This dataset contains social network and stakeholder data collected from Forest Landscape Restoration (FLR) initiatives in Rwanda and Ethiopia using the Net-Map participatory network mapping approach. The data capture collaboration relationships among FLR stakeholders, together with stakeholder attributes and influence assessments. Data were collected through participatory workshops in Rutsiro and Ngororero Districts (Rwanda) and the Lake Chamo catchment (Ethiopia). The dataset supports analyses of collaborative governance, social capital, trust and distrust dynamics, and collective action in forest landscape restoration networks.
