Global Register of Introduced and Invasive Species

The Global Register of Invasive Species (GRIS) was developed as a concept and prototype by the IUCN SSC Invasive Species Specialist Group (ISSG) in 2006 as part of a project undertaken for the Defenders of Wildlife on the Regulation of Live Animal Imports into the United States. The concept was revisited and expanded by the ISSG to address Aichi Target 9 and support its achievement- with the development of the Global Register of Introduced and Invasive Species (GRIIS) GRIIS hosted by the ISSG compiles annotated and validated country-wise inventories of introduced and invasive species. Development and population of the GRIIS was undertaken by the ISSG within the framework of activities of the Information Synthesis and Assessment Working Group of the GIASIPartnership.

A brief summary of the process

  • The compiler team will conduct a comprehensive lit review of credible source information and develop a draft annotated country inventory of introduced and invasive species.
  • Annotations include higher taxonomy, environmental system, biological status (provenance and invasiveness), Date of introduction or first report, Introduction type and pathway, impacts (including evidence of impact and a yes/no if the species is solely a weed, pest or disease of agriculture)
  • Country editor/editors will be identified and consulted with for advice including knowledge of any key resources
  • The draft inventory will be posted on the GRIIS online resource. Every species record will include a check (indication) if the status has been verified as feedback is received. In cases where there is evidence of impact gathered from peer-reviewed literature or reports, the species status will be considered 'verified'
  • Every country will have a profile page that includes the names of the editors as well as the complete reference list of sources consulted. Also included will be the status of the verification process and currency of data
  • Draft inventory will be submitted to the editor/editors- allowing a 12 week timeline for return.
  • Revisions will be implemented based on feedback.
  • Updates will be implemented six monthly based on change in status of species or any new listings (Our plans are to provide online access to nominated country editors to provide updates and make revisions with the availability of new information through a moderated process)

Notes on the annotations

  • Higher taxonomy- Kingdom, Phylum, Class, Order, Genus and Species with species authority. Species names as presented in the source information is recorded. Once we have completed an inventory we will run the list through a script provided by GBIF which will indicate if the species name is accepted, whether it is a synonym etc. This will help us to apply a consistent taxonomy across all inventories
  • Environment system- terrestrial/ freshwater / brackish / marine/ host and combinations
  • Provenance- a) as recorded by the source information b) as interpreted by the compiler - three options applied are alien, native/alien (if the species is native in a part of a country and alien in another part), provenance uncertain/cryptogenic
  • Invasiveness- a) as recorded by the source information b) as interpreted by the compiler - three options applied are invasive/uncertain/not specified
  • Impacts recorded- a binary choice of Yes/ No; type of impact (on ecosystems, species or socio-economic); evidence of impact; source information
  • Status of Country Inventories. The verification process is on-going and not all country inventory verification is complete. All species with a ‘YES’ Verification tick are verified species records

The development of the Global Register of Introduced and Invasive Species (GRIIS) is an initiative supported by the Secretariat of the Convention on Biological Diversity (CBD) and is implemented within the framework of the Global Invasive Alien Species Information Partnership. The IUCN SSC Invasive Species Specialist Group is the project lead. The resource will be a support to Parties to make progress to Achieve Aichi Target 9 -in the development of their National Biodiversity Strategy and Action Plans, their National Invasive Alien Species Strategy and Action Plan, target setting and monitoring
