Rank ReasonsMenispermum canadense is a perennial vine occurring in deciduous woods, streambanks, hillsides, and along fencerows of eastern North America from Manitoba east to Quebec, Canada, and New Hampshire south to Florida, west to Texas, and north to North Dakota in the United States. There are an estimated 3,000 occurrences of this species, which are threatened by logging, development, recreational activities, rights-of-way maintenance, and other threats in some places. Little is known about trends, but with a large range extent, a high number of occurrences, abundant habitat, broad habitat preferences, and no obvious intrinsic vulnerabilities, Menispermum canadense is considered secure.
Range Extent CommentsMenispermum canadense occurs in eastern North America from Manitoba east to Quebec, Canada, and New Hampshire south to Florida, west to Texas, and north to North Dakota in the United States (FNA 1997). Range extent was estimated to be over 4.4 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 over 3,000 occurrences rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact CommentsAlthough threats are not widely documented, Menispermum canadense is threatened by logging, development, recreational activities, rights-of-way maintenance, 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 2024).
