Fundacion Silataj works with 26 aboriginal communities from the Argentina provinces of Salta, Formosa, Jujuy and Catamarca. The remaining population of the Wichi ethnic group is sparsely distributed in communities in these provinces.

Women weave chaguar fiber dyed with roots, fruits or leaves. Men carve palo santo wood, utilizing dried branches or fallen trees that they collect in the forest. Most Wichi communities still subsist by fishing, hunting, and gathering.
