Ash is one of our most beloved and common trees in the UK and at the Woods at Oakley, but it is under great threat from ash tree dieback. It is estimated that the disease will kill around 80% of ash trees across the UK in the next 10-20 years. This will have a devastating impact on the landscape, the biodiversity of our woodlands and will cost the UK £15 billion! The UK's woodland needs your help to protect it.
