In its introduced range, Amelanchier lamarckii F.G. Schroed. thrives on sandy, acidic soil, especially in heathlands, in open woodlands, along forest edges and in urban areas. Juneberry is apomictic and breeds true from seed. Fruits are dispersed by birds over long distances. Juneberry populations are slowly expanding in Western European countries (Belgium, Germany, Great Britain) and reported to be locally invasive. Juneberry can reduce the development of ground vegetation but it rarely forms dense monospecific stands. Outcompetition of native species is considered as unlikely. Impact on native vegetation is poorly reported in the scientific literature (Branquart et al. 2012).

Status and distribution in Luxembourg

Distribution map of Amelanchier lamarckii F.G. Schroed. in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2019-12-13.

The first record of Amelanchier lamarckii in Luxembourg was found by Krippel & Scheer (2006: 10) between May 1999 and October 2004 on the western slope of Esch-sur-Sûre castle. The species is currently (2018) still present there (Krippel et al. 2019: 164). The next records date before 2008 and cannot be dated exactly as Welter et al. (2008: 62) list 4 undated locations.

In Luxembourg, juneberry is commonly planted as an ornamental tree, which is the case for the records of the species in the municipalities of Luxembourg City (Cents, Limpertsberg) and Hesperange (Welter et al. 2008: 62). In the municipality of Feulen, the species seems to be widely grown in gardens, squares and along streets (MNHNL 2000-).

Juneberry is a honey species born in Europe from a North American strain (Lambinon & Verloove 2012: 373).

Juneberry is an apomictic microspecies, and presumed to be of hybrid origin (A. laevis and either A. arborea or A. canadensis) and therefore under the rules of botanical nomenclature it would be known as Amelanchier × lamarckii (Wikipedia contributors 2019).

Risk assessment

ISEIA protocol

ISEIA protocol: C1 (1+2+2+1) (Ries et al. 2013: 18).

Harmonia+ protocol

Overall risk score 0,07 = (Overall Invasion score 0,57 x Overall Impact score 0,13) (Ries et al. in prep.).
