Australia: King tides could have terrible impact on turtle numbers 6 Jan 2014

By Alyse Edwards.

Queensland National Parks rangers say king tides later this month (January) could have a devastating effect on nesting turtles at Mon Repos in Bundaberg.

Ranger Shane O'Connor says last year's floods caused severe erosion of the southern Queensland beach.

Mon Repos is a popular nesting site for loggerhead, flatback and green turtles from November to March.

But erosion along the beach has made it difficult for turtles to lay their eggs in higher, protected areas.

Mr O'Connor says another extreme weather event this breeding season would be devastating.

"Last year in January we actually had that cyclone move down the coast and we got that massive flooding event," he said.

"Combined with the high tides we lost a lot of our first dunes and we actually lost 60 per cent of our egg clutches.

"So obviously if you get lots of those sorts of events occurring you're going to get a big hole in their numbers, but we're doing relocations all through out the year to try to prevent that.

"The problem is if you have a king tide with either strong winds or a low air pressure, that will increase the height of that already high tide.

"In extreme cases that can actually create erosion of those dune systems, and when we get erosion of the dune systems, that's when we get those eggs exposed, and they will die."
