OUTLINE 1. Background & context since GM26 2. Tropical Americas Workshop Panama Findings & Outcomes Workshop Report 3. GCRMN Regional Networking & Support
Improvement of coral reef management requires a permanent commitment and an adaptive approach. ICRI Framework for Action 3 June 1995
Core Team Members Jeremy B.C. Jackson, GCRMN Science Director Vivian Lam, Research & Deputy GCRMN Coordinator Katie Cramer, Data Analyst Mary Donovan & Alan Friedlander, Data Analysis, Fishes Andy Hooten, GCRMN Global Coordinator
Two broad objectives 1. Scientific re-evaluation Compile all available rigorous quantitative data for corals, algae, fish, and mobile invertebrates for each ocean region - iconic reef sites Misali Island, Pemba, Zanzibar, March 2009 2. Convene interactive regional workshops participation by data contributors & GCRMN regional network members
Workshops to enhance capacity & strong communication Data contributors Academics Within the region leaders Others with monitoring/research experience in the region GCRMN Nodes & network members, local monitors Increase regular dialog & consultation exchange of views & information joint publications & reporting
Tropical Americas Region Workshop held in Panama, Smithsonian Tropical Research Institute 36 participants, 18 countries Belize ICRI Co-chair participated Other GCRMN Network Members
Scientific objectives new GCRMN 1. Document status and trends for all major components of global coral reef ecosystems to determine extent to which protection from local impacts may increase resilience to climate change 2. Build effective standardized infrastructure for future monitoring and assessment 3. Make assessment results widely available to help guide policy and action
Phase 1: Status and trends for Caribbean reef ecosystems Three basic questions: 1. How much variability exists among reefs in different places and settings? 2.To what extent is this variability determined by differences in the kinds and extent of human disturbance? 3.How can we most effectively use the results of these analyses to reduce or reverse coral reef decline?

Summary preliminary Caribbean GCRMN 1. Meta-analysis of ecological change combining data from different sites obscures ecologically important differences. 2. The Caribbean isn t hopeless although the situation is dire. Some places have considerably more coral than the average for the GBR [where coral cover also varies several-fold with distance from shore and along the coast away from direct human impacts]. 3. Caribbean reefs with the highest surviving coral cover and least macroalgae are small, moderately populated and prosperous islands with little land based pollution and varying protection from fishing. 4. Thus a combination of very large MPAs and strong regulation of fishing and pollution could significantly increase Caribbean coral reef health.24
