A new system is being tried London which will put a value on trees. Trees will be assessed on a number of factors including size, how many people enjoy the tree and the life expectancy of the tree. Taking into account all of those factors a plane tree in central London has recently been valued at £750,000. The system is designed to make it harder for trees to be felled. For example if a developer illegally destroys a tree, then the fine imposed could now be a better reflection of the tree’s value, meaning they should be less likely to consider felling a tree in the first place.
