How can planning help us increase our urban trees?
National planning policies and the Environment Act support the role of urban trees. But this needs to be turned into action on the ground. This session will look at how this can be achieved by developing tree strategies that deliver, by demonstrating the financial and other values that trees provide and by understanding that issues such as density do not have to be a barrier to incorporating urban trees in development projects.
Maria Dunn, MRTPI | Head of Development Policy | Planning and Development | Inclusive Growth, Birmingham City Council.
Wholistic planning for trees – how to make it deliver
Anne Jaluzot, Green Infrastructure Planning Consultant and lead TDAG researcher and writer.

The critical role of trees in making healthy places that support mental and physical wellbeing
The pandemic has demonstrated the vital role of trees and green spaces in supporting peoples’ physical and mental health. Evidence tells us that the most common diseases are the non-communicable ones such as obesity, heart disease, type II diabetes and, very significantly, mental health issues of various kinds. If more people are going to be living in cities, then part of urban resilience is ensuring that these are places where people can thrive. This session looks at some of the issues and the changes needed.

Understanding the value and fragility of ‘soil’
Our ‘soils’, along with water, are one of our most valuable resources. Sadly, we have allowed our soils to be depleted, not just in our agricultural practices but more generally including in our towns and cities. If we want urban trees to grow then we must provide a healthy growing medium within the best tree rooting environments we can create. Section 3.1.4 of Trees in Hard Landscapes dispels the ‘topsoil myth’ and also emphasises the importance of using existing soil where fit for purpose as opposed to the environmental harm of importing soil. Soil is also a front-line contributor to carbon sequestration and mitigating climate change. This session invites experts in the field to explain why caring for our soil is so vital.

5th April 2022. How can we deliver and maintain trees in highways successfully?
Street trees have a crucial role in climate resilience, water quality and surface water management, traffic calming, sustainable travel and more. The National Policy Planning Framework calls for all new streets to have trees (Clause 131); the National Model Design Code identifies many situations in which street trees are included in placemaking; Homes England’s Streets for a Healthy Life demonstrates the importance of trees. Manual for Streets has been revised and TDAG is leading on the production of technical guidance and drawings to show how trees can be planted in a variety of new and retrofit situations. On the other hand, cash and time pressed highway officers are concerned that the retention, integration and management of trees diverts attention from their primary tasks and impacts on their budgets.
How do we break this impasse? How do we empower and inspire all those engaged with trees and highways to embrace the valuable role that trees play and the many benefits they deliver? How can we ‘bust’ some of the cost concerns and resolve the thorny issue of commuted sums and what they could and should be as part of national guidance? This session will explore some of the issues so that we move from ‘can’t be done’ to ‘can be done’ … and ‘we want to get it right for the long term’.
Hen Abbott, Principal Development Coordinator, Economy, Environment and Infrastructure, Gloucestershire County Council (confirmed).
Why healthy streets are a good starting point
