Impact can of course be defined in different ways, driven by different objectives, such as its usage in EICAT where it is defined as a measurable change to the properties of an ecosystem caused by an alien taxon (Hawkins et al. 2011), where impact is a function not only of the per capita effect of an individual organism, but is a combined function of the effect, abundance and range size of a species. This usage is relevant to the purpose of GRIIS, and consistent with the concept of impact as formulated by Parker et al. In GRIIS, species are recorded as having an impact (as 'yes' under 'isInvasive') if there is evidence of the species negatively impacting biodiversity, and including species that are widespread, spreading rapidly or present in high abundance (Pagad et al. outside the range it occupies naturally or could not occupy without direct or indirect introduction or care by humans) and includes any part, gametes or propagule of such species that might survive and subsequently reproduce.Īn Invasive alien species means an alien species which becomes established in natural or semi-natural ecosystems or habitat, is an agent of change, and threatens native biological diversity. The International Union for Conservation of Nature, (IUCN) describes an Introduced/ Alien and Invasive alien species as follows:Īn Introduced/ Alien species means a species, subspecies, or lower taxon occurring outside of its natural range (past or present) and dispersal potential (i.e. This annotated checklist is focused on introduced (alien) and invasive species that are known to occur on Tenerife, Islas Canarias, Spain The resource will be a support to countries to make progress to achieve Aichi Biodiversity 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. ![]() This annotated checklist is of introduced (alien) and invasive alien species known to occur on the island of Tenerife, Islas Canarias an Autonomous community of Spain Only verified checklists/ species records are presented on the GBIF Portal. Verified checklists/ species records as well as those under review are presented on the online GRIIS website ( Individual species records are flagged with a ‘yes’ for verification. Species belonging to all Kingdoms are covered as well as occurring in all Environment/systems.Ĭountry/ Territory/ Island checklists are reviewed and verified by networks of country or species experts. Phase 2 which is on-going, aims to achieve global coverage including non-party countries and all overseas territories of countries e.g. Phase 1 of the project focused on developing validated and verified checklists of countries that are Party to the Convention on Biological Diversity (CBD). The Global Register of Introduced and Invasive Species (GRIIS) presents validated and verified checklists of introduced (alien) and invasive alien species at the country, territory, and associated island level.
