  3. Purpose: Overview of state and trends of biodiversity • Measure state and trends of biodiversity in natural ecosystems, including the cultural landscape. • Reflect threats to biodiversity: The combined effect of all pressure. • Combines current biodiversity knowledge in a common conceptual framework (expert-judgements and monitoring data). • Measurement tool for government policy and management www.dirnat.no
