"[U]sing a novel methodology based on measuring the radiocarbon content of the carbon dioxide being released, the researchers found that the birch trees appeared to be stimulating the decomposition of soil organic matter. Thus, the research was able to identify a mechanism by which the birch trees can contribute directly to reducing carbon storage in soils."(Found through "Expansion of Forests in the European Arctic Could Result in the Release of Carbon Dioxide" - Science Daily, June 17, 2012)
