Based on years of experience and the latest science, APHIS developed a list of 59 pests and diseases that could pose a significant risk to U.S. food and agriculture resources. The list is not meant to be all-encompassing, but rather focus on the most impactful pests and diseases. USDA's goal remains to keep the U.S. free of these foreign pests and diseases.

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, Hawaii, and the conterminous United States. Each list 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. 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).
