To facilitate the discussion, a set of internationally agreed terms and definitions were presented, as retrieved in:

•  The Glossary of terms of the Convention on Biological Diversity, available at https://www.cbd.int/invasive/terms.shtml, which compiles definitions from different sources, and
• The Regulation (EU) No 1143/2014 of the European Parliament and of the Council of 22 October 2014 on the prevention and management of the introduction and spread of invasive alien species, available at: https://eur-lex.europa.eu/legal-content/EN/TXT/?qid=1417443504720&uri=CELEX:32014R1143
   

A definition of a Darwin Core term was also presented: https://dwc.tdwg.org/terms

In the slides adressing terminology, X indicates the main term used in each case. When there is no X, no definition was provided, but the term was used in the text.

In the slides adressing definitions, concepts stressed during the discussion are highlighted in yellow.
