Chalara dieback of Ash

Information on how to identify and report ash dieback.

Ash dieback (hymenoscyphus fraxineus) has been confirmed in West Sussex. Ash is the main broadleaved species of tree in West Sussex, covering 4,968 hectares or 20.8% of all broadleaved species.

The Forestry Commission website has information on:

  • what the Government and other groups are doing
  • how to reduce the risk of spread
  • confirmed sites, via a map.

To help you spot symptoms of the disease and report suspected sightings, visit the Forestry Commission website. 

Advice for woodland managers and countryside workers

The Forestry Commission has guidance on biosecurity measures to help prevent spreading diseases. Chalara advisory signs should also be displayed. There are two types: orange signs which should be displayed at entrances to publicly accessible wooded sites within 10 kilometres of a confirmed infection and blue signs displayed in other areas.

Advice for countryside visitors and householders

The risk of spreading the disease by visiting a forested area is very low, but you can help by following the advice to forest visitors from the Forestry Commission. 

Householders with ash trees on, or overhanging, their property should dispose of leaves or prunings in their normal general rubbish bin for collection.

Grants and guidance

The Forestry Commission has updated its Chalara management advice leaflets to take into account the most recent developments in its distribution and progression.
