Rank ReasonsBorodinia canadensis is a wide-ranging biennial herb in a variety of habitats occurring in eastern and central North America from Ontario and Quebec, Canada south to the United States from Maine west to North Dakota and south to the Florida panhandle and Texas. Threats include development, livestock grazing, invasive species, logging, recreational activities, rights-of-way maintenance, and other threats in some places. Little is known about trends, but with a large range extent and large number of occurrences, abundant habitat, broad habitat preferences, and no obvious intrinsic vulnerabilities, this species is considered secure.
Range Extent CommentsBorodinia canadensis occurs in eastern and central North America from Ontario and Quebec, Canada south to the United States from Maine west to North Dakota and south to the Florida panhandle and Texas (FNA 2010, Weakley and the Southeastern Flora Team 2024). Range extent was estimated to be over 2.9 million square kilometers using herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1994 and 2025 (GBIF 2025, iNaturalist 2025, NatureServe 2025, SEINet 2025).
Occurrences CommentsBy applying a 1 km separation distance to herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1994 and 2025, it is estimated that there are over 300 occurrences rangewide (GBIF 2025, iNaturalist 2025, NatureServe 2025, SEINet 2025).
Threat Impact CommentsAlthough threats are not widely documented, this species is threatened by development, livestock grazing, invasive species, logging, recreational activities, rights-of-way maintenance, and other threats in some places (NatureServe 2025). There is insufficient data, including anecdotal accounts, to understand the scope and severity of threats for this taxon. However, their overall impact is likely negligible given the species' broad range, large number of occurrences, and no obvious intrinsic vulnerabilities.
