About TDAG

The Trees and Design Action Group (TDAG) is an open collaborative forum facilitating cross-sector and cross-disciplinary dialogue and projects promoting the role of the urban forest throughout the United Kingdom.

The group shares the collective vision that the location of trees, and all the benefits they bring, can be secured for future generations through better collaboration in the planning, design, construction and management of our urban infrastructure and spaces.

Established in 2007 as a not-for-profit and apolitical collaborative forum, TDAG incorporated as a charitable trust in 2013. Its membership, online publications and information are free. This approach enables TDAG to assimilate ideas and knowledge independently of organisational hierarchy, profit or commercial interests.

What we do

We provide a forum for cross-sector working
TDAG meets regularly in several locations which, to date, include London, Birmingham and Exeter. It is understood that all members cannot attend every meeting, but all are kept fully informed through meeting notes. The focus of each meeting is driven by the membership. For details of upcoming meetings in London, the Midlands and the Southwest do not hesitate to contact the local TDAG coordinators.

We produce best practice guides
TDAG uses its membership’s broad expertise and experience to develop guides offering evidence-based information, practical advice and case studies to inform decision-making on urban trees.

We respond to consultations
TDAG responds to consultations on policy documents as well as best practice standards and guidance that can have an impact on the urban forest. All members are invited to contribute, allowing a holistic and balanced response. All TDAG consultation responses can be found under Other downloads.

We facilitate knowledge and research dissemination
TDAG helps identify and promote available reports and research that can inform better decision making on urban trees. It also seeks to identify knowledge gaps and how they can be addressed. For more details visit our Research page.
