Ecosystem restoration initiatives present natures as intervention-requiring problems. However, not all stakeholders may be able to recognise and relate to the issues that motivate restoration. Instead, they may put forward alternative understandings of natures as problematic issues in need of management and collective action. Therefore, ecosystem restoration can turn generative into new forms of publics that are brought together – and drawn apart – by distinctive configurations of nature-issues. This paper analyses such a reorganisation by focusing on three restoration projects carried out in Finland. The projects sought to engage farmers in restoring agricultural streams while proposing the practice of stream restoration as an extensive ecosystem revitalisation. In the studied cases, farmers could become attentive to the potential of stream habitats to develop into viable and rich ecosystems, while their neighbours only showed interest in improving the drainage functions of streams. The restoration initiatives generated connectedness between farmers, streams habitats and the restoration projects, but also disconnectedness between natures and publics. The possibilities of the studied projects to carry out their restoration plans rested mostly on the specification of the restoration plans as a means to manage ontological differences. The findings indicate that instead of promoting ecosystem restoration as a tightly coupled practice, it can be useful to generate space for collective action that unfolds in terms of partially different natures and nature-issues.
