Decision making about the management of socio-ecological systems that produce Ecosystem Services (ES) are complicated by the terms, number of factors involved in the processes and their interactions, and perceptions of the actors. This paper aims to propose a methodology to integrate knowledge about the processes of ecosystem change and decision making, highlighting the role of SE. Through a workshop of experts, and based on existing information and calculations ad hocthree methodological proposals were integrated: (1) Models States and Transitions, modelling ecosystem behaviour, its ways of degradation and recovery; (2) the definition and quantification of the ES provided by each of the states of the ecosystem, considering the final ES end, benefits andmonetary value and (3) A Decision Making Models, based on Bayesian networks which considers the final objectives through a matrix of values; intermediate objectives and possible management decisions that impact on them. The proposal is exemplified by Nothofagus antarctica forests of northern Patagonia.
