It is important to be able to recognise when a tree is healthy or not. You may well be asked this question many times by concerned local residents. Whilst you may not be a professional arboriculturalist it is none the less useful to have a basic knowledge of tree health, so you can point someone in the right direction.

Below are three identification papers that may be of interest to you. They are not wholly conclusive and should not be used solely to identify any tree health issues. Remember if you are not professionally qualified always ensure a professional second opinion is sought.
In addition, there is a fourth document, Pests and Diseases of the Future, a presentation made by Derek Patch at the Tree Warden Co-ordinator’s Conference, 2007, about the affects on trees of climate change.
