Resident Josie Parisse said she was horrified to find at least 11 dead oblong turtles scattered on a street alongside Bibra Lake on Wednesday morning. WARNING: GRAPHIC IMAGES She said some of the animals were carrying eggs. "I was in complete shock, I was bawling my eyes out," she said. "It's common that they cross the road at this time of year and every now and then you find maybe one or two, but I've never seen so many dead ever."

"It's a 50 kilometre per hour zone, it's not a dark street, there are streetlights — it's not hard. "There's ones on the side of the road where you would have had to have purposely swerved on to the gravel to have hit it."

Rangers have spent the day cleaning up the road. "We will be undertaking an assessment to determine if there are other ways in which we can prevent a similar occurrence happening in the future," he said. Department of Biodiversity, Conservation and Attractions wildlife officer Cameron Craigie said the turtles would have been seeking drier land in which to lay their eggs.

"As it starts warming up that's when they start making moves. "We've had a call about a turtle that made its way into a drain and was flushed down to the beach. "They turn up in all different areas — they sometimes can get down kerbs but then can't get back [up] so they spend a lot more time on the road than they need to." Start of warmer weather means more animals on the go Mr Craigie said people on the road needed to pay close attention to crossing animals. "You've got your ducklings on the road all over the place," he said. PHOTO: A mother duck and ducklings use a road crossing.

The Department encouraged anyone who finds injured fauna on the road to contact the Wildcare Helpline on 9474 9055.
