Rank ReasonsViola labradorica is a perennial herb in a variety of forests and widely distributed in northeastern North America, especially the Appalachian Mountains though extending southward and into boreal western North America, from Greenland and Newfoundland and Labrador to Northwest Territories in Canada, south to North Dakota, Georgia, Alabama and Florida in the United States. Threats include development, rights-of-way maintenance, logging, succession, recreational activities (especially off-road vehicles), and invasive species. 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 CommentsViola labradorica is widely distributed in northeastern North America, especially the Appalachian Mountains though extending southward and north and northwestward into boreal western North America, Greenland and Newfoundland and Labrador to Northwest Territories in Canada, south to North Dakota, Georgia and Alabama, and slightly disjunct in southwestern Georgia and the panhandle of Florida in the United States (Ballard et al. 2023). Range extent was estimated to be over 7 million square kilometers using herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1983 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 1983 and 2024, it is estimated that there are almost 1,800 occurrences rangewide (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Threat Impact CommentsAlthough threats are not widely documented, this species is threatened by development, rights-of-way maintenance, logging, succession, recreational activities (especially off-road vehicles), invasive species, and other threats in some places (NatureServe 2024). However, their overall impact is likely negligible given the species' broad range, large number of occurrences, and no obvious intrinsic vulnerabilities.
