Introduced (non-native) species that become 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, https://doi.org/10.5066/P95XL09Q), as of 2021-11-08, is comprised of three lists, for the localities of Alaska (AK, with 532 records), Hawaii (HI, with 6,075 records), and the conterminous United States (L48, with 8,657 records). Each 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. Each record has information on taxonomy, dates of introduction (where available; currently for 38% of the records), invasion status (invasive or introduced), and citations for the authoritative sources from which this information is drawn. 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, https://doi.org/10.5066/p9e5k160). There are 15,264 records in the master list and 12,981 unique names. The list is derived from 5,951 authoritative sources, was reviewed by or based on input from 30 invasive species scientists, and continues to be updated. Publication of version 2.0 of the US-RIIS is anticipated (but not guaranteed) in approximately 12 months.

The dataset catalogs and describes existing online, federally supported databases and tools dealing with various aspects of a potential national Early Detection and Rapid Response (EDRR) invasive species framework. This dataset is supplementary material 2 and 3 to the manuscript, "Envisioning a national invasive species information framework" (Reaser et al., 2020) published as part of a special open source issue dealing with invasive species early detection and rapid response by the journal Biological Invasions, Volume 22, Issue 1, January 2020 (https://link.springer.com/journal/10530/22/1). A user-friendly version of this dataset is also available online as a USGS Library Guide, here: https://libraryguides.usgs.gov/edrrinvasive

The Pacific Island Inventory and Monitoring Network (PACN) collected data on the status of established invasive plant species in the mangrove community of American Memorial Park (AMME), in the wet forest and subalpine plant communities of Hawaiʻi Volcanoes National Park (HAVO) and Haleakalā National Park (HALE), and in the wet forests and coastal community of Kalaupapa National Historical Park (KALA). Specifically, crews collected data on nonnative species richness, frequency and cover along 250, 500 and 1,000 meter long belt transects.
