IUCN SSC Invasive Species Specialist Group: invasive alien species information management supporting practitioners, policy makers and decision takers.

The Invasive Species Specialist Group (ISSG) is a global network of scientific and policy experts on invasive species, organized under the auspices of the Species Survival Commission (SSC) of the International Union for Conservation of Nature (IUCN). ISSG aims to reduce threats to natural ecosystems and the native species they contain by increasing awareness of invasive alien species, and of ways to prevent, control or eradicate them. Since its establishment, over two decades ago, ISSG has taken the lead on collating, managing and disseminating global invasive species information, promoting practitioner networks and supporting development of policy and regulation aimed at reducing the insidious threat of biological invasions. All this has been accomplished through the development of knowledge products (such as the Global Invasive Species Database (GISD)), promoting dynamic networks such as Aliens-L, advocacy and publications. ISSG has actively catered to emerging needs with activities directed at key areas such as islands, threatened species, protected areas and developing invasive species indicators to support prioritising and monitoring management action. ISSG is working with partners advancing the adoption of a standardised framework of pathway categories and developing criteria for the ranking of known invasive species based on the type and magnitude of impacts. ISSG through participation in the Global Invasive Alien Species Information Partnership (GIASIPartnership) is working with other information providers supporting countries with current and authoritative information to effectively implement Article 8(h), Aichi Biodiversity Target 9 and other related decisions of the Convention on Biological Diversity (CBD) and other Multilateral Environmental Agreements (MEAs) such as the Convention on the Conservation of Migratory Species of Wild Animals (CMS) and the Ramsar Convention on Wetlands.
