Rank ReasonsCardamine concatenata is a perennial forb occurring in woodlands, forests, on limestone outcrops and cliffs, and rocky banks of eastern North America, from Manitoba and Quebec, Canada, south to Florida and Texas in the United States. There are over a thousand occurrences of this species rangewide, which are threatened by invasive species, recreation, logging, succession, rights-of-way construction and maintenance, trampling by livestock, and likely other threats in some places. Little is known about trends, but with a large range extent, abundant habitat, and broad habitat preferences, Cardamine concatenata is considered secure.
Range Extent CommentsCardamine concatenata occurs in eastern North America, from Manitoba and Quebec, Canada, south to Florida and Texas in the United States (FNA 2010). Range extent was estimated to be over 3.1 million square kilometers using herbarium specimens, photo-based observations, and NatureServe Network occurrence data collected 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 several thousand occurrences rangewide (GBIF 2025, iNaturalist 2025, NatureServe 2025, RARECAT 2025, SEINet 2025).
Threat Impact CommentsThreats to Cardamine concatenata are not well documented but include invasive species, recreation, logging, succession, rights-of-way construction and maintenance, trampling by livestock, and likely other threats in some places (NatureServe 2025). However, these threats are considered negligible given the broad range and large number of occurrences of the species.
