Summary extracts from Outlook Report 2009

• Five of the six species of marine turtle on the Great Barrier Reef have declined; the loggerhead, flatback and green turtle nesting populations appear to have stabilised or are now increasing.
• Current cumulative pressures on marine turtles in the Great Barrier Reef include incidental capture in some fishing gear, boat strike, ingestion and entanglement in marine debris, illegal hunting, unsustainable traditional hunting, coastal development impacting nesting beaches and hatching success, and disease. Future loss of habitat for nesting sites from predicted sea level rise poses an extreme risk to nesting species.
• The impacts of recreation (not including fishing) are mainly localised in inshore areas. The projected increase in recreational use as a result of population growth is likely to result in greater localised effects on the ecosystem.
