Trees and woodlands

London is one of the greenest cities in the world.  Trees and woodlands make London a more attractive place and also help combat the effects of climate change.

It is estimated that there are about 8 million trees in London, and about 20 per cent of London is covered in trees.  The Mayor has a target to increase tree cover by a further 5 per cent, to 25 percent, by 2025.

Why we want more trees

Increasing the number of trees is at the heart of the Mayor's vision to help make London greener, cleaner, more welcoming and more resilient.

The value of London's urban forest

London's urban forest is increasingly recognised as having an economic value thanks to its environmental benefits. An i-Tree Eco survey of London’s trees and woodlands will help to establish the benefits they provide and to put a value on the capital's trees. In the autumn of 2014 over 200 volunteers surveyed trees in more than 700 locations across London using the US Forest Service’s i-Tree methodology.  The i-Tree data from the survey is currently being analysed. A report will be published online in autumn 2015.

Smaller areas of London have already looked at the benefits of their trees. We worked with Victoria Business Improvement District on a report which assesses the benefits of trees and other green infrastructure. This uses the i-Tree and CAVAT models to assess the value of Victoria’s trees.

What are we doing for London's Trees and Woodlands?

Community Grant Scheme

  • The London Tree and Woodland Community Grant Scheme provides grants of £2,000- £10,000 to projects which promote or protect trees and woodlands and engage local communities. Read more here.

Policy development

  • The London Plan provides a policy framework which encourages the protection and maintenance of trees and the planting of new trees and woodlands. We have also published Supplementary Planning Guidance on Preparing Borough Tree and Woodland Strategies (2013).

  • We also promote trees as an essential part of new developments and regeneration schemes.

  • We have worked with the Tree and Design Action Group to provide developers and architects with the evidence of the benefits of large canopy trees in the urban environment and also how to incorporate trees into urban landscapes. See The Canopy (2011) and the Trees in Hard Landscapes (2014) guides. 


  • The Mayor leads the RE:LEAF Partnership which works to protect the capital's trees and encourage individual Londoners, businesses and organisations to plant more trees. The partnership has supported a range of activities since it started in 2011, including tree planting, orchard creation and community woodland events.

Planting trees

  • We have planted 20,000 street trees across London under the Mayor’s Street Tree Initiative.  

  • We have also supported over 60 community projects through the London Tree and Woodland Community Grant Scheme since 2012, which has resulted in over 8,000 trees being planted as well as engaging over 8,000 children and adults in the projects.

  • We have worked with the RE:LEAF Partnership on tree planting events, resulting in over 100,000 trees being planted.




  • We promote the importance of trees and woodlands across London. We have established London Tree Week in May, which is a week when we celebrate and appreciate London’s trees with a week of events and activities.

  • We also host the London Tree and Woodland Awards which recognise leading projects and people who have contributed to maintaining and improving London’s Trees and Woodlands.

What can you do?

  • Plant a tree! The Woodland Trust offer free trees for schools and community groups. The Tree Council also provide small grants towards the cost of tree planting for schools and communities.  

  • If you’d like to help improve our data about tree cover in London, you can follow these instructions to estimate the tree cover in your neighbourhood.

  • Download the 'Tree-Routes' app (for iphone/ipad) built in partnership with the Woodland Trust.  The app lets you see trees of interest across London by borough or tube line.
