The growing beaver population in Flanders is creating tensions between conservation efforts and human interests, reports De Standaard. Local authorities are struggling to manage the impact of beaver activity, as dams are regularly removed to prevent flooding of farmland and gardens – only for the persistent animals to rebuild them overnight.
Since their illegal reintroduction in the early 2000s, beavers have spread across Flanders, with an estimated 1,200 individuals now living in the Dijle and Maas valleys. While their presence benefits biodiversity and water retention, their dam-building can also destabilise dikes and cause property damage.
The Flemish government has spent millions on water management related to beavers, prompting Environment minister Jo Brouns (CD&V) to call for clearer zoning regulations to balance conservation with stricter intervention where necessary. Relocating beavers is not considered a viable solution, as they often return or create new conflicts elsewhere.
Ecological benefits
Despite the challenges, conservationists stress the ecological benefits of beaver activity. Scientific research supports their presence and highlights the significant ecosystem services they provide. A 2020 study estimated the global value of these services at 128 million euros for habitat and biodiversity provision, 31 million euros for moderating extreme weather events and 27 million euros for water purification, among others.
The Eurasian beaver remains a protected species under both Belgian and European law, including the EU Habitats Directive (Annex II and IV). It is illegal to capture, harm or kill beavers or to disturb them or their habitat in any way. Experts argue that rather than trying to eliminate them, people need to adapt to their presence – because the beaver is here to stay.
