The Country Compendium of the Global Register of Introduced and Invasive Species (GRIIS) is a collation of 196 individual country checklists of alien species, along with a designation of those species associated with evidence of impact at a country level. The Compendium provides a baseline for monitoring the distribution and invasion status of all major taxonomic groups, and can be used for the purpose of global analyses of introduced and invasive species, including regional, single and multi-species taxon assessments and comparisons. It enables the consideration of gaps and inferred absences of taxa at the country level, and provides a means for short to medium term refinement of GRIIS Checklists.
The Compendium is instrumental, along with data on first records of introduction for countries, for assessing and reporting on invasive alien species targets, including those of the Convention on Biological Diversity and Sustainable Development Goals.
