Overcoming its ancestral fear of the mountain spirits, a peasant community of 500 families has decided to take its destiny in hand. After decades of intensive deforestation and mining, the community declared itself an "ecological community", transforming its former hunting grounds into a reserve where threatened species, such as the Andean bear, are protected and reintroduced.

Today, the lowlands are devoted to organic agriculture, while the highlands are home to the reserve, whose revenues allow the comuneros to improve their living conditions and mainly finance the development of schools and health services in the hamlets.
