Taxonomic CommentsThis record is for the treatment of Amelanchier arborea in the narrow sense recognized in FNA (2014, vol. 9) which excludes A. arborea var. austromontana as indistinct from A. spicata. FNA also does not recognize A. arborea var. alabamensis as distinct from the typical species. The broader treatment recognized in Kartesz (1999) included var. austromontana and recognized var. alabamensis as distinct.

Rank ReasonsAmelanchier arborea is a large shrub or small tree which is common throughout the eastern United States and southern Canada. With a large range extent, more than 1,000 occurrences, abundant habitat, and broad habitat preferences, this species is considered secure.
Range Extent CommentsAmelanchier arborea is native to the eastern United States and southern Canada, from the eastern Great Plains to the Atlantic coast from Nova Scotia to Florida (FNA 2014). It is also planted as an ornamental in Europe. Range extent was estimated to be 4.5 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 1,000 occurrences rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact CommentsAlthough threats are not widely documented, Amelanchier arborea is potentially threatened by development, road maintenance, invasive species, and other threats in some places. However, their overall impact is likely negligible given the species' broad range, large number of occurrences, tolerance of light disturbance, and affinity for typically abundant habitats, as well as no obvious intrinsic vulnerabilities.
