11 Country involvement (FRA 2005) 172 national correspondents 229 country reports 800+ contributors

12 National forest inventory Forest management plans Data sources (FRA 2005) Sources of trend data for forest area and forest carbon stock in country reports to FRA 2005 Quality Maps Independent reports Case studies / Models Annex I - Forest area Annex I - Carbon stock non-annex I - Forest area non-annex I - Carbon stock Expert estimates No data n countries

13 Data collection options Method Field Measurements Feasible variables Pros Cons Biophysical Precise Only measurables Field Observations Biophysical Land use Wide range Judgements Remote Sensing Some area measures Costeffective (?) Limited scope Interviews Uses, Users, Values, Tenure, Conflicts Captures socioeconomics Demanding

14 National monitoring - the base of global reporting Lappland, Sweden 1927

15 FAO country support

16 Examples

17 Sampling Nationwide Low intensity field sampling ( ) Systematic (based on lat./long. grid) Permanent plots for long term monitoring e.g. Kenya ~ 500 tracts 15 x10 in Stratum 1 (highland / coastal) 30 x 30 in Stratum 2 (dryland) Stratification may be applied to improve sampling efficiency based on stable strata (ecological zones)

18 Basic design Plot end point 20 m 1 0 m Tract 500 m Systematic sampling grid 250 m 125 m SP3L1 and SP3L2 SP2L1 and SP2L2 Plot central line Plot Tract X,Y coordinates Plot 1 Plot m 1 Km Plot orientation (- 10m) 20m Towards end of the plot Plot 4 Plot 3 Measurement Point (MP) (+ 10m) 1 Km Plot starting point SP1L1 and SP1L2 Subplots Subplot Level 1 (SPL1) 3.99 m. Towards starting point of the plot 1 0 m Subplot Level 2 (SPL2)

19 Local interviews Data collection Measurements of biophysical parameters Direct observations

20 Country example Growing stock Trees are everywhere Forest volume on inventoried tracts 500 Tree volume m3/ha Agriculture / Urban land Other Wooded Land Forest 100 0

21 Country example Growing stock 500 Volume/ha Agriculture Woodland Forest Conclusion: Monitor all land!

25 Remote sensing survey

26

27 Remote sensing survey Distribution of forests Accurate trend statistics Regional, biome & global level Option to intensify for countries

28 Conclusions 1. Strong synergies in monitoring between Climate Change needs and Overall needs 2. Monitoring Accounting 3. But Accounting requires Monitoring 4. Unique opportunity for investing in Forestry/Land use knowledge
