Rank ReasonsDitch-stonecrop (Penthorum sedoides) occurs in eastern North America, its native range is in Canada from New Brunswick to southeastern Manitoba, and in the United States from Maine to Florida, and west to eastern North Dakota to east Texas. There are estimated to be more than 2500 occurrences rangewide, including within various National Forests, in the Great Smoky Mountains National Park, and in various National Wildlife Refuges, State Parks, State Forests, and State Wildlife Management Areas. Threats include the loss of habitat due to residential development and urbanization, and alteration to wetlands including drainage and impoundment of streams associated with dam construction.
Range Extent CommentsDitch-stonecrop (Penthorum sedoides) occurs in eastern North America, in the eastern United States and southeastern Canada. Its native range is in Canada from New Brunswick to southeastern Manitoba, and in the United States from Maine to Florida, and west to eastern North Dakota to east Texas. It is introduced in southern British Columbia, Oregon, and Washington, where it grows in cranberry bogs (FNA 1997). The native range extent in eastern North America was estimated to be 4.8 million square kilometers, using herbarium specimens and photo-based observations documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, SEINet 2024).
Occurrences CommentsBy applying a 1 km separation distance to herbarium records and photo-based observations documented between 1993 and 2024, there are estimated to be more than 2500 occurrences rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact CommentsThreats to Ditch-stonecrop (Penthorum sedoides) include the loss of habitat due to residential development and urbanization, and alteration to wetlands including drainage and impoundment of streams associated with dam construction.
