Rank ReasonsDraba cana is a wide-ranging perennial herb occurring in northern North America from Greenland, Canada, and the United States, including northern New England, Michigan, Wisconsin, and Wyoming and South Dakota south to New Mexico and west. Threats include development, mining, roadside maintenance, succession, recreational activities, and invasive species. With a large range extent and number of occurrences, abundant habitat, broad habitat preferences, and no obvious intrinsic vulnerabilities, this species is considered secure.
Range Extent CommentsDraba cana occurs in northern North America from Greenland, Canada (except Nunavut), and the United States, including northern New England, Michigan, Wisconsin, and Wyoming and South Dakota south to New Mexico and west (FNA 2010).
Occurrences CommentsBy applying a 1 km separation distance to herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1983 and 2024, it is estimated that there are over 300 occurrences rangewide (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Threat Impact CommentsAlthough threats are not widely documented, this species is threatened by development, mining, roadside maintenance, succession, recreational activities, 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.
