The Montado is a silvopastoral system with a tree cover of predominantly Quercus suber but also Quercus rotundifolia, where cattle or sheep graze the understory. It occupies more than one million hectares in southern Portugal, and a similar landscape, the Dehesa, covers ca. three million hectares in Spain. These silvopastoral systems can simultaneously benefit the environment and socio-economic activities by providing a bundle of ecosystem services (ESs). However, an ongoing trend of decline in tree density and the covered area is threat ening such provision. Policies are needed to motivate farmers to secure the ESs that they provide. One possible format is the development of a results-based model (RBM) for agri-environment schemes (AES), implemented under the Common Agricultural Policy. In an RBM, farmers are paid when they deliver specific environmental results (ERs) (e.g. healthy and functional soils), that are linked with the provision of different (and often mul tiple) ESs. This study defines possible ERs for the Montado and details how these results are linked to the pro vision of ESs. It then considers management actions that can allow the achievement of these ERs and the costs of these actions. Our methodological approach is based on a transdisciplinary dialogue involving researchers, practitioners (i.e farmers), public authorities and policy makers. The results of the process include the identi fication of four main ERs: a healthy soil ecosystem, a biodiverse native-Mediterranean pasture, an oak tree layer where regeneration exists (i.e. trees of different ages), and preserved or enhanced landscape elements, for example riparian galleries with vegetation. These ERs increase the supply of provisioning services (e.g. cork production), of regulating services, (e.g. carbon sequestration), and cultural services (e.g. aesthetic inspiration). RBMs allow farmers to use any management practice they choose as the focus is on the results. Nonetheless, to estimate costs we identified 12 potential strategic management practices (and their cost) along with the technical support that farmers would need. We conclude that an RBM could be an affordable solution for public policies in the Montado system, given the limited government budget for supporting AES.
