Trees and Design Action Group
Trees touch every part of our lives – from air and water quality, temperature comfort, flood prevention to public health, wellbeing, safety, commerce and property values or road safety… These are the foundations of healthy, vibrant, resilient places. Enhancing collaboration and collective expertise on the use of trees to build a legacy of great 21st century cities is behind everything we do.
Established in 2007 as a not-for-profit and apolitical collaborative forum, the Trees and Design Action Group (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.
