Rank ReasonsClintonia borealis is a perennial forb occurring in coniferous, mixed, or deciduous woods and seepages of eastern North America, from Manitoba to Nova Scotia, Canada, south to Maine and Georgia, west to Tennessee, and north to Minnesota in the United States. There are over 3,000 occurrences of this species, which are threatened by rights-of-way maintenance, logging, invasive species, recreation (including off-road vehicle use), deer herbivory, and other threats in some places. Little is known about threats or trends, but with a large range extent, a high number of occurrences, abundant habitat, broad habitat preferences, and no obvious intrinsic vulnerabilities, Clintonia borealis is considered secure.
Range Extent CommentsClintonia borealis occurs in eastern North America, from Manitoba to Nova Scotia, Canada, south to Maine and Georgia, west to Tennessee, and north to Minnesota in the United States (FNA 2002). Range extent was estimated to be over 4 million square kilometers using herbarium specimens and photo-based observations documented between 1993 and 2024 (GBIF 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 3,000 occurrences rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact CommentsAlthough threats are not widely documented, Clintonia borealis is threatened by rights-of-way maintenance, logging, invasive species, recreation (including off-road vehicle use), deer herbivory, and other threats in some places (NatureServe 2024). 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, tolerance of light disturbance, and affinity for typically abundant habitats, as well as no obvious intrinsic vulnerabilities.
