RubberGuard has in collaboration with authorities in Denmark, Sweden and Germany tested RubberGuard Fencing:
In Denmark: Aalborg University and Ree Park. The results of these tests are referred to in Aktuel Naturvidenskab, Århus Stiftstidende and TV2MidtVest.
In Sweden: Several County Administrative Boards and the University of Agriculture, SLU, in Uppsala.
In Germany: Landesschafzuchtverband Baden-Württemberg and Landesamt für Landwirtschaft, Schleswig-Holstein and NABU-Naturschutzstation Münsterland.
The wolves can get both under and over the wolf fences, which just have to keep the wolves away. At least if you build according to the Danish Environmental Protection Agency's recommendations with a height of 90-100 centimeters and with low voltage. This is shown by the experiment and thesis study that the researchers from Aalborg University conducted with Ree Park's wolves in Djursland. The wolves' forcing of the fence has been documented with a number of pictures, where the wolves easily both jump over and go under the fence.
“Our experiments show that the setup with this conductive rubber wire, 20 cm above ground and below the traditional sheep fence, is a much better protection against wolves than the traditional fence alone. We recommend a fence height of 115-145 cm as a more effective fence against wolves ", the report reads.
