Species-rich forests take up twice as much carbon as monocultures - Earth science news

Subtropical forests with a rich variety of tree species store more than twice as much carbon as monocultures, new research shows. This has been concluded after evaluation of data from forests that had been planted especially for this study in China, and included over 150,000 trees. Species-rich forests stored 32 tons, while monocultures stored only 12 tons of carbon per hectare. These data follow the ones that had already been documented for grasslands in the US and Europe, and indicate that reforestation should involve the planting of many different tree species for better productivity and protection from climate changes.
