Rank ReasonsWhite Wood-aster (Eurybia divaricata) occurs in eastern North America in the Appalachian region, in the United States from Alabama, Georgia and Tennessee to southern Maine and in Canada in southern Ontario and Quebec. Threats to White Wood-aster include loss of habitat due to residential development and competition from invasive exotic plants. It is estimated that there are more than 300 (nearly 3000) occurrences rangewide, including on various National Forests, National Parks, State Forests, State Parks and other conservation lands in the eastern United States.
Range Extent CommentsWhite Wood-aster (Eurybia divaricata) occurs in eastern North America in the Appalachian region, in the United States from Alabama, Georgia and Tennessee to southern Maine and in Canada in southern Ontario and Quebec. Range extent was estimated to be 1.1 million square kilometers, using herbarium specimens and photo-based observations documented between 1993 and 2024 (Flora of North America Editorial Committee 2006, GBIF 2024, iNaturalist 2024, Weakley and Southeastern Flora Team 2023).
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 (nearly 3000) occurrences of White Wood-aster (Eurybia divaricata) rangewide (GBIF 2024, iNaturalist 2024).
