Brazil assumed in The Paris Agreement the commitment of 12 million hectares of forests restored by 2030, of which 5 million will occur in the Atlantic Rainforest. However, most of the remaining forest areas are located in private lands and there are a number of factors that difficult the adoption of restoration by landowners. The objective of this research was to identify and evaluate the collaborative strategies that used by the main participants of the forest restoration chains in the Atlantic Rainforest in the State of Rio de Janeiro, with the purpose to overcome barriers, take advantage of successful opportunities of these projects and achieve the region s economic, environmental and social sustainability. A descriptive research was carried out with a qualitative approach, based on in-depth interviews with specialists and chains participants and data collected in documents and restoration projects websites. The main barriers encountered include: logistical difficulties in the network; lack of qualified labor; low demand for restoration projects; lack of implementation of legislation; difficulties in integrating private and public efforts; poor communication between local actors; discussion setbacks related to the importance of biodiversity conservation. The most important collaborative strategies were identified (cooperatives, formal and informal networks, participation in Councils) and their effectiveness assessed. Recommendations were made to improve current strategies and adopt new collaborative strategies in order to contribute, with other economic and regulatory initiatives, to overcoming barriers.
