UK forests lock away twice as much planet-warming carbon as previously thought, a new study reveals. The study using lasers and 3D scanning showed that old trees in particular were critical to fighting climate change. …An accurate calculation of the amount of carbon trapped in UK woodland could help inform decisions about how to manage it – in addition to highlighting the cost to the environment of losing that woodland. …It showed that a patch of UK forest weighs about twice as much as previous calculations suggested. …And the complex structure of mature trees in particular means they play a role that is very difficult to replace by simply planting more trees. “The value you have in large mature trees is almost incalculable, and so you should avoid losing that at any cost – regardless of how many trees you think about planting,” said Prof Mat Disney, from UCL.
