" Common Sense Risk Management of Trees" is guidance issued by the National Tree Safety Group. This guidance proposes that tree owners should take a balanced and proportionate appraoch to tree safety management.


The requirement under health and safety legislation is to have a suitable and sufficient risk assessment, and to apply measures that are reasonable and practicable. Courts will always ask whether a tree owner has acted as "a reasonable and prudent landowner". Because trees present a very low risk to people, owners and managers should be able to make planning and management decisions by considering how trees fit into a particular local context and avoid unnecessary intervention, survey and cost. This approach will help them ensure that any management is proportionate and strikes an appropriate balance between the real risks and benefits. Although a landowner has responsibilities for the health and safety of those on or near the land, he/she is not expected to guarantee that the tree is safe. It should be noted that the HSE has stated that "for trees in a frequently visited zone, a system of periodic proactive checks is appropriate".


A reasonable and ablanced approach forms the basis of a tree safety strategy for sensible tree safety management. By a "strategy", we mean a plan that guides management decisions and practice, in a reasonable and cost-effective way, typically covering three essential aspects:

High use zones are used by many people every day on where people or property may be affected.

Low use zones are used infrequently and may only require irregular inspection if at all.


There are three types of inspections:
