Pest-exclusion fence

A pest-exclusion fence is a barrier that is built to exclude certain types of animalpests from an enclosure. This may be to protect plants in horticulture, preserve grassland for grazing animals, separate species carrying diseases (vector species) from livestock, prevent troublesome species entering roadways, or to protect endemicspecies in nature reserves. These fences are not necessarily traditional wire barriers, but may also include barriers of sound, or smell.
