Rank ReasonsSagittaria cuneata is an aquatic perennial monocot occurring in shallow waters and exposed substrates of rivers, lakes, ponds, meadows, and ditches of North America from Alaska and the Northwest Territories south through California, west to Texas, north to Nebraska, and east to New Jersey and Newfoundland and Labrador in the United States and Canada. There are over 1,000 occurrences estimated rangewide, which are threatened by development, water diversion, alteration of hydrology, erosion, succession, recreational activities, invasive species, livestock, drought, and other threats in some places, but with a large range extent, high number of occurrences, abundant habitat, broad habitat preferences, and no obvious intrinsic vulnerabilities, Sagittaria cuneata is considered secure.
Range Extent CommentsSagittaria cuneata occurs in North America from Alaska and the Northwest Territories south through California, west to Texas, north to Nebraska, and east to New Jersey and Newfoundland and Labrador in the United States and Canada (FNA 2000, Weakley and the Southeastern Flora Team 2024). Range extent was estimated using herbarium specimens, photo-based observations, and NatureServe Network occurrence data collected between 1994 and 2025 (GBIF 2025, iNaturalist 2025, NatureServe 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 more than 1,000 occurrences rangewide (GBIF 2025, iNaturalist 2025, NatureServe 2025, SEINet 2025).
Threat Impact CommentsAlthough threats are not widely documented, Sagittaria cuneata is threatened by development, water diversion, alteration of hydrology, erosion, succession, recreational activities, invasive species, livestock, drought, 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).
