Luxembourg's trees are in danger

Sooty bark, caused by the fungus Cryptostroma corticale, is found in many areas of Luxembourg, including parks, forests and road plantings. The southern and eastern regions are considered to be the most affected, but accurate data on the extent of the lesion is not available due to the difficulty of monitoring. The distribution of maples in forests makes mapping and tree counting problematic.

For the majority of the population, the threat is minimal: short stays in areas of contamination do not cause serious problems. However, forestry workers face the risk of respiratory illness from prolonged contact with fungal spores. They are advised to use FFP2 masks and protective clothing.

Cutting of infected maples requires prior verification of the need for a permit from the Ministry. Basic precautions include:

• Carry out work in wet weather to minimise the spread of spores.
• Use of protective equipment, including masks and overalls.
• Mandatory disinfection of tools and washing of clothes after work.

Special attention is paid to trees near crowded places and infrastructure - here additional safety measures are applied.

The State Administration of Nature and Forests provides municipalities with logistical assistance in the management and disposal of infested trees. However, the document does not mention direct financial subsidies.
