Titre : Reproduction of Crassula helmsii by seed in western Europe Type de document : Électronique Auteurs : Bram D'hondt ; Luc Denys ; Wim Jambon ; Roeland De Wilde ; Tim Ardiaens ; Jo Packet ; Johannes Leonardus Cornelis Hendrikus van Valkenburg (1964) Année de publication : 2016 Article en page(s) : 125-130 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Crassula helmsii (Kirk) Cockayne, 1907 Résumé : The amphibious plant species Crassula helmsii is a widely established and still-spreading alien in various parts of Europe, where it is considered invasive as its dense swards stress the viability of local biota. The species was considered to exclusively reproduce through vegetative means, until ex situ germination was recorded from a single locality in Belgium. We assessed whether this seed viability holds on a wider scale, by testing 16 populations from The Netherlands, Belgium, northern France, eastern England and northern Germany in a greenhouse germination experiment. Seedlings were observed from all populations but two, and from each of the five countries. Although most fruits were lacking seeds and the inferred germination percentages were overall low, germinable seed numbers are considerable given the high density of flowering stems. An in situ test revealed seeds to make it through normal winter conditions without signs of physical damage and with retention of germinability. Our results suggest that reproduction by seed is a relatively cryptic but widespread phenomenon throughout western Europe. The persistency of seed banks requires further investigation. Nonetheless, these findings already challenge the efficacy of techniques currently applied in C. helmsii control.

Titre : A second population of Cabomba caroliniana Gray (Cabombaceae) in Belgium with options for its eradication Type de document : Électronique Auteurs : Kevin Scheers ; Luc Denys ; Jo Packet ; Tim Adriaens Année de publication : 2016 Article en page(s) : 227-232 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Cabomba caroliniana A.Gray, 1848 Résumé : We report a sizeable population of Carolina fanwort Cabomba caroliniana from Belgium. The new population was discovered in June 2013 and represents the only occurrence in the Atlantic region of this country. A previous record dates back to 1998 but by 2006 this population was eliminated unintentionally by dredging works. Cabomba caroliniana is expected to become a regulated invasive alien species of EU concern, in which case it will need to be eradicated. We briefly describe the site conditions, discuss possible measures for eradication and present a decision support scheme.
