Provisioning services – all products coming from ecosystems, for example food, fiber, fuel, herbs and medicinal plants, genetic resources, drinking water
Regulating services – the capacity of ecosystems to regulate important natural processes, for example regulation of climate, quality and quantity of water, etc.
Cultural services – non-material benefits from ecosystems, for example the aesthetic and recreational value of landscapes
