Non‐native species continue to be introduced to the United States from other countries via trade and transportation, creating a growing need for early detection and rapid response to new invaders. It is therefore increasingly important to synthesize existing data on non‐native species abundance and distributions. However, no comprehensive analysis of existing data has been undertaken for non‐native species, and there have been few efforts to improve collaboration. We therefore conducted a survey to determine what datasets currently exist for non‐native species in the US from county, state, multi‐state region, national, and global scales. We identified 319 datasets and collected metadata for 79% of these. Through this study, we provide a better understanding of extant non‐native species datasets and identify data gaps (ie taxonomic, spatial, and temporal) to help guide future survey, research, and predictive modeling efforts.
