  • United States Register of Introduced and Invasive Species (US-RIIS)

    • Nov 4, 2022

    • DOI. United States Geological Survey.

    • Introduced (non-native) species that becomes established may eventually become invasive, so tracking introduced species provides a baseline for effective modeling of species trends and interactions, geospatially and temporally.

      The United States Register of Introduced and Invasive Species (US-RIIS) is comprised of three lists, one each for Alaska, Hawaii, and the conterminous United States. Each list includes introduced (non-native), established (reproducing) taxa that: are, or may become, invasive (harmful) in the locality; are not known to be harmful there; and/or have been used for biological control in the locality.

      To be included in the US-RIIS, a taxon must be non-native everywhere in the locality and established (reproducing) anywhere in the locality. Native pest species are not included. The US-RIIS builds on a previous dataset, A Comprehensive List of Non-Native Species Established in Three Major Regions of the U.S.: Version 3.0 (Simpson et al., 2020). An Open-File Report 2018-1156, 15 p., related to the predecessor of the US-RIIS: https://doi.org/10.3133/ofr20181156.

      Note: GBIF-US was formerly hosted at BISON.USGS.gov. The existing BISON website was taken down on December 17, 2021 and users are now redirected to Species observations for the United States and U.S. Territories via the new pilot implementation of the Global Biodiversity Information Facility (GBIF-US) data portal.

    • This collection houses Australia's most accurate and detailed listing of weeds within Australia and provides descriptions of their status in each Australian jurisdiction, as well as information about their physical and biological characteristics, diagnostic features, impacts, management strategies and methods, distribution and links to key resource and documents.

  • World Flora Online (WFO) Plant List

    • World Flora Online.

    • The WFO Plant List is the most comprehensive and authoritative list of the world’s vascular plants (flowering plants, conifers, ferns and their allies) and bryophytes (mosses, hornworts and liverworts), maintained by the global community of taxonomic experts as a free and open access resource. The WFO Plant List was launched in May 2021 as a next generation replacement for The Plant List (not updated since 2013), recognizing the continuing need for a user-friendly, citable static list of all plant species.
