Among the main effects of human activities on the environment are land use and the resulting land cover changes. Such changes impact the capacity of ecosystems to provide goods and services to human beings. The benefits obtained by people from ecosystems are called ecosystem services. This paper aims at developing a model of ecosystem services provisioning through trees in the Moribane Forest Reserve (MFR), Manica - Mozambique. The study was carried out using a social survey through semi-structured interviews to 149 out of 479 households living within the reserve, and its objective was to understand the level of supply and demand for wood products. A field survey through 72 rectangular 50mx20m plots was also conducted with 24 plots established in each of the three land types, namely Forest land Fallow land and Cropland. This was to understand the phytosociological aspects of the most used wood species for household livelihood. The results show that, of the 89 identified trees, 61 are used locally for different purposes, including house building, manufacture of utensils and fuelwood. The Fallow land is the main source of extraction of such resources. The Forests revealed higher levels of richness in terms of species (83.1%). Thirty-five point nine (35.9%) of these species are assumed to be the most used by the community. Analysis through the Bayesian Belief Networks model shows a trend towards unsustainability, where over 80% of landscape units (plots) in Fallow and Cropland are of Moderate and Low Importance, evidencing the risk of unavailability of ecosystem services in the near future if the use and management practices are not changed. Conclusion, the model shows that the stage of services provided by wood forest species in MFR is under threat due to swidden-fallow rotations agriculture practice combined with overpressure. The study can help the academic community in future studies by replicating the methodology used for monitoring purposes or conducting studies in other similar areas, and the results may support decision-makers in designing better strategies towards sustainability.
