Species-specific model estimates for where extra-range observations likely representing natural range expansions occur. We also include a map for each species showing intra-range observations, and extra-range observations colored by whether or not they are a) likely to represent natural range expansions, b) likely to represent introductions or vagrant individuals, or c) are flagged in iNaturalist as introduced but otherwise would have been classified as a natural range expansion.
