Abstract: A device to prevent incursion of wild elephants into human populated areas, and thereby protect the lives of both wild elephants and humans living in close proximity to elephant refuges, is disclosed. The device incorporates a series of rollers that discourage an elephant from crossing the device. Multiple units may be linked together to form a barrier of any desired length. The border on the frame of each unit is protected by a guard that pinches the foot of an elephant attempting to cross over on the butted edges where two units meet. Alterative embodiments of the device may include roller protrusions, a chemical repellent dispersant, and an electrified conductor wire.
