Ealing i-Tree Eco: Valuing Ealing’s Urban Trees

Project description: 

The Ealing i-Tree Eco project provides a comprehensive study on the structure and value of the urban forest across the London Borough of Ealing. In 2017, Ealing Council partnered with Trees for Cities, Treeconomics, Forest Commission, Forestry Research and the Greater London Authority to deliver London’s first borough-level i-Tree Eco project. The i-Tree Eco tool has been developed to help quantify and value some of the environmental benefits provided by urban trees. This project calculated the impact urban trees had on pollution removal, carbon storage & sequestration, and storm water alleviation. The total annual benefits of Ealing Borough’s trees were estimated at £1.6 million. This detailed account of Ealing’s trees provides relevant information and recommendations to inform the council’s tree strategy in the short, medium and long-term and provides the baseline information for ward level comparisons.
