Rank ReasonsBarbarea orthoceras is a widespread perennial or biennial forb occurring in grasslands, sandbars, on scree, alpine meadows, ledges, forests, riparian zones, on railroad embankments, and in gravel pits in most of North America, as well as in Baja Mexico, and Asia. It is threatened by coal mining, recreational activities, livestock grazing, rights-of-way construction and maintenance, erosion, and likely other threats in some places. With a large range extent, over 1,000 occurrences, abundant habitat, broad habitat preferences, and no obvious intrinsic vulnerabilities, this species is considered secure.
Range Extent CommentsBarbarea orthoceras is widespread, occurring as a native species in most of North America, as well as in Baja Mexico, and Asia (POWO 2024). In North America, it is found from Alaska and the Northeast Territories east to Newfoundland, south to Massachusetts, through the northern Midwest, and New Mexico to California and north to Washington in the United States and Canada (FNA 2010). Range extent was estimated to be over 38 million square kilometers using herbarium specimens and photo-based observations collected between 1993 and 2024 (iNaturalist 2024, SEINet 2024).
Occurrences CommentsBy applying a 1 km separation distance to herbarium records and photo-based observations documented between 1993 and 2024, there are estimated to be over 1,400 occurrences rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact CommentsAlthough threats are not widely documented, Barbarea orthoceras is threatened by coal mining, recreational activities, livestock grazing, rights-of-way construction and maintenance, erosion, and likely other threats in some places, though there is insufficient data, including anecdotal accounts, to understand scope and severity of threats for this species (NatureServe 2024). However, their overall impact is likely negligible given the species' broad range, large number of occurrences, tolerance of light disturbance, and affinity for typically abundant habitats, as well as no obvious intrinsic vulnerabilities.
