Woodland expansion is a ‘nature-based solution’ which is now recognised as potentially one of the most effective climate change mitigation options to date, with the capacity to absorb and store large volumes of carbon, reduce river flooding and support biodiversity. However, it remains unclear whether natural tree establishment can supply demand for expanded oak woodland in the UK uplands, where they are needed to reduce downstream flood risk.
“Reaching UK carbon net zero by 2050 requires the creation of 30,000 hectares of new woodland a year.”
