The beaver has done well in Luxembourg.

According to the results of the national monitoring carried out in the winter of 2021, the environmental authority notes that the beaver population in Luxembourg is doing very well.

Beavers do well in Luxembourg. This is an observation made by the Nature Conservation Authority following a winter 2021 monitoring nationwide. About twenty years after the discovery of the animal’s presence in the Grand Duchy, the population has not stopped breeding since 2019. The results of this study show that 80 beaver territories have been mapped across the country. And the conservation authority wants to be optimistic, explaining that “there may be other beaver habitats in Luxembourg that have not yet been discovered.” The rodent has spread to the margins of the country’s main water bodies (Haut-Sur, Alzette, Aisch and Utter) and may continue to spread.

The Department of Nature notes that this is the so-called “keystone” species. By their presence, the beaver can have a very positive impact on the aquatic habitat of Luxembourg and on the animal and plant species that depend on them. Thanks to their constructions on small streams, these mammals manage to create new ponds or wet meadows, i.e. habitats that may be occupied by rare and protected species of animals and plants. Through these dams, beavers also contribute to climate protection, as the wetlands thus created act as carbon reservoirs.

What to do in case of conflict with human interests

Like other species such as the raccoon, raccoon dog or fox, the beaver can also come into conflict with human interests. In these cases, the Conservation Authority recalls that, in cooperation with representatives of all interested groups, an action plan and management plan for the management of beavers in Luxembourg has been developed. This plan allows you to anticipate and solve the problems associated with this animal, while ensuring its protection.

History of the beaver in Luxembourg

Man pursued, hunted, and finally exterminated the beaver of the Grand Duchy for its fur, meat, and beaver fat (a glandular secretion believed to have stimulating and healing properties). This mammal reappeared in the area due to several reintroduction projects in Belgium, northern Eifel, Saarland and along the Upper Moselle (France) in the 1980s and 1990s Individuals migrated to Luxembourg and small populations settled there about ten years ago .

In these two years, the beaver is forced out of the parental territory and goes to populate a new territory. These young animals can often travel 20 to 40 km or even more than 100 km before settling down. They prefer places where there is water and vegetation. These migrations usually take place in May.

Beavers are rather cautious in summer when they are content to eat grassy vegetation. When vegetation recedes, beavers cut down more trees to get to the thin canopy branches that they eat. Therefore, their presence at this time of the year is immediately noticeable.
