The Invasive Species Specialist Group (ISSG) aims to reduce threats to natural ecosystems and the native species they contain by increasing awareness of Invasive Alien Species (IAS) , and of ways to prevent, control or eradicate them. The ISSG promotes and facilitates the exchange of IAS information and knowledge across the globe and ensures the linkage between knowledge, practice and policy so that decision making is informed.
The three core activity areas of the ISSG are policy and technical advice, information access and information exchange.
The ISSG is involved in several mechanisms which facilitate access to IAS data and information. The ISSG publishes a biannual newsletter ´Aliens´. ´Aliens´ features articles on issues related to IAS.
The ISSG has developed and manages the Global Invasive Species Database (GISD) an online, freely available premier resource of information on IAS, their ecology, spread, management and impacts. The ISSG has developed a thematic database called IBIS- (Island Biodiversity and Invasive Species) focused on impacts of IAS on native species on island ecosystems and their management. The ISSG also hosts the Database of Island Invasive Species Eradications (DIISE) developed by partners that include Island Conservation (IC).
The ISSG promotes information exchange through several initiatives. The ISSG manages Aliens-L, a list server that allows users to freely seek and share information on invasive species and related issues. Aliens-L has over 1145 subscribers. The ISSG operates a dynamic resource and information Referral service that has grown over the years, continuing to meet the needs of stakeholders. The Referral service provides invasive species and related information to stakeholders on request and facilitates linkages between global experts and practitioners. The ISSG is working on developing Invasives Species Practitioner Networks on island groups such as the Western Indian Ocean Islands, the Pacific and the Caribbean
