General Project Objective:
Develop draft technical guidance to assist marine resource management agencies in moving towards the use of an ecosystem-based approach in addressing their responsibilities
Reasons “Ecosystem-based Management” is a Current Issue
• Competing stake-holders and legislation
• Debate over the importance of different activities limiting resources (fishing, environment, predation, etc.)
• Issues with single species management
• Used as a scapegoat for lack of action
• Advancement of science and modeling
Fishing Down the Food web
Some Potential Outcomes of E-bFM
Protect important ecosystem services,
ID & maintain desired range in ecosystem state,
Conserve biodiversity,
Protect certain species,
Optimize total fish yield of the system,
Optimize yield of particular species, while
Providing for long-term economic viability.
Our role is to lay out the options and tradeoffs…….
Resolve some of the Confusion
• Ecosystem Management – NO, Ecosystem-based approach -YES
• Description of geographic focus area• Abundance measurements• Sustainability (at what level)• Management responsibility (who is on
1st?)
Ecosystem Approach should aid in:
• Clear direction (specific goals) for management
• More accurate and efficient response to general and specific information needs by sister agencies
• Improved public and political understanding of issues and tradeoffs
• Improved process to identify new information needs
This Project is building on:
• The Ecosystem Approach: Healthy Ecosystems and Sustainable Economics
by the Interagency Ecosystem Management Task Force (1995)
• Ecosystem-Based Fishery Management by the Ecosystem Principles Advisory Panel (1999)
• Experiences from various applications
The Interagency Ecosystem Management Task Force (1995) reported:
The ecosystem based approach is a method for sustaining or restoring natural systems and their functions and values.
It is goal driven, and it is based on a collaboratively developed vision of desired future conditions that integrates ecological, economic, and social factors.
It is applied within a geographic framework defined primarily by ecological boundaries
The desired outcome of the ecosystem approach is to restore and sustain the health, productivity, and biological diversity of ecosystems and the overall quality of life through a natural resource management approach that is fully integrated with social and economic goals.From Interagency Ecosystem Management Task Force (1995); and Ecosystem Principles Advisory Pane (1999)
Need to address “Goal Driven” at all levels including the Ecosystem,
Fish Communities, and Populations---------------------------------------------------
And move towards understanding of “healthy state” and/or shared vision of
the desired condition(within historic limitations)
Pillars of E-bFM
2. Assess current Ecosystem Status (Use same Metrics as for description of goals)
1. Goal Setting (Desired Vision for resources in a specific region)
3. Process to Achieve and Maintaine Goals (Management Tools)
1. Ecosystem Goals
Considerations:• Select understandable metrics
applicable to current, historic and future conditions
• Holistic approach should include biological, chemical, and physical parameters
• Agency specific issues as sub-sets
The Goal Setting Process
• Needs to consider historic conditions to “map desired future conditions”
• Needs to have goals clearly defined, not altruisms
• Needs to holistically address ecological tradeoffs
• Needs to be inclusive of all possible stakeholders
• Needs to include the major environmental and regulatory agencies

Evaluation of Different Ecosystem States
2. Assessing Ecosystem Status
• Multiple metrics– Biotic (resource and
non resource)– Abiotic– Human
• Long time series/trends
• Novel ways to package the information
CONTINUING CHALLENGES
• Identification of key topics• Define terms and applicability
to various scales• Identify generic indicators to
define condition of: • A fish population• Multi-species communities• Local and/or regional
environments
Scale Issues
Identify metrics for status and trends of environmental perturbations that could be monitored by/for:
– Watersheds
– Estuaries
– Nearshore regions
– Offshore regions
Determining the magnitude of ecosystem
change: Needs• From historic data,
models, and field observations improve understanding of ecosystem processes– Identify anthropogenic
stresses that influence biomass abundance and distribution
• Prioritize new information needs and support interagency funding initiatives
3. Achieving Ecosystem Goals
•Decision Criteria/Theory– Reference Points– Control Rules for Action
• Implementation/Follow-up– Monitoring– Enforcement
Process - Guidance (Options)for:• Criteria to guide the identification of
geographic range/area
• Indicators of ecosystem/species conditions
• Description of current ecosystem/species setting
• Description of historic state of the ecosystem/species
• Description of the desired state of the ecosystem/species
• Management options and some examples
• Evaluation and follow-up
• Identification and prioritization of crucial new information needs
Tools to influence the direction of ecosystem
change - harvestFishing pressure:• Effort control• Catch quotas• Time or area
closures• Gear modifications
or restrictions to efficiency
• Economic incentives• Ownership based
approaches
Tools to influence the direction of ecosystem
change - habitatEcosystem or Watershed
planning approach for: • Use of Marine Protected
Areas• Water quality standards• Stream access for fish• Wetland restoration and
protection• Restoration of shell reefs• Sand and gravel mining• Gear modifications to
protect habitat and forage
Effective ImplementationWill require:• improved and expanded inter- and intra-
agency communication– cooperation not just with fisheries but other
agencies and the public
• improve understanding of cause/effect relationships impacting fish abundance and distribution– this may focus on existing long-term data sets
• more information– how much, what type, and what priority need to be
determined
• Improved public understanding of management goals, decision process, and data requirements
• Re-linking management to place;
• Re-balancing of decision-making power;
• Increased likelihood of agreement on conservation and rebuilding targets.
