Without efficient application of limited conservation resources, more species will go extinct and invasive species will continue to proliferate. With a better understanding of extinction processes, a higher benefit:cost ratio will ensure better outcomes for biodiversity. We will directly address (1) the sustainable use of Australia's biodiversity by providing evidence-based support for minimum viable population size targets to avoid extinction; (2) responding to climate change by determining the species- and environmentally specific contexts leading to elevated risks of extinction; and (3) protecting Australia from invasive diseases and pests by determining density targets that maximise eradication success.

如果不有效地利用有限的保护资源，更多的物种将灭绝，入侵物种将继续繁殖。随着对灭绝过程的更好理解，更高的效益成本比将确保生物多样性取得更好的成果。我们将直接解决（1）澳大利亚生物多样性的可持续利用，为避免灭绝的最小可行种群规模目标提供基于证据的支持;（2）通过确定导致灭绝风险升高的物种和环境特定背景来应对气候变化;（3）通过确定最大化根除成功的密度目标来保护澳大利亚免受入侵性疾病和害虫的侵害。
