Rank ReasonsSibbaldiopsis tridentata is a perennial forb occurring in alpine tundra, grasslands, and woodlands on rocky and gravely shores, on rocky outcrops, and montane balds of North America and Greenland from Nunavut and the Northwest Territories east to Newfoundland and Labrador, south to Georgia, west to Tennessee and Iowa, and north to North Dakota in the United States and Canada. There are over 1,500 occurrences of this species, which are threatened by trampling and succession. 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, Sibbaldiopsis tridentata is considered secure.
Range Extent CommentsSibbaldiopsis tridentata occurs in North America and Greenland from Nunavut and the Northwest Territories east to Newfoundland and Labrador, south to Georgia, west to Tennessee and Iowa, and north to North Dakota in the United States and Canada (FNA 2014). Range extent was estimated using herbarium specimens, photo-based observations, and NatureServe Network occurrence data collected between 1993 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 1993 and 2024, it is estimated that there are more than 1,500 occurrences rangewide (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Threat Impact CommentsSibbaldiopsis tridentata is generally secure in high elevations in the southern portion of its range, though some populations may be impacted by trampling by humans (Southern Appalachian Species Viability Project 2002). Lack of disturbance leading to succession may also be a factor, as it needs open habitat.
