To assess the proportion of marine turtles in Australia potentially at risk from light pollution.
Type of Study:
In Australia the majority of nesting turtles appear to be at low risk but the industrialised coast of WA (e.g. north-west shelf) and the urban coast of Qld contains globally significant turtle populations that have high proportions of nesting areas exposed to light pollution (24 – 60%). Species most at risk are hawksbill, flatback, green and loggerhead turtles. The risk to turtles from light generated by industrial developments in WA appears significantly higher than at any other location.
Light-mitigation strategies should be implemented along the Australian coastline, and marine turtle managers should recognise the huge potential to the disruption of turtle nesting that light generated by industrial and urban developments may cause.
