    Introduction:
    Species Notes for this Location:
    Outbreaks of the coral-feeding starfish Acanthaster planci occurred on reefs around Potter Island in 1966(?) and 1984 (GBRMPA database, in Done 1988).
    Management Notes for this Location:
    Done (1988) used a computer modelling system to estimate recovery times for these locations to range from 9 years to greater than 100 years. Estimates increase with increasing coral size and are based on data collected for Porites spp.
    Location Notes:
    Impacts:
    Modification of natural benthic communities: Outbreaks of the coral-feeding starfish have caused high levels of mortality and injury in corals on the Great Barrier Reef. In surveys conducted in 1985 and 1986, it was estimated that the starfish had decimated a quarter of the massive Porites spp. corals surveyed at five reefs (John Brewer, Rib, Potter, Feather and Green Island) (Done 1988).
