Rank Reasons
Cerastium nutans is a wide ranging annual herb occurring across much of the United States, Canada, and Mexico. With a large range extent, more than 250 occurrences, abundant habitat, broad habitat preferences, and no obvious intrinsic vulnerabilities, this species is considered secure.
Range Extent Comments
Cerastium nutans is native to much of North America and parts of northwestern South America. It is also introduced in scattered areas of Europe. Range extent was estimated using herbarium specimens and photo-based observations documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, SEINet 2024).
Occurrences Comments
By applying a 1 km separation distance to herbarium records and photo-based observations documented between 1993 and 2024, there are estimated to be more than 250 occurrences rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact Comments
Although threats are not widely documented, Cerastium nutans is potentially threatened by development, road maintenance, invasive species, and other threats in some places. 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.
Ecology & Habitat

Habitat

Cerastium nutans occupies a wide variety of habitats across its range. It can be found in moist woods, stream banks, meadows, shores, rock ledges, boggy places, cultivated land, desert washes, ponderosa pine woodlands, and among rocks in uplands (FNA 2005).
