Taxonomic CommentsFNA (vol. 9, 2014) includes Crataegus engelmannii (= C. berberifolia var. engelmannii) as a variety of C. berberifolia, therefore according to FNA, Kartesz's (1994) C. berberifolia is equivalent to C. berberifolia var. berberifolia.

Rank ReasonsCrataegus berberifolia is endemic to the southeastern United States where it is most common in the western portion of its range. See each variety for more details. Threats to the species at large likely include habitat loss and succession, as well as impacts from fungal rusts. More information is needed about threats, trends, abundance, and distribution.
Range Extent CommentsCrataegus berberifolia is endemic to the southeastern United States. Crataegus berberifolia var. berberifolia occurs from Texas to Virginia on the Coastal Plain and Piedmont. Crataegus berberifolia var. engelmannii overlaps in range to some extent, but extends into the midwestern United States to the Interior Highlands, Interior Low Plateau, and the Appalachain Mountains (Weakley 2020). Both varieties are most common the western portion of the range, in Arkansas and Louisiana (Weakley 2020, FNA 2014b, Lance 2014).
Threat Impact CommentsLike most Crataegus, this species is susceptible to blight and fungal rusts which can cause stem cankers and dieback, as well as inhibit seed production. Fungal rusts are especially problematic when the alternate host, Eastern Red Cedar (Juniperus virginiana) (Lance 2014). Habitat loss and succession are likely threats in some areas.
