You should seek professional advice on the management of trees from a qualified tree surgeon (arborist) or tree specialist (arboricultural consultant). See the managing your trees page for more information.
You should only report diseased ash trees to Cornwall Council when:
- The land they are growing on is owned by Cornwall Council
- They are posing a threat to the highway due to their poor condition.
- They are posing a threat to users of land or buildings within the control of Cornwall Council
In all other cases the trees are the responsibility of the landowner.

Cornwall Council has very limited powers to act in the case of privately-owned trees if there is dispute or a landowner cannot be identified. 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 how and when the Council might take action is provided in our Dangerous Trees Advice Note.
