Peruvian regional authorities have decided to protect isolated tribes in the Amazon rainforest against the threat of illegal logging, after repeated warnings about their plight. The presence of the indigenous people between Peru and Brazil was revealed in September 2007 by the National Institute of Natural Resources (Inrena) and a Frankfurt-based scientific association. Several international and local NGOs have for months warned the Indians' way of life was jeopardized by illegal loggers and oil exploration. The decision by the Madre de Dios regional government in the southeast came days after officials in neighboring Brazil released dramatic photos of an isolated tribe to draw attention to threats posed by illegal logging and other development.
