Engagement of different stakeholder groups in the management responses to the different stages of the invasion process of a generalised pest population infestation. Fig. 1 is a conceptual diagram intended to summarise how the various stakeholders interviewed in our survey position their involvement along the various stages of the invasion curve. The thickness of the bars is proportional to their relative involvement in these five steps. The six stakeholder groups were obtained by hierarchically clustering their responses to the questionnaire, assigning a generic name to the group, based on their reported profession. “Managers and Owners” The six stakeholder groups were obtained by grouping the respondents according to their declared professions. “Forest managers” are responsible for the management or maintenance of forests. “Scientists” do research in entomology and forest pathology. “Forest advisors” advise owners on the management of their forest. “Civil society” includes forest users or members of NGOs. The “Forest authorities” are in charge of the implementation of legal measures on forest management. “Forest health surveyors” refers to engineers and technicians in charge of monitoring and controlling forest pests and pathogens. The superposition of the bars corresponding to these six groups does not follow any particular hierarchy. It was chosen to maximise the clarity of the figure.
