During Summer and Autumn 2018 City of Trees completed the biggest i-Tree Eco survey outside the United States, with the aim of quantifying the value of Greater Manchester’s trees and woods.
Delving deep for data
Data such as such as tree species, width, height and diameter were collected from more than 6,000 trees across Greater Manchester by a team of 57 surveyors who visited nearly 2,000 plots.
The data was fed into the i-tree software system, which processed the information to provides insightful results about the economic value of trees, trees under threat and where there is potential to plant more.
Headline results
The key results are as follows:

This data will be used to protect existing trees, as well as identifying new land for planting – assisting with initiatives such as The Northern Forest and the Greater Manchester Spatial Framework - providing guidance for planners and developers.
The results form part of All Our Trees: Greater Manchester's Tree and Woodland Strategy which can be found here.
