Sun Life is one of the Italian projects funded in 2013 by the LIFE + Nature & Biodiversity program of the European Community for the implementation of policies on nature and biodiversity and the development of the Natura 2000 network. The publication retraces the 4-year project through thematic studies that describe the project’s process divided in two stages. The first seeks the development of the framework of analysis regarding the conservation status of species and habitats; identified synergies and interferences of the various levels of governance with Natura 2000; and the state of the ecosystem services and green jobs. The second part describes the project outputs, including the new Financial Plan (PF) and the updating of the Priority Action Framework (PAF); the guidelines for farmers and foresters; the interventions for the development of green jobs and post Life projects; and a focus on the main project action corresponding to the definition of the Strategy for the management of the Natura 2000 Network in Umbria, as a governance tool for the protection and conservation of natural systems and Umbrian landscapes. The final parts describe the monitoring, dissemination and communication phases of Sun Life.
