The net-accumulation of C, with a standard sink factor of 0.5 t C ha y -1 for the former agricultural
area is included In the CRF-Table 5.D. The total annual net - build up from anthropogenic wetlands
in 2003 - is estimated to 3.17 Gg C (only former cropland and grassland is included) (Table
7.21). The decreased oxidation of organic matter of the organic soils (due to the re-wetting) is included
in Table 5.B and 5.C as a decreased total area. Until a full matrix for the Danish area is performed
there will be some inconsistency in the total area.

C-stocks in settlements are not estimated. The annual changes in C-stock in settlements are assumed
to be negligible, but because no estimates have been made it is reported as NE in the CRF
table 5.E
7.7 Other
C-stocks in other types of land are not estimated. The annual changes in C-stock in other types of
land are assumed to be negligible, but because no estimates have been made it is reported as NE in
the CRF Table 5.F
