Fungus is peak prize for alpine herders

Fungus diggers use an ice pick to prod the earth and dig a hole about 10 centimeters deep. After plucking the fungus from the soil, the diggers fill up the hole with the removed earth to restore the natural soil structure for fostering caterpillar fungus in the coming year. During this period, the herdsmen make their home temporarily in tents in the valley.

This year, however, the hunt is different. New rules require herders to obtain permits, designating approved areas and seasonal windows to prevent over-harvesting.
