I'm focused on forest functions, their evaluation and position within ecosystem services systems. It is easy to find gerenal information about systems like TEEB, CICES, MEA or FEGS and their mutual connections. It is possilbe to find a lot of scientific research results focused on specific ecosystem aspects of forest ecosystem functions (soil processes, water runnof etc.). But I've tried to find more complex systems of forest function evaluation (like e.g. Vyskot et al.) nad use as ecosystem base for evaluation of forest ecosystem services (potential of forest ecosystem to fulfil social needs). Maybe there are research reports more useful than articles in journals?
