iTree Bristol & Action Plan for Bristol's Urban Forest

iTree Bristol & Action Plan for Bristol's Urban Forest

Through summer 2019, 29 volunteers worked with Anna Brunton from the charity to survey 201 iTree plots across the city: this is some achievement: thank you to all! The results are being processed through the nationally and internationally recognised iTree Eco 6 model and will shortly enable us to describe the city's urban forest and quantify the environmental and pollution management services they provide. iTree Bristol along with the recent Talking Trees: Bristol campaign, will inform the forthcoming Action Plan for Bristol's Urban Forest. This will set objectives for partners including how canopy cover can be increased in line with the One City Plan and how a much  broader range of people and organisations can be engaged in caring for in Bristol's trees.     

iTree Bristol is supported by the Forest of Avon Trust working with Bristol City Council, the Woodland Trust, Bristol Tree Forum and Forestry Commission SW. 

Taking Action for Bristol's Trees

iTree Eco Background

iTree Eco has been widely and successfully used in the USA and is a robust valuation model for the range of environmental services provided by trees. In Britain, it was first used in Torbay in 2011, with its application quickly widening and informing tree care budgets and investment decisions in cities including Edinburgh, Glasgow and London.

iTree Eco North Somerset

In 2013, North Somerset Council commissioned the Forest of Avon Trust to deliver the second iTree Eco survey in Britain and the first to use volunteers for data collection. This involved a core group of 12 volunteers surveying 169 randomly generated plots across the authority. A detailed report set out a number of important findings including that North Somerset’s trees remove harmful pollutants (CO, NO2, O3, PM10, PM2.5, SO2), with an annual average value of £1,703,650: a significant contribution to the quality of life of residents.  

The North Somerset iTree Eco study has helped make a strong case for tree care budgets at a time of significant funding cuts in North Somerset. It also provided a highly effective way for the Council to engage and galvanise local people in taking practical action to care for it’s trees.  

iTree Scope & Costs

The latest version of iTree Eco (6) generates an even wider range of data on the environmental services provided by an area’s tree and also information on tree health and predicted responses to pests and climate change. iTree Bristol will use this latest version of the model.

For local authorities iTree Eco 6 can inform decision making and financial planning at a time growing pressure on budgets and also Government requirements to manage NOx and other pollutants. It also provide a positive and effective way to engage and involve local people. For utilities, iTree Eco 6 can also further quantify the sustainability of their estate.

We are proud to have delivered iTree North Somerset and iTree Bristol, both with a strong community dimension, so please do not hesitate to get in touch by emailing:
