I'd like to highlight the need to separate the socio-economic impacts posed by a species, from those considerations arising from its management. Both need to be considered in a risk analysis if we are to rapidly prioritise species for management. This issue and associated classifications was discussed in the earlier forum thread on 'How can we classify the costs and benefits associated with IAS management'
In terms of the social impacts of species presence, Bacher et al (2017)conclude that attempts to quantify socio-economic impacts in monetary terms are unlikely to provide a useful basis for evaluating and comparing impacts of invasive alien taxa because they are notoriously difficult to measure, they are often context-dependent, and important aspects of human well-being are ignored. They identify
different constituents of human well-being may be affected: security; material and immaterial assets; health; and social, spiritual and cultural relationships. They go on to propose the SEICAT process,which provides a mechanism to assess each of these in turn.

A different approach is needed to assess the sociological impacts of management. In this case, Booy et al (2017) propose a method to assess the overall feasibility of management, with separate sub-categories covering effectiveness, practicality, social acceptability, wider environmental impact, and cost.

This combination of methods, assessing the social implications of a species as part of wider risk assessment, and the social acceptability of management as part of risk management, can be combined in a process of risk analysis. This combined approach allows the prioritisation of species and their management based on a rapid assessment in non-monetary terms. While more detailed economic cost-benefit analyses can be used to assess individual cases, we need rapid methods to prioritise action given the large number of species and invasions that we are currently experiencing
