Expanding participatory and network-centred engagement in urban nature, aiming at collective action and long-term benefits is a complex balance act. This article discusses a case in Copenhagen, Denmark, where the aim has been: (a) build active collaboration of actors engaging in improving urban nature (NaTur i Byen); (b) strengthen dialogue among land owners, public bodies, research, and entrepreneurship to pave the road for collaborative actions; and (c) develop new models for ecological and economic benefits in the long run. An analysis of the first phase of the project is carried out, using a multi-dimensional model. It shows that relations were developing, but a stronger set of aesthetic and knowledge sharing tools giving primacy to place could strengthen impact towards practical actions. The article discusses how such primacy of place and aesthetics could lead to an impact on urban nature, more focus on biodiversity, green spaces, and other climate change-related benefits for urban sustainability. A process model is suggested for improved public value and creation and governance of urban nature-based solutions.
