Rank ReasonsCarex aurea is a perennial graminoid in a variety of open or shaded wetland habitats that occurs throughout Canada and in the United States in Alaska and Maine west through the Great Lakes region to Washington and south to Texas west to California. There are over 1800 occurrences, which face threats from development, quarrying, rights-of-way maintenance, recreational activities, hydrological alteration, 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 CommentsCarex aurea occurs throughout Canada and in the United States in Alaska and Maine west through the Great Lakes region to Washington and south to Texas west to California (FNA 2002). Range extent was estimated to be over 15 million square kilometers using herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1994 and 2025 (GBIF 2025, iNaturalist 2025, NatureServe 2025, RARECAT 2025, SEINet 2025).
Occurrences CommentsBy applying a 1 km separation distance to herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1994 and 2025, it is estimated that there are over 1800 occurrences rangewide (GBIF 2025, iNaturalist 2025, NatureServe 2025, RARECAT 2025, SEINet 2025).
Threat Impact CommentsAlthough threats are not widely documented, this species is threatened by development, quarrying, rights-of-way maintenance, recreational activities (especially off-road vehicles), hydrological alteration, invasive species, and other threats in some places, though there is insufficient data, including anecdotal accounts, to understand scope and severity of threats for this species (NatureServe 2025). 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.
