The trees in our urban parks, gardens, housing estates, open spaces, woodlands, streets and transport infrastructure are collectively described as an ‘urban forest’. This report provides the most comprehensive study to date on the structure and value of the urban forest across a political geography: the London Borough of Ealing. At the time of publishing, the project is unique in implementing a combination of the i-Tree assessment methods: random sample i-Tree Eco, council inventory i-Tree Eco, and i-Tree Canopy.
