Rehabilitation of empty, damaged or degraded lands, located throughout the national territory, in partnership with forest associations and municipal councils and with the financing and involvement of companies and citizens. The areas to be intervened are public or publicly managed and the actions are of an exclusively conservationist character, without any commercial objective.

The approach used is totally innovative in Portugal in the allocation of land to the participants, based on area of land and not on number of trees, and thus leaving the actions to be developed dependent solely on scientific and technical criteria. In order to strengthen the relationship between the participants and the intervened lands, they are all geo-referenced, and the geographic coordinates are included in the certificate of participation.
