The Beverbos is a nature reserve in the province of Flemish Brabant in Belgium, located along the Maalbeek between Wemmel and Strombeek-Bever. The name Beverbos refers to the hamlet of Bever and the Hof te Bever, which are located along the Maalbeek valley. The Lees(t)beek flows into the Maalbeek on the southwestern edge of the forest.
The Beverbos consists largely of alder swamp forest, marshland with reed beds and marshy meadows. The marshy soils are kept wet by sources with clear, calcareous water, which is why the area was considered unsuitable for arable farming in the past. As a result, the area has managed to retain vegetation including arum, marsh marigold, yellow iris, water plantain, bur-reed and Solomon's seal.
Various species of amphibians can be found in the marshy areas, such as the brown frog, common toad, alpine newt and common newt. The reed beds provide shelter for the grasshopper warbler and the marsh warbler. The higher wooded areas are home to woodpeckers, birds of prey such as buzzards and hobby, and various species of small songbirds. A relative newcomer is the ring-necked parakeet, an exotic species that competes for nesting holes with native breeding birds such as nuthatches and woodpeckers.
The forest has been managed by Natuurpunt since 2003 and is part of the "Green Corridor" project with which the province of Flemish Brabant wants to work on nature restoration and nature connectivity in the northwest of the province.
