Stop bevers from being killed in Walibi Belgium

Bevers around the forest of theme park Walibi Belgium seem to be a threat for a nearby roller coaster. The solution which apparently is most likely to happen is killing the bevers, despite their threatened status in this region.

Another park called Pairi Daiza already has offered to relocate the bevers to their domain, so with a little bit of goodwill these bevers can be saved easily. Please help convincing Walibi's director to choose the relocation option over killing.
