'Stench fence' designed to keep deer safe

A so-called “stench fence” along a forest road in the Frienisberg region of the Bernese Seeland, aiming to reduce wildlife collisions.

Nearly 500 posts fitted with odor-treated foam were placed over three kilometers to deter deer from approaching traffic. The smell is designed to mimic predators and humans,

The measure follows nearly 50 deer deaths on this stretch in six years. 

While similar systems have reduced accidents elsewhere, experts remain divided on their effectiveness. 

Nationwide, around 8,000 deer are killed in road accidents each year.
