De mémoire d’arbre: five centuries through the eyes of a tree

Published 23 April 2026 By Magda Bou Dagher Kharrat

–French version below–

“My name is Adrouman and today I am 517 years old…”

This is how the extraordinary scientific novel De mémoire d’arbre opens, spoken in the first person by a Phoenician juniper (Juniperus thurifera) growing high in the Moroccan Atlas, born in the year 1505.

Over five centuries, Adrouman recounts a life shaped by relentless winters, summer droughts, the shepherd’s axe, the pressure of grazing herds and, most recently, climate change. His story unfolds as a saga that is both intimate and universal, revealing how the fate of trees and that of human societies are deeply intertwined.

Written by Thierry Gauquelin, emeritus professor at Aix‑Marseille Université and a leading specialist in Mediterranean forest ecosystems, the book transforms science into a living narrative. Free from heavy‑handed didacticism, it achieves a rare balance between rigorous botanical knowledge and genuine literary emotion.

De mémoire d’arbre is also a subtle yet powerful manifesto. It challenges us to move beyond seeing trees merely as resources or decorative elements, and to recognise them instead as co‑inhabitants of our planet—essential to our survival and silent witnesses to environmental change unfolding over timescales far longer than any human life.

By giving voice to a tree that has endured centuries of climatic extremes and human pressures, Gauquelin invites readers to rethink their relationship with forests and landscapes. His story encourages us to listen more attentively, observe more humbly, and acknowledge the deep memory that trees carry within their rings.

You will never look at trees in quite the same way again.

« Je m’appelle Adrouman et j’ai aujourd’hui 517 ans… »

C’est ainsi que s’ouvre l’extraordinaire roman scientifique De mémoire d’arbre, raconté à la première personne par un genévrier thurifère (Juniperus thurifera) perché sur les hauteurs de l’Atlas marocain, né en l’an 1505.

Au fil de cinq siècles d’existence, Adrouman nous raconte les hivers implacables, la sécheresse de l’été, la hache du berger, la dent du troupeau, et aujourd’hui le changement climatique. Une saga à la fois intime et universelle, où le destin des arbres et celui des hommes s’entrelacent profondément.

Sous la plume de Thierry Gauquelin, professeur émérite à Aix-Marseille Université et spécialiste reconnu des écosystèmes forestiers méditerranéens, la science devient récit vivant. Loin de tout didactisme pesant, ce livre réussit le pari rare d’allier rigueur botanique et émotion littéraire.

De mémoire d’arbre est aussi un manifeste discret mais puissant. Il nous invite à cesser de voir les arbres comme de simples ressources ou ornements : ils sont nos colocataires sur cette planète, indispensables à notre survie.

En donnant la parole à un arbre qui traverse les siècles et les bouleversements environnementaux, Thierry Gauquelin nous pousse à repenser notre relation aux forêts et aux paysages. Vous ne regarderez plus jamais les arbres comme avant.
