United States Register of Introduced and Invasive Species (US-RIIS) (THIS VERSION HAS BEEN SUPERSEDED by US-RIIS V2.0, November 2022, available at https://doi.org/10.5066/P9KFFTOD) Introduced (non-native) species that becomes established may eventually become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 (AK, with 532 records), Hawaii (HI, with 6,075 records), and the conterminous United States (L48, with 8,657 records). Each list includes introduced (non-native), established (reproducing) taxa that: are, or may become, invasive (harmful) in the locality; are...
