Scenario 4. Global Climate Change

This decision tree is a sample scenario that can guide the selection and interpretation of indicators where managers are

concerned with the threat of global climate change. The most significant concern is the increased frequency and intensity

of coral bleaching events and the ability of coral reefs to persist through these events. For local marine managers, the

effects of global climate change often cannot be addressed directly at the local scale. One strategy is to incorporate

some coral reef areas that exhibit more resilience or resistance into existing MPAs. Another strategy is to temporarily limit

human activities or disturbances on reefs that are experiencing bleaching.

This sample decision tree therefore focuses on these three areas to monitor:

· Status of key ecological parameters impacted by GCC (e.g., coral bleaching and mortality)

· Level of main threats (e.g., coral bleaching index, cholera or other diseases)

· Effectiveness of interventions (e.g., marine area within MPAs, environmental sustainability index)
