Rank Reasons
Eleocharis palustris is found around the northern hemisphere in most of North America, northern Central America, Eurasia, and northern Africa. With a broad range, large number of occurrences, and a preference for widespread habitats, this species is considered secure.
Range Extent Comments
Eleocharis palustris is found around the northern hemisphere in most of North America, northern Central America, Eurasia, and northern Africa (FNA 2002, POWO 2025). Range extent was estimated using herbarium specimens and photo-based observations documented between 1994 and 2025 (GBIF 2025, iNaturalist 2025, RARECAT 2025, SEINet 2025).
Occurrences Comments
By applying a 1 km separation distance to herbarium specimens and photo-based observations documented between 1994 and 2025, it is estimated that there are thousands of occurrences rangewide (GBIF 2025, iNaturalist 2025, RARECAT 2025, SEINet 2025).
Threat Impact Comments
Although threats are not widely documented, Eleocharis palustris is potentially threatened by development, water management, invasive species, and other threats in some places. 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.
