Restoration of Australian ecosystems can only occur if we know what plants, animals and insects used to live in the area before 'pest' species were introduced. This project will use ancient DNA obtained from 'poo' and cave sediments, that is thousands of years old, to discover what species used to live where and when. The ancient DNA profiles of past ecosystems will allow us to make better decisions when trying to establish sustainable and 'natural' mainland and island sanctuaries. Ancient DNA is well preserved in some dry environments; this project will assess DNA preservation from sites all across Australia and use the DNA sequences to discover information about extinct animals and how past climate changes effected the native biota.

只有当我们知道在引入“害虫”物种之前，什么植物、动物和昆虫曾经生活在这个地区，澳大利亚生态系统的恢复才能发生。该项目将使用从“粪便”和洞穴沉积物中获得的古老DNA，即数千年的历史，来发现什么物种曾经生活在何时何地。过去生态系统的古老DNA图谱将使我们在试图建立可持续和“自然”的大陆和岛屿保护区时做出更好的决定。古代DNA在一些干燥的环境中保存得很好;该项目将评估澳大利亚各地遗址的DNA保存情况，并利用DNA序列发现有关灭绝动物的信息，以及过去气候变化如何影响本地生物群。
