Global Register of Invasive and Introduced Species - Norway

The Global Register of Introduced and Invasive Species (GRIIS) presents validated and verified national checklists of introduced (alien) and invasive alien species at the country, territory, and associated island level. GRIIS checklists are based on a published methodology, and supported by the Integrated Publishing Tool that jointly enable ongoing improvements and updates to expand their taxonomic coverage and completeness. The coverage of GRIIS is global including countries that are Party to the Convention on Biological Diversity (CBD), non-party countries and all overseas territories of countries, e.g. those of the Netherlands, France, and the United Kingdom. Limited numbers of checklists have also been developed for areas of high biodiversity value such as islands and protected areas. All kingdoms of organisms occurring in all environments and systems are covered. Checklists are reviewed by networks of country or species experts. Verified checklists, as well as those under review, are presented on the online GRIIS website in addition to being published through GBIF.
