The sheep with glasses with their special rough wool need to live in a comfortable habitat all year round. Unfortunately the valley’s main mountain pasture has gradually been deteriorating over the last few decades. It is only recently that shepherds and a handful of volunteers have attempted to improve the situation, yet there has been a shortfall of maintenance to the extent that the traditional transhumance of flocks in the high alps during the summer months and normal grazing at high altitudes is at risk.
