The Mascho Piro tribe, known for their isolation, had been documented only weeks earlier hunting along the Pariamanú River. The area they inhabit, rich in valuable hardwoods such as mahogany and shihuahuaco, has seen extensive logging activities, with satellite images revealing thousands of kilometers of new roads between 2020 and 2023.
Indigenous groups have called for the expansion of protected areas to safeguard Mascho Piro lands, but face significant resistance from the logging industry, which holds concessions in the region. Concerns also exist about the potential for disease transmission to the Mascho Piro, whose immune systems may not withstand common illnesses brought by outsiders.
The Mascho Piro are considered the world’s largest group of voluntarily isolated people, numbering approximately 750, and typically limit interactions to other indigenous communities.
