A forest's ability to store carbon depends significantly on the bedrock beneath, according to Penn State researchers who studied forest productivity, composition and associated physical characteristics of rocks in the Appalachian ridge and Valley Region of Pennsylvania. The results have implications for forest management, researchers suggest, because forests growing on shale bedrock store 25% more live, above-ground carbon and grow faster, taking up about 55% more carbon each year than forests growing on sandstone bedrock.
