​Two consultations came out at the same time, one for the revised National Planning Policy Framework (NPPF) and the other for the Design and Placemaking Planning Practice Guidance (DPPPG). This second document is intended to replace the National Design Guide and National Model Design Code.

TDAG Newsletter – March 2026
​​
​This includes TDAG events and activities; events organised by others and an extensive list of new publications and research. We would like to encourage more research dissemination and so are introducing a ‘Research Round-up – Implications for practitioners’ inviting researchers to tell us about their completed projects and why they are relevant for practitioners working with trees. Please submit a short outline here

Trees, People and the Built Environment 6

​This will take place in June 2027, but we need to start planning now. Co-design is high on our agenda to develop an event that is informative across the trees and built environment professions and so we are starting with this
short survey.

Futurebuild + UK Construction Week
– ExCel 12-14 May


​TDAG has a stand (F92) close to the Placemaking seminar stage and there are two TDAG seminars on 13 and 14 May. Tony Kirkham and Kenton Rogers will lead a local tree walk on 12 May from 12.30-1.30pm.
 

Entry to the event is free. Registration. 
The full knowledge programme.

Podium planting – our latest case study is available now

​Podium planting may be the only way to achieve green space in denser urban environments.

​This 
case study from the City of London explains how it can be successfully achieved, ensuring new trees grow to a healthy maturity, to the benefit of the local area and its community.
