Rank Reasons
Schoenoplectus tabernaemontani is a perennial, wetland grass-like plant that grows throughout much of North America and around the world. With a large range extent, more than 2000 occurrences, abundant habitat, and broad habitat preferences, this species is considered secure.
Range Extent Comments
Schoenoplectus tabernaemontani is a cosmopolitan species found on every continent, including all of North America north of Mexico, except Arctic regions (FNA 2002). 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 records and photo-based observations documented between 1994 and 2025, there are estimated to be more than 2000 occurrences rangewide (GBIF 2025, iNaturalist 2025, RARECAT 2025, SEINet 2025).
Threat Impact Comments
Although threats are not widely documented, Schoenoplectus tabernaemontani 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.
Ecology & Habitat

Habitat

Schoenoplectus tabernaemontani grows in "fresh to brackish marshes, fens, bogs, lakes, stream banks and bars, pioneering in disturbed places, often emergent in water to 1 m [deep]" (FNA 2002).
