Brazil's government has abolished a vast national reserve in the Amazon to open up the area to mining.
The area, covering 46,000 sq km (17,800 sq miles), straddles the northern states of Amapa and Para, and is thought to be rich in gold, and other minerals.
The government said nine conservation and indigenous land areas within it would continue to be legally protected.
