"Viehscheid" literally translated means "Cattle Separation."It can also be known at Almabtrieb.
In the Alp countries, it is common for farmers to brand their cattle and send them higher up into the mountains for grazing. It's actually important for the cattle to chew down the grass. If the grass stays too long when the snow hits, the snow clinging to the grass causes the grass to be pulled out, roots and all, and leads to a great deal of erosion on the mountain-side. Letting the cows keep the grass "mowed" to a short length is a great benefit. You can get more information in the Bavarian Culture section.
