Rank Reasons
Carex crinita is a wide-ranging perennial graminoid in a variety of wetlands occurring in eastern North America from Nova Scotia west to Manitoba, Canada and south in the United States to Georgia west to Texas. Its varieties may be sympatric and syntopic, and hybrids of them with other Carex species have been reported. Threats include development, rights-of-way maintenance, logging, hydrological alteration, succession, and invasive species. Little is known about trends, but with a large range extent and large number of occurrences, broad habitat preferences, and no obvious intrinsic vulnerabilities, this species is considered secure.
Range Extent Comments
Carex crinita occurs in eastern North America from Nova Scotia west to Manitoba, Canada and south in the United States to Georgia west to Texas (FNA 2002). See individual entries for distribution details about the varieties. Range extent was estimated to be over 5 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 1,000 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, rights-of-way maintenance, logging, hydrological alteration, succession, 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

Carex crinita grows in swamps, floodplain forests, wet forests, wet meadows, marshes, bogs, stream edges, margins of lakes and ponds, roadside ditches, and a wide range of other wetlands (FNA 2002, Weakley and the Southeastern Flora Team 2024).
