Dear Colleagues, IUFRO Units 4.04.04—Sustainable Forest Management Scheduling, IUFRO Unit 4.03—Informatics, Modelling, and Statistics and IUFRO Unit 4.03.03. Information management and information technologies are sponsoring a Special Issue of /Forests /(http://www.mdpi.com/journal/forests) on Decision Support to Address Multiple Ecosystem Services in Forest Management Planning We welcome the submission of manuscripts for publication in this Forests special issue (SI). This SI aims at contributing to our understanding of how we can enhance forest management planning, in integrating a wide range of ecosystem services (ES) and assuring a sustainable supply (e.g. products and services listed in the Millenium Ecosystem Assessment). We welcome manuscripts that focus on 1) models to help forest managers check the impact of management options on the provision of ES, 2) methods to help forest managers develop plans targeting the supply of ES, 3) methods to help forest managers analyze tradeoffs between a multitude of ES, 4) methods to help forest managers assess the sensitivity of the supply of ecosystem services to uncertain parameters, 5) multiple criteria decision support systems and 6) approaches to map the demand for ES and the quality and quantity of ES supply.  Papers submitted for publication in this Special Issue will undergo a rigorous peer review process with the aim of prompt and wide dissemination of research results and applications.
