Rank ReasonsEpilobium anagallidifolium is a perennial forb occurring on moist flats, coastal marsh edges, high montane and alpine habitats, and seeps worldwide, in North America, Greenland, Europe, Russia, China, and Japan. In North America, this species is found from Yukon east to Nunavut, Quebec, and Newfoundland Island, Canada, south to New Hampshire, and from Alaska south to California, Utah, and Colorado in the United States. There are several thousand estimated occurrences of this taxon rangewide, which are likely threatened by development, water diversion, alteration of hydrology, erosion, recreational activities, invasive species, and other threats in some places. Little is known about threats and trends, but with a large range extent and high number of occurrences, Epilobium anagallidifolium is considered secure.
Range Extent CommentsEpilobium anagallidifolium occurs globally in North America, Greenland, Europe, Russia, China, and Japan (FNA 2021). In North America, this species is found from Yukon east to Nunavut, Quebec, and Newfoundland Island, Canada, south to New Hampshire, and from Alaska south to California, Utah, and Colorado in the United States. The range extent was estimated to be over 71 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 CommentsAlthough threats are not widely documented, Epilobium anagallidifolium is potentially threatened by development, water diversion, alteration of hydrology, erosion, recreational activities, invasive species, and other threats in some places. However, their overall impact is likely negligible given the species' broad range and large number of occurrences.
