The Naso indigenous people live in Panama and Costa Rica, currently primarily along the Teribe River in the Bocas del Toro province of Panama. The Naso number a little over 4,000 people, and against enormous odds have preserved their language, culture, and way of life. Their traditional lands cover some of the most mountainous and biodiversity-rich areas of western Panama. The Naso, one of only two indigenous groups in Panama for which the government has not recognized their ancestral lands, have been fighting since at least 1973 for legal recognition of their territory.
