Rank ReasonsSenna hebecarpa is a wide-ranging perennial herb in open wet habitats occurring in eastern North America from Ontario, Canada and in the United States from Maine and New Hampshire west to Wisconsin and south to Georgia and Alabama. Threats include development, succession, rights-of-way maintenance activities, recreational activities, and invasive species. Little is known about trends, but with a large range extent and over 650 occurrences, this species is considered secure.
Range Extent CommentsSenna hebecarpa occurs in eastern North America from Ontario, Canada and in the United States from Maine and southern New Hampshire west to southern Wisconsin and south to Georgia and Alabama. Range extent was estimated to be almost 1.8 million square kilometers using herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Occurrences CommentsBy applying a 1 km separation distance to herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1993 and 2024, it is estimated that there are over 650 occurrences rangewide (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Threat Impact CommentsAlthough threats are not widely documented, Senna hebecarpa is threatened by development, succession, rights-of-way maintenance activities, recreational activities (especially off-road vehicles), invasive species, and other threats in some places, though there is insufficient data, including anecdotal accounts, to understand scope and severity of threats for this species.
