More dugongs died this year than in all of 2010 because of Queensland’s summer of disasters. Ninety-six washed up dead on the Australian state’s coastline in the first seven months, compared with 79 for the whole of last year. Scientists believe most died of starvation after floods devastated their main food source, seagrass. Of the 96 dugongs, six died from human-induced causes such as boat strikes. Most deaths happened around Townsville, in the state’s north, and in Moreton Bay, in the south-east.
