  1. Ecosystem Approach to Managementin DFO MaritimesImplementation Experience Bob O'Boyle & Tana Worcester Bedford Institute of Oceanography Dartmouth, Nova Scotia

  2. Background • Two 'Laboratories' • Eastern Scotian Shelf (ESSIM) • One of first DFO pilots (started in 1998) • Governance (Oceans lead) • Ecosystem objectives (Science lead) • Gulf of Maine Area (GOMA) • Emerging since first interaction with US in 2004 • Challenges • Tension between management pragmatism & scientific elegance • Evolving national policy & guidelines

  3. Current Eastern Scotian Shelf Integrated Management Planning Area Ongoing Dialogue on Western Boundary & Inshore / Offshore Boundary

  4. Planning Hierarchy Overarching Conceptual Objectives National Ecosystem Objectives Planning Area Conceptual Objectives ESSIM Area Ecosystem Objectives Planning Area Operational Objectives Monitor Ecosystem States Control Cumulative Impacts of Sectors Sector Operational Objectives Control Impacts of Sectors Sub - Sector Operational Objectives Control Impacts of Sub-Sector

  5. Identification of Issues & Ecosystem Components in ESSIM Area • Determined IM Area specific Issues • Key issues from Science & stakeholder perspective • Working Groups & Workshops • Product was layman’s understanding of Issues at IM Area Level • Organized by national ecosystem objective

  6. NationalEcosystem Objectives(2001 Workshop) Draft ESS Ecosystem Objectives developed consistent with this framework

  7. Issues & Ecosystem Components in ESSIM Area

  8. Draft Ecosystem Objectives for ESSIM Area Driven by issues specific to ESSIM Area

  9. ESSIM Area Ecosystem Objectives • Ecosystem Objectives released in Fall 2005 in draft ESSIM Plan • Still high level • Further refinement upon determination of: • Ecological & Biological Significant Areas (EBSAs) • Ecological & Biological Significant Species • Degraded Areas • Depleted Species • Need for formal prioritization process • Quantitative vs Qualitative Risk Analysis • Risk of NOT achieving overarching objective

  10. IM Area Operational Objectives • ESSIM Science WG developed workplan by ecosystem objective to define operational objectives • Some completed (e.g. Primary Productivity, Sediment, cod, plaice, halibut) • Project put on hold to await refinement of ecosystem objectives • GOMA Science WG developed draft operational objectives based upon early ESSIM work • Focus on monitoring • Specific to fisheries • Regional DFO Workshop (October 2005) • Engage & educate all sectors on integrated management • Opportunity to compare / contrast ESSIM & GOMA approaches • Developed generic working set of IM area operational objectives

  11. IM Area Operational Objectives

  12. Conservation of Benthic Communities • Oceans requested Science advice on this objective in 2000 • Three phase process • June 2001: Benthic Classification Systems • July 2005: Classification of Scotian Shelf Benthic Community • 2006/07: Characterization on impacts, indicators & reference points • Since initiation of process, complementary related initiatives (e.g. EBSA) underway

  13. Scope for Growth Based on Southwood Model High Productivity (Benign) Low Productivity (Adverse) Highest Risk to Impact Stable Lowest Risk to Impact Disturbance e z Wave height/period i t Disturbed s n h n e t i r p r a u r e G D C Food Availability Water temperature Variability in temperature Oxygen Saturation Stratification

  14. Multibeam Profiling

  15. Areas of Potentially Higher Risk High Risk Areas

  16. Sector Operational Objectives • Decided to engage fishing sector on EBM • Presented generic IM area operational objectives to Scotia-Fundy Industry Roundtable (Jan 2006) • Fishing industry agreement to evaluate Fisheries Management Plans (FMPs) against objectives

  17. Evaluations Completed Maritimes Fisheries Management Plans

  18. Preliminary Evaluation ofGeorges Bank FMPs • Blue: high relevance that currently receive attention • Red: high relevance & require attention • Others: of low relevance

  19. Monitoring & Reporting • Regulatory • Performance indicators • Ecosystem • Contextual indicators • Study of ecosystem processes e.g. causality • Changes in reference points e.g. regimes shifts • Suite of 60+ indicators reported in 2003 Ecosystem Status Report • Now working on set for Gulf of Maine Area • More formally linked to ecosystem objectives

  20. Grey seals, pelagic fish abundance, invertebrate landings, fish species richness, phytoplankton Bottom temp., exploitation, groundfish biomass & landings, growth-CHP, avg. fish weight, copepods 1970 1975 1980 1985 1990 1995 2000

  21. Why these Changes? 1) Top - Down Control?

  22. Why these Changes? 2) Increased Stratification? Would favour proliferation of pelagic food web & limit flux of nutrients to benthos

  23. Why these Changes? 3) Cooling? Cooling & increased advection associated with increases in cold water species

  24. 4TVW Haddock and Environment 0C Tons 0C Management Reference Points would be modified based upon environment Implications for inclusion of 'Regime Shifts' in management actions

  25. Future ESR Proposal Suite of Operational Objectives At Planning Area Level Would define Ecosystem Health Colour indicates Performance Of Operational Objective Green: Good Yellow: Caution Red: Poor

  26. Lessons for Workshop • Develop common understanding of high level objectives • Compare regional sets of objectives & associated issues specific to planning area • Stakeholder workshop? • Planning area level • Contextual indicators • Ecosystem processes • Relevant to RP / RDs • Fishery level • Regulatory / tactical indicators & Reference points / Directions • Management action? • PICES Report • Keep general but move towards objectives structure • Maintain array of indicators Time trends by functional group & area

  27. Final Thoughts • Need Stakeholder buy-in to IM • IM provides framework that links policies & initiatives • Need Manager buy-in to IM • Currently putting FMPs into framework to show what exists now & what gaps exist • Need Science buy-in to IM • Currently reviewing science work plans in relation to ecosystem objectives

  28. Thank You!

  29. Outline • Background • Management Area Boundaries • Planning Hierarchy • Monitoring & Reporting

  30. Developments since 1998

  31. Management Area for EAM • Ecological Features across wide range of spatial scales • Many existing administrative areas for fisheries & other ocean uses • Challenge • Need to find consensus amongst diverse perspectives

  32. Scientist Perspective 2004 Ecoregions Workshop ESS GOMA

  33. Fishery Manager Perspective4VsW Cod 4VsW Cod

  34. Ocean Manager PerspectiveESS Gully MPA

  35. Proposed Solution Select management areas based on established governance structures Use nested approach Ecological features larger than IM area require coordinated management actions amongst relevant contiguous areas Small ecological features require fine spatial resolution of management actions within IM area

  36. Two Types of Objectives • Conceptual Objective or Goal • Interpret legislative mandate to be understandable to broad audience • E.g. Restore Coral Community Biodiversity to pre-1980 levels • Operational Objective or Strategy • Link between Conceptual Objective & Management Action • Specific enough to be clear to all • Refers to indicator (e.g., biomass) & reference point (e.g., 50,000 t) • E.g. Limit Area (sq Km) disturbed of Coral Community to 5000 sq km

Healthy fish stocks for the benefit of Canadians Rebuild or maintain biomass at optimum levels Restore abundance to levels comparable to the 1950-60’s Management Domain

  38. Steps to Operationalize ESSIM Plan • Identify conservation issues & impacted ecosystem components • Organize issues / components using national objectives as guide & state as ESSIM Ecosystem Objectives • Identify Ocean Sectors implicated in implementation of ESSIM Ecosystem Objective • Define Operational Objectives for ESSIM Area • Define Operational Objectives for each Ocean Sector
