i-Tree Leeds: Putting a Value on the City’s Trees

June 11, 2018

As part of the Leeds4Trees project we are exploring the value of trees and green spaces across the city of Leeds, in collaboration with the United Bank of Carbon, the Sustainability Service at the University of Leeds, Leeds City Council, The Woodland Trust, Treeconomics and Forest Research.

Urban green spaces such as gardens, parks and woodlands provide many benefits to people and vital habitats for wildlife. Urban vegetation stores carbon, helping to mitigate climate change, and reduces the likelihood of flooding by storing excess rain water. Green spaces can improve air quality, limit the impact of heatwaves, encourage people to undertake physical activity and reduce depression. However, these benefits are difficult to quantify and compare to other uses of urban land.

The i-Tree Leeds project aims to provide evidence that can be used to support the preservation and creation of green space and woodland in Leeds. Last summer saw a team of volunteer staff and students survey over 800 trees on the University of Leeds campus, identifying more than 100 different species! The campus trees are estimated to store over 300 tonnes of carbon (which is over 1000 tonnes of carbon dioxide), and remove around 11 tonnes of carbon (40 tonnes of carbon dioxide) from the air every year.

This summer the i-Tree Leeds project is heading to Middleton in Leeds and we need your help! Sign up here (or at the bottom of this page) to help us survey the trees in Middleton during June, July and August 2018.

The map above shows locations and species of trees on the University of Leeds campus and some of the benefits they provide. The map has three layers: 1) Species and measurements, 2) Carbon storage and sequestration, 3) Pollution removal – you can find more information on what this map shows here.

The map is easiest to view one layer at a time. To open a larger version in a new window click on the square icon in the top right corner. To view the map menu click on the window icon in the top left corner of the map.

To enable a layer either tick the box next to the layer name (e.g. Species and measurements) or click on the layer name. The icons contained in that layer will appear on the map. To disable a layer un-tick the box or click on the layer name.

Click on a tree icon or pointer to display information about that tree. Click on a part of the map without an icon to close the tree menu, or click the back arrow in the top left corner.
