CICES classification version 4.3

CICES for ecosystem service mapping and assessment Note: this section is not complete and for illustrative purposes only. Key components could change by region or ecosystem.
CICES for ecosystem accounting Note this section is open in that many class types can potentially be recognised and nested in the higher level classes, depending on the ecosystems being considered.
Section Division Group Class Class type Examples
This column lists the three main categories of ecosystem services This column divides section categories into main types of output or process. The group level splits division categories by biological, physical or cultural type or process. The group level splits division categories by biological, physical or cultural type or process. Class types break the class categories into further individual entities and suggest ways of measuring the associated ecosystem service output.
