Answer for Tree felling by Transport for London

Answered By: 
The Mayor

Since 2016, Transport for London (TfL) has felled 256 mature street trees for the following reasons:

 - 172 because of natural causes, including disease, decay or death of the tree

- Eight for safety reasons

- Three due to third party claims

 - Two because of improvement schemes

- One which was self-sown (i.e. was not deliberately planted)

We do not have records showing why 70 of the 256 trees were felled, although the reasons are likely to be a combination of those above.

TfL always seeks to replace any street trees it removes. If it is decided not to replace a tree in the same location, this is generally because underground conditions mean replanting may not be possible. TfL has planted 1,105 street trees since 2016.

The recently published Mayor's Transport Strategy commits TfL to increase street tree numbers on the TLRN by 1 per cent every year between 2016 and 2025.


In addition, TfL Property Development will re-provide any trees felled during the development process on the TfL property estate at a rate of 2-to-1 (with re-provision to occur on-site where appropriate).

TfL is also responsible for managing vegetation along its rail and tram tracks. As part of this, and in order to maintain a safe and reliable network, TfL is required to remove trees to ensure they do not overhang tracks and obscure drivers' views. It also has to remove trees and leaves that have fallen on tracks.
