If wildlife fences are designed and maintained well they can keep wildlife out of the fenced road corridor. However, in landscapes that have substantial human presence and human activity, there are gaps in the fence where the smaller access roads connect to the fenced main road. To keep wildlife from simply walking through these gaps gates or wildlife guards can be installed. Gates can be locked or unlocked, but they require people to stop, get out of their vehicle, and then close the gate once they have passed through it. This not only disrupts traffic flow, but sometimes the gates are left open. For higher volume and higher speed access roads wildlife guards or electric mats embedded in the pavement are more appropriate. Wildlife guards are similar to cattle guards; they are designed to discourage ungulates, particularly deer and elk from walking on top of the guard and access the fenced road corridor.
