ALTO RIO GUAMA INDIGENOUS RESERVE, Brazil (AP) — Deep in the Amazon rainforest, there is talk of a looming conflict over land.

The men in the Tembe indigenous group sometimes daub themselves in traditional war paint and patrol the forest. They carry bows and arrows, but feel increasingly vulnerable as they brace for run-ins with illegal loggers.

Tension over territory reached a new height after a surge in annual fires, usually set to clear land, devastated large areas of the Brazil’s Amazon region in past weeks. Some indigenous people who live in the Amazon say deforestation is encroaching on their lands and way of life.

The problem is old — and escalating. On Aug. 27, Tembe people who had repeatedly warned loggers to stay out of their reserve took action.

On a forest trek, men from the Tekohaw village spotted loggers using chain saws, trucks and tractors to cut down and haul trees. The indigenous warriors recorded video. Then they intervened, letting the loggers flee before burning their machinery.

“We destroyed their machinery because they have been destroying our lives for a long time. Our life is the forest,” said Ronilson Tembé. On a recent jungle patrol, he was camouflaged from head to foot with leaves and carried a large red horn to summon companions.

The Tembe are proud of their triumph, but worry about retaliation. Police are monitoring makeshift sawmills around their land after the Tekohaw village chieftain filed reports of death threats.

“Every day that passes, the invasion comes closer to our village,” said the chieftain, Sergio Muxi Tembé. He wore a colorful headdress of macaw and other feathers and a traditional bone bracelet on his wrist, next to a Casio digital watch.

“We don’t want to be killed by bullets,” he said. “We want the federal government to assume its responsibility and guarantee the right that we have to live in our lands, to live in peace.”

Their 1,080-square-mile Alto Rio Guama homeland is officially protected. But in reality, it’s under siege by loggers who try to extract prized hardwood in a Brazilian state that is one of the Amazon’s largest producers and exporters of timber.

Like other Amazon states, Para has also been hit by thousands of fires that have intensified international concern about the world’s largest rainforest, considered a vital bulwark against climate change.

An Associated Press team traveled for days in the Amazon to document the fires and deforestation on the remote indigenous reserve, which can only be reached by river or on rough roads.

On a recent day, a boa constrictor slithered in the sun on a red dirt road leading to Tekohaw, where about 600 members of the tribe live on the banks of the Gurupí River. Their life mixes tradition and modernity. Villagers fish for piranhas, hunt for birds, and pick fruits and take materials for traditional medicine from jungle trees, while some watch television or log on to the internet on phones inside thatched-roof huts.
