Drought threatens Luxembourg’s forests

The prolonged drought and high temperatures in recent weeks have had a serious negative impact on Luxembourg’s forests. According to Martine Neuberg of the Nature and Forest Agency, many trees have begun to change colour and shed their leaves prematurely. She explained that the plants are under severe stress and have stopped supplying moisture to their leaves since June.

The effects of the drought are particularly evident in the Ellergronn Nature Reserve, located in Esch-sur-Alzette. The local forester, Paul Zimmermann, noted that the problem had become apparent as early as late spring. The springs that previously fed the marshes and ponds within the reserve have stopped flowing. Combined with intense evaporation, this has led to a critical drop in water levels in the natural water bodies.

Experts warn that, due to heat stress and water shortages, trees are losing their ability to perform their vital functions to the full. As a result, they provide less shade and produce less oxygen. Martine Neuberg emphasised that the slowdown in forest growth will inevitably lead to a reduction in oxygen production in the future. Experts view these processes as direct long-term consequences of climate change. The current situation is assessed as being significantly more severe than last year’s, and forecasts suggest that tree growth may slow down further next season.

Despite the seriousness of the climate threat, representatives of the Nature and Forest Agency believe that panic is not a constructive strategy. The agency’s experts are currently using the data they have gathered to develop a programme to help forests adapt. The aim of these measures is to ensure the conservation of the ecosystem and its ability to provide vital natural resources for future generations.
