Climate Change
Major Threats
Rising sea temperatures
Sea level rise
Changing ocean chemistry
Increasing severity and
frequency major storms
Changes in precipitation,
droughts & land run-off
Changing ocean currents
Resilience Principles
for MPA Network Deign
•Spreading risk through representation and replication
•Identifying and protecting critical areas, particularly those
more likely to survive
•Understanding and incorporating patterns of connectivity
•Ensuring reefs are as healthy as possible

Global bleaching reports to 1998 (ReefBase)
Global bleaching reports to 2003 (ReefBase)
Wide variety of marine habitats in close proximity
Shallow water (coral reefs, seagrasses, mangroves)
Deepwater habitats (oceanic waters, seamounts etc)
• Most in good to excellent condition, high conservation value:
• Coral Triangle (global center of marine biodiversity)
• Globally significant oceanic waters (toothed whales & pelagic fish)
Kimbe Bay
Large, well defined bay (140 x 70 kms)
Natural seascape for MPA network design
Dramatic bathymetry: coastal shelf (to 200m), most deep (600 to >2000m)
