Rank ReasonsCarex peckii is a wide-ranging perennial graminoid found in occurs in deciduous or mixed deciduous-coniferous woodlands, bases of slopes, or on exposed outcrops. It occurs in boreal North America from Alaska, United States, the Northwest Territories and British Columbia east to Nova Scotia, Canada, and south to New Jersey, Ohio, Michigan, Wisconsin, Iowa, Nebraska, and Colorado. There are over 500 estimated occurrences, which face threats from development, livestock grazing, recreational activities, 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.
Range Extent CommentsCarex peckii occurs in boreal North America from Alaska, United States, the Northwest Territories and British Columbia east to Nova Scotia, Canada, south to northern New Jersey, northern Ohio (possibly extirpated), southern Michigan, southern Wisconsin, eastern Iowa, Nebraska, and Colorado (FNA 2002, Weakley and the Southeastern Flora Team 2025). Range extent was estimated to be over 8 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 500 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, livestock grazing, recreational activities, 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, and affinity for typically abundant habitats.
