If trees are to be cared for properly there has to be a ‘programme’ of inspections in place which will cover all the site types that have to be managed. This includes streets, Parks, Housing estates and schools. An example of this is that trees in streets could be inspected once every 2 years, where as trees in parks or housing sites can be looked at on a 3-year rotation. These inspections are carried out by inspectors who are experienced in this work and are able to assess a tree and identify whether works are of an urgent or non-urgent type. General tree health is considered as well as the condition and colour of the leaves, branches, upper crown and the trunk. Once all this information has been gathered a schedule of work can be produced.
