The Independent reports researchers for Natural England carried out a comprehensive survey of the role different types of natural habits in Britain play in capturing carbon from the atmosphere, looking at forests, grasslands, heathlands, salt marshes and seagrass meadows and how much they store in their soils, sediment and vegetation.
They found that undisturbed woodlands and peat bogs had the highest rates of carbon sequestration, with a hectare of ancient woodland capable of storing the equivalent amount of carbon dioxide each year that would be emitted from 13 plane journeys between London and Rome. A 10-metre deep fenland peat bog can store eight times as much carbon as the equivalent area of tropical rainforest.
