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.

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.

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

Page 8: Big Bend CAP, Final Report - Public.MyFWC.com · Final Report Prepared by Laura Geselbracht The Nature Conservancy Florida Chapter March 2007 Acknowledgements The following individuals

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

Page 9: Big Bend CAP, Final Report - Public.MyFWC.com · Final Report Prepared by Laura Geselbracht The Nature Conservancy Florida Chapter March 2007 Acknowledgements The following individuals

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.

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;

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

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

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,

information and data are scarce. Viability assessments should be viewed as living documents that

should be adjusted as more complete information on targets become available. Table 3 below

summarizes the results of our viability assessment of the conservation targets selected to

represent biodiversity in the Big Bend CAP Planning Area. Tables 4 – 11 that follow present the

detailed viability assessments that we completed for each of the conservation targets and the

sources of information that we referenced to complete them.

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

(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 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,

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

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,

Page 46: Big Bend CAP, Final Report - Public.MyFWC.com · Final Report Prepared by Laura Geselbracht The Nature Conservancy Florida Chapter March 2007 Acknowledgements The following individuals

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.

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.

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.

Action Steps for Very High and High Rated Strategies

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.

Strategy NUTR, A-1: Determine natural background levels of nutrients in the Big Bend

area. Use this information to define nutrient targets. The FWC and WMDs (Project

Coast) may already have some of this information.

Action Steps:

a. Review existing data on natural background levels of nutrients in the Big Bend

Region and nutrient loads into area rivers;

b. Work with WMD, state and local government staff to develop nutrient targets for

defined Big Bend areas.

Objective B: By 2016, implement nutrient reduction programs such as BMPs aimed at a

minimum of achieving nutrient targets in the Big Bend Region. Focus on the most

sensitive areas first. May use the results of the Conservancy's Site Assessment to identify

the most sensitive areas.

Strategy NUTR, B-1: Support continued and expanded implementation of BMPs in

Suwannee Basin (WMDs may have data on dairy & chicken farms BMP

implementation).

Action Steps:

a. Identify how additional partnerships may be able to enhance or expand the

effective implementation of BMPs to reduce nutrient loading in the Suwannee

River Basin.

b. Engage additional partners in BMP implementation where warranted.

Strategy NUTR, B-2: 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.

Action Steps:

a. Inventory septic systems in the planning area and identify areas where their

density may exceed the capacity of natural systems to assimilate the nutrients

effectively.

b. Work with local governments to develop programs that require advanced septic

systems as systems are replaced. This may include identifying funding sources for

these programs.

Strategy NUTR, B-3: Support the WMDs 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.

Action Steps:

a. Identify any impediments faced by the WMDs to retrofit existing stormwater

treatment areas;

b. Partner with the WMDs to facilitate and accelerate the retrofits focusing on the

most sensitive areas first.

Strategy NUTR, B-4: Encourage the WMDs and local governments to champion the

creation of incentives for placement of advanced septic systems (could be tax incentives).

Appendix 3. Workplan: Action Steps and Timeline to Accomplish the Top-Rated Conservation Strategies

YEAR 1 YEAR 2

Q1 Q2 Q3 Q4 Q1 Q2 Strategy HAB, A-1: 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.

Action Steps: a. Assemble data and existing information from existing water quality monitoring programs from the Big bend CAP planning area;

b. Where data allows, identify likely natural background levels of nutrients in coastal waters;

c. Recommend additional water quality monitoring that may be required to adequately monitor water quality in the

planning area.

Strategy HAB, A-2: Push for congressional support (i.e., funding) to address HABs now "while the iron is hot". Now on the minds of our congressional

representatives.

Action Steps: a. Identify likely supporters for increased congressional funding and their actions towards increasing support;

b. Create/assemble marketing materials that can be distributed to increase congressional support for HAB research and

remediation.

c. Encourage likely supporters not currently engaged with congressional requests for support to become so.

Strategy HAB, A-3: Conduct/support research that builds on existing knowledge to identify the cofactors that trigger HABs.

Action Steps: a. Establish a coordinating body to share HAB research, determine future advancements and promote support for future research and

remedial actions.

b. Evaluate progress towards understanding what triggers HABs and implementing remedial actions on an annual basis;

and

c. Adapt research and remediation plans as recommended by the evaluation.

c. Submit this proposal of recommended changes to the appropriate agencies; and

d. Promote the proposal widely.

Strategy DEV, A-2: Promote soft shoreline alternatives to hardened shoreline. Promote planting of native plants, for example. Implement an

education program along the lines of the following: Natural Resource Conservation Service, Partners for Fish and Wildlife, and Florida Yards and

Neighbors. Hold a summit to develop what people should be doing then disseminate the information through SeaGrant, etc.

Action Steps: a. Convene a meeting with appropriate stakeholders to develop educational materials/programs that educate people about and

promote soft shorelines as an alternative to hardened shorelines;

b. Identify funding sources to develop and print the identified programs and materials;

c. Implement the educational program and develop the materials for printing. Print the educational materials;

d. Promote the educational program and disseminate the print materials to appropriate audiences.

Strategy DEV, A-3: Ensure adherence with the coastal construction control line (CCCL) rules and promote shifting the CCCL landward.

Action Steps: a. Determine how well the CCCL rules have been adhered to in the planning area;

b. Where violations or variances to the CCCL rules have occurred, determine why;

c. Working with other stakeholders, develop recommendations that will avert further violations and/or

variances to the CCCL rules;

d. Convene a working group to determine if CCCL rules are sufficient to protect coastal natural

resources in light of the best available scientific evidence on global climate change and its impacts such

as sea level rise;

e. If the current CCCL rules are determined to be insufficient, engage the working group in a

effort to develop a science-based proposal for CCCL revision;

f. Submit this proposal to the appropriate state authorities and promote it widely.

Strategy DEV, B-1: Purchase more coastal conservation lands and easements.

Action Steps: a. Prepare a geospatial inventory of coastal uplands in the Big Bend CAP planning area from the shoreline extending inland 1 mile

that depicts the conservation and ownership) status (private versus public, relevant agency and purpose. Revise the inland boundary

of this analysis if warranted to reflect potential sea level rise impacts;

b. Rank the importance of acquiring lands not currently in some form of conservation status;

c. Identify programs and funding sources under which these inventoried lands may be acquired;

d. Submit acquisition proposals to appropriate programs in order of priority to the greatest extent

practical;

e. Work to create/renew land acquisition funding programs if necessary.

Strategy DEV, B-2: Develop a mechanism to improve communication between developers and the conservation community to circumvent problems
