Increasing status of non-native vascular plants in the Sefton Coast sand-dune system, north Merseyside, UK / Philip Howard Smith in British & Irish Botany, vol. 2, n°2 (Année 2020)

Between 2005/06 and 2018, twice as many non-native as native plants were found. An analysis of occurrences of native and non-native taxa in six major habitat types found that a higher proportion of aliens was present in scrub/woodland and disturbed ground, while native plants had more occurrences in fixed dunes/dune grasslands, dune heath and wetlands. No differences between the two groups were detected for strandline/shingle and embryo/mobile dune habitats. Twenty-four non-native and 14 native taxa showed invasive characteristics in the duneland. The former included especially Hippophae rhamnoides and Rosa rugosa, both constituting major threats to sand-dune biodiversity. Particularly invasive native plants were Arrhenatherum elatius, Betula spp., Salix cinerea, and Ulex europaea. The main findings accord with studies elsewhere in Britain and Europe showing recent increases of neophytes in semi-natural habitats and that both non-native and native species can have invasive traits. The open habitats of coastal dunes seem to be particularly susceptible to plant invasions."

Species of Cotoneaster (Rosaceae, Maloideae) indigenous to, naturalising or commonly cultivated in Central Europe / Bernhard Dickoré in Willdenowia, vol. 40, n°1 (Année 2010)  

Public [article]  inWilldenowia > vol. 40, n°1 (Année 2010) . - pp. 13-45 Titre : Species of Cotoneaster (Rosaceae, Maloideae) indigenous to, naturalising or commonly cultivated in Central Europe Type de document : texte imprimé Auteurs : Bernhard Dickoré, Auteur ; Kasperek Gerwin, Auteur Année de publication : 2010 Article en page(s) : pp. 13-45 Langues : Allemand (ger) Catégories : [ZG] Chine [Espèces (in biblio)] Cotoneaster [Thèmes] Plantes ornementales [Thèmes] Taxonomie Mots-clés : néophyte Résumé : "Several alien species of the Eurasian genus Cotoneaster are naturalising in Central Europe, apparently increasingly so, and some on a massive scale. They presumably originate from large-scale cultivation for ground cover, hedges or as ornamental shrubs. The present paper keys and synopses the Cotoneaster species indigenous to, naturalising or commonly cultivated in Central Europe, on the basis of, relatively limited, both living (wild, adventive and cultivated) and herbarium material. An attempt is made to understand the nature of variation from the genus' centre of diversification, the mountains of China and the Himalayas, which are likewise the origin of most cultivated and naturalising Cotoneaster species. Taxonomic and nomenclatural problems, putatively relating to the presence of apomixis and hybridization in the genus, are discussed. Many of the more than 500 published binomials, including a substantial proportion of those based on cultivated material, seem to be poorly defined, both morphologically and chorologically. Of an estimated total of only 50-70 Cotoneaster species worldwide, about 20, mainly chinese species have been found escaping from cultivation in Central Europe. Presently, about ten species must be considered fully naturalised and, locally at least, invasive."
