Road ecology blog: Bighorn sheep (Ovis canadensis) crossing highway at a fence end, Hwy 3, Crowsnest Pass, Alberta, Canada. An example of a fence that may not be long enough. The bighorn sheep crossed right at the fence end. They jumped the guard rail and landed on the road surface. Fortunately this driver saw the animals and was able to stop in time. It is important to start and end fences at locations where the probability of fence-end runs is minimized. The following paper describes where to start and end wildlife fences and it summarizes suggestions for fence-end treatments:

Huijser, M.P., E.R. Fairbank, W. Camel-Means, J. Graham, V. Watson, P. Basting & D. Becker. 2016. Effectiveness of short sections of wildlife fencing and crossing structures along highways in reducing wildlife-vehicle collisions and providing safe crossing opportunities for large mammals. Biological Conservation 197: 61-68.
