Luxembourg is expanding its list of ‘notable trees’

The Ministry of the Environment, Climate and Biodiversity, in collaboration with the Nature and Forestry Agency, has launched a campaign to mark International Tree Day. Under the slogan ‘Eis Beem loosse sech weisen!’ (‘Our trees will surprise you!’), the authorities aim to draw attention to the ecological and cultural value of the country’s oldest and most unusual trees. Minister Serge Wilmes emphasised that these trees are not merely elements of the landscape, but key allies in the fight against climate change.

To date, around 240 trees in the Grand Duchy have been officially designated as ‘remarkable trees’ (arbres remarquables). To qualify for this status, a tree must possess exceptional dendrological characteristics: impressive size, unusual morphology, or historical and commemorative value.

Remarkable trees are recognised as self-sustaining ecosystems. Their hollows, bark and root systems provide a habitat for a wide variety of plant and animal species. Furthermore, they act as a natural cooling system in urban areas.

The status of a ‘notable tree’ entails enhanced legal protection. It is prohibited by law to:

• Cut down or uproot such trees.
• Move or damage them.
• Destroy them without special ministerial authorisation, which is granted only in exceptional circumstances (public necessity or phytosanitary reasons).

A key feature of the 2026 campaign is a call for the public to take part in the inventory of natural heritage. Until 31 October 2026, any resident of Luxembourg can nominate a tree (whether on public or private land) for inclusion on the conservation list via the arbresremarquables.lu portal. Each application will be assessed individually by experts from the Nature and Forests Department.

To encourage landowners to preserve such trees, the government is offering substantial financial incentives. Under current regulations, the state may reimburse up to 75% of the costs of professional care and conservation of ‘outstanding’ trees.
