New suite of publications explores services provided by urban trees

Urban trees are increasingly recognised for the services they provide to support sustainability and quality of life in our towns and cities.

Now a newly published suite of Forest Research publications investigates how the services provided by urban trees, such as the capture of carbon, and flood risk reduction (so called ‘ecosystem services’), varies with the stature and age of trees common to the urban environment of Great Britain.

The publications detail how large and medium sized tree species provide more environmental and social benefits than small tree species.  However, they also explain that small and medium sized trees are important for adding species and structural diversity, as well as providing ecosystem services in areas where large trees are unsuitable.

By drawing on the various qualities of different species, the documents detail how managers can use urban trees to meet multiple objectives such as providing climate cooling or reducing the chances of flooding as our climate changes.

The suite consists of two Research Reports, one focussed on large stature tree species and another on small and medium stature trees.  They discuss the provision of four services (carbon storage, carbon sequestration and avoided storm water run-off) over the lifetime of a range of tree species, based on calculations incorporated within software tool i-Tree Eco.

There is also a Research Note which summarises the provision of these four services by 30 tree species common to the urban environment in the UK.  Drawing upon a review of Local Authority tree strategies, it reveals the implications of management practices for the delivery of these services by individual trees.

The publications aim to inform species selection for future tree planting, as well as the preparation of local authority urban tree management plans.  They complement DEFRA’s Urban Tree Manual which provides advice on selecting and procuring the right tree for the right place in urban areas.

The reports are available to download from the Forest Research website:
