This article describes a composite indicator for ecosystem services. This composite is composed of several sub-indices, each representing either land use types or ecosystem services. While the overall composite indicates a general overview of the performance of a system in terms of ecosystem services provision, the sub-indices provide sources of variation. Taking into consideration potential trade-offs between making the framework complex and keeping it simple, the composite was developed on two levels. The first level , a simpler one, requires few indicators and therefore needs less data as inputs. The second level, in contrast , is more complex requiring more indicators, involving more detailed measurements, and therefore can be applied with more confidence.
