The Ecosystem Service Provision Index as a generic indicator of ecosystem service supply for monitoring conservation targets

At present, most governments, particularly in low and middle-income countries, are not effectively using ecosystem services (ES) indicators for conservation monitoring, which is in part due to the complexity of current indicators.
