In May of 2007, scientists conducted a rapid inventory in the Dureno Territory, part of the Cofan ancestral territories in the Amazon basin of eastern Ecuador. Presented primarily in Spanish but including sections in English and A'ingae, the language of the Cofan, this assessment collects those scientists' research on the plants and animals of the region, as well as a history of the grassroots conservation efforts of the Cofan. The report closes with recommendations for long-term management of the area.
