“…There have been a number of horizons scanning exercises for IAS in Europe, but these have usually involved one or few taxonomic groups, such as plants (Andreu & Vilà, ; Thomas, ) or animals (Parrott et al., ), or distinct environments such as freshwater (Gallardo & Aldridge, ), specific countries (Matthews et al., ; Roy, Peyton et al., ; Matthews et al., ), or regions (NOBANIS ; Gallardo et al., ). Most of these approaches have relied on information from the literature coupled with impact assessment frameworks (Parrott et al., ; Thomas, ) or modelling approaches (Gallardo & Aldridge, ).…”

The European Union (EU) has recently published its first list of invasive alien species (IAS) of EU concern to which current legislation must apply. The list comprises species known to pose great threats to biodiversity and needs to be maintained and updated. Horizon scanning is seen as critical to identify the most threatening potential IAS that do not yet occur in Europe to be subsequently risk assessed for future listing. Accordingly, we present a systematic consensus horizon scanning procedure to derive a ranked list of potential IAS likely to arrive, establish, spread and have an impact on biodiversity in the region over the next decade. The approach is unique in the continental scale examined, the breadth of taxonomic groups and environments considered, and the methods and data sources used. International experts were brought together to address five broad thematic groups of potential IAS. For each thematic group the experts first independently assembled lists of potential IAS not yet established in the EU but potentially threatening biodiversity if introduced. Experts were asked to score the species within their thematic group for their separate likelihoods of i) arrival, ii) establishment, iii) spread, and iv) magnitude of the potential negative impact on biodiversity within the EU. Experts then convened for a 2‐day workshop applying consensus methods to compile a ranked list of potential IAS. From an initial working list of 329 species, a list of 66 species not yet established in the EU that were considered to be very high (8 species), high (40 species) or medium (18 species) risk species was derived. Here, we present these species highlighting the potential negative impacts and the most likely biogeographic regions to be affected by these potential IAS.

“…Finally, frameworks can be incorporated in risk analyses (Kumschick et al 2020) and horizon-scanning exercises (Matthews et al 2014(Matthews et al , 2017Tsiamis et al 2020) to make predictions concerning future invaders and their pathways of introduction and to determine what can be done to prevent future introductions. Frameworks with detailed categories are likely to be most useful for this purpose and, indeed, the detailed sub-categories of the CBD framework have been used in horizon-scanning exercises (e.g.…”

Alien species are introduced to new regions in many different ways and for different purposes. A number of frameworks have been developed to group such pathways of introduction into discrete categories in order to improve our understanding of biological invasions, provide information for interventions that aim to prevent introductions, enable reporting to national and international organisations and facilitate the prediction of threats. The introduction pathway classification framework proposed by the Convention on Biological Diversity (CBD) as a global standard is comprised of six main categories and 44 sub-categories. However, issues have arisen with its implementation. In this position paper, we outline five desirable properties of an introduction pathway classification framework – it should be compatible (i.e. the level of detail of the categories is similar to that of the available data), actionable (i.e. categories link to specific interventions), general (i.e. categories are applicable across the contexts that are of interest (e.g. taxa, habitats and regions)), equivalent (i.e. categories are equivalent in their level of detail) and distinct (i.e. categories are discrete and easily distinguished) – termed the CAGED properties. The six main categories of the CBD framework have all of the CAGED properties, but the detailed sub-categories have few. Therefore, while the framework has been proposed by the CBD as a global standard and efforts have been made to put it into practice, we argue that there is room for improvement. We conclude by presenting scenarios for how the issues identified could be addressed, noting that a hybrid model might be most appropriate.

Data about floristic records of Ionoxalis tetraphylla (Cav.) J. Rose (Oxalis tetraphylla Cav.) (Oxalidaceae), a new alien species of Ukrainian flora were presented. Species has Central American origin, its primary area are covers Mexico, Panama, Guatemala, Costa Rica, Caribbean islands. Secondary area spreads on Europe, Asia and Australia. It was found in neighboring countries with Ukraine, including Russia and Belorussia. As a naturalized species it was tagged in some countries of Southern Europe. The main centers of species introduction in Ukraine are M.M. Hryshko National Botanical Garden of NAS of Ukraine, Acad. O.V. Fomin Botanical Garden of Taras Shevchenko Kyiv National University, Botanical Garden of Oles’ Honchar Dnipro National University, Botanical Garden of V.N. Karazin Kharkiv National University, Botanical Garden of V.I. Vernadsky Taurian National University, Syretskyi dendrological park (Kyiv), private gardens and greenery managements in Kyiv and Kyiv Region, Odesa, Kamyanets-Podilskyi (Khmelnytskyi Region) and other regions of the country. Information about spontaneously distribution of the plants in Ukraine nowdays is absent. At the first time some escaped plants of the I. tetraphylla were recorded in 2019 near village Dovzhyk of Zhymomyr District of Zhytomyr Region. Some individuals grew in old pine forest margins near path. Plants successfully overwintered at 2019/2020 years. Taxonomical and morphological characteristics, chorological data (primary and secondary areas) and ecological peculiarities are presented. According to the time of immigration this species is kenophyte, according to the way of introduction – ergasiophyte and according to the degree of naturalization in Ukraine it is ephemerophyte. The species is mesotroph, mesophyte, scio-heliophyte. In conditions of Ukraine it blooms profusely but almost never forms seeds, and reproduces vegetatively – by daughter bulbs. The map of the species distribution (spontaneously and in culture) in Ukraine is presented. Keywords: alien species, Ionoxalis tetraphylla, floristic record, Ukraine
