The most damaging tree disease since Dutch Elm

Ash is the third most common broadleaved tree in Britain. There are an estimated 60 million ash trees outside woodlands in the UK. Ash dieback disease was first officially recorded in the UK in 2012 and has spread rapidly, with only a small fraction of trees proving resistant. Since the arrival of ash dieback, The Tree Council has led research into the early responses and coping strategies of public landowners to this new disease.
