Watch list Reptiles

Reptiles on the Natural Heritage Inventory's "watch list." Watch list species have experienced, or are believed to have experienced, a statewide or range-wide decline, but are not currently tracked in the Natural Heritage Inventory (NHI) database. The watch list includes newly discovered species for which origin and rarity need to be determined, certain animals designated as Species of Greatest Conservation Need (SGCN) in the Wisconsin Wildlife Action Plan, and species that were tracked in the past but proved more abundant, widespread, or less vulnerable than previously thought. Although watch list species are not actively tracked by NHI, occurrences documented during surveys are often stored by NHI, as these species could be tracked in the future if there is further evidence of their decline.
Scientific Name Common Name Global
Diadophis punctatus edwardsii Northern Ring-necked Snake G5T5 S3 SC/H
Heterodon platirhinos Eastern Hog-nosed Snake G5 S3S4 SC/H
Plestiodon fasciatus Common Five-lined Skink G5 S3S4 SC/H
