UNEP-WCMC In collaboration with the International Union for Conservation of Nature's Commission for Ecosystem Management and the World Resources Institute organized and hosted an international workshop on Ecosystem Service Indicators 22-23 September 2009. Funded by the Swedish International Biodiversity Programme, the workshop brought together 16 experts from all over the world in the fields of indicators and ecosystem services. The aim of the workshop was to identify a suite of ecosystem service indicators of policy relevance, and the datasets available and, or, necessary to underpin them, that could be applied within assessments and monitoring at different scales.
