Note: this dataset has been superseded by this new data product: Simpson, A., Turner, R., Blake, R., Liebhold, A., and Dorado, M., 2021, United States Register of Introduced and Invasive Species: U.S. Geological Survey data release, Invasive species are a subset of non-native (or nonindigenous) species, and knowing what species are non-native to a region is a first step to managing invasive species. This is the second update to the dataset "First comprehensive list of non-native species established in three major regions of the United States" supporting a USGS Open File Report by the same name published on 2018-10-17. Version 3.0 of the non-native species list, as of 2020-09-15, contains 13,391 [...]

This dataset builds on previous versions and accompanies the 2018 U.S. Geological Survey Open File Report of the same name. Its purpose is to inform policy makers and the public which non-native taxa are currently established (with reproducing populations) in Alaska, Hawaii, and the conterminous United States. Our intention, though not a guarantee, is that this national non-native species list will be continually and regularly updated with new information (including corrections), made publicly available online and in a machine-readable web service format, and be clearly labeled with a version number and release date.
