The Global Invasive Species Database (GISD) is a free source of information about invasive alien species. It covers all taxonomic groups from micro-organisms to animals and plants, in all ecosystems. The GISD aims to increase public awareness about introduced species that negatively impact biodiversity, and to facilitate effective prevention and management activities by providing easy access to authoritative invasive species information.
The database is available through http://www.issg.org/database/welcome/.
