Double fences built in a private conservation park to keep cattle separated from wild buffaloes, which are persistently infected by Foot and Mouth disease. The fences do not stop wildlife from roamiing because grazing animals in Zimbabwe stay put and do not migrate. Good fences, on the other hand, can protect wildlife from illegal hunting, protect natural resources and decrease the chance of Foot and Mouth disease from being transmitted between domestic livestock and wildlife. - - General: General.
