1. Final Meeting Development of Harmonised Indicators and Estimation Procedures for Forests with Protective Functions against Natural Hazards in the Alpine Space Introduction and Overview

2. Final Meeting Long time ago … A group of young and fearless scientists tried to cross the Alpine Space. After a one week‘s walk without any stop, freezing and suffering from thirst and hunger … they decided to define common indicators to describe their hopeless situation in a harmonized way. In case they have not died - they are still alive … and live in harmony

3. The main idea: Merging expertise from Forest Remote Sensing Experts National Forest Inventory Experts Natural Hazard Experts/Modellers

4. Final Meeting The consortium: NFI NH RS BFW WSL BOKU IFN Cema gref Gozdis LWF

5. Final Meeting Main Objective: to explore the possible contribution of the National Forest Inventories (NFIs) and other forest monitoring systems to assess the protective functions of forests in the alpine space

6. Final Meeting Operational Objectives: –to identify and derive the protective effect –to detect protection forests –to select indicators or proxies –to define thresholds –to verify the possibilities of combining field data with RS techniques

7. Final Meeting P D H General approach: Three system components Hazard Potential Damage Potential Protective effect

8. Final Meeting General approach: H P D

9. Final Meeting Which Hazard processes?

10. Final Meeting Hazard process: Avalanche

11. Final Meeting Hazard process: Avalanche

12. Final Meeting Hazard process: Rockfall

13. Final Meeting Hazard process: Rockfall

14. Final Meeting Hazard process: Landslide

15. Final Meeting Which scales: -Coarse scale approach -Coarse scale mapping -Coarse scale statistical -Fine scale approach

16. Final Meeting Coarse scale mapping: -Mapping of protective effect -Indirect use of NFI plot data -Landsat imagery -also cross-boarder

17. Final Meeting Coarse scale statistical: -Frequencies of protective effect -Direct use of NFI plot data -Large areas -Landsat imagery -only for avalanche hazard

18. Final Meeting Fine scale: -Single valleys -Indirect use of NFI information -high resolution RS techniques -laser scanning -digital aerial photographs

19. Final Meeting Harmonized Indicators and Thresholds -Depend on -Hazard type (A, R, L) -System component (H, D, P) -Scale (coarse and fine) -Availability (NFI - Remote Sensing – other sources)

20. Final Meeting Working Steps: Forest mask Hazard potential Forest with potential protective function Forest with protective function Damage potential Protective effect

21. Final Meeting Outside the scope: Results and maps concerning the three system parts hazard potential, damage potential and protective effect, which are developed within ProAlp cannot be interpreted as concrete natural hazard indication mapping or risk zone planning

22. Final Meeting Inside the scope: The intention of ProAlp is a science based development of indicators and procedures to evaluate the protective effect of forests. Delivered maps and figures are examples for the capability of the developed methods. of the developed methods. Delivered maps and figures are examples for the capability
