Chalara dieback of ash trees

Do not bring infected leaves or branches to our sites. 

Management of ash leaves and saplings

The Forestry Commission have issued the following advice for green garden waste:

  • “Householders [should not] put out green waste suspected of being affected by Chalara, but to deal with it within the grounds of their own premises, in all but exceptional cases.” Several options are suggested, with burning on site preferred. “Burning [can be] on the ground or in mobile incinerators brought to site (where these are used because they offer a practical solution to deal with a high volume of leaves) where allowed … and subject to the potential risk of smoke nuisance. The best way to do this is for householders, farmers and landowners to be considerate by advising their nearest neighbours before lighting a bonfire, so that they can be prepared for any minor inconveniences which might arise.”
  • “Where there is no suspicion that trees or leaves are infected with Chalara and there is no need to remove the leaves, they can be left where they fall. Where leaves need to be removed, e.g. as part of normal maintenance existing waste management arrangements may continue to be used.”

Managing infected trees

Forestry Commission advice is that: “You are not required to take any particular action if you own infected ash trees, unless [the Forestry Commission] or another plant health authority serves you with a statutory Plant Health Notice. You should, however, keep an eye on the trees’ safety as the disease progresses, and prune or fell them if they or their branches threaten to cause injury or damage. You can also help to slow the spread of the disease by, where practicable, removing and disposing of infected ash plants, collecting up and burning, burying or composting the fallen leaves.”
