and areas
4
Figure 1. Big Bend Conservation Plan, Project Area
•

where a hard substrate and vertical relief may favor the accumulation of turtles, fishes, or
other fauna.”
• “Live bottoms (pinnacle trend features) means seagrass communities, areas that contain
biological assemblages consisting of sessile invertebrates living upon and attached to
naturally occurring hard or rocky formations with rough, broken, or smooth topography; and
areas where hard or rocky substrate and vertical relief may favor the accumulation of turtles,
fishes or other fauna.” (USDOI, MMS, 2004)
For purposes of this document, we are not including seagrass beds in the definition of live
bottom community because we place seagrass in a category of its own. Figure 6 below illustrates
the locations where live bottom may be present in the Eastern Gulf of Mexico off the Florida
Coast. Low relief live bottom is depicted as possibly present over a large portion of this area.
Pinnacle trend live bottom is not depicted on this map as occurring off the Florida Gulf Coast.
An attachment to the above referenced document further describes the biological assemblages
associated with live bottom, low relief communities as those “consisting of sessile invertebrates
as sea fans, sea whips, hydroids, anemones, ascidians, sponges, bryozoans, or corals living upon
and attached to naturally occurring hard or rocky formations with rough, broken, or smooth
topography.”
Fish Community The Florida Fish and Wildlife Conservation Commission, Fish and Wildlife Research Institute
tracks 134 fish and invertebrate species or groups in state waters and prepares annual reports
detailing their status (FWC/FWRI, 2005). The species and species groups tracked are listed in
Table 1. Of these, 132 are considered to be present on the Florida Gulf Coast. Information
contained in these reports comes from commercial and recreational harvest data as well as
fisheries independent monitoring. Species and species groups tracked through this program
include the following: greater amberjack, ballyhoo, bluefish, bonefish, catfish, cobia, Atlantic
croaker, dolphin, black drum, red drum, flounders, gag grouper, red grouper, grunts, Atlantic
thread herring, hogfish, crevalle jack, kingfish (whitings), ladyfish, king mackerel, Spanish
mackerel, menhaden, striped mullet, permit, pinfish, Florida pompano, Spanish sardine, spotted
seatrout, sheepshead, gray snapper, lane snapper, red snapper, vermilion snapper, yellowtail
snapper, common snook, spot, tarpon, triggerfish, tripletail hard clams, blue crabs, stone crabs,
spiny lobsters, oysters, calico scallops, penaeid shrimp, and rock shrimp. Other fish and
invertebrates included in this general category of fish community can be found in Florida’s
Comprehensive Wildlife Conservation Strategy (FWC, 2005).
Diadromous Fish Diadromous fish use both marine and freshwater habitats during portions of their life cycle.
Species fitting this description may be anadromous or catadromous. Anadromous species spawn
in rivers, and then migrate to sea to spend most of their life. Catadromous species spawn at sea,
but spend most of their lives in lakes, ponds and rivers. Several diadromous species utilize the
fresh, brackish and saltwaters of the Big Bend Region of Florida including federally listed and
candidate species such as the Gulf sturgeon (Acipenser oxyrinchus desotoi) and Alabama shad
(Alosa alabamae), species under consideration for listing such as the American eel (Anguilla
rostrata) and other more common species such as the common snook (Centropomus
6
undecimalis). Some of these species are also included in the description of fish community
above.

Contribution of Conservation Targets to Statewide Total The seagrass and salt marsh habitats in the Big Bend region of Florida make a substantial
contribution to the statewide total of these resources with seagrass contributing more than 27%
of the statewide total and salt marsh contributing over 31% of the statewide total (Table 2).
Seagrass in the Big Bend project area may actually make a greater contribution to the statewide
total as the seaward extent of seagrasses in some portions of the project area have not been fully
assessed (Matson, 2005).

III. Conservation Target Viability Assessment
The purpose of the conservation target viability assessment is to identify the most effective
methods for measuring the health of each conservation target in its current state as well as over
time. This step in the CAP process also helps resource managers and conservation practitioners
identify which conservation targets are most in need of immediate attention. Viability measures
in the following categories were considered for each conservation target: landscape context, size
and condition. To complete the viability assessment for each conservation target, we used
literature reviews and expert judgment to assign poor, fair, good and very good viability ratings
for each target attribute. For some conservation targets, copious amounts of information and
data derived from research and assessment are readily available. For other conservation targets,

The threats rated very high and high for the Big Bend CAP planning area as a whole are
described in more detail below. Some threats that are important (i.e., rated very high or
high) for individual targets are not included in the descriptions below.
Harmful algal blooms (Very High rated Threat)
The Florida Fish and Wildlife Conservation Commission (FWC) has assembled
documentation on Harmful Algal Blooms (HABs) in Florida marine waters going back
160 years to 1844. FWC recently undertook an extensive review of the HAB data. What
it found was no clear trends indicating that the frequency and duration of HABs in
Florida marine waters had increased over the last several decades. Although a natural
phenomena, an increase in HAB events would be a major concern to ecological health of
marine and estuarine systems as HABs have been associated with fish, bird, marine
mammal, sea turtle, invertebrate and other wildlife mortalities (HAB Task Force
Technical Advisory Group, 1999). Approximately 50 species of toxic macroalgae have
been identified from Florida marine and estuarine waters. It is one species however,
Karenia brevis (formerly called Gymnodinium breve) the red tide organism that has by
far caused the most serious environmental harm, human health concerns and economic
impacts (HAB Task Force TAC, 1999). K. brevis is present in the Gulf of Mexico year
round, but its presence is considered a bloom when cell concentrations reach a critical
level (>100,000 cells per liter) documented to cause fish kills and manatee mortalities,
etc. The epicenter of K. brevis blooms has been defined as the Florida West Coast
between Tampa Bay and Charlotte Harbor from observation of these blooms in 22 of the
last 23 years. In the Big Bend area of Florida, K. brevis blooms have only been observed
in 5 to 10 of the last 23 years. Figure 11 illustrates K. brevis blooms from 1995 through
2004 (FWC-FWRI, 2006). No blooms during this period fell into the “high count”
category (>1 million cells per liter). Medium blooms (100,000 to 1 million cells per liter)
have occurred a few times since 1994 in the planning area, mostly in the west Apalachee
Bay area. Since 1996, FWC-FWRI has recorded the following observations on HABs
from the Big Bend CAP Planning Area:
• Summer 1998 blue-green algae/diatom bloom – From an FWC-FWRI report on
this bloom, it appears that it covered an area extending from Hernando Beach
north to the Suwannee River. A major loggerhead sponge mortality event was
determined to be caused by the bloom. The bloom appears to have been triggered
by increased rainfall from an El Nino event that resulted in increased nutrient
loads to nearshore waters. Nutrient sources were determined to be both natural
and anthropogenic.
• Summer – Fall, 2003 report by a sponge diver of yellow water, dying crabs and
bleaching coral offshore of Pasco and Hernando counties. FWC-FWRI staff
suspect red tide was the cause.
Although the Big Bend CAP Planning Area has not experienced the frequency or
duration of HABs that the Florida Gulf Coast south of the planning area has experienced,
these events do occur from time to time and it is clear from published reports that their
impacts would be potentially devastating to certain vulnerable marine and estuarine
resources. Surface circulation in the Big Bend region forms a large clockwise
27
(anticyclonic) gyre (Figure 12), which may form most consistently during the winter
months of October through March (He & Weisburg, 2002; Fitzhugh et al., 2005). This
seasonal gyre undoubtedly plays a role in how HABs are distributed in the project area.

Coastal Development (High Rated Threat)
Coastal development impacts and trends can be quantified by examining the following
parameters in the coastal watersheds that drain the Big bend CAP Planning Area:
population density, intactness of natural land cover, road density, percent impervious
surface and amount of hardened shoreline. Maps of these parameters for the relevant
coastal watersheds are provided below (Figures 16 - 20). Where possible, I also provide
quantitative information on the status of these threat measures.

*A large portion of HUC basin population is from the Pinellas Peninsula area and may
not substantially impact resources within the project area.
29
A study of tidal creeks along the South Carolina coast found that the ultimate stressor to
this ecosystem is human population density in a watershed and the impervious surface
that goes along with human presence (Holland et al., 2004). Holland et al. found that
impervious surface cover exceeding 10 – 20% adversely altered physical and chemical
characteristics of the environment and impervious surface cover exceeding 20 – 30%
adversely affected living resources. Overall, Holland et al. found impervious surface
cover in a watershed to be an integrative measure of the adverse human alterations to a
watershed.
None of the HUC basins draining to the planning area have impervious surface
percentages exceeding the threshold levels identified above (see Figure 17). However,
several of the smaller basins within HUC do exceed the stated thresholds. In particular, a
few sub-basins within the St. Mark’s River HUC basin exceed the threshold levels for
adverse impacts to physical/chemical characteristics and at least one exceeds the
threshold for adverse impacts to living resources as well. Some sub-basins of the Crystal
River to St. Pete HUC Basin also display percent impervious surface levels exceeding
adverse effects thresholds.

Fishing gear impacts (High Rated Threat)
In our conservation action planning process, fishing gear impacts was rated as a very high
threat to live bottom community and a medium threat to diadromous fish. Since the
conservation targets we evaluate are intended to collectively represent the entire marine
and estuarine system within the Big Bend Planning Area, it is appropriate to mention
other specific habitats or species that are also likely to be adversely impacted by fishing
gear.
Bottom trawling for shrimp is an important fishery in the Gulf of Mexico. While this
method of fishing is effective at catching shrimp, it has also been associated with a large
bycatch (Alverson et al., 1994) and implicated as causing harm to benthic habitats (NRC,
2002). Historical (pre-TED and BRD) bycatch in the Gulf of Mexico shrimp fishery was
estimated at 10:1 (10 kg of bycatch for every kg of shrimp caught) by Alverson et al.
(1993). On live bottom communities subject to bottom trawling, sea fans, stony corals
and sponges, etc. are removed and the substrate is flattened out (Nelson, 2005). Recovery
of these bottom habitats make take on the order of tens of years. No other current fishing
gear impacts were noted as significant in the project area.
Since the late 1980’s, numerous measures have been taken in Florida to reduce the
impacts resulting from the bottom trawling of shrimp:
• In 1989, the state of Florida established 5 seasonal shrimping closure zones in
Citrus and Hernando counties (see Figure 13 below);
• In 1990, the state required Turtle Excluder Devices (TEDs) on all trawling vessels
operating in state waters;
• In 1991, the state prohibited the use of trawl gear in an area offshore of Taylor
County;
• In 1992 (Wakulla through Pasco counties in all state waters), the state imposed
restrictions on the type of gear that shrimp vessels could use by requiring the use
of roller frames of a maximum size, by specifying a minimum size for net mesh
and by prohibiting more than 4 trawls to be pulled by any one vessel;
• In 1993, the state prohibited shrimping in approximately 500,000 acres of Big
Bend region inshore waters characterized by dense and patchy seagrass bottom
habitat and imposed seasonal restrictions on harvest for the rest of the area’s state
waters (no shrimping in July and August);
• In 1995, the state limited the size of trawls that could be used for shrimping; and
• In 1998, the state required the use of Bycatch Reduction Devices (BRDs) on all
otter trawls used for shrimping (Approved rule Summary, August 2006
http://marinefisheries.org/history/index.html)
Despite the numerous measures that have done much to protect marine and estuarine
resources in the Big Bend and other areas of the state, it appears that these measures may
not be sufficient to protect area living resources from irreparable harm. Recent scientific
studies suggest that shrimp trawling in the Gulf of Mexico is continuing to have a
significant adverse effect on sea turtles, small coastal elasmobranchs, various finfish
species and benthic habitats even though gear improvements such as TEDs and BRDs,
36
and seasonal closures in some areas, have been imposed (NRC, 2002; Nelson, 2005;
McDaniel et al., 2000; Shepard and Myers, 2005). Bycatch remains relatively high with
recent bycatch-to-shrimp ratios in the Gulf shrimp fishery estimated at 4.3:1 (Nelson,
2005). Although significant efforts have been taken by the state to protect certain types of
bottom habitats such as seagrass, other bottom habitats such as livebottom, where
shrimping continues to be allowed, remain vulnerable (See Figure 14). Even seagrass
areas may not be fully protected as Big Bend Seagrasses Aquatic Preserve staff members
have reported large rafts of seagrass following passes by shrimping vessels in the project
area (Blitch, 2006).
Texas, Louisiana and Florida have the largest shrimp fleets in the Gulf primarily working
waters from nearshore to 90 meters in depth (NRC, 2002). Along the Florida Gulf Coast,
however, the largest shrimp fleet is concentrated to the south of the Big Bend Planning
Area around the Florida Keys. The National Research Council (2002) study estimated
that on average Gulfwide, fished areas were trawled more than 2.5 times per year with
some localized areas swept 37 – 75 times annually. In the NRC report, shrimp trawling
statistical areas 6 and 7 represent the Big Bend region (Figure 15). Average shrimp
trawling days (24 hour) averaged 4,450 and 4,850, respectively, during the period 1998 –
1999. Each statistical region was further broken down by 5 fathom depth intervals to
provide some insight into particular areas of fishing focus. In area 6, effort was
concentrated in the 60 to 120 foot depth range. In area 7, fishing effort was distributed
throughout depths up to 120 feet. Trawling intensity at the levels recorded in the
planning area was considered moderate.

Utility corridors (High Rated Threat)
Construction, and possibly maintenance, of utility corridors fractionates the scallop
population by interfering with gamete and larval exchanges (Arnold, 2007). These
activities further disrupt interactions among local populations that have already been
significantly altered (Arnold et al., 1998).
Utility pipelines have been proposed in the vicinity of the planning area in recent years.
In early 2000, Buccaneer Gas Pipeline, L.L.C. proposed construction of a submarine gas
pipeline that would cross the Gulf of Mexico and come ashore near Anclote Key. The
Federal Energy Regulatory Commission granted approval for pipeline construction,
however, later in the year the plans were abandoned due to a business merger with
Gulfstream Natural Gas (St. Petersburg Times, 2000). At the time, Gulfstream was
proposing and ultimately built a trans-Gulf natural gas pipeline that comes ashore in the
southern Tampa Bay area after crossing 419 miles of submerged marine habitat. There
are no current submarine utility proposals in the study area.
40
Dam presence (High Rated Threat)
Two of the major rivers draining into the Big Bend CAP Planning Area have major dams,
the Ochlocknee River and the Withlacoochee River (Figure 21). “Major rivers” are
defined by the state as one of the state’s largest 50 rivers. “Major dams” are defined as 50
feet or more in height, or with a normal storage capacity of 5,000 acre-feet or more, or
with a maximum storage capacity of 25,000 acre-feet or more, based on information
contained in the U.S. Army Corps of Engineers National Inventory of Dams. The dam on
the Ochlocknee River is known as the Jackson Bluff Dam. Its purpose is to provide
hydroelectric power to nearby Tallahassee. The Withlacoochee River has two dams in it
southern basin. Both are close to the Town of Inglis. One’s stated purpose is for
navigation and the other’s is flood control. Dams of the type identified here can cause
adverse ecological effects by changing water flow patterns and by blocking the passage
of aquatic species across various areas of the river. Several aquatic species, such as
diadromous fish, native to coastal tidal rivers in the Big Bend area require transit into and
out of various portions of the rivers to complete life stages or to successfully feed. Gulf
sturgeon (Acipenser oxyrinchus desotoi) and Alabama shad (Alosa alabamae) historically
used the Ochlocknee River (FNAI) and Gulf sturgeon were commercially fished on the
Ochlocknee River until the 1970s (USFWS/GSMFC, 1995). Gulf sturgeon are still found
in the Suwannee and Ochlocknee Rivers (Wakeford, 2001). In the Big Bend region,
Alabama shad are still found in the Suwannee and Withlacoochee rivers (NatureServe,
2004; NOAA, 2006).

Nutrient Loads
Seagrass health is dependent on water quality. Declines in water quality can significantly
reduce seagrass coverage (FWC, 2003). Fourteen coastal rivers as well as groundwater
drain into the Big Bend area. Nutrient loads in some area rivers have increased steadily
over the last few decades. Seagrass beds in Suwannee Sound have disappeared and
upstream pulp mill operations have caused seagrass declines in the Fenholloway Estuary
(Carlson, 2004; FWC, 2003). Figure 21 illustrates the elevated nitrogen levels present in
the Suwannee River.

2000-2004.

Dredging (High Rated Threat)
Dredging is required to create and maintain navigation channels from marinas and docks
to deeper waters. The need and depth required for navigation channels depends on the
size and draft of boats that will utilize the navigation channel. The number of dredge
channels generally increases as an area becomes more developed and pressure increases
to provide more access to offshore areas. Dredging destroys submerged benthic habitats
and wetlands, increases turbidity and serves as barrier to the movement of some aquatic
species.
Inadequate Stormwater Management (High Rated Threat)
Stormwater management is closely related to coastal development. See the discussion
above on impervious surfaces under coastal development.
Incompatible fishing pressure (High Rated Threat)
The latest reported status and trends analysis on Florida’s harvested marine inshore and
nearshore fish and invertebrates (FWRI, 2005) found that only 1 species out of the 134
species tracked was in a declining rather than in a stable or increasing condition on the
Florida Gulf Coast. FWRI found crevalle jack (Caranx hippos) to be in a declining
condition from information collected on the species from recreational fisheries and
fisheries independent monitoring. Recreational harvest of the conservation target, bay
scallop (Argopecten irradians), is immensely popular in the project area and fishing
pressure was rated as a high threat.

V. Strategies to Abate the Highest Rated Threats
As part of the Conservation Action Plan (CAP) for the Big Bend region of Florida,
we developed and rated strategies to abate the top rated threats identified above in
Table 12 using a process developed by The Nature Conservancy as outlined in Low
(2003). Strategy rating criteria are provided in Appendix 3. In this section, we
identify the strategies and the rankings that were derived in an expert workshop
held in June 2005. Objectives that help to frame what the strategies are intended to
accomplish and the action steps that will be required to carry out each strategy are
also provided in this section. A workplan that provides a listing of all the action
steps plus details on a possible timeline is provided in Appendix 2 of this report.
Many of the strategies listed in this section will require the involvement of
agencies, stakeholder groups, research institutions and non-governmental
organizations to be most effectively carried out.

APPENDIX 1. Strategies for Some Threats Rated High or Very High for Individual
Conservation Targets
In general, as part of this Conservation Action Planning (CAP) process we focused our
strategy development efforts on the highest rated threats to the system as represented by
the conservation targets selected for the Big Bend CAP. With some additional time
available at the end of the Strategies Development Workshop, we developed strategies
for some of the threats that were rated high for individual conservation targets. These are
presented below.

Boating Impacts Ease Lead
Benefit Cost
Objective A: By 2011, all recreational boaters have
received advice/information on the sensitive nature of
seagrass and other marine/estuarine habitats in the Big
Bend planning area, understand how to avoid harming
these sensitive resources, and are motivated to do so.
1 Education - for example kiosks at marinas about the
location of sensitive resources.

2 Require individual boaters to have a license. L VH H H
Objective B: By 2016, all recreational boaters are taking
all reasonable actions to avoid harming benthic habitats in
the Big Bend planning area.
3 Require all boats to have a port-a-potty aboard. This could
be as simple as having a 5-gallon bucket with a lid aboard.
This is/could be a pilot project through the EPA Gulf of
Mexico Program.
M M M M
Objective C: By 2016, marinas and other
facilities/navigational aids that support recreational
boaters have the equipment and educational materials
available to support recreational boater efforts to take all
reasonable actions to avoid harming marine and estuarine
habitats and associated communities in the Big Bend
planning area.
4 Require pump out stations everywhere there is a marina. H H M M
5 Improve the channel marking system by utilizing better
channel markers and by having more complete coverage.

Objective D: By 2010, a regulatory and enforcement
scheme adequate to maintain sustainable seagrass of other
marine/estuarine habitats in the Big Bend planning area is
in place. See also related objective (and strategies) under
dredging impacts: Improve existing access points to avoid
the creation of new (prop scarring of seagrasses is
concentrated around access points).

enforcement if existing regulatory framework is
sufficient) to recover damages when injuries to
marine/estuarine habitat are caused by recreational
boating and use these damage recoveries to restore
impacted areas/habitats.

Benefit Cost
Objective A: By 2016, industrial discharges into the Fen
Holloway River are reduced sufficiently to allow recovery
of marine and estuarine waters and associated natural
communities in the vicinity of the Fen Holloway River
Estuary to a healthy and viable state with a seagrass
community comparable to pre-settlement conditions.
1 Repeal the class 5 designation for the Fen Holloway
River.

up technologies.
Appendix 2. Strategy Rating Criteria from Low (2003).
Feasibility
Ease of Implementation
Actions that are less complex have been successfully implemented previously, fit within the core competencies of the lead institution, and that appeal to key constituencies have a higher likelihood of success than other actions.
Very High Implementing the action is very straightforward; this type of action has been done often before and will appeal to key constituencies.
High Implementing the action is relatively straightforward, but not certain; this type of action has been done before and is likely to appeal to key constituencies.
Medium Implementing the action involves a fair number of complexities, hurdles and/or uncertainties; this type of action has rarely been done before; constituency support uncertain.
Low Implementing the action involves many complexities, hurdles and/or uncertainties; this type of action has never been done before and/or is unlikely to appeal to key constituencies.
Lead Individual / Institution
The availability of a lead individual/institution ("champion") with sufficient time, proven talent, relevant experience, and good institutional support to implement the action.
Very High A "champion" with sufficient time, proven talent, substantial relevant experience and institutional support is reasonably available and committed to lead implementation of the action.
High An individual/institution with sufficient time, promising talent, some relevant experience and institutional support is reasonably available and likely to be able to lead implementation of the action.
Medium An individual/institution with promising talent and sufficient time is reasonably available, but lacks relevant experience or institutional support.
Low No lead individual/institution currently available.

Benefit
Threat Abatement Benefit
The degree to which the proposed action, if successfully implemented, is likely to achieve the desired outcome(s). How much will this action, by itself, reduce the critical threat over the scope and scale it is degrading the habitat?
Very High The action, in itself, will abate the threat (source of stress). (Or will get 76-100% of the way there.)
High The action makes a substantial contribution towards abating the threat, but is not by itself sufficient. ( will get 51-75% of the way there)
Medium The action makes an important contribution towards abating the threat. (will get 26-50% of the way there)
Low The action makes a relatively small contribution towards abating the threat. (will get 1-25%of the way there)
Cost
Order of Magnitude $$
Total cost of implementing the action, including staff time -- in unrestricted or discretionary dollars (i.e. dollars that might be applied to other purposes) -- estimated for the time horizon of the action, but no longer than 10 years: (Total cost = One Time Cost + ((Annual Costs + Staff Time) * Number of Years))
Very High $10,000,000 or more
High $1,000,000 or more (up to $9,999,999)
Medium $100,000 or more (up to $999,999)
Low $10,000 or more (up to $99,999)
