Combining scientific and local knowledge improves evaluating future scenarios of forest ecosystem services

•Scenario analysis generates insight to the short- and long-term provision of ecosystem services by forests.•We modelled four forest management scenarios based on local stakeholders’ preferences.•The modelling highlighted different time lags for the delivery of ecosystem services.•Stakeholders added a qualitative evaluation including considerations of risk and social acceptance.•Combining scientific and local knowledge can produce a multifaceted evaluation of future scenarios.
