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).
