Preparing to search
In summer 2021 Forest Research worked with Derby City Council to undertake an i-Tree Eco survey in the city.
Derby has 17 electoral wards. 350 sample plots were laid out across the city, to enable analysis of the urban forest in each ward.
At each plot surveyors recorded data about the trees, shrubs, ground cover, and land use. Using the field data and i-Tree Eco v6 we assessed the composition and structure of Derby’s urban forest. We analysed species diversity, risks from pests and diseases, and the range of tree ages in the city. i-Tree Eco enabled us to calculate the ecosystem services provided by Derby’s trees.
We calculated the CAVAT value of Derby’s trees, to estimate the value of the amenity provided by the trees to people in the city.

Surveying of over 300 plots was completed in September 2021. Data processing and analysis has been completed, and the final reports are now available in the Downloads section on this page.
