Trees and woodlands

Trees and woodlands

Trees and woodlands make London a healthier, more attractive place to live, and help combat climate change and air pollution.

London's urban forest contains an estimated 8 million trees and covers around 20% of the city's land area. See how we measured tree canopy cover.

The Mayor has committed to a major tree-planting programme, working in partnership with businesses, the community and the public sector.

Why we want more trees

London's urban forest is increasingly recognised for its economic value as well as its environmental and social benefits. 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 Mayor has a target in the draft London Environment Strategy to increase tree cover by 10%.

What we are doing for London’s trees and woodlands

Community Tree Planting Grants

The Mayor is funding projects through the new Greener City Fund to plant trees and woodlands in London in autumn/winter 2017/18.  A total of £400,000 has been awarded to 29 local projects across London to plant over 20,000 trees. A second funding round for Community Tree Planting grants will open in April 2018.

See this year's funded projects on our Greener City map. The Mayor also supported tree-planting projects in 2016-17.

Free trees for schools and community groups

In partnership with the Conservation Volunteers (TCV), we have made 10,000 free trees available for London’s schools and community groups this winter. These trees have now all been allocated, but we will have more trees for community groups in autumn 2018.

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 published Supplementary Planning Guidance on preparing borough tree and woodland strategies.

We promote trees as an essential part of new developments and regeneration schemes. We have worked with the Trees and Design Action Group to give developers and architects evidence of the benefits of large canopy trees in the urban environment and help them incorporate trees into urban landscapes.

See two guides:


London's 12,899 hectares of woodland come with a wide range of benefits but not all are managed sustainably. The Forestry Commission has information on looking after woodlands in London, including data on the amount of woodland currently managed in London and why we should encourage more woodland management. 


We co-ordinate the London Tree Partnership. This is aimed at protecting the capital's trees and encouraging Londoners, businesses and organisations to plant more of them. Since 2011 the partnership has supported activities including tree planting, orchard creation and community woodland events.

We promote the importance of trees and woodlands across London.

London Tree Week celebrates London’s trees with a programme of events and activities. We also host the London Tree and Woodland Awards to recognise leading projects and people who have contributed to maintaining and improving London’s trees and woodlands.

Valuing and mapping London's urban forest

We're documenting London's trees in several ways:

  • an i-Tree Eco survey of London’s trees and woodlands has measured the benefits and value of the capital's trees. In autumn 2014 over 300 volunteers surveyed more than 700 locations across London using the US Forest Service’s i-Tree methodology. The final report was published in December 2015
  • the 2015 GLA study of tree canopy cover in London (see above) used aerial imagery to offer a baseline for measuring changes in tree cover over time.  
  • our London street tree map

What can you do for trees and woodland?

Free tree packs for schools and communities are available from:

The Tree Council also offers small grants towards the cost of tree planting for schools and communities.
