The Trees and Design Action Group (TDAG) is a unique multi-disciplinary group of individual professionals and organisations from both the private and public sectors. They have come together under The London Tree and Woodland Framework to collaborate in achieving an increased awareness of the need to bridge the practicality gap that exists between the aspirations to include trees within the built environment and the practical requirements needed to achieve this.


TDAG's objective is to create the pre-conditions necessary for trees to be considered as an integral part of development at the earliest conceptual and design stages of any scheme so that these aspirations are realised and large species long lived trees are adequately accommodated in development wherever this is possible.

The TDAG's agreed approach to achieving these pre-conditions is to publish a set of guidelines providing guidance to the various professionals who deal with trees and the built environment in the course of their work. These guidelines cover the numerous barriers and obstacles together with the solutions to achieving large long lived tree species in development.

The first of these guidelines was published on Wednesday the 26th of November 2008 at a reception held by The Tree Council at the House of Commons to mark the start of National Tree Week 2008.

These guidelines entitled "No Trees, No Future" Trees in the Urban Realm were launched for consultation and to begin the process of changing attitudes and informing the relevant professionals of the benefits of large species trees and how they may be integrated into new development.

  3. "No Trees, No Future" Trees in the Urban Realm (with Case Studies) (5184KB)


 The TDAG has sought views on these guidelines from all quarters and undertaken a wide ranging consultation process obtaining views and comments on the content, direction and effectiveness of these guidelines. The survey is now closed and the results are being collated with a view to publishing updated guidelines in November of 2009. However if you would still like to comment please contact Jim Smith following the details below.
