Final Presentation Chatham House – 21 January 2010 23 June 2000 Eyre 3 consulting What’s the problem the way things are? • In July 2007 the Norwegian Government stated “Today there is no international or national certification that can guarantee in a reliable manner that imported wood is legally and sustainably logged”. • Certification requires sound, defensible and accurate geospatial data on certified forests • Can the latest spaceborne remote sensing technologies improve the forest monitoring system?

  10. 10. Final Presentation Chatham House – 21 January 2010 23 June 2000 Eyre 19 consulting The Third Dimension - Measurement of Timber Volume • The proposition was that: – Tree Height (TH) and Diameter Breast Height (DBH) could be correlated with the Palsar signal backscatter. If so, we could calibrate the geolocated field measurements of these biophysical parameters with the relevant EO measurement – Having calibrated the EO image, it should be possible to then estimate the basal area and timber volume for the whole compartment without employing the extrapolation process • We could then estimate biophysical parameters across the whole operation using EO data only Chatham House – Illegal Logging Meeting 20th– 21st January 2010 20th– Eyre 20 consulting Options for EO Calibration of biophysical functions System calibration could use either: 1 Individual geo-located point source field data sets could be used for inference of biophysical functions 2 Calibrated field data extrapolated to average compartment level estimates of timber volume BUT current standard operating practice is 2, and had to guide methodology 25 compartments Jessievale x 30 field data sites Calibration 51 Data Set COMPARTMENTS Biophysical Average of biophysical functions Mauchsberg 26 Compartments measures per compartment x 30 field data sites Chatham House – Illegal Logging Meeting 20th– 21st January 2010 20th– Contact: Eyre Consulting Ltd +44 1264 356 900 charles.eyre@sarmap.ch Page 10

  13. 13. Final Presentation Chatham House – 21 January 2010 23 June 2000 Eyre 25 consulting Value of EO based Biophysical Enumeration Service Service Applications and Benefits Forest Management Information inputs • Reinforce or replace field enumerating data • Global estimation at a single point in time • Automated data entry • Infilling data gaps on unmeasured compartments • Independent check field of enumeration programme • Supplant difficult to measure biometrics such as tree height Operational management • Reduce costs of enumeration Timber • Improve the enumeration programme by better targeting resource volume • Monitor/compare compartment growth estimation • Improve timber quality by optimising timing of pruning • Improved estimate of biomass removal and sales revenues • Improve mill operational efficiency • First time inventory or assessment of acquisition targets Forest Certification • Data transparency • Data independence • CB resource management – target certification work • Increase certifier’s independence of client’s data Chatham House – Illegal Logging Meeting 20th– 21st January 2010 20th– Eyre 26 consulting In Conclusion • Mapping service applies to any forest environment • Biophysical estimation: – ONLY tested and works on pine plantations – We know species with higher biomass present a problem with signal saturation. Maximum now expected to be 500 m3/ha – Service not yet tested outside plantations • Cost depend on area mapped. But – overall savings are likely if service is integrated with changes in enumeration programme and management systems Chatham House – Illegal Logging Meeting 20th– 21st January 2010 20th– Contact: Eyre Consulting Ltd +44 1264 356 900 charles.eyre@sarmap.ch Page 13
