<\/p>\nThey\u2019re creatures often associated with tropical waters and exotic shores, but a Sydney research project has revealed one of the world\u2019s most enigmatic marine animals is really as local as our backyard magpies and ringtails.<\/p>\n
Green sea turtles and their more elusive cousins, the hawksbills and loggerheads, are capable of some of the most epic migrations on earth, yet preliminary data from a tracking effort spearheaded by Taronga Zoo suggests they spend much of their time in NSW as homebodies who stick to one particular beach or bay.<\/p>\n

\u201cThey are staying inshore and residing in coastal bays and estuaries,\u201d Dr Jo Day, a conservation biologist at Taronga, said. \u201cOur tracking data is showing that a lot of our turtles are residents to those areas, and it\u2019s surprising how small their home ranges are. That\u2019s really new, exciting information.\u201d<\/p>\n
One green turtle didn\u2019t leave Freshwater beach during a three-month tracking stint between February and May. It\u2019s an animal capable of crossing oceans, but barely bothered to make the measly two-kilometre trip to the turtle (and snorkeller) hotspot of Cabbage Tree Bay off Shelly Beach.<\/p>\n
\u201cIt\u2019s still around,\u201d Day said of the Freshwater turtle. \u201cWe have lots of public sightings of that turtle, so it does seem to be a resident of that area.\u201d<\/p>\n
Day said the research collaboration between Taronga, the Sydney Institute of Marine Science, NSW National Parks and the Gumbaynggirr Land and Sea Rangers was aimed at translating local expertise to scientific knowledge that could galvanise conservation efforts.<\/p>\n
\u201cOur overarching aim is to understand what type of habitats marine turtles are choosing to forage and rest, and the ultimate aim is to protect those environments.\u201d More data is needed to firm up the researchers\u2019 findings.<\/p>\n
