World forests capturing more carbon

In Europe and North America, increased density significantly raised carbon storage in trees despite little or no expansion of forest area, according to the study, led by Aapo Rautiainen of the University of Helsinki, Finland.
Even in the South American nations studied, more density helped maintain regional carbon levels in the face of deforestation, reports the journal Public Library of Science.
The researchers analyzed information from 68 nations, accounting for 72 percent of the world's forested land and 68 percent of reported carbon mass, according to a Helsinki statement.
They conclude that managing forests for timber growth and density offers a way to increase stored carbon, even with little or no expansion of forest area.
