Table 1. Expected values and related uncertainties of selected forest ecosystem services in the region of Davos, Switzerland under different scenarios, calculated with a Bayesian network in which variables were not updated (no experts) or updated (experts) by an expert survey. Standard deviations (stdev) are given as percentages of the expected ecosystem services values.
