Within LIFE RIPARIAS, there is a need for one or more field management registration systems that is fit for a variety of actors and species. Such a system should capture sufficient data to allow the evaluation of the cost-effectiveness of management actions and to perform the reporting to the EU for the Regulation. This project deliverable is a business analysis to explore and describe management registration systems of both LIFE RIPARIAS partners and other actors active in IAS management (regions, provinces, local authorities, NGOs). Based on this, potential solutions are qualitatively suggested. The analysis consists out of the following parts: Part I gives an overview of the different field management registration tools currently used within the LIFE RIPARIAS study area. Part II defines the needs of field managers towards registration of IAS. Part III compares field management registration software that are available on the market. Part IV explores the barriers to sharing data and investigates potential solutions for registering and reporting management data, This work was funded under the European Commission LIFE programme (LIFE19 NAT/BE/000953).

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.
