Invasive alien species were highlighted as one of five main direct drivers of global diversity declines within the recently published Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Global Assessment report on biodiversity and ecosystem services. Recently IPBES announced the scope for a thematic assessment of invasive alien species and their control; this will be the first comprehensive assessment. The assessment will comprise six chapters: 1. Introduction; 2. Analysis and synthesis of past and future trends in the spread, pathways, evolutionary change and distribution of invasive alien species and gaps in existing knowledge; 3. Analysis and synthesis of direct and indirect drivers responsible for the introduction, spread, abundance and dynamics of invasive alien species; 4. Global and overall analysis and synthesis of the environmental, economic and social impact of invasive alien species; 5. Effectiveness of past and current programmes and tools for the global, national and local prevention and management of invasive alien species and their impacts; 6. Future options for the prevention and management of invasive alien species and analysis of possible support tools for decision makers. A number of overarching themes are being developed to guide the assessment including interactions of invasive alien species climate change.
The IPBES assessment of invasive alien species and their control will bring together more than 70 experts spanning diverse disciplines. The completed assessment will be presented to the tenth session of the IPBES Plenary composed of representatives from over 130 member States.
