C stock (2000) EU13+2 (N, CH)
C stock (2000) • On average: • 55 % in the soil • 35% in the aboveground biomass • 10 % in the belowground biomass Age distribution, species, etc.
-1.00 – 0.00 0.01 – 2.00 2.01 – 3.00 3.01 – 4.00 4.01 – 4.50 C stock change (1995-2010)
Assumptions: • Forest area: • Available for wood supply • Constant (no ARD) • FM: according to country indications • Wood demand ( fellings) based on: • Roundwood production statistics of FAO • from 2006 slow increase in demand (OECD projections)
C stock change (1995-2010) • 8.3 % increase of C stock • 11.7% in biomass • 5.6% in the soil
Large range of variability (regions): +31% to -6% of C stock change (1995-2010)
LIMITS • Biomass: • Inventory data: updates • Biomass factors, turnover rates, ... • Forest area = available for wood supply, no changes • Low resolution (Med. Countries) • Soil: • Input data (litter quantity/quality, climate): NO soil type • Validated for Nordic countries • ...
Next steps • Develop estimates for EU25 • Evaluation of parameters to be applied in new countries • Increase resolution (?) • COMPARISON with other estimates
Thank you for the attention!
