Global Register of Introduced and Invasive Species - Liberia

The Global Register of Introduced and Invasive Species (GRIIS) presents validated and verified national checklists of introduced (alien) and invasive alien species at the country, territory, and associated island level.

Checklists are living entities, especially for biological invasions given the growing nature of the problem. GRIIS checklists are based on a published methodology and supported by the Integrated Publishing Tool that jointly enable ongoing improvements and updates to expand their taxonomic coverage and completeness.

Phase 1 of the project focused on developing validated and verified checklists of countries that are Party to the Convention on Biological Diversity (CBD). Phase 2 aimed to achieve global coverage including non-party countries and all overseas territories of countries, e.g. those of the Netherlands, France, and the United Kingdom.

All kingdoms of organisms occurring in all environments and systems are covered.

Checklists are reviewed and verified by networks of country or species experts. Verified checklists/ species records, as well as those under review, are presented on the online GRIIS website (www.griis.org) in addition to being published through the GBIF Integrated Publishing Tool.

全球引入及入侵物种登记册（GRIIS）呈现了经过验证和核实的国家引入（外来）和入侵外来物种的国家、领土及其相关岛屿名录。名录作为生物入侵问题日益严重背景下的动态实体，尤为重要。GRIIS名录基于已发表的方法论，并由集成出版工具支持，共同促进其分类覆盖范围和完整性的持续改进和更新。项目第一阶段着重于开发生物多样性公约（CBD）缔约国的验证和核实名录。第二阶段旨在实现全球覆盖，包括非缔约国以及所有国家的海外领土，例如荷兰、法国和联合王国的领土。所有环境与系统中出现的生物界的所有王国均被涵盖。名录由国家或物种专家网络进行审查和核实。经过核实的名录/物种记录，以及正在审查的记录，均在网上GRIIS网站（www.griis.org）展示，并可通过GBIF集成出版工具进行发布。
