According to the rights organization Survival International, a gold rush mentality seems to have taken hold of loggers, ranchers and settlers in the eastern Amazonian state of Maranhão, as intruders bore their way deeper into reserve areas set up to protect the forests of the Awá tribe. In addition to 355 contacted members of the tribe, about 100 Awá remain uncontacted, making them one of the very last groups of nomads still roaming the forests of the eastern Amazon. The majority of the 60 or more uncontacted tribes that still survive in the Amazon inhabit the more secluded and remote western regions on the vast Amazon Basin.
