Titre : Salvinia plants in trade: what species are we actually talking about? Type de document : Imprimé Auteurs : Johannes Leonardus Cornelis Hendrikus van Valkenburg (1964) ; Laurens F. Piet ; Edu Boer Année de publication : 2023 Article en page(s) : 108-116 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Salvinia molesta D.S. Mitch. Résumé : Il est commun que l’étiquetage des plantes dans le commerce soit erroné et que des erreurs d'identification soient faites. Ainsi, dans le commerce, de nombreuses dénominations sont utilisés pour la plante aquatique ornementale connue sous le nom de salvinie géante ('Kariba weed'), mais rarement le nom scientifique correct Salvinia molesta Mitch. Pour les services d'inspection des pays membres de l'OEPP, l'identification correcte de S. molesta est devenue importante depuis que l'espèce a été ajoutée à la Liste A2 de l'OEPP et à la Liste des espèces exotiques envahissantes préoccupantes pour l’Union [Européenne] conformément au règlement UE 1143/2014, sur la base d'une analyse de risque phytosanitaire de l'OEPP pour cette espèce. Des inspections et une ne prospection ciblée sur les plantes de Salvinia dans le commerce aux Pays-Bas ont été réalisées et du matériel supplémentaire a été obtenu à partir de sources sauvages en Afrique du Sud, en Hongrie et aux États-Unis. L'identification des spécimens a été vérifiée par comparaison avec la collection de l'herbier du Centre de Biodiversité Naturalis de Leiden et avec les séquences de la base de données GenBank du NCBI. Cet article fournit les outils nécessaires pour identifier correctement les espèces de Salvinia concernées.

Titre : The EPPO prioritization process for invasive alien plants Type de document : Numérique Auteurs : Sarah Brunel ; Étienne Branquart ; Guillaume Fried ; Johannes Leonardus Cornelis Hendrikus van Valkenburg (1964) ; Giuseppe Brundu ; Uwe Starfinger ; S Buholzer ; A. Uludag ; M. Joseffson ; R. Baker Année de publication : 2010 Article en page(s) : 407-422 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Résumé : Although invasive alien plants are gaining increased attention within EPPO countries, there is no existing widely agreed method to identify those alien plants that are considered invasive and represent the highest priority for pest risk analysis. In the framework of the ad hoc Panel on Invasive Alien Species, EPPO proposes a prioritization process for invasive alien plants designed (i) to produce a list of invasive alien plants that are established or could potentially establish in the EPPO region and (ii) to determine which of these have the highest priority for an EPPO pest risk analysis. The process consists of compiling available information on alien plants according to pre-determined criteria, and can be run at the EPPO region level, or at a country or local area level. These criteria examine whether the species is alien in the area under study, and whether it is established or not. The criteria used primarily rely on observations in the EPPO region but, if the species is not established, the invasive behaviour of the species in other countries should be investigated, as well as the suitability of the ecoclimatic conditions in the area under consideration. The spread potential, the potential negative impacts on native species, habitats and ecosystems, as well as on agriculture, horticulture or forestry are considered. If the species qualifies as an invasive alien plant of major concern through this first set of questions, the process then investigates the efficiency of international measures (to be justified through a pest risk analysis) to prevent the entry and spread of the species. The second set of questions are designed to determine whether the species is internationally traded or enters new countries through international pathways for which the risk of introduction is superior to natural spread, and whether the species still has a significant suitable area for further spread. If used by several EPPO countries, this prioritization process represents an opportunity to provide consistent country lists of invasive alien plant species, as well as a tool for dialogue and exchange of information.

Titre : The large Gunnera’s (G. tinctoria and G. manicata) in Europe in relation to EU regulation 1143/2014 Type de document : Imprimé Auteurs : Johannes Leonardus Cornelis Hendrikus van Valkenburg (1964) ; Bruce A. Osborne ; Marcel Westenberg Année de publication : 2023 Article en page(s) : e0284665 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Résumé : Incorrect labelling of plants in the horticultural trade and misidentification is widespread. For the inspection services of the EU member states, correct identification of G. tinctoria has become important since the species was added to the List of Union concern in accordance with EU regulation 1143/2014 in August 2017. In the horticultural trade Gunnera plants are generally of modest dimensions and rarely flowering, so that the major distinguishing morphological characters for the identification of the two large species, G. tinctoria and G. manicata, are missing. As G. tinctoria is included in the EU regulation, its trade is prohibited, although the closely related species, G. manicata is not included on the list. Given that it is often difficult to distinguish between these two large herbaceous species using morphological attributes we used standard chloroplast DNA barcode markers, supplemented at a later stage by ITS markers. Plant material of putative G. tinctoria or G. manicata was obtained from the native and introduced range, both from “wild” sources, botanical gardens, and the horticultural trade. In western Europe plants circulating in the horticultural trade turned out to be predominantly G. tinctoria, with only one plant in cultivation identified as true G. manicata and the G. manicata found in botanical gardens was a hybrid recently described as G. x cryptica.

Mill Année de publication : 2020 Article en page(s) : 6235-6250 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Résumé : Prioritizing the management of invasive alien species (IAS) is of global importance and within Europe integral to the EU IAS regulation. To prioritize management effectively, the risks posed by IAS need to be assessed, but so too does the feasibility of their management. While the risk of IAS to the EU has been assessed, the feasibility of management has not. We assessed the feasibility of eradicating 60 new (not yet established) and 35 emerging (established with limited distribution) species that pose a threat to the EU, as identified by horizon scanning. The assessment was carried out by 34 experts in invasion management from across Europe, applying the Non-Native Risk Management scheme to defined invasion scenarios and eradication strategies for each species, assessing the feasibility of eradication using seven key risk management criteria. Management priorities were identified by combining scores for risk (derived from horizon scanning) and feasibility of eradication. The results show eradication feasibility score and risk score were not correlated, indicating that risk management criteria evaluate different information than risk assessment. In all, 17 new species were identified as particularly high priorities for eradication should they establish in the future, whereas 14 emerging species were identified as priorities for eradication now. A number of species considered highest priority for eradication were terrestrial vertebrates, a group that has been the focus of a number of eradication attempts in Europe. However, eradication priorities also included a diverse range of other taxa (plants, invertebrates and fish) suggesting there is scope to broaden the taxonomic range of attempted eradication in Europe. We demonstrate that broad scale structured assessments of management feasibility can help prioritize IAS for management. Such frameworks are needed to support evidence-based decision-making.
