1. Biodiversity is changing at unprecedented rates, and it is increasingly important that these changes are quantified through monitoring programmes. Previous recommendations for developing or enhancing these programmes focus either on the end goals, that is the intended use of the data, or on how these goals are achieved, for example through volunteer involvement in citizen science, but not both. These recommendations are rarely prioritized. 2. We used a collaborative approach, involving 52 experts in biodiversity monitoring in the UK, to develop a list of attributes of relevance to any biodiversity monitoring programme and to order these attributes by their priority. We also ranked the attributes according to their importance in monitoring biodiversity in the UK. Experts involved included data users, funders, programme organizers and participants in data collection. They covered expertise in a wide range of taxa. 3. We developed a final list of 25 attributes of biodiversity monitoring schemes, ordered from the most elemental (those essential for monitoring schemes; e.g. articulate the objectives and gain sufficient participants) to the most aspirational (e.g. electronic data capture in the field, reporting change annually). This ordered list is a practical framework which can be used to support the development of monitoring programmes. 4. People's ranking of attributes revealed a difference between those who considered attributes with benefits to end users to be most important (e.g. people from governmental organizations) and those who considered attributes with greatest benefit to participants to be most important (e.g. people involved with volunteer biological recording schemes). This reveals a distinction between focussing on aims and the pragmatism in achieving those aims. 5. Synthesis and applications. The ordered list of attributes developed in this study will assist in prioritizing resources to develop biodiversity monitoring programmes (including citizen science). The potential conflict between end users of data and participants in data collection that we discovered should be addressed by involving the diversity of stakeholders at all stages of programme development. This will maximize the chance of successfully achieving the goals of biodiversity monitoring programmes.

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

The European Union Regulation (EU) 1143/2014 on invasive alien species (IAS) establishes an EU-wide framework for action to prevent, minimise and mitigate the adverse impacts of IAS on biodiversity and centres around the development of a list of IAS of EU Concern. The initial list of IAS of EU concern will be based on available risk assessments compliant with agreed minimum standards but horizon scanning is seen as critical to inform future updating of the list, in order to prioritise the most threatening new and emerging IAS. A workshop was held with the overarching aim of reviewing and validating an approach to horizon scanning to derive a ranked list of IAS which are likely to arrive, establish, spread and have an impact on biodiversity or related ecosystem services in the EU over the next decade. The agreed horizon scanning approach involved two distinct phases: i) Preliminary consultation between experts within five thematic groups to derive initial scores; ii) Consensus-building across expert groups including extensive discussion on species rankings coupled with review and moderation of scores across groups. The outcome of the horizon scanning was a list of 95 species, including all taxa (except microorganisms) within marine, terrestrial and freshwater environments, considered as very high or high priority for risk assessment ; Le Règlement de l'Union Européenne (UE) 1143/2014 sur les espèces notices envahissantes (EEE) établit un cadre d'actions à l'échelle européenne pour prévenir, réduire au minimum et atténuer les impacts négatifs des EEE sur la biodiversité, et se concentre sur le développement d'une liste d'EEE de préoccupation européenne. La liste initiale d'EEE de préoccupation européenne est basée sur les analyses de risque disponibles conformes aux standards minimums reconnus. Mais l'horizon scanning est essentiel pour informer les mises à jour futures de la liste, dans le but de prioritiser les EEE nouvelles et émergentes les plus menaçantes. Un workshop a été organisé avec pour but général ...
