1. Significant interest in the topic2. Some jurisdictions have EBM legislation3. Long application of EBM concepts in international law4. EBM in many instances simply improved fisheries management5. No single guide to marine EBM6. EBM being applied in dozens of countries

Ocean resources are inexhaustible
Key fisheries are inexhaustible.
Major fish populations decline;Traditional fishing communities breakdown; Ecosystems deteriorate.

What is Ecosystem-Based Management?

Pre 1886 Hawaiian managementPuako Bay & Reef
Juvik et al. 2008, Mueller-Dombois and Wirawan (2005)Ahupua’a
Pre 1886 Hawaiian management
• Closed areas• Closed seasons or bans while spawning• Letting some fish escape (MSY)• Holding excess catch in enclosures until
needed• Ban on taking small individuals• Use of lagoons when reefs too rough• Restrictions on taking seabirds or their
eggs• Restrictions on the number of fish traps in
an area• Bans on taking turtle eggs• Bans on taking turtles on the beach

Modern marine management
Hugo GrotiusMare Liberum (1609)
Cornelius van BynkershoekDe dominio maris (1702)
The “cannon shot rule”
John Selden Mare clausum (1635)
The ‘Common Property’ Rubric
Unregulated exploitation
Over-capitalization
Resource misappropriation
e.g., American lobster , 1895, New England, USA
Tragedies ComediesLocal ‘private fish property’ wars
Commoners lose access to the commons
Policy speaks for the fishers & Science speaks for the fish
e.g., Chesapeake Bay oysters, 1900, Maryland, USA
Kennedy and Breisch (1983)
Single-Species Management
All too common…
Declining populations
Northern Shrimp
Idoine (2006)

Multi-Species Management
Mayo and O’Brien (2006)
1. Minimum fish sizes by species2. Closed areas3. Protect spawning areas
Limitations to current approaches
• Fragmented ocean governance• Maintaining ecosystem elements• Managing diverse impacts• Lack of recognition of connections between:
– Ecosystem structure, functioning and services– Land and the sea– Marine habitats– Species – Diverse stressor– Knowledge and uncertainty
Guerry 2005
What is marine EBM?
Compass 2005
An integrated approach to management that considers the entire ecosystem, including humans with the goal to maintain an ecosystem in a healthy, productive, and resilient condition so that it can provide the services we want and need.
Perspectives on marine EBM (1) P
• Humans as ecosystem components• Sustainability• Goals• Sound ecological models and understanding• Complexity and connectedness• Dynamic character of ecosystems• Context and scale• Adaptability and accountability
Ecological Society of America elements of marine EBM
Christensen et al. 1996
Perspectives on marine EBM (2) P
• Fisheries should be managed to limit the impacts on the ecosystem to the extent possible
• Ecological relationships between harvested, dependent and associated species should be maintained
• Management should involve cross jurisdictional arrangements if required
• A precautionary approach should be adopted• Governance arrangements should ensure ecosystem
well-being and equity
Reykjavik Declaration of Responsible Fisheries in the Marine Ecosystem
FAO 2001
Perspectives on marine EBM (3) P
• Maintain natural structure and function of ecosystems
• Recognize that human uses and values are central to ecosystem management
• Base management on a shared vision of stakeholders
• Appreciate that all ecosystems are dynamic• Require a commitment of performance
monitoring and management
World Wildlife Fund elements of EBM
WWF 2002
Perspectives on marine EBM (4) PPikitch et al. (2004)
• EBM is a reversing the order of management priorities to start with the ecosystem rather than the target species
• Overall objective is to sustain healthy marine ecosystems and the fisheries they support.
Guerry 2005• EBM is about perceiving the big picture, recognizing
connections and striving to maintain elements of ecosystems

Which way lies successful EBM?
Step 1: Develop a common information base
I. Oceanographic dataII. Physiographic dataIII. Biological dataIV. Human use data
Information categories
1. Harmonize mapping of seacapes at a useful scale
2. Improve inventories of biodiversity
3. Monitor ecosystem services
Which way lies successful EBM?
Step 2: Describe and understand the system1. Ecosystem classifications
2. Food web models
3. Oceanographic and dispersal models
I. Marine regime II. Broad-scale ecosystems III. Structural geoforms/hydroforms IV. Vertical zone (benthic, pelagic) V. Macrohabitat (spatial/temporal) VI. Fine-scale habitats VII. Biotope (biosystems)
Sample Ecosystem Classification
4. Habitat suitability models
5. Socioeconomic models
Which way lies successful EBM?
Step 3: Risk assessment1. Determine what ecosystems are at
the greatest risk and the ecosystem services they provide
1. Provisioning services that produce goods, such as food and fresh water2. Regulating services that modulate ecosystem processes, such as disease control and
climate regulation3. Cultural services that provide nonmaterial benefits, such as education and recreation4. Supporting services, such as nutrient cycling and primary production that are
necessary for the generation of all other ecosystem services
Ecosystem services
Millennium Ecosystem Assessment (2005)
Which way lies successful EBM?
Step 4: Priority setting / identifying objectives1. Statement of the overarching aims and intended products
from the effort2. SMART (Specific, Measurable, Achievable, Realistic,
Timely)
Commercial fish speciesMarine mammalsSeabirdsFish communitiesBenthic communitiesPlankton communitiesThreatened or declining speciesEutrophication
Which way lies successful EBM?
Step 5: Select targets (goals) for objectives1. Determine the amount (abundance, area) of targets
required to meet objectives2. Can be tied to socio-economic goals in terms of area
(tourism, fishing, development) and abundance (ecosystem services, fisheries)
100% of Hawksbill turtle nesting sites30% of coral reef area< 100 ng /l TBT< 5mg Chl -a / m3
< 10,000 kg landings per day
Example targets
Which way lies successful EBM?
Step 6: Identify strategies to meet objectives1. Zone-based (place-based) management2. Fishery ecosystem plans for each zone3. Alternative marine governance systems4. Eco-certification5. Rights based fishery management6. Burden of proof7. Precautionary principle8. Education and outreach9. Legislation and policy10.Technological solutions
Which way lies successful EBM?
Step 7: Monitoring and adaptive management1. Implementation monitoring whether
strategies are implemented2. Compliance monitoring whether strategies
are being followed3. Effectiveness monitoring as to whether
strategies are meeting targets4. Revision of strategies and targets if
necessary
Western Everglades:The Big Cypress located on Shoshone Tribal Land abuts striking Everglades conversion for agriculture & livestock.
Eastern Everglades:The Loxahatchee Canal passes through the impounded north-eastern Everglades, carrying water from Lake Okeechobee to row-crop agriculture and development in West Palm Beach.
South Florida Ecosystem Restoration Task Force
South Florida Ecosystem Restoration Task Force
Marathon, The Florida Keys
1. Divide watersheds into eco-units2. A conceptual ecological model developed for each eco-unit3. Identify key environmental factors that must be maintained or
restored in each eco-unit4. Determine what flow are require d to maintain objectives in eco-unit
• Scientists talk to each other• Agencies cooperate• Science introduced into the
policy arena• Identified the problem (QQTD)• Managers and scientists speak
the same language• Federal cost sharing legislation
Conclusions and final thoughts
1. Policy makers dictate EBM but currently EBM doesn’t dictate policy
2. Marine EBM needs a single, agreed-upon definition3. EBM still a catch-all term for multi-species management
in many jurisdictions4. EBM is ‘tools-rich’ but ‘solutions-poor’5. No single EBM handbook6. EBM or EBM-like principles will soon preface all human
management in the natural world7. Marine biologists are central in the successful
implementation of marine EBM
