Abstract
The movement of small vertebrates, e.g. endangered or threatened species, into and/or out of defined areas, e.g. construction sites, is controlled by use of a barrier fence which includes an apertured polymeric sheet. The polymeric sheet includes an upper portion which extends upwards from the ground and a lower portion which is buried in the ground. The polymeric sheet is formed by first and second sets of polymeric strands which are bonded to each other and are spaced apart from each other, thus providing apertures. The height and depth of the barrier fence and the size of the apertures prevent the small vertebrates from crossing the fence, and the apertures permit wind and water flow through the barrier fence.
