Carex pallescens

Carex pallescens is a wide-ranging perennial graminoid found in open meadows, grassy balds, and slopes. It occurs in eastern North America from Newfoundland Island and Nova Scotia west to Ontario, Canada, and south in the United States through New England to New Jersey west to Ohio, Michigan, Wisconsin, and Minnesota, disjunct in the mountains of Virginia, North Carolina, and Tennessee. There is some uncertainty as to its nativity in western North America in Montana, Washington, and perhaps Idaho and it is reported as introduced in British Columbia. It also occurs natively in Eurasia and introduced in New Zealand. There are thousands of occurrences worldwide, which face threats from development, gas well development, rights-of-way maintenance, recreational activities, succession, invasive species, and other threats in some places. Little is known about trends, but with a large range extent and large number of occurrences, abundant habitat, and broad habitat preferences, this species is considered secure.

Carex pallescens occurs in eastern North America from Newfoundland Island and Nova Scotia west to Ontario, Canada, and south in the United States through New England to New Jersey west to Ohio, Michigan, Wisconsin, and Minnesota, disjunct in the mountains of Virginia, North Carolina, and Tennessee, and with some uncertainty in western North America, reported as introduced in British Columbia and with uncertain nativity in Montana, Washington, and perhaps Idaho (FNA 2002, Giblin 2023, Montana Natural Heritage Program 2025, Weakley and the Southeastern Flora Team 2025). It also occurs natively in Eurasia and introduced in New Zealand (FNA 2002). Native range extent was estimated to be over 30 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).

By 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 thousands of occurrences rangewide (GBIF 2025, iNaturalist 2025, NatureServe 2025, RARECAT 2025, SEINet 2025).

Although threats are not widely documented, this species is threatened by development, gas well development, rights-of-way maintenance, recreational activities, succession, 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.
