Compilations of costs of prevention and management of IAS in the EU
This report reviews available methodologies to assess and analyse the costs and benefits of relevance to IAS prevention and management, including economic, biodiversity, environmental, social and welfare considerations, measured in different currencies. It also proposes a database structure and a methodology to record in a standardised manner the information on costs and efficiency of measures targeting IAS, and a multi-criteria analysis method to assess different management alternatives. (Link to: report, costs, database)
