Definition of tree for planning purposes
Tree preservation orders (TPO’s) can be used to prohibit the cutting down, uprooting, topping, lopping, willful damage to, or willful destruction of protected trees or woodlands. This applies to roots as well as stems and branches.
In addition, in conservation areas, the cutting down, lopping or topping of trees must be notified to the local authority 6 weeks in advance so they can consider whether the tree contributes to the character of the conservation area and whether to impose a tree preservation order.
In the case of Palm Developments Ltd v Secretary of State for Communities and Local Government in 2009, Mr Justice Cranston took an amazing 12,000 words to consider the issue. He decided that “There is no statutory definition of a tree. I conclude that with tree preservation orders there are no limitations in terms of size for what is to be treated as a tree. In other words, saplings are trees… “Tree” must therefore mean anything that would ordinarily be regarded as a tree. Thus it would not include a shrub, a bush or scrub.”
This represents a change from a previous judgment by Lord Denning MR in the Batchelor case, who concluded “..many saplings were not trees and would need to be of over 180-200mm diameter before they could be…”.

- where a tree has more than one stem at a point 1.5 metres above the natural ground level its diameter shall be treated … as exceeding 75 millimetres or 100 millimetres respectively, if any stem when measured over its bark at that point exceeds 75 millimetres or 100 millimetres respectively; and
