Dating spotted gum (Corymbia citriodora) tree rings in south-eastern Queensland using 14C measurements of cellulose

Summary Application of a radioisotope dating technique to a spotted gum (Corymbia citriodora) tree in south-east Queensland showed that the observed growth rings were annual. The dating technique is based on a comparison between the concentration of C measured in tree ring cellulose and historical measurements of C in the atmosphere. This information improves our understanding of forest processes and growth over time, and undoubtedly will contribute to more efficient measures of forest growth.
