In 1999 there were two families with 7 people on the Novo River, the northern boundary of the reserve.

The Serra da Cutia National Park is about 12 kilometres (7.5 mi) to the south.

It is in the centre-west Brazilian pediplain, with altitudes around 100 metres (330 ft) above sea level.

The reserve was created in a special army use area, and is administered by the SEDAM-RO.

Since it is so remote, no conservation measures were taken after creation apart from demarcation and the start of the process of land compensation.
