Rank Reasons
Calla palustris is a perennial herb with a circumpolar distribution where it occurs in northern regions of North America, Europe, and Asia.With a large range extent, thousands of occurrences, abundant habitat, and broad habitat preferences, this species is considered secure.
Range Extent Comments
Calla palustris has a circumpolar distribution where it occurs in northern regions of North America, Europe, and Asia. In North America, it occurs throughout Canada but extends as far south as Maryland, Pennsylvania, and Illinois. Range extent was estimated using herbarium specimens and photo-based observations documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, SEINet 2024).
Occurrences Comments
By applying a 1 km separation distance to herbarium records and photo-based observations documented between 1993 and 2024, there are thousands of occurrences rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact Comments
Calla palustris is threatened by succession, invasive species, alteration of hydrology, habitat alteration by beavers, recreation, logging, climate change, and other threats in some places (NatureServe 2024). There is insufficient data, including anecdotal accounts, to understand the scope and severity of threats for this taxon.
