New citizen science project will help identify the benefits of city’s urban forest
Experts from Anglia Ruskin University (ARU) are working in partnership with Cambridge City Council, Treeconomics and Forest Research to carry out the i-Tree Eco survey – a new citizen science project to identify the benefits provided by the city’s trees.
Cambridge has over 300,000 trees, which have a positive impact on the city’s environment benefiting residents, visitors and wildlife. The i-Tree Eco survey will help describe and quantify these benefits, enabling better management of the trees and support future investment in the city’s urban forest.
A similar project carried out in London discovered that trees within the area of Ealing Borough Council provided benefits to a value of £1.6 million per year. It was found they help to reduce flood risk, improve air quality, store carbon, boost biodiversity and enhance health and wellbeing.
The i-Tree suite of tools were developed by the US Department of Agriculture’s Forest Service and have been adapted for use in the UK. The Cambridge study was initially going to involve 20 students from ARU’s School of Life Sciences carrying out the surveys across the city.
Due to COVID-19, the i-Tree Eco survey will now go ahead as a collaborative and innovative citizen science project, with the organisers hoping to engage at least 135 Cambridge households. Participants will be sent guides to help them determine the type and size of trees and other vegetation in their own gardens.
Staff and student volunteers from ARU will be involved in additional surveying work once social distancing restrictions have been lifted.

This i-Tree Eco survey is part of the Cambridge Canopy Project, a Council-led initiative which aims to help Cambridge prepare for the projected impacts brought about by climate change by protecting and enhancing the city’s urban forest.
