There are many occasions when a tree report might be necessary. As professional tree surgeons, we get called out by homeowners who are concerned about the risks posed by a particular tree in their garden and also planners who want to make the best use of an area of land when designing new building projects. We also help public sector and commercial business owners assess the potential dangers of trees to the public and members of staff.
A tree survey records important information about a tree so owners or site managers can decide what action needs to be taken in the future to protect people and property. The report will record the species of the tree, its vital statistics including height and diameter, its age and most importantly its overall health – whether it shows any evidence of disease, injury of pest infestation and any areas of damage. The report will also estimate life expectancy and make recommendations on what steps should be taken to ensure it remains healthy in the future.
Some mortgage companies require a tree report to be carried out before agreeing to a loan because in rare cases, tree roots can cause damage to the foundations of a property which may result in structural movement and subsidence. Insurance companies might also ask for a tree survey to determine cover and liability.
Trees are the responsibility of a landowner and you have a duty of care to make sure your trees are safe under the Occupiers Liability Act 1984. An insurance company will not accept liability and pay out damages to anyone injured as a result of a fallen tree if the homeowner didn’t seek professional advice on the risks it posed and take reasonable steps to solve any problems. This means the homeowner could be held personally accountable for such an incident and face private litigation.
A tree report is a useful way of maintaining a regular record of a tree’s health and could include photographs for evidential purposes. It could also incorporate a tree safety policy to limit liability for homeowners and private businesses. By following the recommended advice, tree owners are complying with their responsibility to safeguard the public and property from dangerous trees.
Tree surgery has advanced considerably in recent years and a wide range of technology is now available to help conduct non-invasive tests measuring decay. Such processes will reduce the inconvenience to homeowners and businesses and help to protect healthy species.
