全面预防外来植物入侵既不能做到，也不能忽视其影响。因此，只有在政府和市民的共同作用下，才能控制该物种可能产生的有害影响。为了本地物种的生存，对非本地物种进行明智和及时的管理是至关重要的。澳大利亚政府环境与能源部门制定了《1999年环境保护和生物多样性保护法》(EPBC Act)等法律，以确定主要的威胁物种，并制定和实施减少威胁计划(tap)(Australian Government, 2013)。
The extensive work for managing and preventing the spread of non-native introduced plants is being undertaken in Australia by people, conservation groups as well as the government agencies. The government keeps check over the types and number of weeds species that are becoming threat for the environment by releasing lists of hazardous plants. The highly widespread impact of the introduced non-native plants species has caused extinction of various local flora and fauna. Thus the government controls in order to prevent the harmful effect of the non-native plant species.
The complete prevention of invasion of non-native plant species neither can be done, nor can their impact be ignored. Therefore, with the collective effect of the government as well as citizens, the possible harmful effects of such species could only be controlled. For the survival of the native species, it is essential that the non-native species are managed wisely and timely. The Department of the Environment and Energy of the Australian Government has laid down legislations like Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) to identify the main threatening species as well as to make and implement threat abatement plans (TAPs)(Australian Government, 2013).
