14 Challenges for local/national assessments Identify relevant systems for HNV and assess their extent and status Identify key indicators that illustrate states and trends in the natural value of a specific area Improve data access Establish a dynamic classification system that is sensitive to transition between HNV types and states

15 Challenges for regional implementation Lomba, A., Guerra, C., Alonso, J., Honrado, J.P., Jongman, R., McCracken, D., Mapping and monitoring High Nature Value farmlands: Challenges in European landscapes. J. Environ. Manage. 143C,
