RubberGuard has in collaboration with authorities in Denmark, Sweden and Germany tested RubberGuard Fencing:
In Denmark: Aalborg University and Ree Park. The results of this are i.a. referenced 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.
“Our experiments show that the setup with this conductive rubber wire 20 cm above and below the traditional sheep fence, respectively, is a far 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 ", is the conclusion of the report.
