<dc:description>Context&#xd;
Information about variations in basic density (BD) and carbon content (%C) along tree stems is key to assessing forest carbon sinks.&#xd;
Aims&#xd;
The aim of the study was to determine any differences in %C and BD between different woody tissues (bark,&#xd;
sapwood and heartwood) in two widespread European oak species (Quercus pyrenaica and Quercus petraea).&#xd;
Methods&#xd;
Twenty trees were felled in northern Spain, and 317 discs cut from the trees were dried and analysed to determine %C and BD.&#xd;
Results&#xd;
There were significant differences in %C between bark, heartwood and sapwood, and between species. There&#xd;
were also significant differences in BD between the tissues (heartwood>sapwood>bark), and the BD was higher in&#xd;
Q. petraea than in Q. pyrenaica. Both %C and BD varied along the stem.&#xd;
Conclusion&#xd;
More accurate estimates of carbon contents were obtained by using specific values for different heights and anatomical parts, than by using single values.</dc:description>
