Many of you may have heard in the news of the Australian devastating floods. Monsoonal rains have drenched many catchments in Queensland, with floods reaching historical highs causing enormous damage to property, people's lives and our wildlife. It is estimated that these floods have affected 5,000 km5 of Queensland.
The home of the endangered Mary River turtle, Elusor macrurus, has peaked at 18.6m; the usual height for this time of the year is about 2-3m. Since early December, the river has had 3 floods over 9m. Over half of our annual rainfall fell during the first 2weeks of January. Every nesting bank has been flooded just as hatchlings would have been starting to emerge. Some have been underwater since early December. It is unfortunate as we had protected more nests this season than any other in the past 10years. The only recruitment this season will be from rescued clutches. Thankfully Tiaro Landcare volunteers were able to rescue and relocate some protected nests just before the floodwaters reached them.
Adult turtles have been observed congregating in backwaters and low flow gullies. However, with the velocity of floodwaters and over such a long period, many would be washed to the sea. The floods will also be impacting on their habitat and food sources.
