Introduced plants are a major problem throughout Australia. Introduced species are listed as one of the most severe threats to biodiversity in Australia, and managing them costs Australia around $4 billion per annum. The information we gather in this project will tell us what sort of changes introduced plants undergo when they arrive in Australia; how quickly plants can adapt to a new environment, and what sort of species are best able to adapt to new conditions. We will also ask whether introduced species are still adapting to Australian conditions. If so, then we might expect even more naturalised species to become problem weeds in the future. This sort of knowledge is fundamental to our ability to develop appropriate control programs.

引进的植物是整个澳大利亚的一个主要问题。引进物种被列为对澳大利亚生物多样性最严重的威胁之一，管理它们每年花费澳大利亚约40亿美元。我们在这个项目中收集的信息将告诉我们引进的植物在到达澳大利亚时会经历什么样的变化;植物适应新环境的速度有多快，以及什么样的物种最能适应新的条件。我们还将询问引进的物种是否仍在适应澳大利亚的条件。如果是这样的话，那么我们可能会期待更多的归化物种在未来成为问题杂草。这种知识对于我们开发适当的控制程序的能力至关重要。
