Concept Reference: Kartesz, J.T. 1994. A synonymized checklist of the vascular flora of the United States, Canada, and Greenland. 2nd edition. 2 vols. Timber Press, Portland, OR.
Concept Reference Code: B94KAR01HQUS
Name Used in Concept Reference: Prunus alleghaniensis
Taxonomic Comments: Includes two varieties, var. alleghaniensis of the Appalachian region, and var. davisii of Michigan (Voss 1985). FNA (vol. 9, 2014) expands the concept of Prunus umbellata to include P. alleghaniensis, with associated varieties (alleghaniensis and davisii), while Kartesz (1994) treats them as distinct.

NatureServe Status

Global Status: G4
Global Status Last Reviewed: 03Oct2002
Global Status Last Changed: 03Nov1994
Rounded Global Status: G4 - Apparently Secure
Reasons: At present, population seems to be secure. However, it is not abundant (except in a few local areas) and has a fairly narrow range in two portions (mid-Appalachians and north-central Michigan).
Nation: United States
National Status: N4

NatureServe Global Conservation Status Factors

Range Extent Comments: NJ, mountains of central PA south to western MD, eastern WV, western VA, and northwestern NC. Also reported from northeastern TN, and MI (var. davisii). Historical record(s) from CT. Exotic in MA.

Number of Occurrences: 81 to >300
Number of Occurrences Comments: CD- Between 30-300 EOs in 7 states. Locally abundant in northern lower peninsula of Michigan, and in south-central Pennsylvania.

Population Size Comments: Has never been considered abundant except in PA where it may be locally abundant in sand barrens [field work needed to establish the validity of this]. Recent fieldwork in Michigan has shown this species (as var. davisii) to be locally abundant there as well. Found abundantly in portions of southwestern Virginia, 1994.

Overall Threat Impact Comments: A NJ population is threatened by roadside maintenance and housing developments. Defoliation by gypsy moths is often considerable in central and southcentral PA. Prunus alleghaniensis is rare throughout its range, making it especially vulnerable to land-use conversion, habitat fragmentation, and forest management practices (Southern Appalachian Species Viability Project 2002). In Michigan, succession as a result of fire suppression is a threat and herbiciding and construction threaten roadside populations (Higman and Penskar 1996).

Short-term Trend Comments: In Michigan, Prunus alleghaniensis (var. davisii) is declining, primarily because of loss of habitat (Higman and Penskar 1996).

Ecology & Life History
Help
Habitat Comments: In the main portion of its range, P. alleghaniensis occurs in dry rocky woods, in thickets, occasionally on shale and sand barrens, and along the borders of woods (Gleason & Cronquist 1991; Fernald 1950). Wight (1915) provides relatively little description of habitat, noting that this species occurred onlimestone bluffs, on sandy river bottoms along a river in Connecticut, in wet thickets, and in sandy soil along roadsides. In the disjunct portion of its range (Michigan), it occurs in jack pine barrens, open woodlands, and sandy plains (Voss 1985).
