Answered By: 
The Mayor

Transport for London (TfL) has an extensive tree-planting programme. Over the last five years it has planted 4,753 trees and removed 2,977 – a net gain of 1,776 trees.


Street trees sometimes need to be removed. The primary reasons for this are natural causes (such as death, disease, decay) and highway safety. Some trees are also removed as a result of schemes or developments.


In 2016/17, Transport for London (TfL) removed 757 street trees and planted 1,173 street trees – representing a net gain of 416 trees.


In 2017/18 TfL removed 632 street trees and planted 339 street trees, representing a net reduction of 293. TfL undertook a major restructure of its assets teams in 2017/18, which has created a more efficient and effective operation. Owing to the amount of change, TfL prioritised safety-critical work and did not undertake as much planting as normal.


Overall, this represents a net gain of 123 trees from 2016/17 to 2017/18. These figures, however, do not account for new trees planted as part of improvement projects, which, as explained in my response to Mayor’s Question 2018/2106, account for a significant proportion of new trees planted by TfL. TfL is putting in place processes to capture this information.
