Fences are the primary measure to reduce wildlife-vehicle collisions, but it is not always possible to fence over long distances, especially not in multi-functional landscapes. Side roads, driveways, and access points to agricultural fields all result in gaps in the fence. In some cases, wildlife guards or gates, are installed at access points. However, gates typically require people to get in and out of their vehicle and they are often left open. Wildlife guards are typically only suited for low traffic speed, and while they can be a substantial barrier to ungulates, they are readily crossed by species with paws, including bear species. Electrified barriers embedded in travel lanes can be a substantial barrier to both ungulates and bear species, are suitable for higher traffic volume and speed, but the costs can be up to several hundreds of thousands of dollars per location. We explored the potential for low-cost electrified barriers designed for low traffic volume and low speed as access points to agricultural fields. We investigated their effectiveness in keeping black bears out of a fenced melon patch. There were 4 access points for farm vehicles to the melon patch. Low-cost electrified barriers were installed at these 4 access points: 1 swing gate, 2 bump gates, and 1 installation with electrified wires a few inches above the ground. These electrified barriers were a few thousand dollars each at a maximum. Cameras were installed at each gate to document approaching black bears and potential crossings into the melon patch between June and November 2020. The electrified swing gate had 7 black bears approach the gate within 2 m, and none of these bears crossed the gate into the melon patch (100% effective). At first, the two bump gates only had vertical hanging electrified wires. For the two bump gates combined, 35 black bears approached the gates within 2 m, and 30 of these bears crossed into the melon patch (14.3% effective). One of the bump gates was then modified by attaching an electrified net to the vertical hanging wires. After this modification, 19 black bears approached this gate within 2 m, and none of these bears crossed the gate into the melon patch (100 % effective). The installation with electrified wires a few inches above the ground had 34 black bears approach the gate within 2 m, and 1 of these bears crossed the gate into the melon patch (97.1% effective). The electrified barriers can be a substantial barrier to black bears, and they are probably also a substantial barrier to several other large mammal species with paws (e.g. grizzly bears, wolves). Further research and development may be required though for locations that are accessible to the public. In addition, further research and development is needed to make these electrified barriers also a barrier to large ungulates, potentially by making the barriers higher or through a combination with wildlife guards.
