The triennial conference is a unique gathering of built and natural environment professionals, working towards the shared goal of enhancing green infrastructure. It provides an important platform for collaboration between professions and offers new research on the environmental, social and economic benefits of urban trees. Next year’s conference focuses in particular on two themes: health and highways. Prof Alan Simson, TPBE3 Conference Chair, commented on the significance of these subjects:
“The significant relationship between trees, people and place has been a ‘known known’ for a long time, but it is only relatively recently that research has been able to positively prove the benefits of this relationship, particularly to the places where we live, love, work, recreate and have our being. This conference will focus upon two specific yet inter-related aspects of these benefits – those associated with human health and well-being, and those associated with movement and transport. Key speakers from both overseas and the UK will be presenting aspects of their research and best practice into these important themes at this conference, which will be a significant event in promoting the benefits that trees can bring to urban futures in the 21st century.”
Confirmed keynote speakers for this event include landscape planning and public health expert, Dr Matilda van den Bosch, University of British Columbia; Prof Miles Tight, Professor of Transport, Energy and Environment, University of Birmingham; and Maarten Buijs, Senior Project Manager at internationally acclaimed Dutch urban design and landscape architecture firm, West 8.

“The Institute of Chartered Foresters is proud to host and organise the Trees, People and the Built Environment conference series on behalf of the conference partners.
