A cedar threatened by a development project: the mayor listens to a local movement

For two hundred years the Imperial Cedar had needed nobody. In February 2021 a building scheme was enough to make it vulnerable: a bicentenary tree in France enjoys almost no protection of its own. What saved it that year was not a rule of law but a movement of neighbours — and a mayor who chose to listen to them.

February 2021: the idea of some financial advisers — a municipal building where the cedar stands

The scheme covered the plots at 11 and 15 rue de la République in Meudon: two adjoining parcels brought together for a new building. The cedar stands on the first of them, and the project drawings place it exactly where the storeys of the new block were to rise. The argument put forward was not density but safety: the tree was said to be diseased, therefore dangerous, therefore doomed.

The section says what matters: there was no room for both. A cedar of Lebanon of this size occupies a volume that cannot be moved, and its roots reach far beyond its crown — under what would have become the building site. Keeping the tree meant redrawing the scheme; felling it required only a consent.

Word travelled quickly through the neighbourhood and then well beyond it. What might have been settled in silence became a public matter: neighbours and whole families refused to accept that the oldest witness on the street could come down in a single morning.

A remarkable tree with almost no protection of its own

One thing here surprises most people. In France a remarkable tree is not protected in its own right: the law does not recognise it the way it recognises a monument. It protects the tree only indirectly, through the land it is rooted in or through a decision that names it expressly.

The first instrument is the town's own planning document, the plan local d'urbanisme. That document can designate ground as an espace boisé classé — classified woodland — which bars any change of use that would compromise the survival of the trees on it. It can also identify one particular tree as an élément de paysage à protéger, a landscape feature to be preserved, under the code de l'urbanisme: works liable to destroy it must then be notified in advance. The second instrument is rarer: classification as a monument naturel under the law of 2 May 1930 on natural monuments and sites, a heavy procedure reserved for cases of manifest public interest.

A local movement, and the unexpected reaction of a mayor

When the idea came up of doing something to save the Cedre Imperial, someone who had tried, without success, to save something beautiful in nearby Ville-d’Avray replied: « je te souhaite bien du courage » — which is French for good luck with the impossible.

Instead of protest marches and political fights, hundreds of children began drawing the tree. The drawings were posted on Instagram, and some were pinned to the railings of the rue de la République.

At the same time the internet domain cedreimperialmeudon.com was registered and the history of the tree was written down. The most fascinating part came from a former resident of Meudon: a Brazilian Second World War secret service agent who had left this world a decade earlier.

Aimée de Heeren had passed on her love of the cedar to someone two or three generations younger. Not only her love of the tree, but its remarkable wartime story too — that is chapter 4.

Contrary to what many expected, Denis Larghero, mayor of Meudon, listened to the voice of those who loved the Cedre Imperial. He took the decision to keep the tree in place: the building project of his advisers was withdrawn.

A few years later, in March 2026, many friends of the cedar, grateful that the tree had been protected, voted for Denis Larghero — re-elected in the first round with 64.80% of the vote.

Summer 2026: a new problem appears, one the editor of this website had not measured until then — the effect of a concrete slab on the roots. That is chapter 8.

4. 2021

   No legal status of its own is attached to the tree, which is what the campaign had asked to see put in writing.

   The sealed ground around the trunk becomes the main threat — the subject of chapter 8.

2021: the decision, and the jewellery that followed

It is worth being precise about what that decision changed. It stopped the felling: the scheme did not go ahead at the tree's expense, and it acknowledged, in effect, that this cedar belongs to the heritage of the town and not merely to the law of the land it stands on. But it gave the tree no status of its own — and a decision can be reversed, a council can change, a plot can be sold again.

The echo of that victory carried well beyond France. The Swiss artist and jewellery designer Stephanie von Fürstenberg created a collection in honour of the cedar with the Munich house Kaddick Goldschmiede, and her postcards were distributed in Swiss post offices. A tree from Meudon thus found itself worn on a lapel and slipped into the letters of an entire country.

This is where 2021 leaves a question open. The movement was asking for two things: that the tree should not be felled, and that it should be written down somewhere. It won the first. The second is still outstanding, and it is the only one that protects beyond a single term of office. A cedar saved by a decision remains a cedar whose survival depends, every year, on somebody choosing to remember it — and the state of the ground around its trunk shows that remembering, on its own, is not enough.
