All versions of the United States Register of Introduced and Invasive Species (US-RIIS) are based on a prior dataset that began to be complied in 2012, A comprehensive list of non-native species established in three major regions of the United States, which has 3 superseded versions, all of which are accessible on ScienceBase at https://doi.org/10.5066/P9E5K160. Over the years the content of the US-RIIS has been expanded to more closely comply with the Global Register of Introduced and Invasive Species initiative (https://www.griis.org) and to be compatible with Darwin Core's biodiversity data standards (https://dwc.tdwg.org/) in order to be shared as three subregional species checklist and occurrence datasets with the Global Biodiversity Information Faciity (https://www.gbif.org).
