Ash Dieback The Facts

Posted on July 10, 2019

Ash Dieback South West are saddened by the devastation caused by Ash Dieback or Chalara and committed to helping inform and advise in any way we can.

The latest information from that Ash Dieback has now taken hold across much of the UK, including Devon. The disease will have a major impact on Devon’s Ash Trees and countryside, which is populated with hedges, hedgerow trees, small copses and woodland. Evidence states we will lose over 90% of Ash Trees, which will no double result in the character of our landscape changing dramatically, with loss of trees, hedgerows and the wildlife that resides in them.

Where you come in?

My Tree My Responsibility.   My Tree My Responsibility is a campaign launched by Devon County Council launched in July 2019 and is their latest campaign to raise public awareness about ash dieback it promotes the following:-

  • Don’t wait until Ash dieback makes an older tree unstable. 
  • If you are a landowner, you are responsible for managing the health and safety risks from dead and dying trees on your land. Monitor trees near highways and rights of way or areas with high levels of public access for signs of the disease, and if risk assessments show these as a hazard, plan careful pruning or felling by an Arboricultural Association Approved Contractor such as Teign Trees & Landscapes SW Ltd.Teign Trees & Landscapes SW Ltd

There are may signs to look out for on ash trees. All of these can also be caused by other problems, so accurate diagnosis should be made by an expert.


  • Dark long, thin, diamond shaped marks – at the base of dead side shoots
  • The edge of leaves become black and shrivelled
  • Blackened, dead leaves – may look similar to wind or frost burn
  • Veins and stalks of leaves turn brown
  • Saplings display dead tops and side branches
  • Older trees, show dieback of crown branches, often with bushy growth further down where new shoots have sprouted


  • The disease is spread by spores from the fruiting bodies of the fungus produced on fallen ash leaves. These spores spread via wind over a large distance
  • Before the October 2012 ban on the movement of ash trees, spread over longer distances was likely to have been via the movement of infected stock.
