Carbon cycling and species composition: seeing the forest for its trees

e eucalyptus trees were planted alone. The researchers believe that this is due to the nitrogen-fixing qualities of the Albizia trees.

Kaye and his colleagues studied carbon storage in forest stands planted 17 years ago with differing species composition. Some stands were planted as pure eucalyptus, some as pure Albizia, and some with the two trees planted together. The researchers found that in stands where the two species were interplanted, the forest contained twice as much carbon in trees as one-crop areas. In addition, areas of pure Albizia sequestered about 20 percent more carbon in soil than did the pure Eucalyptus stands.

"Carbon sequestration is the balance of inputs and outputs from a system," explains Kaye. "What we've shown here is that carbon outputs from soil are lower in stands that have more nitrogen-fixing trees. If decomposition is inhibited because of nitrogen inputs, then increased biological nitrogen fixation, nitrogen fertilization and nitrogen deposition may promote carbon sequestration." The mechanisms at work in those processes, however, are still very poorly understood.

"Changes in the composition of tree species which result from land use or climate changes may have important feedbacks to terrestrial carbon sequestration," Kaye says. "We still need to learn more about how species composition may be affecting the soil of these and other forests in order to fully understand their ability to act as carbon sinks."
