2 Set-up Presentation  Sources of comments  General comments on Transparency  General comments on Conservativeness  Comments on Transparency & Conservativeness in calculations

3 Sources of Comments  Lucio Pedroni, Cati  Bernhard Shclamadinger  Robert Seaton, Brinkman & Associates reforestation Ltd.  Federal University of Paraná & Instituto Ecoplan (Brasil)

4 General comments on Transparency There is no scenario of possible land-cover sketched; SO NO SOUND ARGUMENTATION FOR THE BASELINE SCENARIO CHOSEN Policy, social, economic and environmental issues are considered fixed; IT IS NOT EXPLAINED WHY THIS IS LIKELY Project boundary NOT CLEARLY DEFINED

5 General comments on Conservativeness DIFFICULT TO ASSESS, because re-calculation of the derived figures is difficult THROUGH LACK OF TRANSPARANCY

6 Calculation total vegetative biomass Biomass live trees Biomass dead standing trees Biomass of dead fallen trees Shrub and herb biomass Biomass of roots Biomass of forest fuels (litter) + TOTAL VEGETATIVE BIOMASS

7 Calculation total vegetative biomass Biomass live trees Biomass dead standing trees Biomass of dead fallen trees Shrub and herb biomass Biomass of roots Biomass of forest fuels (litter) + TOTAL VEGETATIVE BIOMASS

8 Biomass live trees = 0, 1184 DAP 2,53 (later replaced by allometric destructive sampling) COMMENTS ON TRANSPARANCY: Source of equation is missing Point of time of replacing this equation with allometric destructive sampling is missing

9 Calculation total vegetative biomass Biomass live trees Biomass dead standing trees Biomass of dead fallen trees Shrub and herb biomass Biomass of roots Biomass of forest fuels (litter) + TOTAL VEGETATIVE BIOMASS

10 Biomass dead standing trees = Biomass living trees = 0,1184 DAP 2,53 COMMENTS ON CONSERVATIVENESS: Biomass dead standing trees should be corrected for density loss, for instance using “Machete test”

11 Calculation total vegetative biomass Biomass live trees Biomass dead standing trees Biomass of dead fallen trees Shrub and herb biomass Biomass of roots Biomass of forest fuels (litter) + TOTAL VEGETATIVE BIOMASS

12 Biomass dead fallen trees = 0,4 DAP 2 L0,25 COMMENTS ON CONSERVATIVENESS: 0,4 Should be adjusted for density class doing “Machete test”

13 Calculation total vegetative biomass Biomass live trees Biomass dead standing trees Biomass of dead fallen trees Shrub and herb biomass Biomass of roots Biomass of forest fuels (litter) + TOTAL VEGETATIVE BIOMASS

14 Biomass of roots = exp[-1, ,926 ln(total biomass of trees and shrubs)] * * Caims et al, 1997 COMMENTS ON CONSERVATIVENESS: Only biomass of roots of living trees should be calculated COMMENTS ON TRANSPARENCY: The source of this equation is not stated correctly, it should be: Cairns et al, 1997

15 Calculation of carbon total vegetative biomass = total vegetative biomass * 0.45 COMMENTS ON CONSERVATIVENESS: Conservative; IPCC-guidelines default value is 0.5
