Restoring degraded natural habitats such as peatland and coastal marsh is crucial if Britain is to meet its ambitious climate change targets, according to a report from the Wildlife Trusts charity. UK grasslands store 2 billion tonnes of carbon, but this is vulnerable to disturbance. Between 1990-2006, arable conversion of grasslands released 14 million tonnes of CO2. We can restore species-rich grasslands to lock up carbon and support abundant wildlife.
