El Triunfo Biosphere Reserve (REBITRI) is at risk due to ignorance and the inadequate assessment of the important ecosystem services (SE) that it provides; the lack of information on the subject limits the design of strategies for their permanence. The aim of this study was to diagnose the offer, threats and conservation strategies of the SE that the reserve brings, from a representative watershed. It was developed in four stages: gathering available information; SE characterization through five workshops and 61 interviews with the participation of the local population; production of images of interest and, validation and feedback of results by local villagers. Eight types of SE, among which are the food, fiber and fuel and soil formation and retention were identified. Forests (61 % of the territory) are a priority supply of SE. The increase of the agricultural frontier, population growth, intense and erratic rains and government incentives are the main threats to forests. Among the strategies to ensure the supply of forest SE include payments for environmental services, community agreements and intercommunity for the preservation of resources, limiting agricultural burning, conservation practices cultivated soils, increase of human and social capital and improving the efficiency of land use for agricultural use.
