Alastair Collier is right to point out that to build forests that can withstand future conditions, we must invest in resilience from the outset (Britain’s forests need help to adapt to the changing climate Letters, 17 July). At Forestry England, forest resilience is our most critical challenge. We must ensure the nation’s 1,500 forests in our care can withstand and adapt to the threats facing them, including climate change, biodiversity loss, extreme weather, and pests and diseases. We are doing this by planning 100 years ahead in the way we manage these beautiful places, which are home to some of the UK’s rarest wildlife. …The benefits of the nation’s forests are enormous, from storing carbon and mitigating floods to supporting our health and wellbeing. They are an unsurpassed national asset. As their custodians, we are putting forest resilience at the heart of everything we do.
