Indicators can be defined as a measure based on verifiable data that conveys information about more than itself. Biodiversity indicators are a central part of effective decision-making and adaptive measurement. This guidance document produced with the support of the Biodiversity Indicators Partnership (BIP), responds to a mandate in the 2010 CBD Decision on Outcome-Orientated Goals and Targets (Decision X/7) to support 'national and regional efforts to establish or strengthen biodiversity monitoring and reporting systems to enable Parties to set their own targets and assess progress towards biodiversity targets established at national and/or regional level'.
