Rank Reasons
Uvularia sessilifolia is a wide-ranging perennial forb in forests of eastern and central North America from Nova Scotia west to Manitoba, Canada south to Florida and Texas in the United States. Threats include development, logging, recreational activities, deer browsing, 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 Comments
Uvularia sessilifolia occurs in eastern and central North America from Nova Scotia west to Manitoba, Canada south to the Florida panhandle west to eastern Texas in the United States (FNA 2002, Weakley and the Southeastern Flora Team 2024). Range extent was estimated to be over 4.2 million square kilometers using herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Occurrences Comments
By applying a 1 km separation distance to herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1993 and 2024, it is estimated that there are over 4,000 occurrences rangewide (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Threat Impact Comments
Although threats are not widely documented, this species is potentially threatened by development, logging, recreational activities (especially off-road vehicles), deer browsing, invasive species, and other threats in some places. However, their overall impact is likely negligible given the species' broad range, large number of occurrences, and no obvious intrinsic vulnerabilities.
Ecology & Habitat

Habitat

Uvularia sessilifolia grows in moist hardwood coves and forests, on slopes, alluvial bottomlands, thickets, and xeric woods northwards (FNA 2002, Weakley and the Southeastern Flora Team 2024).
