Introduction
As part of the Integration component in the Carbo Europe IP, we concentrate
on improving the spatial detail of the inventory based carbon budget of
European forests. Earlier analyses often showed an NBP in the range of 70 –
100 Tg C y-1. However the spatial detail was limited to the national level or in
some cases to the provincial level (fig 1).
Methods & preliminary results
A possible source for improvement may be in the sample
wise forest inventories plots. In total some 420,000
inventory plots are measured annually. Through detailed
questionnaires to all 38 national inventory institutes in
Europe, we plan to acquire the detailed plot level data. For
seven countries the data have been received by now (fig 2 &
3).
