Reporting Ash Dieback

It is recommended that you check whether there have been any other incidences of ash dieback in your area. You can check this on the Forestry Commission Interactive Map.

If there are no confirmed incidences of ash dieback in your area you can report the sighting at Tree Alert (Forest Research)

You should seek professional advice regarding the management of trees from an appropriately qualified tree surgeon (arborist) or tree specialist (arboricultural consultant). See the Choosing a tree specialist or tree surgeon page for more information. 

You should only report diseased ash trees to Cornwall Council in the following circumstances:

  1. The land they are growing on is owned by Cornwall Council
  2. They are posing a threat to the highway due to their poor condition.
  3. They are posing a threat to users of land or buildings within the control of Cornwall Council

In all other circumstances the trees are the responsibility of the landowner

You can report diseased ash trees that pose a threat to the highway using our on-line reporting system.

To report diseased ash trees that pose a threat to users of land or buildings within the control of Cornwall Council please call 0300 1234 222.

Cornwall Council has very limited powers to act in the case of privately-owned trees where there is dispute or a landowner cannot be identified. Furthermore, these are used in exceptional circumstances only. If you are concerned about the safety of privately-owned ash trees you should raise your concerns with the landowner.

More information, including details of how and when the Council might take action is provided in our Dangerous Trees Advice Note
