Fladry as prevention tool to avoid damage on livestock

Fladry is a line of rope mounted along the top of the fence from which are suspended strips of fabric or coloured flags (usually red) that will flap in a breeze, intented to deter wolves from crossinf the fence-line. Fladry are a temporary but efficient prevention method to avoid damage on livestock  in small pastures as this footage shows.

Wolves – especially older, experienced ones – are often very skeptical of new things in their environment.  For some reason, they don’t like those flags rippling in the breeze.

Part of fladry’s success, it seems, is that it is a new object that causes wolves to become frightened of passing it. Past studies have shown that fladry can be effective in field trials for up to 60 days before wild wolves cross them (Musiani 2003).
