Tree Architecture and Morphophysiology Symposium

Tree Architecture and Morphophysiology Symposium

Royal Botanic Gardens, Kew, London

Monday 7th and Tuesday 8th April 2025

Tree architecture was first described in the 1960s following research on trees and plants across the globe by Francis Hallé and colleagues, and has become established and well-respected in the French-speaking world, but less known in the UK. We are thrilled to welcome Francis and other experts in this field to explain how this approach to understanding tree growth can inform tree management.

We are particularly excited to introduce Jeanne Millet, the renowned author of the seminal book about tree architecture, which has just been translated into English: The architecture of trees in temperate regions - its history, concepts, and uses. We’re honoured to be launching the English translation of Jeanne’s book at this event! Copies will be on sale here for the very first time.

Tree morphophysiology has evolved from tree architecture and can be defined as ‘the study of tree shape and structure in relation to function to achieve the goal of sustaining life’.

Tree architecture and morphophysiology introduce an arboricultural language which enables users to communicate in a clearer way, with more predictable outcomes, that is designed to help promote the condition and prolong the lifespan of a tree. Using this language and its models, arborists and those specifying pruning operations can understand each other’s objectives, resulting in better tree work.

We’re pleased to provide an opportunity to delve into this refreshing view of tree growth, response and behaviour, above and below ground, with implications for managing trees at all stages of life:

  • Tree nursery production and establishment
  • Formative pruning
  • Maintenance pruning
  • Mature and veteran tree management
