Aichi Target 9 of the Convention on Biological Diversity’s Strategic Plan for Biodiversity 2011-2020
Target 9: By 2020, invasive alien species and pathways are identified and prioritized, priority species are controlled or eradicated and measures are in place to manage pathways to prevent their introduction and establishment.
Achieving and reporting on Aichi Target 9
One of the essential requirements for countries to be in a position to accurately assess and report on progress toward meeting Aichi Target 9  under the Convention on Biological Diversity’s (CBD) Strategic Plan for Biodiversity 2020, is a national inventory of invasive alien species present in the country . Baseline inventories can be established by drawing on a range of information sources and by combining species occurrence data collected in-situ, with alien status data which can be obtained from a variety of ex-situ sources if not already available (see Country examples).
Prioritization is indispensable for the management of biological invasions, as recognized by the Convention on Biological Diversity, its current strategic plan, and specifically Aichi Target 9 that concerns invasive alien species. McGeoch et al. (2016)  provides an overview of the process, approaches and the data needs for prioritization for invasion policy and management, with the intention of informing and guiding efforts to address this target.
