Description
This map shows an aggregate of COTS outbreaks from 1985 – 2017 for the Great Barrier Reef. It shows the outbreak levels for the worst 10% of the years during this period. Note that this does not include outbreaks in the Coral Sea as no routine surveys occur in this region. Interactive version of this map.
