As one objective, natural scientists investigate the effects of invasive species on ecosystems and their functioning (Levine et al. 2003). However, impacts on ecosystems are also of relevance for society. Changes in ecosystems affect humans in so far as ecosystems provide goods and services, such as fresh water, food and fibbers or recreation, which might be altered due to invasive species. Therefore impacts of biological invasions should be an object of socio-economic interest, which is also demanded by the Convention on Biological Diversity (2002). The following chapter aims at providing elements for the analysis of impacts of invasive species from the socio-economic point of view. Such an analysis is politically relevant, since impacts are the focal point of every decision to establish a proper management regime. For an encompassing analysis an integrative framework is needed to structure the information on impacts. For that purpose, the concept of Ecosystem Services is introduced (see Sect (19.)2). Alternative decisions on the appropriate management of invasive species face trade-offs between outcomes and
