These accounts measure the capacity or potential of ecosystems to deliver ecosystem services in a sustainable way. Typical indicators are Landscape Ecosystem Potential (LEP), Green Accessible Landscape Infrastructure (GALI) and Rivers Ecosystem Potential (REP). They reflect the fact that sustainable provision of carbon/biomass and water has to be compatible with the good functioning of ecological infrastructure, landscapes and rivers and that access to the many ecosystem regulating and socio-cultural services is better measured in the first instance by the abundance and health of the ecosystems which deliver them to people. Ecosystem health is assessed following the principles developed by David J. Rapport in his description of the 'ecosystem distress syndrome' (Rapport 2007). In contrast to provisioning.
