The Invasive Alien Species Assessment explores how invasive alien species affect nature and people globally. It analyzes the status and trends of alien and invasive alien species in all regions of Earth, and identifies major pathways for and drivers of the introduction and spread of such species between and within countries. The Assessment also assesses the effectiveness of management actions across scales and in various contexts. The Invasive Alien Species Assessment finally outlines key responses and policy options for the prevention, early detection, and effective control of invasive alien species and mitigation of their impacts in order to safeguard nature, nature’s contributions to people, and good quality of life. The Invasive Alien Species Assessment highlights that invasive alien species are a major and growing threat to nature, nature’s contributions to people, with, in some cases, irreversible changes to biodiversity and ecosystems. Invasive alien species also dramatically impact the economy, food security, water security, and human health, sometimes adding to marginalization and inequity. The Assessment demonstrates that with sufficient resources, political will, and long-term commitment, preventing and controlling invasive alien species are attainable goals that will yield significant long-term benefits for people and nature.
