The installation of electric fence is an effective and relatively inexpensive way to prevent black bears from entering large areas such as landfills, agricultural sites and apiaries. Electric fence is easy to install and, although it requires some regular maintenance, is the most effective bear barrier for large areas.

this 10 acre Ramara Township
corn field is powered by a
which can provide a 7000
+ volt charge over several
kilometres of multi-wire fence
line. Crop depredation was
severe at this site in 2003
and in 2004. In the fall of
2005 the fence was erected
to protect the farmer's field
against black bears and other
wildlife. Initial results indicate
that electric fencing works and
is a viable tool in protecting crops. Photo by: Jeff Schosser, Ministry of Natural Resources
Install electric fence early in the season so that a bear receives a strong, negative experience the first time it attempts to access the area. It is much easier to keep bears away from an area if they receive a shock before they have a successful feeding experience. Bear activity in landfill sites typically peaks in July and August but may extend for months prior to and after that period.
In cases where there is no apron installed and bears dig an entryway beneath the fence, filling in of entry points and other low spots along the fence line with large cobble (15 - 30 cm stones) or logs may be required. Electrified ground mats can also be placed at entry points or spots where the bottom strand is higher than the recommended 5 cm, to deter bears from trying to dig or crawl under the fence at these points. An additional strand of charged wire running out 12 - 18" (30 - 45 cm) from the fence, and 8 - 12" (20 - 30 cm) above the ground can increase the change of a bear receiving a shock if it attempts to dig under the fence. These measures should be implemented immediately if bears gain entry to the fenced site.
