Passage Through a Small Drainage Culvert by Mule Deer, Odocoilus hemionus, and Other Mammals

Alissa Krawchuk, Karl W. Larsen, Richard D. Weir, Helen Davis


Cameras with infra-red triggers were used to monitor the passage of wildlife through underground passages that ran under a major highway and railway. Several species of mammals were detected traveling through the passages; of particular interest was the movement of Mule Deer (Odocoileus hemionus) through a relatively small culvert that would not have been predicted to see usage by these animals.
