How to effectively inform decision-making on biodiversity and ecosystem services has been under continuous debate in Europe and globally since the Convention on Biological Diversity was adopted in 1992. On the global level the Intergovernmental science-policy Platform on Biodiversity and Ecosystem Services was installed in 2012 to address this need. Yet, biodiversity and ecosystem services management have to be addressed on multiple levels, across biophysical as well as administrative scales. Also, the knowledge needed to address them has to be brought together from science, management practices and other knowledge domains to become relevant and it must be delivered in ways relevant for policies beyond the environmental sector. This Special Issue brings together papers that analyse the challenges arising from this context. Most of them are based on the EU-funded project KNEU that aimed at developing a new, integrative approach to activate knowledge holders and bring them together for targeted knowledge synthesis activities. The papers address the potential functions, structures and processes of such activities in a joint framework, the Network of Knowledge. Practical aspects are addressed via a number of trial assessments carried out in the project. All in all, they
