This USGS data release is ver. 2.0, 2022, of the database United States Register of Introduced and Invasive Species (US-RIIS). All versions of the US-RIIS database are available here: https://doi.org/10.5066/P92DN8D8. This version supersedes version 1.0 of the US-RIIS. The US-RIIS is derived from, and also supersedes, the USGS data release: "A comprehensive list of non-native species established in three major regions of the United States: Version 3.0" (https://doi.org/10.5066/P9E5K160). All three of the superseded/deprecated versions of this previous product are accessible here: https://doi.org/10.5066/P9E5K160.
