Forest fires and forest biodiversity are related issues of major concern in Mediterranean countries and require an integrated approach to landscape planning. The aim of this study was to develop a GIS approach for regulating forest production while promoting landscape diversity and mitigating fire hazard. A study area located in the centre of Portugal was chosen. The area was primarily occupied by maritime pine and had a high fire hazard, low tree species diversity and an extensive protection area. The classical area control method was used to assist in forest production regulation. Species suitability maps were produced for 21 recommended species for afforestation in the study area. Maritime pine management compartments were defined, and a 50-year harvesting plan was proposed. In each harvested compartment, protection areas were identified for species conversion (e.g., native oaks and/or broadleaves). Afforestation species were proposed according to the species suitability maps produced earlier. Low flammability species that produce high-quality wood, non-wood products and landscape enhancement were preferred. A comparison of the land cover in the study area in 2007 to that anticipated in 2064 via the proposed plan showed that a more fragmented landscape structure could be achieved by introducing 16 species of lower flammability than maritime pine into the study area. This study proved the usefulness of this methodological approach for guiding sustainable changes in homogeneous, unmanaged forest landscapes prone to fire. Further research is needed regarding integrated planning approaches that incorporate environmental, economic and social dimensions (e.g., human desertification of rural areas).
