This report presents the findings of preliminary research on the Woodlands for Health project which involves a nature-based intervention for mental health and well-being in Coillte forests. The f indings indicated an improvement in well-being (on average 31%) and nature connectedness (on average 11%). These findings merit further systematic research and provide tentative support for the programme. Additional co-benefits for sustainability, enhanced environmental concern and potential increases in pro-environmental behaviour should be considered in future studies. Overall, the findings suggest positive impacts upon participants with potential significant reciprocal benefits for those engaged in coordinating the programme on-site.
