The Global Register of Introduced and Invasive Species (GRIIS) presents validated and verified checklists of introduced (alien) and invasive alien species at the country level. Phase 1 of the project has focused on developing validated and verified checklists of countries that are Party to the Convention on Biological Diversity. This annotated checklist is of introduced (alien) and invasive alien species known to occur in the State of Kosrae, one of the four states of the Federated States of Micronesia.Purpose
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 focused on introduced (alien) and invasive species that are known to occur in the State of Kosrae, one of the four states of the Federated States of Micronesia. The International Union for Conservation of Nature, (IUCN) describes an Introduced/ Alien and Invasive alien species as follows:An Introduced/ Alien species means a species, subspecies, or lower taxon occurring outside of its natural range (past or present) and dispersal potential (i.e. 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. An 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. 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. 2018). This usage is relevant to the purpose of GRIIS, and consistent with the concept of impact as formulated by Parker et al. (1999) and now widely used (e.g. Didham et al. 2005, Strayer et al. 2006, McGeoch et al. 2010, 2012, Vila 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. 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. 2015).

Quality Control
The draft checklist is compiled by collating data and information through a comprehensive literature overview. Additional steps implemented to control the quality of the data are described below. Taxonomic harmonization and normalization using the GBIF taxonomic backbone In order to harmonize all species names across countries, species lists are subjected to a normalization process in which taxon rank and taxonomic status are identified and assigned. Spelling and other errors in assigning species authorship are also corrected. Data validation The checklist compiler team completes a review and validates all the annotations especially those on provenance and 'invasiveness' status of the species based on evidence of impact. Data verification The checklist is submitted to a network of country editors for a review of both accuracy of records, annotations and identification of any significant gaps in the data. Data verification is an iterative process and the activity is declared completed on agreement of all relevant country editors. One of the key tenets of the GRIIS project has been engagement with country editors in the verification process and as custodians of their country checklists. While this has been possible in the majority of countries, the compilers have not been very successful in this engagement for a small number of countries. In these cases, the GRIIS compiler team has completed the validation of the species records while working on identifying country experts.Method steps

Additional info
Versioning The GRIIS checklists are dynamic and reflect the latest known status of alien and invasive species presence and impacts. The original versions of each country checklist (v1.0) undergo two potential types of updates: 1. Major updates: These happen when batches of new species or records become available, usually addressing multiple taxonomic groups simultaneously. Each checklist is assigned a new version number after a major update (e.g. from v1.0 to v2.0). 2. Incremental updates: These are smaller ongoing updates involving the addition of new species or records based on new publications as well as taxonomic or other updates. Incremental updates to a checklist are associated with a subversion number, e.g. v1.1. The checklist version number is visible/available on the citation.Taxonomic Coverages
