Some provisioning services come from one dominant ecosystem, whereas
most of the regulating and cultural services cover a wide variety of ecosystems.
The importance of
forests is clear: they feature in all 13 categories of ecosystem
services and they are the main focus in studies of freshwater provision,
carbon storage and flood prevention.
Wetlands feature strongly in studies of water flow and
water quality regulation. Coastal environments are important for
species-based recreation, including eco-tourism (e.g. whale and dolphin
watching) and recreational fishing.
