Rank ReasonsCommon Greenbrier (Smilax rotundifolia) occurs in eastern North America, from central Texas and Oklahoma, to central Missouri, southwestern Michigan, to northern Florida, and northeast to southern New Hampshire and southern Maine in the United States, and southern Ontario and Nova Scotia in Canada. In the southern and eastern United States, it occurs on many conservation lands, including National Forests, National Park Service lands, National Wildlife Refuges, State Forests, State Parks, and State Wildlife Management Areas. The fragmentation and loss of habitat is a threat, associated with residential development and urbanization.
Range Extent CommentsCommon Greenbrier (Smilax rotundifolia) occurs in eastern North America, from central Texas and Oklahoma, to central Missouri, southwestern Michigan, to northern Florida, and northeast to southern New Hampshire and southern Maine in the United States, and southern Ontario and Nova Scotia in Canada. Range extent was estimated to be 3.0 million square kilometers using herbarium specimens and photo-based observations documented between 1993 and 2024 (Flora of North America Editorial Committee 2002, GBIF 2024, iNaturalist 2024).
Occurrences CommentsBy applying a 1 km separation distance to herbarium records and photo-based observations documented between 1993 and 2024, it is estimated that there are more than 300 occurrences rangewide (GBIF 2024, iNaturalist 2024).
Threat Impact CommentsThe fragmentation and loss of habitat is a threat, associated with residential development and urbanization.
