Trees outside the forest are an arboreal heritage that grows outside the traditional boundaries of the forest, found in cities, towns and villages, in gardens, parks, along watercourses, in agricultural spaces and other formations. For a long time, these trees remained outside the certification universe, not because they were less important, but because there was a lack of a framework capable of recognizing the specificity of their management and the contribution they make to the territory.
It was to address this reality that the PEFC – Programme for Endorsement of Forest Certification certification emerged for "Trees Outside Forests" (TOF). This innovative approach extends the scope of sustainable management and internationally recognizes a heritage that has always existed, but which was not yet included in the certification system.
Portugal takes a prominent position by becoming the third PEFC member to obtain international recognition for this certification, establishing itself as one of the pioneering countries in this new approach. This certification represents a more integrated vision of sustainability, where every tree is valued for the contribution it brings to people, communities and the environment.
Trees outside the forest provide indispensable environmental, social and economic benefits, such as improving air quality, regulating temperature, water infiltration into the soil, carbon capture and promoting biodiversity. In urban settings, they create spaces for socialization, provide shade and promote health and well-being, while in rural areas they continue to be part of landscape identity and the collective memory of communities.
