An increasing number of regulatory tools aiming to impose preventive and control actions against invasive species are currently being developed in Europe. Both species prioritization and the choice of best preventive and potential control actions to reduce the risk require robust and transparent riskassessment. Two different generic tools, available from http://ias.biodiversity.be, have recently been developed in Belgium to help decision makers reaching these goals, i.e. a quick screening prioritization process (Harmonia+) and a detailed risk assessment scheme. Both tools may be applied to any non-native organism irrespective its taxonomic affiliation and encompass an evaluation of the probability of organism entry, establishment, spread, and of the potential and magnitude of environmental, economic and social consequences including plant, animal and human health. Harmonia+ is a quick screening tool that may be used for different purposes (D’hondt et al. 2014): (i) the elaboration of priority lists of invasive species that are established or could potentially establish in an area, (ii) the fulfillment of rapid assessment to help conservation managers to prioritize actions when a new non-native organism is found in the wild and (iii) the identification of non-native specieswith the highest priority for in-depth and time consuming risk analyses and (iv) the scoring of probability and magnitude of the different elements included in those risk analyses. The detailed scheme for invasive species risk analysis is based on the recommendations of the international standards for pest risk analysis for organisms of quarantine concern produced by the Secretariat of the International Plant Protection Convention. It follows a process defined by two main stages, i.e. the risk assessment stage itself and the risk management stage, which involves identifying options for reducing the identified risks. This detailed analysis is especially valuable to know whether trade restrictions could be considered as adequate and efficient to reduce the risk. The output of the risk assessments based on these new tools will be presented and discussed for five emerging non-native species in Belgium (water primrose, red swamp crayfish, American bullfrog, sacred ibis and raccoon dog). Different recommendations and priorities for decision making will be provided for the different species based on the outcome of these analyses. Potential uses for the selection of species of EU concern in the framework of the new EC proposal ofRegulation on the prevention and management of the introduction and spread of IAS in Europe will also be discussed.

Impact ,risk assessment ,invasive species - Abstract
The sooner invasive alien species become tackled during invasion, the more cost-effective measures against them will be. But before such prevention or early eradication measures can take place, it is essential to have first identified those species posing the highest risks. Given the huge and still-increasing number of species that become transported and may become problematic, such a prioritization must allow for a high number of species from different taxonomic groups to be assessed in a relatively short time. For Belgium, Branquart (2007) launched a scheme that allowed for a quick screening of species' capacity to spread and impacts on the environment (ISEIA protocol). Yet, during the years, this scheme was found to unsatisfactorily cover several issues, and the challenge was therefore to refine this scheme further yet retain its simplicity. We therefore constructed Harmonia+, which -compared to its predecessor- is more complete with regard to the invasion stages covered, with the different kinds of impacts included, and with the consideration of pathogens, among other improvements. More specifically, Harmonia+ presents about 30 key questions on a particular organism, the answers of which need to be provided by one or more assessors. These questions refer to the species' risks on (1) introduction, (2) establishment, (3) spread and (4) impacts, the latter of which are further subdivided into impacts on (4a) environmental, (4b) plant, (4c) animal and (4d) human health. The answers are ordinally scaled, and this allows to put the (separate and combined) risks into scores, which in turn, allows to rank species and prioritize actions against them. Harmonia+ has come about through the collaboration of eight Belgian scientific institutes, each providing their expertise on different components of the protocol. A first version was tested by an international panel of risk analysis experts, and later versions have been applied to test cases by national experts as a means of validation (see Branquart et al., this volume). Harmonia+ can be consulted at http://ias.biodiversity.be.

INTRODUCED species ,BIOLOGICAL invasions ,BIODIVERSITY ,CONVENTION on Biological Diversity (1992) - Abstract
Abstract: Biological invasions are a threat to biodiversity, society and the economy. There is an urgent need to provide evidence‐based assessments of the risks posed by invasive alien species (IAS) to prioritize action. Risk assessments underpin IAS policies in many ways: informing legislation; providing justification of restrictions in trade or consumer activities; prioritizing surveillance and rapid response. There are benefits to ensuring consistency in content of IAS risk assessments globally, and this can be achieved by providing a framework of minimum standards as a checklist for quality assurance. From a review of existing risk assessment protocols, and with reference to the requirements of the EU Regulation on IAS (1143/2014) and international agreements including the World Trade Organisation, Convention on Biological Diversity and International Plant Protection Convention, coupled with consensus methods, we identified and agreed upon 14 minimum standards (attributes) a risk‐assessment scheme should include. The agreed minimum standards were as follows: (1) basic species description; (2) likelihood of invasion; (3) distribution, spread and impacts; (4) assessment of introduction pathways; (5) assessment of impacts on biodiversity and ecosystems; (6) Assessment of impact on ecosystem services; (7) assessment of socio‐economic impacts; (8) consideration of status (threatened or protected) of species or habitat under threat; (9) assessment of effects of future climate change; (10) completion possible even when there is a lack of information; (11) documents information sources; (12) provides a summary in a consistent and interpretable form; (13) includes uncertainty; (14) includes quality assurance. In deriving these minimum standards, gaps in knowledge required for completing risk assessments and the scope of existing risk assessment protocols were revealed, most notably in relation to assessing benefits, socio‐economic impacts and impacts on ecosystem services but also inclusion of consideration of climate change.
Policy implications . We provide a checklist of components that should be within invasive alien species risk assessments and recommendations to develop risk assessments to meet these proposed minimum standards. Although inspired by implementation of the European Union Regulation on invasive alien species, and as such developed specifically within a European context, the derived framework and minimum standards could be applied globally.

INTRODUCED species prevention ,INTRODUCED species ,BIODIVERSITY ,ECOSYSTEMS ,LAW - Abstract
Abstract: Effective prevention and control of invasive species generally relies on a comprehensive, coherent and representative list of species that enables resources to be used optimally. European Union (EU) Regulation 1143/2014 on invasive alien species (IAS) aims to control or eradicate priority species, and to manage pathways to prevent the introduction and establishment of new IAS; it applies to species considered of Union concern and subject to formal risk assessment. So far, 49 species have been listed but the criteria for selecting species for risk assessment have not been disclosed and were probably unsystematic. We developed a simple method to systematically rank IAS according to their maximum potential threat to biodiversity in the EU. We identified 1,323 species as potential candidates for listing, and evaluated them against their invasion stages and reported impacts, using information from databases and scientific literature. 900 species fitted the criteria for listing according to IAS Regulation. We prioritised 207 species for urgent risk assessment, 59 by 2018 and 148 by 2020, based on their potential to permanently damage native species or ecosystems; another 336 species were identified for a second phase (by 2025), to prevent or reverse their profound impacts on biodiversity; and a further 357 species for assessment by 2030.
Policy implications . We propose a systematic, proactive approach to selecting and prioritising IAS for risk assessment to assist European Union policy implementation. We assess an unprecedented number of species with potential to harm EU biodiversity using a simple methodology and recommend which species should be considered for risk assessment in a ranked order of priority along the timeline 2018–2030, based on their maximum reported impact and their invasion history in Europe.

- Abstract
Given the large number of alien species that may potentially develop into invasives, there is a clear need for robust schemes that allow to screen species for such risks. The Harmonia framework presented here brings together 30 questions that refer to distinct components of invasion. Together, they cover the stages of introduction, establishment, spread, and multiple kinds of impacts, viz. referring to the health of the environment (including wild species), cultivated plants, domesticated animals and man. In a complete assessment, input is provided by choosing among predefined ordinal answers and by supplementing these with textual clarification. Uncertainty is covered by indicating levels of confidence. By converting answers into scores, which are then condensed into summary statistics, Harmonia allows for quantitative output on stage-specific and general risks. Test assessments on five species emerging in Belgium showed the perceived environmental risks of Procambarus clarkii to be highest (0.72), and that of Threskiornis aethiopicus to be lowest (0.13). Given the considerable parallels that exist between invasive alien species and emerging infectious diseases, we additionally created Pandora, which is a risk analysis scheme for pathogens and parasites. It consists of 13 key questions and has the same structure as Harmonia. Since diseases play a paramount role in biological invasions, results of Pandora assessments may feed into Harmonia through a slightly adapted, host-specific version named Pandora. Harmonia, Pandora and Pandora may be used both for prioritization purposes and for underpinning detailed risk analyses, and can be consulted online through . [ABSTRACT FROM AUTHOR]
