Chapter 6: Prevention of Invasive Plant Species
With the continued development of the global economy, biological invasion has become a pervasive and costly environmental problem, and it is one of the most critical factors threatening our environment, economy, and biological safety. Biological invasion is an essential element in global change and has been the focus of intensive prevention, management, and research activities worldwide. Prevention is the most effective and cost-efficient way to manage invasive plant species and reduce their negative impacts on ecosystems and the economy. To effectively prevent the introduction and spread of invasive species in new environments, multiple preventive measures can be taken, including conducting a comprehensive survey of biodiversity (biodiversity inventory), formulating strict laws and regulations, carrying out risk assessments, implementing early monitoring and rapid response strategies, and enhancing public education and awareness. Regulation of international trade and freight transportation includes strict biosecurity measures at borders and ports, such as quarantine and inspection, to prevent the unintentional introduction of invasive plant species. Early detection and rapid response involve monitoring and identifying potential invasive species before they become established and implementing swift action to eradicate or control them. Public education and awareness campaigns aim to increase general knowledge and understanding of invasive species and their impacts, encouraging individuals to take action to prevent their introduction and spread. Overall, preventing invasive plant species is a systematic project that requires collaborative efforts between government agencies, enterprises, and the public to implement effective management strategies and reduce the risk of introduction and spread.
