Install electric fencing to protect crops from mammals to reduce human-wildlife conflict Terrestrial Mammal Conservation

A before-and-after study in 1961–1965 in a forest in New York State, USA (Tierson 1969) found that an electric fence reduced browsing on hardwood trees by white-tailed deer Odocodus virginusnus. Three years after fence erection, there were more unbrowsed stems inside the fence (43 unbrowsed stem/plot) than outside (16 unbrowsed stems/plot). There had been no difference in browsing rates before fence erection (inside fence line: 22 unbrowsed stems/plot; outside fence line: 22 unbrowsed stems/plot). The fence (2.5 miles perimeter) consisted of five wires, with the lower three electrified from November 1961. Browsing intensity was measured in plots measuring one rod-square (approximately 25 m2). Twenty plots inside and 20 outside the fence were surveyed in 1961 and 1964.
