i-Tree Eco

Home Research i-Tree Eco

This project aims to facilitate the use of i-Tree Eco in the UK. i-Tree Eco is a software application which is used to quantify the structure and environmental effects of urban trees and calculate their value to society. Data from an i-Tree Eco survey can be used for making effective resource management decisions, developing policy and setting priorities for a town’s trees and greenspaces.

Forest Research have entered into a Memorandum of Understanding with Treeconomics and the Arboricultural Association to deliver the “i-Tree UK” project, which has four main objectives:

  • manage a development strategy for i-Tree tools in the UK
  • collate and store data from i-Tree studies undertaken in the UK
  • gather and share information about the value of the UK’s urban trees
  • promote i-Tree in the UK and help other organisations and individuals to make maximum use of i-Tree study data and reports.

Together, we are working with the i-Tree Cooperative to develop full functionality of i-Tree Eco within the UK and facilitate its use and uptake by UK users.

The i-Tree Cooperative comprises the US Department of Agriculture (USDA) Forest Service, Davey Tree Expert Company, International Society of Arboriculture, Society of Municipal Arborists, Arbor Day Foundation, and Casey Trees.


The programme started in 2013 and is ongoing.

Research objectives

Our work is focussed around:

  • Working with Treeconomics and the Arboricultural Association to deliver the “i-Tree UK” project
  • Working with Treeconomics to deliver i-Tree Eco surveys to parks, highways, towns, cities and community forests within the UK
  • Supporting individuals, charities and small organisations to deliver their own i-Tree surveys in the UK
  • Undertaking scientific studies to test and improve the assumptions and calculations contained within the i-Tree Eco model

Latest updates

  • Project partners in the delivery of the UK’s first i-Tree Eco study in Torbay
  • Delivery of the i-Tree Eco studies for Bridgend, Cardiff, Edinburgh, Glasgow, Newport, Petersfield, Southampton, Swansea and Tawe Catchment, and Wrexham. See i-Tree Eco Projects Completed for more information.
  • Project partners in i-Tree London
