Deliverable D1.1 of the Horizon Europe ForestNavigator project presents the report on stakeholder mapping and internal stakeholder database. The report describes the mapping process and outcomes as well as the dynamic internal stakeholder database. ForestNavigator identifies and maps stakeholders from the sub-national to the international scale based on a set of characteristics, such as stakeholder category, geographical scope, and sociodemographic factors. The aim of the mapping process is to provide a comprehensive and diverse stakeholder base for stakeholder engagement activities throughout the project. The report further describes the dynamic stakeholder database, which will be updated throughout the project lifetime.
